The ChallengeTired of endless meetings where nothing gets decided? Frustrated by corporate bureaucracy that slows down actual building? Ready to work on technology that actually moves the needle?We're building the Adyen of the labor market. Just like Adyen revolutionized payments, we're transforming how people get contracted and paid in the Netherlands. It's a complex problem space - think CAO's, temporary employment regulations, payroll rules, and constantly changing legislation - that desperately needs a modern, scalable solution.This isn't just another SaaS product. This is infrastructure for the future of work.Who We AreMaqqie is one of the fastest-growing tech companies in the Netherlands. We're in scale-up mode, which means we're past the chaos of early startup life but still small enough that your work directly impacts thousands of workers and hundreds of companies. No layers of management between your code and real impact.Our mission: create a digital labor market that works better for everyone. Currently, we handle contracting and payments for all employment types - from permanent employees to temporary workers and freelancers. The regulatory complexity is immense, which makes the technical challenge fascinating.What You'll Actually DoAs Senior Backend Engineer, you'll be:Architecting solutions that matter: Design and build scalable systems that handle the intricate logic of Dutch employment law. Think complex rule engines, automated compliance checks, and payment orchestration across multiple contract types.Leading technical direction: Act as technical lead on projects that shape our platform architecture. You'll collaborate with Product to define scope and milestones, but you'll own the technical decisions.Solving genuinely hard problems: Our domain is complex - CAO compliance, phase systems, benefit calculations, multi entity payroll. This isn't CRUD. You'll need to understand both the technical and business context deeply.Building for scale: Optimize performance, eliminate bottlenecks, and ensure our systems can handle rapid growth without breaking. We're building the payment engine for the entire labor market.Growing the team: Mentor junior engineers and help us hire the next wave of talent. Shape our engineering culture as we scale.You'll work in cross functional teams with Product and Operations. We're 15 engineers across 3 teams, reporting to Luc Klaassen, our Head of Engineering. Small enough to know everyone, big enough to tackle serious challenges.The Technical LandscapeOur stack:Languages: Kotlin/Java, TypeScript, VueInfrastructure: Google Cloud Platform, Kubernetes, DockerCI/CD: GitLab Pipelines, JenkinsDatabases: PostgreSQL, MySQLBuild tools: Gradle, MavenWe're continuously modernizing. Legacy exists, we're honest about that, but we're actively addressing technical debt while building new scalable modules. You'll have real influence on our architectural direction.
