Developer Enablement at Capital on Tap 🚀
Developer Enablement’s mission is to build golden paths from repo to production that are fast, safe and self-service. We look after the tooling, pipelines and Kubernetes experience our product engineers use every day, so they can spend their time shipping features instead of fighting infrastructure.

As a Senior Engineer you’ll help set the direction for the team from day one. You’ll shape what our developer platform looks like, decide where we invest first and take engineers with you on the journey. You can’t do that from a distance. You’ll spend real time in the office with our product teams, sitting alongside developers, and seeing the friction first-hand. What you learn there becomes the roadmap.

What You’ll Be Doing 🗃️

• 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 (e.g. lead time, deployment frequency, onboarding time, developer feedback) and use it to show impact and guide decisions.
• 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.

Our Values & Culture 🌞

• Just Pilot: We never settle for “good enough”. We pilot new ideas fast, ask questions to figure it out, and scale quickly.
• Why Not Today? Fast is as slow as we go - speed and simplicity gives us a competitive advantage.
• Be a Buddy: We tap in from day one to help the team, we do the right thing even if it’s hard.
• Owners and Dates: We don’t chase people. If you own a task and agree to a date, the expectation is that it gets done.
• Feedback: We want our employees to flourish, so we regularly provide direct and constructive feedback.

We’re Looking For 🔎

• Significant experience in platform engineering, DevOps or developer tooling, including building platforms or tooling that other engineers depend on.
• 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 tools such as Terraform.
• Someone who embraces AI as part of how they work, moves faster, automates repetitive stuff and focuses on the problems that matter, while knowing when to apply their own judgement.
• 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.
• Someone who enjoys being in the office and close to the people they support. You’d rather sit with a team for a morning than guess from a backlog.
• The ability to influence across teams and explain trade-offs clearly to engineers, leads and leadership.
• Experience mentoring engineers and raising the bar in a team.
