What you will do
We’re looking for a hands-on Software Engineer who will take ownership of end‑to‑end development of desktop applications (C#/.NET/WPF) that integrate with embedded products.
In this role, you’ll build software that connects physical devices to the cloud, work side‑by‑side with hardware and firmware engineers, and collaborate with Product and QA teams to deliver reliable, scalable solutions.
How you will do it
Design, build, and maintain desktop applications and supporting services using C#/.NET, primarily with WPF.
Develop software that connects devices to cloud backends, supporting IoT workflows such as device provisioning and OTA‑style updates.
Work closely with hardware and firmware engineers to design, implement, and debug communication between software and devices.
Troubleshoot and analyze communication issues using network and protocol diagnostic tools (e.g. Wireshark, logic analyzers, serial sniffers).
Drive root‑cause analysis and implement robust fixes across software and device integrations.
Document system architecture, interfaces, and operational processes to support smooth collaboration and long‑term maintainability.
Provide technical guidance and mentoring to junior engineers when needed.
