In Tech, our vision is to move toward AI-first, automated and data-driven systems — not by adding AI on top of legacy workflows, but by redesigning how software is built and operated. We focus on scalable, observable systems owned by engineers end-to-end. We are now looking for Senior Full-Stack Software Engineers who want ownership, impact and engineering challenges. The Role As a Senior Full-Stack Software Engineer, you will design, build and operate distributed backend systems and modern frontend applications that power Apotea’s core products and emerging AI-driven experiences. You will own the full software lifecycle: architecture, implementation, deployment, monitoring and improvement — from database design and backend services in Go to frontend experiences for teams and customers.

Key Responsibilities Full-Stack System Design & Implementation: * Design and build backend services in Go for distributed, cloud-native applications. * Build frontend applications that connect users to data, workflows and AI-powered capabilities. * Build APIs and event-driven components across e-commerce, logistics, data and AI platforms. * Design systems with scalability, resilience and observability in mind. Database Design & Data Ownership: * Design application-level data models and database schemas. * Make informed trade-offs between storage approaches. * Understand query patterns and performance implications. * Integrate operational systems with analytics and ML pipelines. Agentic AI Applications: * Build production-grade agentic AI applications that integrate LLMs with real systems and workflows. * Design services that enable AI agents to act safely with business data. * Collaborate with ML and data engineers to operationalize AI in real products — not demos. * Help define guardrails and patterns for reliable AI-driven systems. Engineering Excellence: * Write clean, maintainable, production-quality code across backend and frontend. * Participate in code reviews and architectural discussions. * Build automated tests and CI/CD pipelines. * Take responsibility for production reliability and incident resolution. * Improve engineering standards, tooling and AI-assisted coding workflows. We are looking for someone with: * Strong experience as a Senior Full-Stack Software Engineer building production systems. * Proven experience with Go (Golang) in backend environments. * Solid understanding of distributed systems and modern architectures. * Experience building frontend applications. * Experience with database design and application data modeling. * Strong fundamentals: testing, versioning, CI/CD, documentation and code quality. * Ownership mindset and ability to balance speed and quality. * Excellent communication skills and collaborative attitude. Nice to Have * Experience with A/B testing or experimentation frameworks. * Familiarity with event-driven architectures and streaming systems. * Experience with AWS and cloud-native architectures. * Experience building AI-powered or agentic applications. * Exposure to high-scale e-commerce, logistics or data-heavy environments. * Knowledge of Infrastructure as Code, such as Terraform, CDK or CloudFormation.

Anyfin

Anyfin is building the next generation of consumer finance. We’re profitable, scaling quickly and now operating with a banking license which opens up a lot of technical complexity. We’re looking for a senior cloud engineer who enjoys moving fast, taking real ownership and building systems that actually have an impact. If that sounds like your kind of environment, keep reading. Because honestly, it’s not a role for everyone. SMALL TEAM, HIGH RESPONSIBILITY We hire carefully. We’re not a company that grows by adding headcount everywhere, we grow by keeping the bar high and building a team where every person matters. This isn’t a place where you disappear into a big org. If you join, you’ll have real influence on what we build and how we build it. WHAT YOU’LL DO * Designing, deploying and operating cloud infrastructure and services on GCP to support scalable and reliable systems. * Building, optimizing and scaling backend systems with a cloud-first mindset, using Node.js and SQL (Postgres). * Contributing to system architecture to ensure cloud scalability, reliability and maintainability of financial systems. * Collaborating closely with cross-functional teams to shape both product direction and business strategy. * Sharing cloud and infrastructure expertise with the team while promoting best practices. Our main stack is TypeScript, Node.js, React, React Native running on Google Cloud Platform. HOW WE THINK ABOUT BUILDING We’re pragmatic. We like speed, but we also care about building things that last. AI isn’t a side tool here. It’s embedded in how we work helping engineers move faster, reduce friction and focus on solving meaningful problems. We’re looking for engineers who are curious about that shift and want to be part of it, rather than people who feel like good engineering means doing everything the hard way. No ego. Just good judgment and high output. YOU’LL THRIVE HERE IF YOU… * Have solid experience building backend systems with cloud-first practices and working with cloud platforms such as GCP, AWS, or Azure. * Care about craftsmanship, performance and reliability in the systems you build. * Take responsibility naturally and don’t wait to be told what to do. * Enjoy messy problems and figuring things out as you go. * Like being in an ambitious and collaborative team. * Want to build, not just maintain. You’re comfortable with things like: * Strong background in cloud infrastructure and backend development with Node.js and SQL databases (preferably Postgres). * Experience in designing, deploying and monitoring solutions on major cloud platforms such as GCP, AWS, or Azure. * At least 5 years of professional experience, ideally in high-stakes environments like finance. * Passionate about solving complex backend and cloud problems with clean, pragmatic solutions. * Solid understanding of system design and architecture. * Bonus if you’ve worked with React, Python, Go, GraphQL, Kubernetes, or DevOps with Github Actions. A FEW PRACTICAL NOTES * Stockholm based. * EU work authorization required WHY ANYFIN? Because this is one of those moments where a company is about to level up: Banking license secured, expansion ahead and a lot to build. If you want to be part of a small, high-trust team doing meaningful work, we’d love to hear from you. Apply only if you want the responsibility that comes with real impact.
