You’ll work across backend, orchestration, retrieval, and product-integrated AI systems.

Everything you ship will directly shape how legal teams review, revise, and negotiate contracts inside Word and the browser.

Responsibilities

Own major product surfaces that rely on retrieval, structured reasoning, and multi-step AI pipelines

Prototype, evaluate, and productionize new AI workflows for contract review, clause-level analysis, playbook enforcement, and multi-document tasks

Improve our internal LLM orchestration layer, prompt-library, evaluation tooling, and RAG strategies

Partner with founders and our in-house legal team to design and validate new features

Build backend services that support multi-tenant enterprise customers and high-volume workloads

Ship quickly: small PRs, fast iteration cycles, functional releases every week

Qualifications

7+ years of engineering experience

Strong backend engineering skills and ability to build production systems end to end

Experience shipping ML or LLM-powered products at scale

Experience with retrieval, embeddings, experimentation, and evals

Ability to design multi-step pipelines and agentic workflows

Strong instincts around latency, reliability, and fallback strategies

Ability to prototype in days and productionize in weeks

High standards for correctness, reliability, and UX quality

Bonus: Go, Next.js/React, Postgres/pgvector, Cloud Run, multi-provider LLM orchestration

What You'll Work On:

Designing a multi-step agent that analyzes an entire contract, applies playbooks, generates redlines, and formats them into Word-ready output

Improving a retrieval layer that handles 300+ page agreements or mixed corpuses of PDFs, templates, and prior negotiations

Building a system that scores clause-level correctness using structured evaluation datasets

Creating a streaming, long-running workflow for contract review with checkpoints, retries, and deterministic outputs

Designing a prompt-library and golden-file test suite that guarantees consistent outputs across multiple LLM providers
