At a glance
- Work mode
- Remote · Netherlands
What you'll do
- Design and deliver high-quality, scalable solutions for complex features and system components
- Make informed architectural decisions that balance pragmatism with long-term vision
- Set the bar for technical craft through contributions and code reviews
- Own complex technical initiatives from design through production, breaking them into testable increments
- Define comprehensive testing strategies for complex features, championing quality within the team
- Debug and resolve complex issues across multiple components, improving system observability
- Apply security best practices throughout the development lifecycle
- Contribute to monitoring, alerting and system health improvements
- Mentor engineers with targeted technical guidance and feedback
- Support onboarding and enable a collaborative, knowledge-sharing environment
- Help shape delivery practices and improve team velocity through data-informed decisions
What we're looking for
- Deep backend engineering experience with complex, high-scale systems
- Modern PHP & architectural patterns: experience with hexagonal architecture, domain-driven design, or similar patterns that emphasize domain modeling over framework magic
- SQL & database design: comfort writing raw SQL (not just ORM abstractions) and working with complex relational schemas, particularly around time-sensitive data like scheduling, timesheets and payroll
- Legacy modernisation experience: gradually evolved mature systems rather than pursuing big-bang rewrites
- Monolith to services: experience breaking down monoliths with good judgment about when distribution solves real problems vs. when it adds unnecessary complexity
- Testing in legacy contexts: practical experience with unit and integration testing, particularly incrementally improving coverage in existing systems
