As Tech Lead, you take full ownership of your squad's technical delivery and architecture — whether that's driving commercial growth features or building the internal platform that powers our engineering organization. You stay hands-on, using your deep .NET and Vue.js expertise to ship high-quality code. Together with your Trio (Product Owner, Designer, and Tech Lead) and fellow Tech Leads, you shape our technical roadmap. And you don't just deliver what's next: you look for ways to keep pushing our stack forward.
Time to grow. Time to thrive.
We are Nmbrs. We build smart business software that removes unnecessary complexity for SMEs and the professionals who support them. Nmbrs brings together four established product organisations - Payroll, Accounting, Invoicing and Reporting - with teams across the Netherlands, Sweden and Portugal.
We are one brand with a shared ambition, while continuing to work from the expertise and strengths of our individual organisations. We join forces where it makes sense, while keeping teams, expertise and decision-making close together.
For this role, you'll join Nmbrs Accounting in Rotterdam, working closely with the colleagues in your local team while being part of the wider Nmbrs organisation.
We are currently hiring two Tech Leads for two distinct, high-impact teams within our development organization: Team Growth and Team Platform.
As Tech Lead, you focus entirely on code quality, architectural integrity, and the successful delivery of your squad's roadmap - staying hands-on by developing within your scrum squad while acting as the technical bridge between product and execution. All people-management responsibilities (career growth, 1-on-1s) are handled by our Software Development Managers, so this role stays fully dedicated to engineering.
Team Growth
This team focuses on building features that directly drive our commercial growth - think cross-sell and upsell opportunities within the platform. As Tech Lead here, you help us move fast, experiment with new revenue-driving features, and turn commercial insights into scalable technical solutions.
Team Platform
This team focuses entirely on the system-technical foundation of Nmbrs Accounting - the internal tools, infrastructure, and integrations with other Visma solutions that support our whole engineering department. As Tech Lead here, you keep the tools and infrastructure our developers depend on robust, reliable, and scalable.
(During the intake conversation, we'll walk you through both team dynamics in detail, so together we can figure out which challenge fits your expertise best.)
In practice, you will:
Technical authority in the Trio: Act as the technical authority within the Product Owner / Designer / Tech Lead trio, ensuring the roadmap is technically feasible and optimized for long-term scalability - and own your team's delivery, setting priorities and managing the technical roadmap so milestones are met.
Architecture & strategy: Oversee the technical direction of your squad, spot opportunities to improve our solutions, and lead initiatives that push our stack (both .NET and Vue.js) forward.
Hands-on development: Lead by example - stay actively involved in the codebase, ship high-performing features, and solve complex technical challenges alongside your team.
Quality & mentorship: Safeguard our engineering standards through code reviews, and mentor other developers to sharpen their technical skills and adopt best practices (without owning their formal HR or growth cycles).
Cross-functional alignment: Collaborate directly with other Tech Leads, our CTO, and Software Development Managers to align your team's goals with the broader organizational architecture.
Your work determines how fast and reliably your team's part of the platform evolves - whether that's a new upsell feature going live for Team Growth, or Team Platform's internal tooling keeping every other engineering team unblocked. When you get the architecture right, your squad ships with confidence instead of constantly firefighting technical debt.
You're also shaping how technical leadership works across Nmbrs Accounting: as one of several Tech Leads working closely with the CTO and Software Development Managers, your decisions ripple into how the whole engineering organization approaches architecture and delivery.
You're a technical reference point with an autonomous, analytical mindset and strong organizational skills. You're passionate about writing clear, maintainable code, and you know how to translate complex technical concepts to non-technical stakeholders like your Product Owner and Designer.
5+ years of experience in software development, with deep expertise and a strong focus on backend frameworks (.NET/C# and SQL Server).
Previous experience in a Tech Lead role, or as a senior developer with responsibility for technical roadmaps and delivery.
A solid understanding of web, SPA, and component architecture, backend design patterns, database optimization, and API development (RESTful).
Solid knowledge of web security and cross-browser compatibility.
A strong sense of ownership over your squad's output, and the communication skills to prioritize technical tasks against business goals and explain trade-offs to non-technical stakeholders.
You don't need to tick every possible box. If you recognise yourself in the role and believe you can make an impact, we'd like to hear from you — let us know in your application (or during the intake) if you have a preference between Team Growth and Team Platform, or if you're open to either.
Personal development: A generous training budget, available directly after your probation period, for specialized certifications, courses, and training to solidify your technical expertise.
Time off and flexibility: 28 vacation days (and the option to buy 5 extra days), plus the possibility of Workation: up to 5 weeks per year of remote work.
Well-being & focus: Access to lifestyle coaches, healthy lunches, and other initiatives that contribute to your well-being and focus, including the possibility to lease a bike via Lease-a-Bike.
Financial security: A competitive base salary with attractive benefits, such as full pension coverage.
Optimal workplace: The best hardware, including a home-office budget to set up your remote workspace.
Plenty of opportunities: Enjoy the speed and autonomy of an innovative scale-up, backed by the stability, vast resources, and global career network of the Visma Group.
Team & culture: Participate in team-building days and other Nmbrs events that strengthen the close team spirit in a diverse and international environment.
