ENTER THE GAME🎮

Betclic runs one of Europe’s largest sports betting platforms. Hundreds of engineers across fifteen tribes ship to production every day, and peak traffic doesn’t wait for anyone.

Our Developer Experience team builds the platform they all ship on: CI/CD, runners, the internal developer portal, and the practices and guardrails that come with them. We’re a small team with a large surface. That means real ownership rather than tickets, and it’s why we’re looking for senior engineers who can take a product and run with it. When we do our job well, a developer goes from idea to production without ever thinking about us.

YOUR ROLE WITHIN BETCLIC 🔥

You’ll own internal products used by every engineer in the company. Concretely:

• Build and run the CI/CD platform. GitHub Actions, self-hosted runners, elastic capacity that scales with demand without burning the budget.

• Write the code. Integration components around GitHub, Jira, monitoring, code analysis. We build, we don’t just configure.

• Make security invisible. Supply chain, secrets, scanning, quality gates, all in the default path, so nobody has to think about them.

• Shape how we use AI. Agentic workflows are in production here. We test, validate and iterate fast in a space that changes every month. What works gets turned into practice for everyone.

• Work directly with the tribes. You’ll know the teams you build for, hear where they lose time, and let that shape what you build next.

• Measure everything. We measure delivery across the whole company, so you can tell whether your work actually made teams faster.

• Practise what we recommend. TDD, automated tests, continuous deployment, observability. On our own products first.

Technical environment

• Cloud & IaC: AWS, Azure, Terraform, Kubernetes

• CI/CD: GitHub Actions, Dagger, SonarQube, Artifactory

• AI tooling: GitHub agentic workflows, AI coding assistants

• Developer portal: Backstage

• Security: Wiz, DefectDojo, Xray, Curation

• Languages: Python, Rust, Go

• Runtime: Docker, Lambda, Fargate, Container Apps, Serverless

• Observability: Datadog

• Practices: everything-as-code, TDD, trunk-based development, continuous deployment, DORA

WHO ARE WE LOOKING FOR? 🔍

We’re looking for curious, kind people who like making other engineers faster. This is a senior role.

This job is for you if:

• You have several years of experience building and running production infrastructure, and you’ve been the person others come to when it breaks

• You know CI/CD pipelines and cloud infrastructure well, and you code comfortably in at least one language

• You’ve worked on developer tooling or platform engineering, or you’ve been the person in a product team who ended up owning the pipelines because you cared

• You learn more from watching someone struggle with your tool than from a ticket describing it

• You consider a tool finished when people use it, not when it ships, which means convincing them, not just building it

• You already work with AI: coding assistants, agents, automation. You know what it speeds up and what it quietly breaks

• You want to shape how a whole company uses it, not just your own workflow

• Professional English is required
