What are we looking for?

We are seeking a Principal Architect to join our Developer Platform organization. In this role, you'll be our Developer Platform's technical leader and visionary, responsible for designing and driving our "North Star" architecture. You will be a hands-on leader who can translate complex concepts into a clear technical strategy, ensuring a coherent and consistent platform for all S1 engineers.

What will you do?

• Architect the Future: Design and drive the end-to-end architecture of our Developer Platform. This includes seamlessly integrating with key organisations like Quality Assurance (including Performance), Security, IT, and SRE.

• Provide Technical Leadership: Serve as a go-to technical advisor for our most senior colleagues. You'll advise on approaches and review solutions, going as deep as necessary to ensure a coherent platform.
• Be a Bridge Builder: Act as a critical link between the platform's underlying infrastructure and the developers who use it. You'll focus on creating clear standards and ensuring an excellent developer experience.
• Stay Hands-On: While your main focus is architecture, we value strong engineering skills. You should be able to prototype your suggestions to bring ideas to life. We don't expect this on a daily basis, but the ability to do so will be a significant benefit.
