[Hiring] .NET Developer @Deftpower

Role Description

The Transactions team is a team of backend developers and a tech lead. The team owns everything financial in the platform: invoices, payments, ledgers and reconciliation with every partner. You work most with your tech lead, our product owners and the operations engineers.

Every charging session on our platform ends in an invoice and a payment. As more drivers charge with more brands, that volume grows, and downtime is not an option. We need another developer to keep it reliable while we keep building.

You build and run the backend services behind every euro that moves through our platform. You decide how a feature is built and how we make it hold up at scale.

• Build invoicing, subscription and voucher features in C# and .NET
• Integrate payment service providers, including Deftpay, our own white-label payment provider
• Keep every ledger correct through reconciliation
• Strengthen fraud measures, such as reserving money before a charging session starts

After six months, you've shipped a feature from shaping to production, for example in invoicing or subscriptions.

We work with Shape Up instead of Scrum: six-week cycles with a clear goal, and the team decides how to get there. An operations squad picks up the bugs, so you can focus on building.

Qualifications

• 3+ years of experience as a backend developer in C# and .NET
• Experience building APIs and integrating them with external systems
• Ability to work in English daily; Dutch is nice to have

Requirements

• C# and .NET, SQL (SQL Server / EF Core), Azure (Functions, Service Bus, Azure SQL), Git and pull requests
• Curiosity about AI coding tools

Benefits

• 8% holiday allowance
• 25 vacation days
• Good pension
• €2,000 training budget a year and your own choice of laptop
• 40 hours a week, or 36 if you prefer
• On average 2 days a week at the office in Arnhem

Company Description

We make EV charging less annoying. Drivers find a charger, pay with one app or card across Europe, and charge at moments that are easier on the grid.

Three e-mobility experts founded Deftpower, and they still run it. You can walk up to any of them, or to anyone else, with a question. Most people tell us they learn more from their colleagues here than from any course.

We're 120+ people now, with the energy of a team of 30. We'll keep growing, just more deliberately than before.

Everyone is driven to make customers happy. We don't just work for the sake of working.
