Senior Software Engineer

Our client develops IoT-powered, data-driven solutions that improve sustainability, reduce emissions, and increase safety on roads worldwide. With over €60 million in funding, their cloud-native SaaS ecosystem ingests and processes vast streams of data, enabling advanced analytics, automation, and integration across a wide range of industries - from mobility to logistics.

Role Overview:

The Senior C# Full Stack Engineer will join the Extensibility Team, responsible for owning and expanding the platform’s modular integration layer - including its add-on marketplace, partner-facing APIs, and custom modules that connect third-party business systems with IoT data flows. You’ll work across services and interfaces that allow customers to tailor and extend the platform’s capabilities in meaningful ways.

This is an opportunity to work on complex technical challenges involving high-volume data, integration patterns, and cross-system orchestration - in a team that sits at the centre of extensibility and connectivity.

Key Responsibilities:

• Develop and maintain C# services that power the platform’s extensibility and modular integration capabilities
• Build and evolve REST and GraphQL APIs, data feeds, and SDKs used by both customers and internal teams
• Contribute to frontend components for the add-on marketplace and integration UI.
• Work in a cloud-first environment (AWS) to ensure scalability, performance, and security of all integration layers
• Support the team’s CI/CD pipelines and test automation frameworks, helping ensure smooth delivery
• Collaborate with product and engineering to shape how the platform connects to the outside world

Qualifications:

• Solid experience in C# Fullstack backend development.
• Hands-on experience with AWS-based development and deployment.
• Exposure to frontend development (ideally, Angular.js or similar frameworks).
• Familiarity with DevOps workflows, including CI/CD, infrastructure as code, and test automation.

If you’re excited about working at the intersection of IoT, cloud infrastructure, and extensible platform architecture - and want to help build the integration layer of a product used at scale — we’d love to hear from you.
