Platform Engineer (Developer Infrastructure)

San Francisco

About World Labs:

We build foundational world models that can perceive, generate, reason, and interact with the 3D world — unlocking AI's full potential through spatial intelligence by transforming seeing into doing, perceiving into reasoning, and imagining into creating. 

We believe spatial intelligence will unlock new forms of storytelling, creativity, design, simulation, and immersive experiences across both virtual and physical worlds.

We bring together a world-class team, united by a shared curiosity, passion, and deep backgrounds in technology — from AI research to systems engineering to product design — creating a tight feedback loop between our cutting-edge research and products that empower our users.


Role Overview

We are looking for a Staff Platform Engineer to own Developer Infrastructure at World Labs.

This is a high impact systems role focused on build systems, testing infrastructure, and release and rollout pipelines, the critical path that determines how code moves from local development to production.

You will define and operate the systems that make our engineering organization fast, reliable, and scalable, in an environment where both the codebase and workloads are evolving quickly.

You will be responsible for the architecture and operation of the systems that power developer velocity and production safety, making foundational decisions around build performance, dependency structure, test execution, and release reliability.

This role is about turning complex, failure prone workflows into systems that are fast, correct, and reproducible, and setting the technical direction for how we build and ship software.

This is a hands on role. You will design, build, and operate these systems directly.

What You Will Do:

  • Own the design and evolution of the build, test, and release systems that power the platform.
  • Define architecture for a Bazel based monorepo, including performance, caching, and dependency graph scalability.
  • Improve build performance and correctness, including incremental builds, caching strategies, and graph optimization.
  • Design and operate test infrastructure, focusing on reliability, isolation, and signal quality.
  • Build and improve release and rollout systems, including deployment pipelines, canarying, and rollback.
  • Improve end to end developer velocity, from local iteration to production deployment.
  • Debug and resolve complex issues across the pipeline, including build failures, dependency issues, test flakiness, and release regressions.
  • Establish standards for reproducibility, observability, and operability across build and release systems.
  • Identify and eliminate systemic failure modes across the development lifecycle.
  • Contribute broadly across infrastructure and reliability work when needed.
  • Mentor engineers and raise the bar for system design and technical decision making.

Key Qualifications:

  • 10 or more years of experience building and operating production systems at scale, with ownership of critical infrastructure.
  • Strong experience with build systems and dependency graphs such as Bazel, Buck, Pants, or similar, or the ability to quickly ramp on Bazel in a large monorepo environment.
  • Experience designing and improving build, test, and release pipelines, with a focus on performance, correctness, and reproducibility.
  • Strong systems understanding of how code moves from source to build to test to production.
  • Hands on experience debugging complex system issues, including build failures, dependency issues, test flakiness, and release regressions.
  • Experience owning systems with strict reliability and performance requirements.
  • Strong proficiency in at least one of Python, Go, or Rust, and comfort working across languages in a polyglot codebase.
  • Proven ability to define architecture and drive technical decisions end to end.
  • Strong judgment in balancing developer velocity, system complexity, and reliability.
  • Ability to operate effectively in ambiguous, fast moving environments with high ownership.
  • You have worked on systems where build performance, correctness, and reproducibility were first order concerns, not afterthoughts.

Preferred Qualifications:

  • Deep experience with Bazel at scale, including remote caching, remote execution, and build graph optimization.
  • Experience designing hermetic and reproducible build systems.
  • Experience improving test infrastructure at scale, including eliminating flakiness and improving signal quality.
  • Experience building or operating release and rollout systems, including canarying, staged rollouts, and rollback mechanisms.
  • Experience instrumenting systems for observability and debugging of build, test, and release pipelines.
  • Experience in early stage or high growth environments.

Who You Are:

  • Fearless Innovator: We need people who thrive on challenges and aren't afraid to tackle the impossible.
  • Resilient Builder: Impacting Large World Models isn't a sprint; it's a marathon with hurdles. We're looking for builders who can weather the storms of groundbreaking research and come out stronger.
  • Mission-Driven Mindset: Everything we do is in service of creating the best spatially intelligent AI systems, and using them to empower people.
  • Collaborative Spirit: We're building something bigger than any one person. We need team players who can harness the power of collective intelligence.

We're hiring the brightest minds from around the globe to bring diverse perspectives to our cutting-edge work. If you're ready to work on technology that will reshape how machines perceive and interact with the world, World Labs is your launchpad.

Join us, and let's make history together.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
