Founding AI Engineer

About this role

ABOUT THE ROLE

Join a small, high-velocity team building an AI-powered pricing platform that helps B2B companies continuously optimize their pricing strategy and improve deal outcomes. The AI recommends prices; expert Pricing Architects stay in the loop on high-stakes calls. Your mandate is to build the evaluation systems and feedback loops that let the AI earn more of that trust over time. This is applied AI on a problem where quality is directly measurable in customer revenue.

WHAT YOU'LL DO

- Design and build eval harnesses and benchmarks that use tracked pricing outcomes as ground truth for AI recommendations.

- Own LLM infrastructure and model routing across multiple frontier providers (Anthropic, Google) with explicit cost/latency/quality tradeoffs.

- Maintain EU data-residency boundaries for EU customer model calls, ensuring compliance with applicable data regulations.

- Extend an MCP server so LLM agents — including customers' own agents — can programmatically drive the platform.

- Build observability and feedback loops that surface where the AI earns or loses trust from human reviewers.

- Bridge non-deterministic engineering concepts clearly to less technical stakeholders (sales, customer success, leadership).

WHAT WE'RE LOOKING FOR

Required

- 8+ years of software engineering experience with strong, recent production LLM depth.

- Demonstrated track record of shipping and owning LLM-powered product features in production — not research-only work.

- Has personally built evals and observability for LLM systems (not just consumed someone else's dashboard).

- Comfortable operating across the full stack: TypeScript/Python, FastAPI, GCP, and modern LLM tooling.

- Strong communicator who can make non-deterministic engineering concepts legible to non-technical stakeholders.

Nice to Have

- Experience with MCP or building tools/integrations for LLM agents.

- Familiarity with LangChain, LlamaIndex, Braintrust, Langfuse, or OpenRouter.

- Background in a domain where correctness is audited — pricing, billing, payments, or similar.

- Experience at a seed-stage or founding-team environment; comfort with AI-assisted coding workflows (e.g., Cursor, Claude Code).

TECH STACK

- Languages & Frameworks: TypeScript, React, Python, FastAPI

- Infrastructure: GCP, Pulumi, Cloudflare Pages, MongoDB Atlas

- AI/LLM Tooling: FastMCP, Langfuse, Anthropic Claude, Google Gemini

COMPENSATION & BENEFITS

- Salary: €130,000 – €165,000 annually

- Equity: Meaningful employee stock option plan (ESOP)

- Visa sponsorship is not available for this role.

LOCATION

This is a fully on-site role based in Amsterdam, Netherlands. Candidates must be able to work on-site; remote work is not available for this position.
