Senior .NET Engineer

Senior .NET Engineer - Full-Time - 3 Open Positions

About us

We're a fast-growing fintech company on a mission to make digital payments smarter, simpler, and more transparent. We provide a data-driven online payment solution to a large and growing base of merchants across Europe, and we're working toward a future where buyers and sellers always have the information they need to make confident decisions. We believe in building smart, affordable payment infrastructure — and we're scaling fast.

The role

We're looking for a Senior .NET Engineer who loves the web, cares about clean, maintainable code, and isn't afraid of complex systems or legacy modernization. In this role, you'll build fintech features in .NET and C#, help redesign and modernize our existing applications, and work in a small, focused SCRUM team where your ideas and technical decisions have a visible impact. If you enjoy ownership from planning to deployment, value automation, and like to challenge the status quo, we'd be happy to get to know you.

What you'll be working on

- Building fintech features in .NET and C# that make payments faster and more secure

- Modernizing legacy applications into up-to-date software

- Creating technical plans for business requirements together with your teammates

- Operating within a SCRUM team (4–6 developers + Product Owner), involved across the entire software development lifecycle

- Participating in code reviews, deploying frequently, and monitoring the system in production

- Mentoring less experienced colleagues to help raise the team's overall technical level

What we're looking for

- Expertise in the .NET stack and the web — you can plan and build web projects in modern .NET, with strong command of ASP.NET, C#, and MS SQL, and confidence in caching, data distribution, and performance optimization

- Distributed thinking — experience working on distributed systems, with the ability to build microservices from scratch

- Monolith tolerance — you're not afraid of legacy code, and you have practical ideas for evolving it into a modern architecture

- A love of automation — whether it's CI/CD or AI, you look for ways to automate your own workflow

- Client-side skills as a bonus — comfort with the browser and JavaScript is a plus, not a requirement

- A self-driven attitude — you like seeing features through from planning to completion, and you're always keen to learn more

- Critical thinking — you're comfortable challenging the status quo and voicing your ideas

- Conversational English — the ability to understand and communicate in English is preferred

Hiring process

1. Initial introduction (30 minutes) — a conversation with the Hiring Manager covering an introduction to the company, an overview of the role, and a discussion of your background, experience, and career goals

2. Technical interview (1 hour) — a deep dive into your technical expertise and problem-solving skills with our Principal Engineer and a Lead Software Engineer, including an hour-long system-design exercise where you'll plan a new feature for an existing application. No live coding, no trick questions.

What we offer

- Competitive salary and attractive compensation packages

- Private health care with comprehensive coverage

- A warm, welcoming team culture that values humour, creativity, and the occasional meme

- Low-process, high-authority teams — so you can focus on real work instead of meetings

- A scale-up environment where your impact on the product is genuinely visible

- 3 days of home office per week for focused, uninterrupted development time

- A modern office, with a brand-new space currently in design and an upcoming move planned
