About the Position

Senior Embedded Software Developer (Security)

Location: Wroclaw, Poland

About the Project

Join a strategic partnership with a global leader in long-range wireless technology to architect the software ecosystem for a next-generation multi-core System-on-Chip (SoC). This engagement goes beyond standard firmware development; you will co-develop a comprehensive developer platform that transforms complex multi-core hardware into an accessible, world-class microcontroller product. By leveraging open-source real-time operating systems like Zephyr and FreeRTOS, and implementing cutting-edge hardware-enforced security frameworks (PSA Level 3, TrustZone, TEE), you will empower the global embedded community to deploy secure, ultra-low-power IoT applications. You will work within a specialized team structure to deliver a modern toolchain centered around Visual Studio Code, ensuring a seamless “edit-build-debug” experience for the next wave of wireless innovation!

Your Role

Implement hardware-enforced memory partitioning using ARM TrustZone and configure the Secure Processing Environment (SPE);
Develop the Secure Enclave driver layer and PSA Crypto API to leverage hardware accelerators;
Contribute to building and maintaining a secure bootloader featuring firmware signature verification and anti-rollback protection;
Design security frameworks, cryptographic APIs, and secure boot processes for highly resource-constrained, bare-metal architectures (e.g., DSP/Radio cores) where traditional RTOS or hardware isolation is unavailable;
Execute the Secure Software Development Life Cycle (SSDLC), managing static code analysis and addressing vulnerabilities from penetration testing;
Prepare the security architecture and documentation to meet PSA Level 3 and SESIP3 certification standards;
Implement side-channel (DPA) protection measures within the cryptographic drivers.

Requirements

6+ years in embedded development;
Extensive experience with C programming language;
Extensive experience with ARM TrustZone technology and secure memory partitioning;
Strong background in embedded security standards, specifically PSA (Platform Security Architecture) Level 3 or SESIP3;
Proficiency in implementing secure boot chains and root of trust provisioning;
Experience with cryptographic algorithms and hardware acceleration drivers;
Familiarity with static security analysis tools and vulnerability management workflows.

Nice to Have

Experience with MCUboot or similar open-source bootloaders;
Knowledge of the EU Cyber Resilience Act (CRA) or US Cyber Trust Mark requirements;
Knowledge of secure provisioning processes for manufacturing.

We Offer

Flexible work schedule;
Private healthcare insurance - LuxMed (extended gold package for parents & kids);
Multisport card;
Workation;
Financial bonuses for significant life events (wedding, birth of a child);
Compensation of professional training: courses, seminars, trainings (it is decided for each person individually if the whole thing or a part of it will be covered);
Author's right (for those who write the code).
