Position

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, writing production code — and deep in the domain, with a working grasp of pricing, invoicing and reconciliation. You'll act as the Product Owner's technical counterpart — actively shaping solutions rather than accepting requirements blindly — and engage directly with Finance and the company management team as a trusted technical partner.

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 escalate 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."

Your qualification

• 7+ years in software engineering with deep .NET / C# expertise, including 2+ years in a Team Lead or equivalent role.

• Strong hands-on coding background — you'd rather write code than avoid it.

• Solid grasp of architectural patterns, SOLID, TDD, DDD, Event Sourcing and CQRS.

• Practical experience with relational databases (PostgreSQL preferred) and message brokers (RabbitMQ or similar).

• Hands-on with microservices and Docker; experience with AWS or Kubernetes is a plus.

• Curiosity for modern and emerging tech — you keep your stack and your knowledge current.

• Excellent attention to detail and a get-it-done attitude.

• Strong English communication; able to translate business needs into clear technical work, when Product Owner is not around.

• Proven ability to mentor engineers and drive cross-functional collaboration.

Will be a plus

• Prior experience on billing, invoicing, payments, ERP integration or other finance-related products.

• Familiarity with VAT/GST, accounting principles or revenue recognition.

What we offer

• A hands-on technical leadership role with significant ownership of a business-critical domain.

• Hybrid working from our Rotterdam office, in a collaborative international team.

• Competitive salary and benefits, with a company policy that supports work-life balance.

• Professional growth opportunities in a fast-moving, tech-driven company at the intersection of travel, finance and engineering.
