Artificial Intelligence OpenAI Speech Recognition Large Language Models Backend Front End Software Development Model Inference Data Pipelines

Job description

This is a full-time onsite position. You will work five days a week from our client’s office in San Francisco, collaborating in person with PMs, designers, and the GTM team to ship fast and stay close to the work.

This is a deeply technical role that blends ML, product thinking, and engineering. You will build and own production services that rely on LLMs and speech models.

What you’ll do

  • Develop and own end-to-end AI applications across a range of workflows, from copilots to automation tooling and beyond.
  • Improve our client’s LLM-powered platform, used daily by thousands of users.
  • Build and optimize inference pipelines and real-time speech recognition systems.
  • Collaborate closely with PMs, designers, and GTM teams to iterate rapidly and launch high-impact features.

Requirements

  • 3+ years building production AI systems, ideally in fast-moving environments or as a founder.
  • Extensive experience with LLM inference (OpenAI, Anthropic, Llama, etc.).
  • Strong product sense.
  • Comfortable working across the stack (frontend, backend, etc.) to get features shipped.
  • Obsessed with speed, ownership, and getting real user feedback.

This is a remote position, although Bay Area residents are encouraged to work from the client’s SF office.

Nice to Haves

  • Experience with ASR systems (e.g. Whisper).

Seniority

2 to 6 years of experience as a software engineer, with AI and LLM-focused product work.

Work experience

  • Must have built complex AI applications end-to-end (LLM inference work, agent products, etc.).
  • Experience in a fast-moving startup or as a founder.

Education

CS undergraduate degree from a four-year university.

Hard skills

  • Able to work across the stack (frontend, backend, infra) to problem solve and ship features.
  • Applied-AI literacy. Can reason about evals, statistics, and the non-determinism of LLM systems.
  • Familiarity with SOC-2 or sensitive data pipelines.

Soft skills

Obsessed with speed, ownership, and getting real user feedback.

Traits to avoid

Lack of progression in role after 2 to 3 years.
