Forward Deployed Engineer

We are looking for a Forward Deployed Engineer to work shoulder-to-shoulder with our customers, building the solutions that make their AI systems actually work. You'll sit on a customer's team and own outcomes end-to-end, things like: Wiring their applications into Arthur's telemetry and evaluation systems, building custom UI components and dashboards, writing the queries and integrations that expose evals and guardrails to their users, etc.

Just as importantly, you'll serve as a feedback loop back into product, where the patterns you discover building bespoke solutions become the primitives and features that ship to everyone. This is a high-agency, pre-product-market-fit role where you'll validate product hypotheses by building real things for real customers.

The ideal candidate is a versatile, customer-facing builder who thrives on ambiguity and context-switching. You're equally comfortable diving into a customer's codebase as you are sitting in a working session understanding their problem, and you measure your success by whether people use what you build and get value from it, not by owning a single tidy technical domain. You bring genuine startup energy: you'll wear many hats, make bets, change bets, and take real ownership of the company's success.
