Senior Software Engineer, AI Platform
Build core AI platform infrastructure at Harvey including model routing, context management, agent architecture, and shared evaluation frameworks that power all agentic legal AI products. Requires 5+ years backend experience with 1+ year in AI/ML, production multi-model systems, and platform-building track record.
About the job
What You'll Do
- 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.
Requirements
- 5+ years of experience building backend systems, with at least 1+ year focused on AI/ML engineering (Staff candidates will typically have 8+ years and a track record of technical leadership across teams).
- 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.
- Track record of building internal platforms, SDKs, or shared infrastructure that other engineering teams actually adopted.
- 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.
- Bias toward full ownership: navigate ambiguity well and don’t wait for a roadmap to start solving problems.
Nice-to-Haves
- Experience building evaluation frameworks.
- Working with agent/function-calling architectures.
- Familiarity with legal or other high-stakes professional services domains.
- Time at early-stage or hyper-growth startups where the underlying technology changes regularly.
