Senior Backend Developer - Business Development Team

As a Senior Backend Developer in our Business Development team, you will play a key role in driving digital solutions that help us create value for our customers and accelerate progress towards fossil freedom. Your expertise in building enterprise-grade production-ready solutions with .NET and Azure will be central to developing and maintaining robust backend applications, enabling innovative customer solutions with lasting impact.

Working alongside other backend and front-end developers, as well as business stakeholders, you will apply your experience to take a variety of applications into production, ranging from event-driven and messaging-based systems (e.g., Kafka) to cloud-native services on Azure. You’ll bring a flexible, hands-on mindset and the versatility to contribute across different parts of the stack as needed.

Your Daily Responsibilities Include:

• Designing, building, and maintaining production-ready backend services using .NET on Azure
• Producing clean, maintainable code with strong tests, documentation, and sensible patterns
• Driving technical decision-making (trade-offs, performance, reliability, cost)
• Implementing event-driven architectures that support efficient communication between systems
• Collaborating closely with developers and stakeholders to deliver complete solutions, owning features end-to-end: discovery, design, implementation, testing, deployment, monitoring

You will contribute to architectural decisions by applying your technical insight and experience, always considering the needs of both the business unit and our customers. Success in this role means creating secure, high-performing systems that support new business opportunities while helping colleagues grow through open collaboration.

By championing quality standards and sharing knowledge openly, you help shape an environment where every solution is stronger because it’s built together.
