We’re excited about what’s next, and we’re looking for others to join us on our journey. SENIOR SOFTWARE ENGINEER - GOVERNMENT CLOUD We're hiring a software engineer to join the team responsible for bringing Tines to federal customers in AWS GovCloud. You'll build and improve the product features and tooling that make Tines work seamlessly in a compliance-regulated environment, ensuring federal customers have the same powerful experience as our commercial users — while meeting the security and operational requirements unique to the government. This role is about more than writing code: you'll have an influential voice in shaping our technical direction, our product, and our culture. We have a hugely supportive and collaborative engineering team that takes great pride in the work we do and the challenges we solve. We're eager to help grow and nurture each other's abilities and also create an environment where we have the ability to do our very best work. LOCATION: You can work fully remotely from anywhere in the US with a preference for being based in the Greater Boston Area. Here, you can make use of our Tines office space in downtown Boston to meet up with other members of the MA engineering team when you wish.  Due to the nature of this role and associated U.S. Government customer requirements, applicants must be U.S. citizens and must perform work while located within the United States. WHAT YOU WILL BE DOING: * Design, build, and harden product features within a compliance-regulated cloud environment — writing code with a strong focus on security controls, data privacy, and auditability. * Building features specific to AWS GovCloud users: authentication methods required by federal agencies, audit and compliance capabilities, and tooling that makes it easier for customers to operate and audit their own Tines tenants. * Building abstractions that reduce friction for engineers across Tines to author and test features in a government cloud environment without needing direct access to it — environment-aware configuration, feature flags, and automated compliance boundary testing. * Enabling software engineers to build new product features that work seamlessly across commercial and government cloud environments: observability, logging, and simplifying deployments. * Analyzing our application for security gaps, identifying where existing functionality needs to be adapted, constrained, or hardened to meet government standards — and implementing those changes yourself. * Working cross-functionally across product teams to align timelines and develop hands-on solutions that meet security controls, translating between compliance requirements and engineering reality. * Using your knowledge and experience to mentor other engineers on secure design patterns and building confidently for regulated environments. * Supporting our self-hosted federal customers operating in our CMMC environment, including handling escalations and complex, long-running support cases as part of the team's on-call responsibilities.   PROJECTS YOU MIGHT WORK ON: * Building smart card authentication support so federal users can log in with their government-issued credentials alongside existing SSO integrations. * Making it easier for customers to operate and audit their own Tines tenants — richer audit logging, records retention controls, and exportable compliance evidence. * Building developer tooling and abstractions so engineers across Tines can author features that work in GovCloud without needing to understand every compliance constraint — automated testing that catches compliance boundary violations before they reach production. * Implementing security impact analysis and change control workflows directly into our development process, so compliance validation is part of shipping code rather than a separate step. * Ensuring our GovCloud SaaS and self-hosted customers can easily monitor, manage, and scale their dependencies like OpenSearch — building the in-product features and tooling that give customers visibility and control over their own infrastructure. * Collaborating closely with our Product and Design teams to determine which product capabilities need to be adapted or constrained for government environments — and finding the simplest path to get there. * Using our own product to automate compliance workflows — vulnerability tracking, change control documentation, and incident response runbooks powered by Tines. * Writing a blog post to share something interesting we learned about building for the government with the community. IS THIS THE RIGHT ROLE FOR YOU? * Roughly 7+ years as a professional software engineer. Proven track record of success as a senior software engineer. This is a senior role and we're looking for candidates with a well of experience to draw from. * You'll need direct experience of building and delivering software using a high-level programming language. Our interview process includes some hands-on coding. You can use a language you're comfortable with to complete the coding section. * Experience building software that operates in compliance-regulated or security-sensitive environments is a strong plus. You don't need to be a FedRAMP expert, but if you've worked in an environment where design decisions need to be documented, justified, and auditable — whether that's FedRAMP, FISMA, SOC 2, HIPAA, or similar — you'll understand the constraints we're working within. * You're comfortable reasoning about security at the application layer. You should be able to look at a feature and identify where it needs to handle encryption, access control, audit logging, or data retention differently for a government deployment — and implement those changes yourself. * Your abilities matter, not your education or exactly where you've worked. We just need you to show us that you have accumulated the foundational skills and knowledge needed to succeed. Our main languages are Ruby and TypeScript, but you don't have to be familiar with those — we value curiosity and an eagerness to learn. We'll also cover the cost of education material to bring you up to speed. * This role is broad, not specialized. While your main focus will be on building product features for our government cloud offering, you'll work right across our stack. You don't need to have experience in all of these areas, but you will need to be excited to pitch in anywhere when needed, with the support of your teammates. This allows us to be more effective as a team, and provides a lot of opportunities for you to learn. * You are customer obsessed and willing to go deep into unfamiliar stacks to find root causes for errors, performance issues, and bugs. You understand that the best solution isn't always the best technical solution, but a compromise that meets customers where they are. * We're focused on the most important problems, not the most interesting ones. Your time and energy are limited, so in order to succeed you'll need to spend it where it will make a difference. We view technologies as a means to an end, and stick to simple, common tools — Ruby, Rails, React, TypeScript, Postgres, Redis, AWS CDK, and Kubernetes. * We work healthily and sustainably. We work reasonable hours, we take our holidays and we plan our workloads realistically. No matter how excited we get by a project, it's more important to not get burnt out from overwork. * Your contributions will be obvious. On a small team like ours, you don't have to spend a tonne of time and energy making sure your work is seen — your impact will be clear to everyone. * We're building an inclusive, supportive team. We have a wonderfully wide spectrum of colleagues at Tines, and we treat them all with kindness and respect — we expect that you will too. We don't hire people that treat their colleagues badly, no matter how talented they are.

Our mission is simple: to make self-custody accessible and give people the keys to their own financial futures. If you want to make a true impact, we want you to join us at Ledger. At Ledger, we’re proud to be the global platform for digital assets and Web3, with over 20% of the world’s crypto assets secured through our Ledger devices. With our headquarters in Paris, and offices in Vierzon, Grenoble, Montpellier, London, Portland, Geneva, Zurich and Central Singapore, we have a team of around 600 professionals developing a variety of products and services to enable individuals and companies to securely buy, store, swap, grow and manage crypto assets – including the Ledger hardware wallets line with more than 7.5 millions units already sold in 200 countries. The team You will join the Security Operations team, which is responsible for protecting Ledger’s corporate, cloud, SaaS, and data center environments. Its mission is to anticipate, detect, investigate, and respond to cyber threats—including monitoring, alert triage, incident response, detection, visibility, automation, exposure tracking, and continuous process improvement. This scope is distinct from that of the Donjon (product security): SecOps covers the operational security of internal environments, the cloud, endpoints, workloads, identities, and infrastructure. As a close-knit and experienced team—technically rigorous and committed to knowledge sharing—we are also continuously building the SOC itself: integrating new log sources, ensuring data quality, expanding detection coverage, and developing reliable dashboards and operational workflows. Our technical stack includes: * Splunk for SIEM, investigations, and dashboards; * CrowdStrike for EDR and endpoint/workload security; * Wiz for cloud security and exposure management; * Torq for SOAR and automation; * AWS, including modern environments such as EKS/Kubernetes; * An in-house, internally developed Agentic SOC for alert enrichment, correlation, investigation support, reporting, and automation. AI is at the heart of how we work: investing in AI applied to security is a strategic priority for Ledger this year. We’ve built our own in-house Agentic SOC, which autonomously investigates weak signals—the large volume of unreliable alerts that a human team couldn’t sort through manually—and enriches them, so our engineers can focus on what matters most and resolve incidents faster: high-quality detection, reduced noise, and accelerated investigations. What you’ll be doing: As a Senior Security Operations Engineer, you are at the heart of the SOC: you lead investigations from start to finish, manage the lifecycle of detections, dashboards, and automations, and continuously expand our visibility (cloud, endpoints, identities, SaaS, infrastructure). You work independently on complex issues, decide on the next steps - investigation, containment, remediation, or escalation - serve as a technical resource and point of escalation for more junior analysts (whose work you review and with whom you share your knowledge), and make a tangible contribution to improving our internal Agentic SOC. Operate the SOC * Analyze, classify, and prioritize alerts (from Splunk, CrowdStrike, Wiz, AWS, and other sources), and conduct in-depth investigations into incidents affecting endpoints, the cloud, identities, SaaS, workloads, and infrastructure. * Provide clear, actionable context to inform next steps, and serve as an escalation point for less experienced analysts. * Leverage the Agentic SOC, which investigates weak signals and enriches alerts, so you can focus your time on the incidents that matter. Visibility & Detection * Build and tune cloud detection use cases (AWS, IAM activity, EKS/Kubernetes, container workloads), and use Wiz to track and prioritize cloud exposure as part of your detection work. * Integrate and maintain the necessary log sources (cloud, endpoints, identities, SaaS, infrastructure, Kubernetes) and improve data quality: completeness, parsing, normalization, relevance, and usability. * Identify visibility blind spots and work with the IT, Cloud, Infrastructure, and Engineering teams to reduce them. * Design, write, and optimize Splunk queries; develop new detection use cases based on available logs, refine them, and document their logic; reduce noise and improve signal quality. Incident Response * Play a leading role in investigations: gathering evidence, reconstructing timelines, and documenting actions taken. * Monitor containment, remediation, and post-incident measures. * Turn lessons learned into sustainable improvements and formalize processes: detection mechanisms, runbooks, dashboards, and automations. Contribute to automation and our Agentic SOC * Build and maintain automations (Torq/SOAR, scripts, APIs) that accelerate triage, enrichment, and response. * Contribute to the design and continuous improvement of the internal Agentic SOC—the AI system that investigates weak signals, enriches alerts, and assists with investigations—and expand its capabilities: new investigation workflows, better correlation, and tighter integration with detection and response. What we’re looking for: * Solid & proven experience in SecOps, SOC, cloud security, incident response, or infrastructure security, with a track record of building and improving SOC capabilities (logs, detections, dashboards, automations, runbooks, workflows) and conducting independent investigations. * Comfortable working in cloud and SaaS environments and with rapidly evolving technologies. * Proficiency in SecOps fundamentals: triage, investigation, incident response, log analysis, and documentation. * Strong, hands-on cloud security skills (ideally AWS): investigating IAM and identity activity, analyzing cloud audit logs (e.g. CloudTrail, GuardDuty), securing workloads, containers, and Kubernetes (EKS), and scoping cloud incidents end-to-end. Comfortable with exposure/CSPM tooling (ideally Wiz). * SIEM (ideally Splunk) with the ability to write queries for investigation and detection; EDR (ideally CrowdStrike). * Automation using Python, Bash, APIs, GitHub Actions, SOAR, or equivalent. * Interest in—or experience with—AI applied to security, agent-based workflows, and SOC automation. * Diligence, independence, technical curiosity, and attention to detail. * Ability to conduct in-depth investigations, document findings clearly, and escalate issues with the appropriate level of context; awareness of confidentiality and the proper handling of sensitive information. * Professional-level English; Ledger operates in an international environment.
