Job description

Senior Software Engineer, iOS & Android — eMSP & Driver Services

Are you ready to own the mobile experience that millions of EV drivers rely on every day? We're looking for a Senior Software Engineer to help lead the technical direction of our native iOS and Android apps on Europe's fastest-growing EV charging platform. This is a hands‑on role for a mobile engineer who raises the bar alongside a strong group of senior peers — in architecture, in code quality, and for the engineers around them.

About Us

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.

The Role

As a Senior Software Engineer on the eMSP & Driver Services team, you'll work across our native iOS and Android applications — both our own driver apps and the white‑label apps our eMSP customers ship under their own brands. You'll operate with wide latitude over technical decisions, working with the team's other senior engineers to set the architectural direction for the mobile codebase, make the design calls that keep it maintainable as it scales across markets, and hold the quality bar the rest of the team builds to. Your work directly shapes how drivers find, start, and pay for charging — where reliability and trust are everything.

What You'll Do

• Shape the technical direction: Drive architectural decisions for the iOS and Android codebases — modularization, state management, navigation, and the patterns that keep large mobile apps maintainable — together with the team's other senior engineers.
• Build the hard parts: Take on the most demanding features end to end — RFID and driver management flows, and the shared foundations behind our white‑label apps.
• 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 mobile engineers through design reviews, pairing, and direct feedback, growing the depth of the team around you.
• Drive cross‑team alignment: Partner with backend, product, and design on the contracts and decisions that span the mobile boundary, so the driver experience stays coherent end to end.

What We're Looking For

• Deep, demonstrated expertise building production mobile applications on both platforms: Kotlin with Jetpack Compose (Android) and Swift with SwiftUI (iOS).
• Strong command of modern mobile frameworks and the judgment to choose between them deliberately rather than by default.
• Fluency with modern concurrency on both platforms — Swift Concurrency (async/await, actors) on iOS and Kotlin Coroutines and Flow on Android — and the judgment to model async, event‑driven flows cleanly rather than defaulting to old patterns.
• A track record of architecting mobile codebases that stay maintainable as they grow — modular structure, clean separation of concerns, testability designed in rather than bolted on.
• 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.
• Experience with white‑label or multi‑tenant mobile products.
• Familiarity with both native platforms at depth, rather than primarily cross‑platform frameworks.

Why Join Us

• Own the mobile experience for millions of drivers across Europe.
• Real technical influence — your architectural decisions, made with a strong senior group, shape a codebase that scales across markets and brands.
• 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.
