About The Role

We are looking for a Lead Software Engineer for the Billing Squad — one of the business‑critical teams. This is a technical leadership role for someone who writes code, not just manages people.

• Apply architectural patterns: SOLID, TDD, DDD, Event Sourcing, CQRS
• Participate in developing the billing/payments/invoicing domain, ERP integrations

Requirements

• 7+ years of development experience in C# / .NET — deep expertise
• 2+ years in a Team Lead or equal role (technical leadership)
• PostgreSQL — experience with relational databases
• RabbitMQ or similar message brokers
• Microservices + Docker
• Architectural patterns: SOLID, TDD, DDD, Event Sourcing, CQRS
• Technical leadership: code review, mentoring, hiring
• English — strong, able to work with C‑level (written and spoken at negotiation level)
• Proven experience managing VP and C‑level stakeholders

Nice‑to‑have

• AWS or Kubernetes
• Experience in billing, invoicing, payments, ERP integrations
• Knowledge of VAT/GST, accounting principles, revenue recognition
• Redis (additional platform service)

Soft skills / psychological profile

• A lead who writes code and doesn't avoid it
• Takes ownership of technical decisions
• Can communicate with business stakeholders
• Deep domain immersion (no job‑hopping)

Benefits

• Salary: €7,000 - €8,000 gross/month
• Contract: Full‑time, permanent employment
• Work format: Hybrid. Physical presence in the Netherlands required (Rotterdam office)
• Benefits:
  • Hybrid work from the Rotterdam office
  • Work‑life balance policy
  • Growth at the intersection of travel, finance, and engineering
  • Municipality parking card (for office employees)

Selection Process

• Recruiter screening — including knockout questions
