Job summary

Capital on Tap is seeking a Senior Engineer for the Developer Enablement team in London. You will help define the developer platform, set direction, and work with product engineers in the office to understand friction and drive improvements.

You’ll lead the design of golden paths, enable self-service provisioning, and push progressive delivery with Flux. A hands-on technologist who enjoys collaborating with teams will thrive here.

Qualifications

• Significant experience in platform engineering, DevOps or developer tooling.
• A track record of designing and rolling out golden paths, paved roads or self-service platforms, and getting teams to adopt them.
• Deep experience with CI/CD at scale (GitHub Actions, Azure DevOps, Octopus Deploy or similar).
• Strong hands-on Kubernetes and Docker experience, including setting standards for teams who deploy to it.
• Experience with GitOps and progressive delivery (Flux, Argo CD, Flagger or similar).
• Strong infrastructure and platform coding skills with Terraform.
• Proficiency in Go, C#, Python or PowerShell, with experience building tools that other developers use.
• A good understanding of how application teams build software, ideally with .NET experience.
• A strong product mindset: you talk to your users, measure outcomes and prioritise based on evidence.

Responsibilities

• Spend time in the office with product engineering teams, building relationships with developers and leads and understanding how they build, test and ship.
• Turn what you see on the ground into a clear developer experience roadmap, and agree priorities with engineering leads and Platform Engineering.
• Own the design of our application golden paths, and drive adoption across our services.
• Shape our Internal Developer Platform (IDP), so a new service can go from idea to production through self-service provisioning with standards built in.
• Drive progressive delivery with Flux, making releases safer, faster and more automated.
• Set the standards for how product teams use Kubernetes, including cluster conventions, RBAC, product engineering CRDs and developer tooling such as Headlamp and Mirrord.
• Define standards for configuration, variables and secrets, and build automated validation so they’re easy to follow.
• Lead service autodiscovery, dependency mapping and health check standards across the estate, working closely with SRE.
• Lead by example with AI, using it to speed up delivery and helping the team adopt it safely and effectively
• Have a data driven mindset, using it to measure developer experience and show impact.
• Mentor engineers in the team, review designs and code, and help build a culture that treats developers as customers.
• Write clear documentation and work directly with product engineers to understand their pain points and remove friction.
