Hands-On Lead C++ Engineer: Build, Run, Scale

OMP Belgium; Antwerpen; On-site; EUR 70,000 - 100,000; Full time

Job summary

OMP Belgium seeks a lead C++ software engineer to design, build, and deliver high-performance, scalable software systems. This is a hands-on role: you spend your time in the code, combining deep technical expertise with mentorship as you build and run production-ready solutions.

You will own delivery from design to production, stay hands-on in the code, unblock the team, maintain quality, and collaborate with product analysts to ensure clear, feasible requirements.

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.
