Chief of Staff

San Francisco, CAFull-time · On-siteOpen

You will work directly with the founders as a force multiplier: owning the things that fall between functions, running the operating cadence, and turning ambiguity into a plan. This is a high-trust, high-ownership role for an operator who wants to see the whole company and move it forward, not manage a single lane.

About ATBF Labs

ATBF Labs builds the inference engine for production AI. Every token a model serves in production runs through an inference stack, and that stack decides the latency, the cost, and the reliability of the product sitting on top of it. We build ours from first principles: custom GPU kernels, a purpose-built runtime, and a distributed serving layer that holds its tail latency under real load. We are a small team with a high bar, shipping to production from day one.

What you'll do

Key responsibilities

  • Run the company operating cadence: planning, goals, metrics, and the meetings that keep them honest.
  • Own cross-functional projects end to end, from a fuzzy problem to a shipped outcome.
  • Prepare board materials, fundraising narratives, and internal communications with the founders.
  • Build the early operational backbone: hiring process, vendors, finance ops, and tooling.
  • Sit in on the hard decisions, surface the data, and make sure the follow-through happens.
  • Be the connective tissue between engineering, go-to-market, and the founders.
Minimum qualifications
  • 5+ years in a high-velocity environment: operating, consulting, banking, or an early startup.
  • A track record of owning ambiguous, cross-functional work and finishing it.
  • Sharp written and verbal communication; you can write the memo and run the room.
  • Comfort with numbers: you can build the model and read the dashboard.
Preferred qualifications
  • Experience at an early-stage startup, ideally in AI infrastructure or deep tech.
  • Exposure to fundraising, board management, or strategic finance.
  • Enough technical fluency to hold a real conversation with the engine team.
  • A bias for action and a high tolerance for context-switching.
Compensation
$180,000 – $240,000 + equity

Base salary plus meaningful equity. The range is a guideline; final numbers reflect experience, skills, and location. Full health, dental, and vision coverage included.

Why ATBF Labs

Solve hard problems

Inference is a systems problem from the kernel up. You will work on the parts that decide whether a model is usable in production: latency, throughput, and cost.

Own the whole stack

Small team, large surface area. You will have real ownership across kernels, runtime, and serving, and your work ships to customers, not a backlog.

Measure everything

We make decisions on numbers, not vibes. Every change is benchmarked, every regression is caught, and the survey point marks exactly where we are.

Learn from the best

Work alongside people who have built and operated inference at scale, and who care more about a clean result than a clever one.
