Senior Software Engineer

Location: The Hague / Hybrid

Hey there! We’re CERRIX, a fast-growing B2B SaaS scale-up helping organizations manage their risk and compliance in a smarter, more collaborative way.

We’re on a big journey: turning a successful (but aging) single-tenant monolith into a modern, modular, multi-tenant platform that can power the next stage of our growth. And we need someone like you to help make it happen. 🚀

What you’ll be doing

• Build the future of our platform: work on a multi-year modernization journey that’ll define CERRIX for the next decades.
• Get your hands dirty in code and architecture: refactoring core services, introducing multi-tenancy, externalizing identity, and improving performance at scale.
• Work closely with product & platform teams: you won’t just build features, you’ll help shape how we build everything.
• Level up engineering practices: CI/CD pipelines, automated testing, event-driven patterns, security hardening… the works.
• Bring ideas, not just code: we love people who challenge assumptions, suggest better ways, and help the team grow.
• Collaborate with a small but ambitious team: we move fast, stay close, and keep things transparent.

Your toolkit

• Solid experience building and maintaining complex software systems in .NET.
• A good grasp of modern architectural patterns (modular monoliths, event-driven systems, microservices - or a real hunger to master them).
• Familiarity with CI/CD, automated testing, and cloud platforms (we’re on Microsoft Azure).
• A love for clean, well-structured code and a willingness to get deep into a legacy codebase to make it better.
• A pragmatic mindset: you know when to build big and when to keep it simple.

Bonus points

• Experience in a SaaS scale-up or modernization project.
• Experience with identity management, multi-tenant architectures, or infrastructure as code.
• Experience with Domain Driven Design (DDD): not just knowing the theory, but having actually done it: helping teams apply it in real life, guiding architecture decisions, and getting the right people from across the company involved.
• Dutch-speaking skills.
• Familiarity with governance, risk & compliance software.

Why you’ll love working here

• We’re growing fast, which means lots of opportunities to make an impact.
• You’ll work with a team that values openness, curiosity, and good humor.
• No rigid hierarchies: we like people who take initiative.
• You’ll be part of a true SaaS product company.
• Competitive salary and benefits to support your well-being and growth:
  • Ergonomics Voucher – Upgrade your home office with a voucher to improve comfort and productivity.
  • Quarterly Mental Health Days – Take one fully paid day off each quarter to rest and recharge.
  • Learning & Development Budget – Receive an annual personal budget of €500+ for professional development.
  • Flexible Work Location – Work from the office two days per week, with the option for occasional "workations" from inspiring locations.
