Job description

At Zaptec we're looking for a Senior Backend Developer to join our team.

We combine the latest tech with human-centered design to offer highly intuitive and efficient EV chargers that ensure easier access to personal electric transport.

This gives people the freedom and potential to travel into a more sustainable future. How neat is that?

Within just a few years, we’ve built our domestic market‑leading position by supplying superior charging installations for housing co‑ops and private homes alike.

As a Norwegian EV pioneer, our goals are aimed at bringing the best charging technology to the rest of the world. Are you up for this challenge?

At Zaptec, we build technology that powers the shift to electric mobility across Europe. Our charging solutions connect thousands of devices in the field with intelligent cloud services. Securely, reliably and in real time.

We’re now looking for a Senior Backend Developer to join one of our cross‑functional product teams. This is a role for someone who thrives in complex distributed systems, enjoys real ownership, and wants to influence how scalable cloud services are built and evolved.

You won’t just implement features. You’ll help shape the systems behind them.

You’ll work hands‑on in the core of our backend platform, the services that power real‑time charging, device communication and business‑critical functionality across markets.

What your day might include

• Designing and developing backend services in .NET (C#)
• Building and evolving scalable, resilient and secure cloud‑based solutions
• Contributing to architectural discussions and technical direction within the team
• Reviewing code, mentoring colleagues and raising the overall engineering standard
• Monitoring, troubleshooting and optimising production systems
• Operate in a world‑leading IoT environment where hardware, firmware and cloud services must work seamlessly together, and at scale.

You’re an experienced backend engineer who naturally takes ownership, not because you’re told to, but because you see what needs to be done. You’re comfortable operating in complex systems where reliability, scalability and long‑term thinking matter. Writing clean, maintainable code isn’t a goal in itself, it’s simply how you work.

You think beyond the ticket in front of you. You care about reducing technical debt, improving architecture and building solutions that will still make sense a year from now. You’re used to collaborating across disciplines, contributing to technical direction and challenging decisions constructively when needed.

You stay curious, you stay pragmatic, and you know how to balance engineering excellence with momentum. You don’t need the “architect” title to think architecturally.

Some personal skills we value

• Strong problem‑solving abilities
• Clear and open communication
• A structured and analytical mindset
• The ability to challenge constructively, and to be challenged
• A genuine interest in technology and sustainable innovation

At Zaptec, we believe great engineering is built on trust, collaboration and respect.

Skills required for this job

• Experience building and maintaining scalable cloud‑based solutions
• Experience with Azure SQL and/or PostgreSQL
• Experience with Entity Framework or similar ORM
• Experience with monitoring and observability tools (e.g. Grafana, Prometheus, Log Analytics, OpenTelemetry)
• Understanding of containerisation and distributed systems
• Fluent in English, written and spoken
• It’s a bonus if you have experience with frontend technologies like React, JavaScript, CSS and/or HTML.

Join in! ☕️ Yes, we do spend a lot of time in front of our desks, but we also love coffee, conversations, nerdy talks, lunches and jokes. 🤡

Benefits

• We trust you do your job, flex your own day.
• We’ll provide the hardware you need.
• Career growth & competence development.
• Pick your favourite Zaptec gear - it’s on us.
• We got your back in regards to insurance and pensions.
• Take part in our yearly bonus scheme.
• Don’t forget social events.

We strive to be the best at what we do, both in the eyes of our customers and our coworkers. We believe in a flexible and trustworthy way of working. We focus on results, not necessarily the approach because we respect that each coworker has unique ways of working to reach the target. 🙌🏽

Customer experience is the core of everything we do to provide a worry‑free EV life.

We believe in our employees' uniqueness and the multidisciplinary way of working, and we work collaboratively toward a common goal.

Zaptec's products and services are making a difference to EV drivers, as we provide EV owners the freedom to charge from home and explore new adventures. By joining our team, you are joining us in our mission to create a more sustainable and electrical future, providing user‑oriented EV charging experiences.

Surround yourself with highly motivated fellow Zapiens who support one another to reach our common goal. At Zaptec, you will impact improving the EV journey globally.

We don't care about your background, gender identity, sexual orientation, religious beliefs or age. We do care about equal respect. We're just humans. And sometimes we fuck up.
