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.

Recruit, onboard and mentor new team members as the team grows.
Foster a collaborative, accountable and high-performing engineering culture.

Production Operations

Own the reliability, availability and performance of ZILO's production platforms.
Work alongside Platform Engineering and Software Engineering teams to support, maintain and patch production environments.
Define, measure and continually improve Service Level Indicators (SLIs), Service Level Objectives (SLOs) and error budgets.
Drive continuous improvements to system resilience, fault tolerance and operational readiness.
Lead platform capacity planning and performance optimisation activities.

Incident Management

Lead the technical response to high-severity production incidents, providing calm and effective technical leadership during major outages.
Coordinate post-incident reviews and Root Cause Analysis (RCA), ensuring corrective and preventative actions are identified, prioritised and delivered.
Drive continuous improvement of incident management processes, reducing Mean Time to Detect (MTTD) and Mean Time to Recover (MTTR).

Automation & Platform Engineering

Eliminate operational toil through automation and engineering-led improvements.
Design, develop and maintain tooling that improves engineering productivity and operational efficiency.
Identify opportunities to simplify operational processes through automation and self-service capabilities.
Work with Platform Engineering to ensure the platform remains scalable, resilient and capable of supporting future business growth.
Identify opportunities to leverage AI to improve operational efficiency, automate repetitive tasks and enhance engineering productivity.
Develop and adopt AI-assisted tooling to support troubleshooting, platform operations and continuous improvement.
Champion the responsible adoption of AI across the engineering organisation.

Observability

Continuously improve monitoring, alerting and operational dashboards across the platform.
Enhance platform observability through effective use of metrics, logs and distributed tracing.
Design meaningful alerts that reduce noise and alert fatigue whilst improving the speed and accuracy of incident detection.
Promote a data-driven approach to platform reliability using telemetry and operational insights.

Operational Responsibilities

Participate as an active member of the SRE team, contributing to the day-to-day support and operation of production platforms.

Participate in the team's on-call rota, responding to production incidents when required.
Participate in a rotational UK shift pattern to provide operational coverage and close collaboration with UK engineering teams.
Support planned maintenance activities, production releases and out-of-hours changes where required.
Ensure the SRE team provides effective operational coverage across business-critical services.

Continuous Improvement

Promote a culture of continuous improvement, engineering excellence and operational ownership.
Collaborate with Development teams to embed reliability into the software development lifecycle.
Identify opportunities to improve platform stability, deployment processes and operational efficiency through engineering best practices.

Candidate Profile

The ideal candidate is a proven engineering leader who has successfully led an SRE team before. You're passionate about building highly reliable cloud platforms, enjoy solving complex distributed systems problems and believe the best leaders remain close to the technology.

You thrive in production environments, are comfortable leading major incidents, and enjoy mentoring engineers through example rather than hierarchy. You understand that reliability is built through automation, observability and engineering excellence—not manual processes—and you're motivated by helping both people and platforms perform at their best.

At ZILO, we believe AI is transforming software engineering. We're building an AI-native engineering organisation where engineers use AI as a force multiplier—not a replacement—to automate repetitive work, accelerate problem solving and focus on delivering greater value. We're looking for someone who shares that mindset and is excited to help shape the future of Site Reliability Engineering through the practical application of AI.
