You’ll leverage your engineering expertise to design and deliver resilient platforms, improve observability, automate operations, and guide squads in applying SRE principles effectively.
Working closely with Principal Engineers, Squad Leads, and cross-functional teams, you’ll embed a culture of continuous improvement, proactive incident management, and operational excellence.
As a senior team member, you will also mentor engineers, contribute to engineering strategy, and help define best practices across the tribe.
Main Duties

- Provide mentoring and guidance to junior and mid-level engineers.
- Collaborate with Principal Engineers and Squad Leads to align engineering work with wider platform goals.
- Help shape and implement the long-term technical strategy for reliability and scalability.
Implementation & Delivery
- Design and implement scalable, secure, and highly available systems on cloud platforms (Azure/GCP).
- Build and maintain monitoring and alerting solutions to ensure observability and proactive incident response.
- Contribute to CI/CD pipeline design, infrastructure as code, and deployment automation.
- Lead incident management activities, including post-incident reviews and improvement plans.
- Develop automation and tooling to reduce toil and improve delivery consistency.
- Document technical designs, solutions, and operational procedures to support collaboration and sustainability.
Technical Excellence & Best Practices
- Champion and embed SRE principles, including SLOs, SLIs, and error budgets.
- Actively contribute to peer reviews and encourage a culture of continuous feedback.
- Drive engineering maturity through shared standards, tooling, and modernisation efforts.
- Raise and track technical debt, driving its resolution across the platform estate.
- Stay up to date with evolving infrastructure, cloud, and DevSecOps practices and recommend relevant innovations.
