Senior Backend Engineer

Open position Senior Backend Engineer About Us We build software that makes governance, risk, and compliance approachable: turning dense regulatory frameworks and internal policy into something organizations can work with. AI is central to how we do that, surfacing the right information, making sense of complex documents, and keeping outputs trustworthy in a domain where accuracy matters. We were founded by Magnus Juvas, serial entrepreneur behind Solidify and Transcendent Group, and Emelie Alftrén, with over two decades in risk management and governance. Two people who had seen the problem from both sides and decided to solve it properly. We're early-stage, meaning the foundations are in place but there's plenty left to shape. You'll have real ownership over both what you build and how it evolves. We're based in Stockholm and work hybrid. Joining Nooga means three things. Own it: we take responsibility and act. If you see a problem, you step up. Challenge the norm: we don't build things the way they've always been built. We build them better. Succeed together: with each other, and with our customers. Role Overview You'll own and evolve the backend systems at the core of our Navigator platform: including the document processing pipeline, job execution, the retrieval and query layer, and the APIs that surface it all. You work in a Kubernetes environment, running, changing, and extending application workloads, and you think about how the system scales and where it needs to go next, not just what it does today. You're someone who wants to grow into technical leadership. You have opinions about how things should be built, you're critical about what actually needs to be solved now, and you bring the same pragmatism to architecture as you do to delivery. You're curious about the wider system, not just your slice of it. What You'll Work On The document processing pipeline: Celery-based orchestration, job execution, failure handling, and observabilityLLM integration: prompt engineering, structured output, multi-provider orchestration (Anthropic Claude, OpenAI, OpenRouter)The retrieval layer: Milvus vector store, chunking strategies, embedding quality, re-rankingFastAPI services and the query surface that backends the assistantApplication workloads on Kubernetes: deploying, scaling, and evolving how backend services runPostgreSQL data modelling, including graph features via Apache AGEContributing to how the system evolves, not just executing, but helping shape what comes next What We're Looking For 5+ years building production backend services (ours is using Python); strong on typing, testing, and clean codeHands-on experience with LLM APIs in production: prompt design, structured outputs, evaluation, cost/latency trade-offsExperience with vector databases and RAG (Milvus, pgvector, or similar): embeddings, indexing, retrieval qualitySolid experience with distributed task systems (Celery + Redis, or comparable)Comfortable working in and reasoning about cloud-hosted Kubernetes environments: deploying and operating application workloads with an awareness of cost and scaleComfort with relational databases and async web frameworks (FastAPI or equivalent)Opinionated about engineering quality, pragmatic about what to build now versus laterWants to grow: you're thinking about the wider system and where it's heading, not just your current taskBuilt solutions that run on Azure (including AI Foundry, Blob Storage, AKS) or comparable experience on AWS or GCP and open to ramping up knowledge Helpful But Not Required Apache AGE or other graph databasesExposure to regulated industries (GRC, finance, legal, healthcare) What We Offer Competitive salary and benefits.Office in central Stockholm with a flexible hybrid environment.Career growth and development opportunities.
