AI Agent Engineer

Why Benchmark Sports

Benchmark Sports is redefining how golf is learned through real-time simulation and AI coaching. We're profitable, moving fast, and scaling globally. Joining now means owning core systems used by millions of athletes. Shipping product that changes how people train.

The Culture

High ownership, touching all elements of the product full stack, owning business outcomes on a small lean team of highly technical people. We have a high talent bar and only hire people capable of working full stack and having a clear understanding of the product mission.

In office in Irvine. Work 6 days a week.

What You'll Work On

• Build AI coaching agents that give athletes real-time feedback on their swing

• Own the LLM stack: prompts, tool use, RAG, context management

• Ship multi-turn coaching conversations that hold context across sessions

• Build evaluation and grounding systems that catch hallucinations against real swing data

• Get response latency low enough for live coaching

Core Expectations

• Strong ML fundamentals

• Up to date with latest agentic coding workflows

• Full stack experience with good taste for UI/UX

• Worked on either cutting edge implementations of LLMs or shipped LLM products used by real users

Who Thrives Here

Young, ambitious builders with a blank-slate mindset. Founder energy or campus incubator DNA. Someone who has shipped things end-to-end and owns the outcome. Strong preference for candidates from top technical environments (Stanford, Berkeley, Cal Poly, CMU), but we'll hire the best builder regardless of pedigree. If you need a roadmap to do your best work, this role will be a bad fit.
