Job description

Senior Software Engineer

Rotterdam - Full-time

You’ve shipped systems that real operations depend on. You care about the problem more than the framework, and you can explain a hard trade-off to a terminal operator and a CTO in the same afternoon.

You’ll join small senior teams working on high-stakes digital products in ports, healthcare, logistics and energy.

About You

• Several years building production software end-to-end
• Comfortable owning architecture decisions and explaining them clearly
• Curious about the domain — ports, hospitals, grids — not only the stack
• Happy in a small team without heavy process

Perks

• Senior peers, no bench, real ownership
• Rotterdam studio + flexible remote days
• Work that shows up in the physical world
• Competitive salary and room to grow sideways as well as up

Your skills

• TypeScript
• System design
• APIs
• Cloud
• Product thinking

About Us

We’re a Rotterdam team of experienced engineers, designers and strategists. We build digital products and strategies for organisations where the work is real: ports, hospitals, supply chains, energy grids. Sometimes we bring the team, sometimes we join one where our expertise makes the difference. Either way, we stay close to the real work. Small teams, high stakes, honest conversations. If you’d rather prove things than present them, you’ll fit right in.
