Engineering Manager ChatGPT Infra

Applied AI Engineering - London, UK

We’re looking for an experienced Engineering Manager to found and lead the ChatGPT Infrastructure team in London.

You’ll lead a small, talent-dense, high-impact team building the core runtime primitives and infrastructure that underpin how new ChatGPT experiences are built and scaled.

This is a high-ownership, 0→1 leadership role blending hands‑on technical leadership, startup‑style problem solving, and founding‑team building.

You’ll operate with a high degree of autonomy, working closely with product and research teams to design and build critical, load-bearing infrastructure components, while establishing the engineering culture and high‑trust environment that will come to define our London presence.

• Build and lead a small, talent-dense team responsible for foundational runtime systems powering ChatGPT.

• Drive the development of core infrastructure primitives that product engineers rely on to build new ChatGPT experiences (e.g., runtime frameworks, service integration patterns, and extensibility mechanisms within the ChatGPT runtime).

• Define and evolve the technical architecture of the ChatGPT runtime
  , unlocking new feature capabilities as part of our next phase of rapid growth.

• Work closely with product and research teams to ensure infrastructure enables rapid product development while maintaining strong reliability and operational discipline
  .

• Own the reliability of the systems your team builds
  —participating in incident response, supporting deployments, and helping evolve our operational model toward a follow-the-sun global infrastructure team.

• Hire and develop the early London team, helping establish the technical bar, culture, and operating model that will define our London engineering presence.

• Serve as a technical leader and connector between the London office and the broader global ChatGPT infrastructure organization.

• 7+ years of hands‑on software engineering experience, ideally building large‑scale distributed systems, developer platforms, or infrastructure products
  .

• Experience building and leading high‑caliber engineering teams
  , particularly in startup or early‑stage initiatives within larger companies.

• Proven ability to create a high‑trust, high‑agency culture where strong engineers can move quickly, take ownership, and operate effectively in ambiguous environments.

• Strong judgment in hiring and talent development
  , with a track record of building small, high‑performing teams and maintaining a high technical bar.

• Track record of remaining deeply technical as a leader
  , contributing to architecture and design decisions while enabling others to do their best work.

• Experience operating in 0→1 or high‑ambiguity environments
  , where teams are defining problems and building systems from scratch.

• Experience running production systems in cloud environments (e.g., AWS, GCP, Azure).

• Based in or willing to relocate to London.
