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.

What we look for

Required

• 5+ years of professional software development experience, with strong hands‑on C#/.NET production work.

• Solid experience building real‑time desktop applications using WPF and architectural patterns such as MVVM.

• Hands‑on experience with device communication and hardware/software integration (serial buses, TCP/IP, low-level debugging).

• Knowledge of hardware tools (oscilloscope, logic analyzer etc..).

• Strong software engineering fundamentals in object‑oriented design, data structures and algorithms, asynchronous programming, concurrency, and multithreading, memory and performance profiling.

• Excellent collaboration skills and experience working with Product, QA, and Hardware teams.

• Familiar and passionate of the latest AI coding tools such as CloudCode, Antigravity, GitHub Copilot or similar. 

• Advanced English, both written and spoken.

Preferred

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Software Engineering.

• Experience building IoT solutions that connect devices to cloud services (especially AWS: S3, Lambda, API Gateway, Cognito).

• Background in embedded systems, or close collaboration with firmware teams.

• Familiarity with wireless protocols and smart‑home technologies (e.g. RF, Zigbee, Z‑Wave, Wi‑Fi).

• Experience with Python or Bash for tooling and automation.

• Exposure to SQL Server or Oracle; familiarity with SSRS or SharePoint.

• Experience with Xamarin, .NET MAUI, or other cross‑platform UI frameworks.

• Understanding of security best practices for connected devices and cloud services.
