About the Role
The Principal Platform Engineer will provide technical leadership in shaping, evolving, and scaling our clients' cloud platform. This role focuses on establishing robust, reusable platform capabilities and self-service solutions that enable engineering teams to deliver software faster, more reliably, and with a consistently high developer experience. Operating across architecture, engineering, reliability, automation, and developer enablement, you will influence technical strategy while remaining hands-on in the design and delivery of platform capabilities.

Key responsibilities include defining and evolving the technical strategy, architecture, and roadmap for an AWS cloud platform; designing and building scalable, secure, resilient, and reusable platform capabilities; developing self-service tooling and services to abstract operational complexity and improve developer productivity; driving automation across infrastructure, application delivery, operational processes, and platform management; establishing and promoting platform standards, engineering patterns, and best practices; improving reliability, scalability, performance, observability, and operational efficiency; identifying opportunities to reduce engineering friction and accelerate software delivery; establishing engineering principles and guardrails to maintain security, reliability, and governance; leading technically complex platform initiatives from discovery through implementation and operational adoption; influencing engineering teams and senior stakeholders on platform strategy and architectural decisions; mentoring engineers to raise capability and promote strong platform engineering practices; and championing a culture of automation, ownership, continuous improvement, and operational excellence.
