Your role :
As a Software Engineer Java in the Mirakl Labs product teams, your main mission is to design, develop and deploy new business features proposed by the Product Manager. On a daily basis, you will be implementing these new features across all layers of our applications, from interfaces (UI or REST API) through the business layer to the creation of database schemas and scripts. As part of a team with total ownership over the products it develops, you are a key player in ensuring both the business consistency of the product and its technical stability.
The position is a permanent contract, based in Paris, with up to 1 day of remote work per week.
95% of our tech teams are based in France and 99% speak French.
Day-to-day activities:
- Build, test, and ship to production through continuous delivery
- Harness AI-powered tools like Claude Code, Codex, and Cursor to move faster
- Join design sessions alongside a team of 5 developers, the Product Manager, and UX/UI designers
- Shape technical decisions that drive the product forward
- Sharpen code quality through reviews and pair programming
- Own what you build — monitor and debug production issues end to end
- Take part in Stand-ups, Sprint Reviews, and retrospectives
- Help define the next quarter's labs roadmap
- Drive continuous improvement in how the team develops software
- Track the real-world impact of your features: business cycles, adoption, usage
Our tech stack:
Java 21 (with planned migration to 25), Spring Boot, Kafka, React/Redux, PostgreSQL, Elasticsearch, Go, Docker, Kubernetes, AWS, Google Cloud
You'll love this job if :
- You have at least 5 years of experience with Java and Spring
- You are genuinely curious (and pragmatic) about AI, and you believe it's already reshaping how developers work
- You are eager to work on web-scale challenges and distributed architectures
- You care deeply about clean, well-crafted code
- You want a real voice in technical decisions, not just a seat at the table
- You thrive in fast-paced, demanding environments where you grow every week
- You're hungry to learn and sharpen your craft
- You're fluent in French and comfortable working in professional English
