Job summary

OMP Belgium is seeking a Lead Software Engineer to design, build, and deliver high-performance, scalable software systems. This is a hands-on role focusing on production-ready solutions, code, and mentorship.

You will own delivery end-to-end, maintain code quality, and drive architectural excellence across components. The position emphasizes observability, AI-based testing, and proactive issue detection in production.

Responsibilities

Designing and building scalable solutions with a strong focus on performance, maintainability, and cross-component integration.
Taking ownership of delivery from design to production, and living 'you build it, you run it', so your team owns what it ships and keeps it reliable in production.
Staying hands-on in the code while keeping delivery on track: unblocking the team, holding the bar on quality, and mentoring fellow engineers.
Challenging and refining requirements with product analysts to ensure clarity, feasibility, and delivery readiness.
Owning technical correctness, including performance and scalability.
You shift quality left and reimagine how QA is done, building AI-based testing frameworks that deliver strong automation and fast feedback so issues surface early. This covers the full range of testing: performance, load, spike, soak, and security testing.
Building observability into the software as a core principle, so your team can run it with confidence and catch issues before customers do.
