Engineering Manager ChatGPT Infra

About the Role

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.

You will

• 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.

Qualifications

• 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.
