About the Role
The Senior Platform Engineer will provide technical leadership in shaping, evolving, and scaling our clients' cloud platform. You will establish 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. This role operates across architecture, engineering, reliability, automation, and developer enablement, influencing 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 platform 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 technology choices; mentoring engineers and promoting strong platform engineering practices; and championing a culture of automation, ownership, continuous improvement, and operational excellence.

Join AND Digital and help close the world’s digital skills gap by working in a collaborative, ambitious, and fun environment that values wonder, sharing, and delight. Benefit from a blended working model, career development support, training budgets, and a safe, inclusive culture.
