Role

Who you are

You're pragmatic, learn quickly, and have a proven track record of shipping products that matter. You communicate clearly across disciplines and genuinely enjoy the dynamics of a cross-functional team where everyone contributes to solving the same customer problems
Above all, you're curious – about the product, the users, the business, and how your technical decisions impact all three
As a product-minded backend engineer, you don't just implement tickets. You understand the "why" behind what you're building, challenge assumptions when needed, and proactively identify opportunities to create better outcomes
You're comfortable discussing trade-offs with product managers, explaining technical constraints to business stakeholders, and collaborating with frontend and mobile engineers to design elegant end-to-end solutions
You have deep expertise in .NET and C# with a strong appreciation for maintainable, scalable code, and distributed architectures. But more importantly, you know when to apply that expertise and when simpler solutions serve the product better
You've built data-intensive applications before and understand the concepts of working in a regulated environment
You take ownership not just of your code, but of the outcomes. You move without being prompted, whether that's jumping into a customer issue, improving team processes, or mentoring colleagues
You're curious about adjacent domains – you might peek at the frontend code, ask questions about the ML models, or dive into analytics to understand how features perform
Quality is non-negotiable for you. Automated testing, thorough code reviews, and security best practices are fundamental to how you work. You balance technical excellence with pragmatism, always keeping the end user and business goals in mind
At least 5 years of professional backend development with a product engineering mindset
Excellent knowledge of .NET platform and C#
Hands-on experience architecting and evolving distributed systems in production
Proven ability to collaborate effectively with product managers, designers, and engineers from other disciplines
Strong business acumen – you understand how your work connects to company objectives
Clear, concise communication in English across technical and non-technical audiences
A builder's mentality: you care deeply about shipping great products, not just writing great code

What the job involves

We're looking for a Senior Backend Engineer who thinks like a product builder, thrives in a collaborative, cross-functional environment, and is passionate about creating robust, scalable financial infrastructure
You'll be part of a domain team where various engineering crafts (Backend, Frontend, Mobile, ML/AI engineers, and QA) work together to own and evolve a shared product area that delivers real value to hundreds of thousands of businesses across Europe

Our take

Financial services can be complicates and time-consuming, especially for smaller companies, early-stage businesses, and freelancers. And navigating everything from invoices to expenses can often pull focus away from actually running the business.

Founded by the team behind the online B2B bank Modulbank, Finom is the fastest-growing financial management platform SMEs and freelancers. Its automates tools cover everything from expense tracking to e-invoicing to multi-banking, and it's even supported by partnerships with the likes of VISA and Klarna.

This rapid growth is backed by strong investor confidence too, with some significant funding added to its name in 2025. The capital will support customer acquisition, product expansion, and strategic initiatives. And with ambitions to reach 1M businesses customers by the end of 2026, Finom is seriously setting its sights high.
