SRE Tech Lead

Location: Remote

Salary: £80,000 - £90,000

About us

At Arbor, we’re on a mission to transform the way schools work for the better. 

We believe in a future of work in schools where being challenged doesn’t mean being burnt out and overworked. Where data guides progress without overwhelming staff. And where everyone working in a school is reminded why they got into education every day. 

Our MIS and school management tools are already making a difference in over 7,000 schools and trusts. Giving time and power back to staff, turning data into clear, actionable insights, and supporting happier working days. 

At the heart of our brand is a recognition that the challenges schools face today aren’t just about efficiency, outputs and productivity - but about creating happier working lives for the people who drive education everyday: the staff. We want to make schools more joyful places to work, as well as learn. 

About the role

We are looking for an experienced and collaborative Site Reliability Technical Lead to join our Site Reliability team and take ownership of system and solution design to ensure our products are robust, scalable, and secure. The remit and focus of the role is to blend deep technical expertise with leadership, requiring you to mentor and coach engineers, embed a culture of quality and reliability, and guide the team in making sound technical decisions. It’s a broad and exciting role, so we’re looking for someone up for a challenge - if you’re highly technical and a good communicator, this is the role for you.

• Planning and Delivery: Lead technical estimation and feasibility assessments, ensuring plans are realistic and aligned with team capacity. Contribute to structured release planning and support post-release reviews.
• Mentorship and Coaching: Mentor and coach engineers through constructive feedback, knowledge sharing, and motivation. Foster alignment and help the team galvanise around technical solutions and goals.
• Collaboration: Work closely with Product Managers, Engineering Managers, and other engineers to align technical direction with product strategy. Communicate complex technical concepts clearly to both technical and non-technical stakeholders.

About you

• Programming: Strong skills in Python, Go, or a similar language for automation and tooling.
• Observability: Deep experience with monitoring and observability platforms (e.g., DataDog, Prometheus, or equivalent), plus incident/problem management.
• System Design: Expert understanding of distributed systems, microservices, and resilience patterns.
• Containerisation: Hands-on experience with containerization and orchestration technologies (Docker, Kubernetes, ECS).
• CI/CD: Practical experience with building and maintaining CI/CD pipelines for automated deployments.
• Leadership: Demonstrated ability in mentoring and supporting the growth of fellow engineers.
