Volledige vacaturetekst

You will lead the squad that runs one of C Teleport's most business-critical domains: invoicing, payments, reconciliation, VAT and revenue recognition across multiple jurisdictions. This is a leadership role with two halves that come together in one person: you own the technical direction of the squad and stay hands-on in the code, and you own the people — you build the team, grow it, and are accountable for how everyone in it performs.

At C Teleport we are transforming corporate travel by combining automation, machine learning and pragmatic engineering. The Billing Squad sits at the intersection of travel, finance and engineering, and its work is felt directly on the company's revenue. As its Lead, you are the squad's connection to the wider company — the technical counterpart to the squad's Product Owner, who is also based in our Rotterdam office, and a trusted partner to Finance and the management team.

What you'll own

Technical leadership

Own the squad's technical direction, from design decisions through to the implementation itself.
Own the squad's delivery outcomes — ensure the team ships reliable, complete solutions and follows through to production.
Stay hands-on: contribute production code, lead reviews, and know the system deeply.
Partner with the Product Owner to shape the roadmap and break work into incremental MVPs — shaping solutions, not accepting requirements blindly.
Challenge estimates, surface risks early, safeguard production stability, and keep incidents and support tickets inside SLA.
Enforce coding standards, reduce technical debt, and evaluate new technology with the Architects Group.

People leadership

Line-manage the engineers in the squad — this is real, all-round people management, not a title.
Own hiring for the squad: define the need, interview, and make the call.
Run regular 1:1s, give direct feedback, and build each engineer's growth path.
Own performance end-to-end: recognise and stretch strong performers, and address underperformance directly — including the difficult conversations and, where it comes to it, managing someone out.
Set and hold the bar for how the squad works together, and promote a culture of "agree or disagree, but commit."

This is not…

Not a hands-off management role. You will still design, review, and write production code every week.
Not a pure IC or architect role. You are accountable for people and for delivery, not only for the code. If you are looking to step back from management, or to step back from coding, this is not the role.

Must-haves (these are gates)

7+ years in software engineering with deep .NET / C# expertise.
2+ years leading engineers as a Team Lead / EM, with genuine appetite for the full people-management responsibilities above.
Strong hands-on coding background, you'd rather write code than avoid it.
Experienced with modern AI-assisted and agentic engineering tools, and able to use them effectively in day-to-day engineering and team management.
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.
Based in the Netherlands and able to work from our Rotterdam office 3 days per week. (We can sponsor highly-skilled-migrant candidates already in, or relocating to, the NL; we do not relocate candidates currently based outside the country.)

Nice to have (bonus, genuinely not required)

Experience on billing, invoicing, payments, ERP integration or other finance-related products.
Familiarity with VAT/GST, accounting principles or revenue recognition.
Experience with AWS or Kubernetes.

Tech stack

C#, .NET, PostgreSQL, RabbitMQ, AWS; alongside Docker, Redis, Elasticsearch and other supporting services across the wider platform.

The squad

A small, focused team: two senior full-time engineers and one QA engineer, working remotely across European time zones. From our Rotterdam office, you are the squad's connection to the wider company. You report to the CTO and work alongside a Tech Lead.

What we offer

A hands-on technical leadership role with significant ownership of a business-critical domain.
Hybrid working from our Rotterdam office, three days a week; close to your Product Owner and the people whose work depends on the squad, so the tightest collaboration happens in person.
Professional growth in a fast-moving company at the intersection of travel, finance and engineering.

Hiring process

Recruiter / HR call — role, motivation, logistics.
Short technical video call with our engineer.
Technical challenge / interview.
Meet the CTO.

Target: ~3–4 weeks end to end.

Pre-employment screening

If your application is successful, we may conduct a pre-employment screening through a trusted third party, in line with applicable laws — this may include employment history, education, and other relevant publicly available information to help us understand your suitability for the role.

C Teleport is an equal-opportunity employer. We assess every application on merit and handle your data in line with GDPR.
