The Opportunity: Your Next Big Leap @Qover
You’re not looking to churn through tickets — you want to build systems that matter, at meaningful scale, alongside a team that values strong engineering.
At Qover, you’ll help power embedded insurance experiences used by leading brands like Revolut, Mastercard, BMW, and Monzo. Our platform operates across 32 countries and supports millions of end users through our partners.
We’re entering our next phase of growth and investing in the reliability, scalability, and developer experience of our platform. We’re looking for engineers who care about clean architecture, pragmatic decision-making, and building software that lasts.
Your Impact: What You’ll Do
As a Sr. Full-Stack Engineer at Qover, you’ll take ownership of complex features end-to-end — from design discussions through implementation, deployment, and monitoring. You’ll contribute to architectural decisions and help evolve our platform as we scale. Here is a taste of what you will be working on:
● Use AI thoughtfully — in development and beyond: We encourage responsible use of AI-assisted tools to improve productivity, code quality, and documentation. You’ll also have space to explore where emerging AI capabilities could meaningfully enhance our product, in collaboration with engineering and product leadership.
● Design and evolve scalable services and APIs: You’ll build and maintain Node.js services and React applications that support high availability, strong performance, and international scale.
● Build for performance and reliability: You’ll design data models in MongoDB, optimize API performance, and ensure services are observable, testable, and resilient. Because leading global brands rely on our platform, you’ll ensure our integrations are reliable, secure, and performant. Our infrastructure runs on Google Cloud, and we continuously improve our deployment, monitoring, and scaling practices.
● Design with security and privacy in mind: You’ll implement secure authentication and authorization flows, protect sensitive data, and follow best practices for compliance and data protection.
● Contribute to a strong engineering culture: Through code reviews, knowledge sharing, and mentoring, you’ll help raise the technical bar across the team.
Your Arsenal: The Skills You Bring
● Strong professional experience building and operating production systems (typically 5+ years).
● Strong engineering fundamentals and architectural thinking. We operate a microservices-based platform using Node.js, React, and MongoDB. Experience with distributed systems, service boundaries, and API design is important.
If you come from ecosystems like Java, C#, Go, or Python and have successfully worked in production systems at scale, we value your ability to adapt.
● Strong sense of ownership and accountability. You take responsibility for the quality, security, and maintainability of what ships — and you provide thoughtful, high-signal code reviews.
● Experience designing and maintaining robust RESTful APIs.
● Strong Git skills and familiarity with CI/CD pipelines and automated deployments.
● Experience integrating third-party services and managing data consistency across systems.
● Experience working with cloud environments (GCP preferred). Familiarity with containerization and orchestration (Docker, Kubernetes) is a plus.
The Vibe: Who You Are
● The Pragmatic Builder: You care about clean, readable code and details — and you know when to prioritize shipping and iteration.
● The Adaptable Explorer: You’re comfortable in a scale-up environment: shifting priorities, ambiguity, and finding the highest-impact work.
● The Communicator: You communicate clearly in writing and in conversation, ask good questions, and collaborate well across functions.
● The Fun Co-Worker: You’re constructive, kind, and collaborative. You enjoy sharing knowledge through code reviews, pairing, and mentoring.
Your Support System: What We Give You
● Hybrid & remote-friendly: We welcome candidates across Europe. Our Brussels office is a key collaboration hub, and many team activities take place there, but we support flexible remote arrangements and up to one month per year working from anywhere globally.
● A Hub When You Want It: Full access to our dedicated space at WeWork in Brussels (Rue du Commerce 31) for when you want collaborative whiteboard sessions or legendary team events on the terrace.
● Exceptional Culture: A deeply collaborative, inclusive community where you are valued for exactly who you are, regardless of nationality, gender, age, sexual orientation, disability, or background.
● Massive Growth: You’ll join during a high-growth phase, with opportunities to influence our core platform architecture, backend microservices, and overall developer experience.

ABOUT EYE SECURITY Eye Security is an international scale-up providing cyber security with embedded cyber insurance to SMBs in Europe. Our cyber security innovations, state-of-the-art automation and platforms are being built and maintained by our Product and Engineering Teams. Our engineers and product managers collaborate closely with cyber security experts to ensure that their hacker's mindset is embedded into our platform. Our platform is a proprietary Open XDR (eXtended Detection Response) system that brings in security data from several market leading cyber security products into our centralised repository. From here cyber security experts can work their magic. This makes sure that our hundreds of customers experience the same value via automated systems, allowing us to scale in Europe. ABOUT THIS ROLE We're looking for a Senior Engineer to join one of our stream-aligned engineering teams. At Eye, we organise engineering around streams: mission-driven groups with a clear outcome to drive, not a product area or a section of the codebase. You'll work in a small, full-stack team of 2-3 engineers contributing to your stream's goal, working across whatever systems and layers are needed to deliver it. This is a role for someone who wants real ownership, not a queue of tickets. IN THIS ROLE * Own features end-to-end as Feature Lead: scope the problem, coordinate work within your team, make day-to-day technical decisions, and ship it to production. * Deliver high quality features both individually and with other team members, working full-stack across whatever the stream requires. * Collaborate with internal stakeholders to design and develop features that deliver real-world value. * Contribute to technical decision-making within your stream, including surfacing tradeoffs and risks early. * Participate in creating a psychologically safe and happy environment within the team and the company. * The role is remote in the Netherlands or in Berlin, but you commit to travelling to the office (The Hague or Berlin) twice per week. WHAT YOU WILL NEED * 5+ years of development experience, including meaningful full-stack exposure. You are comfortable working across backend and frontend layers and you pick up new technologies independently. * Experience with strongly typed languages (i.e., Typescript, Java, dotnet, PHP). We operate in Go and React, and we back ourselves to get a seasoned engineer with strongly typed experience up to speed in our tech stack quickly. * Comfortable using AI coding tools as part of your daily development workflow, and curious about how AI can improve how we build. * Excellent communication and collaboration skills, with the ability to influence technical and non-technical stakeholders. * Knowledge of secure coding practices and understanding of secure development principles to building safe, trusted systems * Fluency in English is a must. WHAT WE OFFER * Work on genuinely hard problems in a complex domain: XDR, security data at scale, and tooling that empowers security analysts to protect hundreds of customers across Europe. * Real ownership in a small, autonomous team where every engineer is close to the work, close to the decision-making, and close to the impact. * A deliberate bet on AI-augmented engineering: we are building toward small teams that punch well above their weight through smart AI adoption, and you will be part of shaping how that works in practice. * Be at the forefront of innovation, shaping the future of our technology infrastructure. * Enjoy a competitive compensation package and comprehensive benefits. * Join a young and thriving scale-up which is on its way to becoming the category leader in Europe. * We are a great place to work, filled with people who enjoy working together. We are a rapidly growing company and believe in investing in our people. If you're a highly motivated and results-oriented engineer with a passion for building secure, scalable technologies, we encourage you to apply!
ABOUT VERCEL: Vercel is the agentic infrastructure company. We free people and agents to ship what’s next. For more than a decade, Vercel has shaped how the web is built. As the team behind Next.js, v0, and AI SDK, we create products that help builders move from idea to production with speed, security, and exceptional developer experience. Now, software is entering a new era, and the next generation of products will not just be used by people. They will be built, extended, and operated by agents. We are building the platform for that future, trusted by companies like OpenAI, PayPal, Ramp, Supreme, and millions of developers worldwide. Whether you’re building our products, supporting our customers, growing our community, or shaping our story, you’ll help define what comes next. ABOUT THE ROLE v0 turns natural language into working, deployed applications. An agent writes code, executes it, and ships it on a user's behalf. That makes v0 one of the most interesting and highest-stakes security surfaces at Vercel: sandboxed code execution, multi-tenant isolation, permission boundaries between what a user asked for and what the agent actually did, and resistance to prompt injection and tool misuse. We're looking for a Senior (IC4) software engineer with a strong security background to sit fully embedded inside the v0 team, not as a rotating auditor who reviews designs and files tickets, but as a peer engineer who owns security end to end for everything v0 ships. That means finding and fixing vulnerabilities yourself, building security features directly into the product, reviewing every new feature and launch before it goes out, and running the relationship with our HackerOne researcher community for anything v0-related. You'll spend real time being a great generalist engineer: building features, fixing bugs, shipping to production alongside the rest of the team. The difference is that you bring security judgment and hands-on ownership to everything the team builds, and you're the one who catches the sandbox escape, the auth gap, or the injection vector before it ships, rather than after. This role reports into the security organization but is deployed full-time with v0, and is evaluated as much on shipped product velocity as on security outcomes. As a senior (IC4) engineer, you're expected to operate independently, set the security bar for the team, and be trusted to make the final call on v0-specific tradeoffs. WHAT YOU WILL DO * Find and fix issues yourself: Proactively hunt for vulnerabilities across v0, from code you're reviewing to systems you're actively poking at, and ship the fix, not just the finding. * Build security features directly into the product: Design and implement the security-facing functionality itself (sandboxing/isolation controls, permission boundaries, abuse detection, safe defaults for generated apps) as a normal part of the v0 roadmap, not a side project. * Review all new v0 features and launches: Be the security reviewer of record for everything the team ships (new capabilities, generated-app patterns, integrations) before it goes out the door. * Own the HackerOne relationship for v0: Triage, validate, and drive fixes for reports from Vercel's HackerOne researcher community that touch v0, and work directly with researchers on reproduction and remediation. * Own the v0 threat model: Understand and continuously refine how v0 generates, executes, and deploys code, including sandbox/runtime isolation, permission boundaries between agent actions and user intent, and defenses against prompt injection and tool-use abuse. * Harden code execution boundaries: Work directly on how agent-generated code is scoped, sandboxed, and constrained before it touches real infrastructure, including Vercel's own sandbox and serverless runtimes. * Build guardrails that don't slow the team down: Create patterns, libraries, and checks that let v0 engineers ship new generated-app capabilities quickly without reintroducing known bug classes (auth, SSRF, injection) each time. * Partner with central Product Security: Share threat models, incident learnings, and SDLC tooling with the broader security team, while making the final call on v0-specific tradeoffs since you have the deepest context on the product. * Respond to v0-specific security reports and incidents: Be the first responder and technical owner when a security issue is reported against v0 specifically. * Think like an attacker, and like an agent: Reason about how a user, or an agent acting on that user's behalf, could misuse v0 to attack itself, other tenants, or the platform underneath it. ABOUT YOU * You're a software engineer first: 5+ years building and shipping production web applications, at a level where you operate independently (IC4/Senior). You can pick up a normal feature ticket and ship it end to end, this is not a pure audit/review role. * Strong full-stack fundamentals: Comfortable in TypeScript, React, and Node, and able to work in the same codebase, PR flow, and velocity as the rest of the v0 team. * Real security judgment: You understand authN/authZ design, sandboxing and isolation, injection vulnerability classes, and can reason about "an AI agent writing and running code" as a novel attack surface, even if your background so far has been primarily software engineering rather than a security title. * You influence through code, not just process: You'd rather fix the root cause in a PR than write a policy doc about it. You can be the security conscience of a fast-moving team without becoming its bottleneck. * Comfortable with ambiguity: v0's threat model is still being written. You're excited to define it rather than inherit a mature playbook. * Willing to build with v0, not just secure it: You're happy to actually go use v0 to build things and understand how our products work end to end, not just read the code from the outside. BONUS IF YOU HAVE * Already a v0 user or familiar with how it and Vercel's broader product line work. * Hands-on experience with sandboxing, container isolation, or multi-tenant systems. * Done prompt injection / jailbreak / LLM application security research on an agentic or AI-powered product. * Previously shipped a coding agent, dev tool, or code-generation product end to end. * Relevant security certifications (OSCP, OSWE) or notable bug bounty / CTF history. Nice to have, not required for this role. * Enjoy building content and talking publicly about your work: blog posts, conference talks, or research writeups. We'd love for this role to help tell the story of how v0 approaches security, not just do the work quietly. BENEFITS: * Competitive compensation package, including equity. * Inclusive Healthcare Package. * Learn and Grow - we provide mentorship and send you to events that help you build your network and skills. * Flexible Time Off. * We will provide you the gear you need to do your role, and a WFH budget for you to outfit your space as needed. The San Francisco, CA base pay range for this role is $208,000.00 - $312,000.00. Actual salary will be based on job-related skills, experience, and location. Compensation outside of San Francisco may be adjusted based on employee location. The total compensation package may include benefits, equity-based compensation, and eligibility for a company bonus or variable pay program depending on the role.
