Technical Team Lead

Our goal? To kick-start a true revolution within the accountancy sector! Help us introduce groundbreaking features that redefine industry standards!

Your role

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 impact

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 bring

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.
