Location: San Jose, CA
Experience: 1–5 years
Team: Applied AI
We’re hiring an AI/ML Engineer to build production AI systems for technical users. This is an applied engineering role for someone who can take modern model capabilities and turn them into reliable systems that people actually use.
The core problems in this role are the same ones that matter in modern applied AI: getting the right context into the system, making tool use reliable, designing useful abstractions around skills and workflows, building evals that reflect real tasks, and iterating until the system is good enough to become part of a team’s daily workflow.
In practice, you might work on coding agents in terminal and IDE environments, verification and debug assistants, log-analysis systems tied to real product diagnostics, documentation and spec-comparison agents, or internal assistants that operate over company knowledge and engineering data. You will be expected to think end-to-end: prompt and context design, retrieval quality, tool interfaces, evals, failure modes, deployment, and ongoing improvement.
They have built more than demos. They have worked on systems where retrieval quality matters, where tool use can fail in subtle ways, where evaluation changes engineering decisions, and where product usefulness depends as much on system design as on model choice. They usually care about the details that separate a clever prototype from a dependable system.
The team’s direction is very concrete: enterprise search, coding agents, workspace automation, customized skills, and agentic applications for specific engineering problems, all measured against real usage and outcomes. This role sits directly in that path. If you want to build applied AI systems that are ambitious but grounded in real workflows, technical users, and fast feedback loops, this is that job.
The base pay range for this position is $140,000 - $165,000
