We're more integrated and product led in our tech teams than ever before: learning, changing, and adapting constantly, with millions of people benefiting from your work every single day.

You’ll be joining the M&S Platform team as a Software Engineering Manager. Our mission is to streamline development at M&S for 1000+ engineers and 30+ applications - covering both our customer-facing and colleague-facing applications.

You will manage the team building the SRE function. You will support the team and help direct the technical vision for how we will build reusable pipelines, tooling, build plugins and frameworks that our many apps will harness to boost the developer experience, while contributing code every step of the way.

• Line management of supporting Staff and Senior Engineers, as well as driving recruitment and retention within the team.
• Act as custodian of OKR's within your hub.
• Supports our engineering communities to drive bar raising and strategic alignment, by creating the space and time within teams for the agenda of these communities to be progressed efficiently.
• When vendors are involved, the SEM is positioned as the key technical partner. They own it as a vital part of their platform with the same level of reliability and satisfaction as the in-house capabilities they build and run.

Who You Are

• Previous polyglot hands-on senior software engineer
• Excellent knowledge in SRE concepts and trade-offs
• Extensive background in software engineering with several years' experience in a variety of systems and technologies
• Experience building and leading teams of highly skilled, senior software engineers that deliver high-quality software.

• Strong understanding of testing strategies and reliability engineering
• Excellent people management, interpersonal, analytical, and problem-solving skills
• Ability to lead and line manage senior engineers and technical partners to a desired outcome, without prescribing it.
• Excellent communication skills, both written and spoken and able to adjust for different, including non-technical audiences.
