Embedded Software Engineer

Are you a seasoned software engineer who thrives at the intersection of low-level systems programming and cutting-edge wireless technologies? We're looking for a Staff Embedded Software Engineer to join our engineering team and serve as a technical pillar, architecting robust, power-efficient, production-ready software at scale.

• You’ll own software architecture and delivery for connected devices on Arm application SOCs, microcontrollers. Day to day you’ll be:
• Designing and implementing real-time firmware using FreeRTOS/Zephyr — task management, queues, semaphores, memory management, and power optimization
• Leading development of wireless protocol stacks including Wi‑Fi, BLE, UWB, and NFC
• Defining HAL abstractions and BSP strategies across hardware generations
• Championing secure boot, encrypted OTA, and key provisioning best practices
• Debugging complex system‑level issues with oscilloscopes, logic analyzers, and protocol analyzers
• Shaping our technical roadmap and influencing cross‑functional architecture decisions

• 10+ years of embedded software experience with at least 2 years in a Staff or Lead role
• Deep hands‑on expertise with FreeRTOS/Zephyr/Embedded Linux and ARM Cortex‑M microcontrollers/applications processors
• Proven experience with Wi‑Fi, BLE, UWB, and NFC protocol stacks
• Strong C/C++ skills for bare‑metal and RTOS‑based development
• Embedded Linux experience — including Yocto build system for production SOM/SBC platforms
• Hands‑on experience with NXP i.MX8/9 series application processors, board bring‑up, BSP customization, and peripheral driver development
• Cryptography and security fundamentals — AES, RSA/ECC, TLS/DTLS, secure key storage, and hardware security modules (HSM/SE)
• Solid hardware debugging skills — you’re comfortable with a schematic and a logic analyzer

• Experience with NXP RW612, STM
  32, or NXP i.MX9 series
• Background in Trust Zone, HSE, or secure element integration
• Yocto / embedded Linux open‑source contributions
• Knowledge of NFC standards (ISO 14443, ISO 15693, NDEF)
• Experience shipping firmware at high volume through manufacturing and field deployment
