About the job
At Harvey, the future of professional services is being written today — and we’re just getting started. The AI Platform team builds the foundation that every product and agent team at Harvey builds upon. This team is early and there’s a lot to build: model routing, agent architecture, context management, evals. Your work here sets the ceiling for what Harvey’s AI can do.
Responsibilities
Design and build abstractions and platform-level systems that improve all of Harvey’s agentic products.
Own infrastructure for model integration, routing, and evaluation that helps Harvey choose and deploy the right foundation model for any given context.
Build evaluation frameworks and tooling that let every team across Harvey iterate on AI quality effectively.
Partner closely with product engineering teams, PMs, and design to launch cutting-edge AI products.
Evaluate, prototype, and integrate the latest advancements in AI and agentic systems as they emerge.
Qualifications
Minimum
5+ years of experience building backend systems, with at least 1+ year focused on AI/ML engineering.
Experience building and shipping multi-model or multi-provider AI systems in production.
Familiarity with context management, session state, or memory systems in AI or distributed systems.
A track record of building internal platforms, SDKs, or shared infrastructure that other engineering teams actually adopted - and an understanding of why developer experience matters as much as raw capability.
Strong judgment about abstractions. Opinionated about good design but pragmatic about shipping incrementally.
Excitement about agentic AI and the infrastructure challenges of making autonomous systems reliable when the stakes are real.
A bias toward full ownership: you navigate ambiguity well and don’t wait for a roadmap to start solving problems.
Preferred
Bonus: experience building evaluation frameworks, working with agent/function-calling architectures, familiarity with legal or other high-stakes professional services domains, or time at early-stage or hyper-growth startups where the underlying technology changes regularly.
