At Weheat, we connect thousands of heat pumps to the cloud and turn real-time data into lower energy bills and lower CO₂. As a Backend Engineer you’ll ship scalable .NET services, work hands-on with real devices (from hardware to the cloud), and see your code used by tens of thousands of people and installers.
What you'll do
Design & ship robust C# APIs (ASP.NET Core) for our mobile app, installer tools and IoT devices.
Build data pipelines for real-time telemetry, analytics and diagnostics.
Scale in Azure: serverless services, microservices and edge processing.
Raise the bar on security & reliability (authN/Z, encryption, monitoring, CI/CD).
Collaborate end-to-end with UX/Product Design, Front-end and Firmware/Hardware to deliver device → cloud → app features.
Our stack:
Languages & Frameworks: C# / .NET (ASP.NET Core, background services). Python for data tooling is a plus.
Data: TimescaleDB (time-series) and MongoDB (NoSQL) + solid SQL.
APIs & Messaging: REST, real-time streams/events. (No GraphQL.)
Don’t tick every box? That’s okay—bring strong fundamentals and curiosity and you’ll grow into the rest.
You’ll fit right in if you…
Have ~1–4 years of backend experience (or strong projects) with C#/.NET.
Understand databases (SQL/NoSQL), indexing and clean data models.
Know the basics of cloud deployment and Docker — or learn quickly.
Enjoy ownership, clean code and solving tough problems with teammates.
Are curious, practical, and motivated by real-world impact.
What we offer
An ambitious scale-up with a sustainable mission, short lines of communication, and plenty of ownership.
The chance to visibly grow a young brand (±3 years old): already 200+ installer partners, winner of the National Entrepreneurs Prize, and thousands of homes heated.
A steep learning curve with talented, driven colleagues who keep challenging you.
Great equipment (laptop/phone) and on-site collaboration with a passionate team at our office in Duizel (Eindhoven region) with top-tier facilities. We work on-site because it’s part of our success formula.
A company culture with a winning mindset: real responsibility, clear purpose and impact, working alongside other top talent.
