Senior Software Engineer — Hinnoittelu & Rahoituspalvelut - Virta Ltd - Helsinki, Suomi

Are you ready to own the systems that decide what every EV charging session costs — and make sure the money flows correctly behind it? We're hiring two Senior Software Engineers for our Pricing & Finance Services team on Europe's fastest-growing EV charging platform. This is a backend role for engineers who take correctness seriously: the code you write sets tariffs, calculates settlements, and invoices customers, where a rounding error isn't a cosmetic bug. Virta is Europe's fastest-growing electric vehicle charging platform, operating in 36+ countries with 600,000+ charging stations. Headquartered in Helsinki, with offices in Berlin, Stockholm, Paris, Singapore, and Bucharest, we're shaping the future of e-mobility with a talented, multinational team. Virta is among the rare 65 companies that made the FT 1000 list four consecutive times. As a Senior Software Engineer on the Pricing & Finance Services team, you'll build and evolve the services behind pricing, tariffs, settlements, and invoicing — the financial core that turns charging sessions into correct, auditable transactions for both external customers and internal teams. You'll operate with wide latitude over technical decisions, working with the team's other senior engineers to set the architectural direction, make the design calls that keep these systems correct and maintainable as they scale across markets, and hold the quality bar the rest of the team builds to. Where money and pricing logic meet, the cost of getting it wrong is real — and so is the impact of getting it right. Shape the technical direction: Drive architectural decisions across the team's services — data modeling, service boundaries, and the patterns that keep financial logic correct and testable — together with the team's other senior engineers. Build the hard parts: Take on the most demanding work end to end — pricing and tariff logic, settlement and invoicing flows, and the APIs that expose them to external and internal customers. Engineer for correctness: Treat accuracy, auditability, and idempotency as first-class requirements, not afterthoughts, in systems where transactions must reconcile exactly. Define quality standards: Help establish the testing strategy, review practices, and release discipline the team builds to — and lead the response when something breaks in production. Raise the team: Mentor engineers through design reviews, pairing, and direct feedback, growing the depth of the team around you. Drive cross-team alignment: Partner with product, transaction operations, and other engineering teams on the contracts and decisions that span service boundaries, so the financial picture stays coherent end to end. Deep, demonstrated expertise building production backend services, with strong command of TypeScript and NestJS (our primary stack) and comfort working in PHP, which still runs parts of the platform. A track record of designing backend systems that stay correct and maintainable as they grow — clean service boundaries, separation of concerns, testability designed in rather than bolted on. Strong data modeling and SQL skills, and the judgment to design schemas and transactions that hold up under financial-grade correctness requirements. The ability to operate independently with wide decision-making latitude, owning significant technical decisions and seeing them through. Experience mentoring engineers and setting quality standards that others follow. Comfortable using AI coding tools in a senior workflow, with the judgment to know where they help and where they don't. We treat AI-generated code as a first draft, held to the same review bar as anything else. Excellent communication skills in English. Willingness to work onsite on a regular basis (hybrid working). Residency and working rights in Finland. Nice to Have: Experience in the EV charging, energy, mobility, or IoT sectors. Background in billing, payments, settlements, accounting systems, or other domains where financial correctness is non-negotiable. Experience evolving services out of a legacy monolith toward a domain-oriented architecture. Familiarity with event-driven design and the trade-offs of asynchronous processing in transactional systems. Why Join Us: Own the financial core of a platform serving millions of charging sessions across Europe. Real technical influence — your architectural decisions, made with a strong senior group, shape systems where correctness directly affects revenue. A culture that values evidence over hype: deliberate technical choices, honest review, and direct communication. International, passionate team spread across our European offices and beyond. Hybrid work with autonomy and flexibility. Ready to build what's next? Submit your application and help us build the financial foundation for the future of electric mobility.
