Job description

20,800 – 26,000 PLN

Important: if an employer asks you to log into their system via iCloud or Google, send a code, an SMS or Telegram password, run some code, or install software — refuse. These are signs of fraud.

Secure boot, firmware security, OTA updates.

Cryptography (AES, RSA, ECC) & hardware security (TPM, HSM, TrustZone).

Embedded interfaces & protocols: CAN, LIN, Modbus, BLE, Wi-Fi, TCP/IP.

Penetration testing on embedded targets: JTAG, UART, SPI, I²C.

Secure code review (C/C++, Rust, Python) & DevSecOps / CI/CD security.

Requirements:

Strong experience in embedded systems, IoT security, or product cybersecurity.

Hands‑on knowledge of secure boot, firmware protection, code signing, and secure update mechanisms.

Deep understanding of cryptography and key management in embedded environments.

Experience securing communication protocols and network interfaces in connected devices.

Knowledge of IoT authentication, authorization, and cloud security architectures.

Experience with threat modeling methodologies such as STRIDE, DREAD, and Attack Trees.

Ability to perform security risk assessments aligned with: ISO 21434, IEC 62443, ISO 27005.

Understanding of common embedded attack vectors: side‑channel attacks, fault injection, firmware tampering, replay attacks, MITM attacks.

Experience conducting penetration testing on embedded targets using interfaces such as JTAG, UART, SPI, and I²C.

Experience with fuzz testing communication stacks (CAN, TCP/IP, MQTT).

Understanding of secure SDLC principles, DevSecOps, and cybersecurity lifecycle management.
