Full-Stack AI Engineer @ MARV

🚀 MARV is hiring: Full-Stack AI Engineer We're building MARV — a multi-agent Legal AI platform and portable trust infrastructure for the agentic economy. Our mission: Think Free®. Across jurisdictions, across languages, across the messy reality of how legal and financial agreements actually get made.We're looking for our an AI engineer in Sweden — someone who can own the full stack, not just the model layer. We're not stitching together someone else's API and calling it a product. We're building our own AI ecosystem — proprietary infrastructure, our own models and orchestration layer, owned end-to-end rather than rented from a third party. If that excites you more than plugging into an existing stack, keep reading. Genuine interest in building proprietary AI infrastructure rather than only integrating third-party model APIs — you want to own the stack, not rent it" — plus a nod to open-source/self-hosted model deployment experience as a plus, which signals you want people who can work below the API layer. What you'll do:Design and ship RAG pipelines over legal and financial documents — embeddings, retrieval, chunking strategies that actually hold up under scrutinyOrchestrate LLM workflows and agentic pipelines that power MARV's core product experienceOwn backend infrastructure end-to-end: APIs, vector databases, cloud deployment, scalingBuild evaluation and guardrail systems to keep hallucination and error rates low in a domain where mistakes matterWork directly with our founding team to shape product, architecture, and roadmap — not just execute someone else's spec What we're looking for:5 to 8+ years of production software engineering experience, with hands-on work shipping LLM-powered features (not just side projects)Real experience with RAG: vector databases (Pinecone, Weaviate, pgvector, etc.), embeddings, and retrieval tuningStrong backend fundamentals — Python and/or TypeScript, API design, cloud infra (AWS/GCP/Azure), containerizationComfort with agentic frameworks (LangGraph, CrewAI, or your own orchestration) is a strong plusA bias toward shipping — you'd rather ship a working v1 and iterate than perfect something in isolationBonus: experience in a regulated industry (legal, fintech, healthcare) where privacy, auditability, and compliance are part of the job, not an afterthought Why join now:This is a founding-level seat — you'll shape the architecture that scales with us, not inherit someone else's. We're building for a multi-jurisdictional, multi-agent future, and we want someone who wantsto build the foundation, not just work on top of it. 📍 Location: flexible / remote-friendly 💰 Comp: equity-forward at this stage, with compensation structured to scale as we close fundingIf you want to build the trust layer for the agentic economy — let's talk.
