Technology

In short

At On, we believe technology should move as fast as a runner. We are building the foundation that allows our engineering organization to scale, innovate, and deliver value without friction.

We are looking for a Senior or Lead Software Engineer to join the Developer Experience (DevEx) team. In this hands-on IC role, you will help to build the platform that empowers dozens of technology teams to build, ship, and operate services effortlessly. You will be involved in building and architecting our "Golden Path," ensuring that speed, safety, and reliability are baked into every developer's workflow.

Your Mission

Help Engineer the Golden Path: Design and implement highly automated CI/CD pipelines (GitHub Actions) and common templating (Typescript/Node) systems that allow a developer to go from "idea" to "production-ready service" in minutes.
GraphQL Infrastructure: Act as a contributor to our central Apollo GraphQL API Gateway. You will manage the supergraph composition, runtime stability, and schema governance standards to ensure a consistent contract for all consumers.
Help Build the Internal Developer Platform (IDP):Help to Develop our Cloud Abstraction Layer and Developer Portal. This includes building self-service tools, CLIs, and service catalogs that reduce cognitive load for engineers.
SRE & Observability: Integrate "secure-by-default" practices and robust observability into the platform. You’ll build dashboards (NewRelic) and monitoring patterns that provide teams with deep insights into their service health.
Technical Excellence & Advocacy: Write high-quality documentation, and advocate for DevEx best practices across the organization.
Friction Reduction: Actively hunt for bottlenecks in the software development lifecycle. Whether it's a slow build or a complex deployment process, you will be involved in fixing it.

Your story

Product Thinking: You treat internal developers as your customers. You listen to their pain points and iterate on the platform based on real-world feedback.
Infrastructure as Code: You are comfortable with Terraform and Kubernetes (GCP experience is a plus), treating infrastructure with the same rigor as application code.
Automation Mindset: You are passionate about CI/CD (GitHub Actions) and building developer tooling (CLIs, SDKs, or Portals).
AI-Augmented Engineering Workflows: You leverage (or have an active interest in) the latest agentic coding tools to 10x your productivity, blending deep technical principles with AI-assisted workflows. As a power user of AI, you orchestrate complex builds and bypass boilerplate to deliver robust, scalable code at pace, ensuring our TypeScript/Node.js environment remains lean and efficient (other tech-stacks are acceptable).
Architectural API Design: Tangible experience in crafting robust API contracts with a focus on GraphQL Federation; familiarity with the Apollo tech stack is highly regarded.
Data-Driven: You understand DORA metrics and DevEx signals, using them to measure the success of the tools you build.

What Success Looks Like:

Velocity: A measurable reduction in lead time for new services reaching production.
Autonomy: Product teams can provision infrastructure and deploy APIs independently using your self-service tools.
Stability: High adoption of standardised "Golden Path" templates, leading to fewer production incidents and faster MTTR.
Satisfaction: High internal Developer Satisfaction (DevEx) scores and positive feedback on the tooling you maintain.
Team Spirit: You thrive in a high-performing "sports team" culture, contributing to the power of the whole through consistent teamwork and earned leadership.

About the Team

The Developer Experience team serves as the bridge between infrastructure and product. We don't just measure "uptime"; we measure "time to value." As a Staff Engineer on this team, you will be at the heart of our engineering culture, defining the standard for how software is built and delivered at On.londlo

London

Home to nearly 3000 parks, a population speaking more than 300 languages, and a vibrant art and music scene, London is one of the world’s most loved cities for good reason.

What we offer

On is a place that is centered around growth and progress. We offer an environment designed to give people the tools to develop holistically – to stay active, to learn, explore and innovate. Our distinctive approach combines a supportive, team-oriented atmosphere, with access to personal self-care for both physical and mental well-being, so each person is led by purpose.

On is an Equal Opportunity Employer. We are committed to creating a work environment that is fair and inclusive, where all decisions related to recruitment, advancement, and retention are free of discrimination.

Build the better you

What to expect

We want to set everyone up for success, so here’s the lowdown on how we hire. Our process is a two-way street – bringing you into our culture, while helping us learn how you think.

Our full process can last about eight weeks from application to offer, because we care about getting it right. These steps explain how we usually do things.

Before you get started, feel free to consider if you want to work with us. Strange question? Well, we give people a lot of space to navigate their day-to-day and that style isn't for everyone. We want you to be passionate about what you do and be sure this is the right fit. Because when skills and passion combine – it creates that 'Wow' moment.

Step One

It starts with you...

You'll start by submitting your application to a specific role. We try to keep this step as simple as possible. We do get a lot of applications, but we review them all. If you're a good fit to the role, a recruiter will follow up with you directly. If you didn't receive a reply, or were unsuccessful this time around, we encourage you to look for other possible matches at On.

Step Two

Interview with a recruiter

What ignites your spirit? This is where we’ll start getting to know all about you and what makes you tick – and it’s your first chance to get a feel for our culture. Chatting with a member of our talent team, you’ll learn more about On and how we work. We’ll learn about what motivates you and what you could bring to the team.

Step Three

Interview with a hiring manager

Ready to dig into the details? This second interview will be held with your future manager and will focus on the specifics of the job. Together you’ll delve into your unique skills and experiences and how they could be relevant at On. It's also a time to assess how you might feel working side-by-side. Bring any questions you have about the job, the team or anything else you might like to know – this is an open forum.

Step Four

The Case Study

What's your style? This task will help us understand how you think, face a challenge and give insight into your novel ideas. Designed to give everyone their best shot, your case study is based on something you might typically experience on the job. This is your chance to show us what you’ve got. So express yourself. Be you.

Step Five

The Experience Day

Your first taste of the Oniverse. This is a time to meet some of the people you'll be working closest with. In person or virtually, you'll get a feel for the day-to-day at On and the people who make it happen. You'll chat with a few potential teammates - the conversations will be as equally driven by the role and your experience as by our values. We believe how you do things is just as important as what you do.

Step Six

The Result

Are we a good fit? We’ll get together internally to share our feedback and decide if we’re a match. We know that job searching is a big time investment, so it’s not a decision we take lightly. It’s also time for you to reflect on the experience – are we the right place for you? No matter the outcome, we’ll give you meaningful feedback.
