Role Details

As Lead Site Reliability Engineer, you'll provide technical and people leadership for the SRE team. You'll be responsible for the team's day-to-day operation, technical direction and engineering delivery, whilst working closely with the Director of Global Cloud Infrastructure to execute the wider platform strategy.

Reporting to the Director of Global Cloud Infrastructure, you'll take ownership of the day-to-day leadership and operation of the Site Reliability Engineering team. Working in close partnership with the Director, you'll translate strategic objectives into operational delivery, ensuring the team consistently delivers a resilient, secure and highly available cloud platform.

You'll work closely with Platform Engineering, Software Engineering, Product, Security and Client Operations teams to improve platform reliability through automation, engineering excellence and operational best practices.

You'll also play a key role in shaping the future of AI-assisted operations at ZILO, identifying opportunities to use AI to improve reliability engineering, incident response, automation and engineering productivity.

This is a hands-on engineering leadership role where approximately 70% of your time will be spent working alongside the team as a Site Reliability Engineer, designing solutions, improving automation and supporting production platforms. The remaining 30% will focus on leading the team, including coaching and mentoring engineers, managing performance, workload planning, holidays, on-call rotas and career development. You'll be expected to lead from the front, setting the technical standard through your own engineering contributions.

This role is not suited to candidates looking to move away from hands-on engineering into full-time management. We're looking for someone who enjoys leading people whilst remaining an active Site Reliability Engineer, spending the majority of their time solving technical challenges alongside the team.
