  • Low-Level Integrity: Design firmware for RTOS with a focus on memory protection, deterministic behaviour, and secure hardware interfacing (SPI, I2C, UART);
  • Cyber-Security Implementation: Integrate security controls such as encryption (AES, RSA), Secure Boot, and Hardware Root of Trust (TPM/HSM);
  • Cross-Platform Integration: Ensure seamless and secure communication between C# high-level applications and low-level embedded targets.

What You’ll Bring

  • Languages: Proficiency in C, C++ (Embedded) and C# (Application level);
  • Windows Ecosystem: Expert use of Microsoft Visual Studio for both C++ and .NET development;
  • Linux & Yocto: Experience with Embedded Linux and the Yocto Project (BitBake);

  • Security-First Mindset: Knowledge of cryptographic libraries, secure communication protocols (TLS), and vulnerability mitigation;
  • IDEs: Proficient in Visual Studio and Eclipse-based environments.

Benefits

  • Competitive compensation package aligned with experience.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
