Lead Software Engineer— Billing Squad, Rotterdam

Are you a senior engineer who believes leadership is earned at the keyboard, not the standup? Do you bring a deep technical background, attention to detail and a get-it-done attitude— the kind of engineer who finishes the job, edge cases included? Are you ready to take ownership of one of the most critical and complex product domains in a fast-growing travel tech company?At C Teleport, we are transforming corporate travel by combining automation, machine learning and pragmatic engineering. The Billing Squad owns one of the company's most business-critical domains— invoicing, payments, reconciliation, VAT and revenue recognition across multiple jurisdictions. As Lead Software Engineer for the Billing Squad, you will set the technical direction, contribute directly to the codebase, and keep the squad's stack current with modern and emerging technologies —partnering closely with the Product Owner, Architects and QA to deliver reliable, secure and scalable solutions sprint after sprint.This is not a hands‑off management role. We expect our Leads to be deep in the codebase — shaping designs, reviewing code, and writing production code themselves. Key Responsibilities

Own the squad's technical direction, from design decisions through to the implementation itself. Stay hands‑on, contribute code, lead reviews, know the system. Partner with the Product Owner to shape the roadmap and break work into incremental MVPs. Challenge estimates, surface risks early, and upscale when needed.Safeguard production stability and ensure incidents and support tickets are handled within SLAs. Enforce coding standards and continuously reduce technical debt. Evaluate and adopt new technologies in consultation with the Architects Group. Mentor engineers in the squad and contribute to hiring decisions.Liaise between Engineering and Product, QA, Support and Architecture. Promote a culture of "agree or disagree, but commit."
