Job Technologies
Your role in the team
- As a Senior Applied AI Engineer on our AI Platform team, you take AI at bunch from working to relied upon.
- We already run AI in production - a document extraction pipeline live in fund operations, agent workflows on Mastra, evaluations, and multi-provider fallback inside EU data residency.
- Fund operations run on documents, deadlines and numbers that have to be right - subscription documents to parse, capital calls to chase, portfolio data to reconcile.
- You build on that foundation: more agents taking that work off people's hands, the evaluations that prove they can be trusted with it, and the platform that lets every other team at bunch ship the same way.
- This is end-to-end product engineering, not research: you own architecture, evaluation, integration, and deployment.

Our expectations of you
Qualifications
- Real depth in orchestration and context engineering - tool contracts, memory, RAG, multi-agent design - with Mastra, ai-sdk, LangGraph or similar.
- You've integrated agents into a real product and its authorization model, not built prototypes for someone else to productionise.
- You know how to make a non-deterministic system measurable, from test cases built on real data to regression suites and human review, and you can tell the difference between a model that improved and a benchmark that got easier.
- You own what you ship. Reading traces, diagnosing failure modes, tuning cost and latency, handling provider rate limits and fallback without drama.
- You build for other engineers as much as for end users, and the standards you set get adopted because people trust you, not because they are written down.
- You start from the business outcome, choose the deterministic solution when it's the right one, and know when good enough is good enough.
Experience
- 5+ years of building production software, including at least one agent or LLM-powered capability that you took end-to-end and still owned once it was live.
- You have experience with TypeScript and/or Python.
- Experience in fintech, private markets, or another regulated, document-heavy domain is a plus, as is working under EU data-residency constraints.
