Team Summary

We're looking for a Principal Software Engineer who keeps a large, distributed platform fast, stable, and efficient as load and complexity grow. This is a role based in our Stockholm office, embedded in a team that owns and operates what it builds.

What You'll Do

• Own projects end-to-end from an architectural standpoint - driving them independently from requirement-gathering through design, delivery, and operation, with minimal oversight.
• Gather and validate requirements, translate them into high-level and low-level designs, and raise the quality bar on designs produced by others.
• Make, document, and review architectural decisions, articulating trade-offs clearly to both technical and non-technical stakeholders.
• Own non-functional attributes - performance, stability, scalability, and availability - and ensure systems meet internal standards.
• Profile real production systems, identify bottlenecks, manage memory and resource usage, and tune latency and throughput across distributed, event-driven services.
• Level up the people around you - share knowledge, review designs, and influence both technical and business decisions in the right direction.

What You'll Need

• Senior-level experience building and operating production software.
• A track record of architecting, building, and running distributed systems at real scale: cloud, Kubernetes, event-driven architectures.
• Strong performance-engineering background: profiling, benchmarking, memory management, concurrency, and tuning systems under real production load.
• The ability to make architectural decisions and explain trade-offs to engineers and non-engineers alike.
• Strong fundamentals: system design, data structures, concurrency, and API design.
• Clear communicator who enjoys making the people around them better.

Why Join

• Deep, hands-on exposure to how complex investment software is built and run alongside our multidisciplinary team which is based out of the same office in Stockholm.
• Work on a modern, open, cloud-native platform with the collaboration and humility of the team Limina was built on.
• Flexible hybrid working and a modern office in central Stockholm, with a global platform and client base behind you.
