• Integrate WiFi modules and Ethernet interfaces, including driver development (ubxlib, NXP SDK, STM32 MAC/PHY)

• Implement and debug network protocols including lwIP TCP/IP, MQTT (v5 preferred), and TFTP/FTP

• Ensure robust and secure data communication using TLS, WPA3, PKI, and certificate-based methods

• Support secure boot processes, firmware over-the-air (OTA) updates, and TrustZone-based security features

• Apply best practices in debugging using JTAG, logic analyzers, Wireshark, and MQTT Explorer

• Contribute to compliance with aerospace standards, including ARINC 853 (CSMIM) and ARINC 615A

• Collaborate with cross-functional teams in hardware, systems, and product engineering to deliver high-quality solutions

What you need:

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or related field

• Proven experience in embedded system design and firmware development (C/C++)

• Strong background with STM32 microcontrollers and RTOS (FreeRTOS, ThreadX)

• Hands-on experience with lwIP TCP/IP stack, MQTT, and TFTP/FTP protocols

• Familiarity with WiFi modules, Ethernet interfaces, and driver integration

• Strong knowledge of secure communication standards (TLS, WPA3, PKI, TrustZone, Secure Boot, OTA updates)

• Proficiency in debugging and network analysis tools

• U.S. citizenship required; ability to work on defense-related projects

Nice to haves:

• Experience with aerospace-certified microcontrollers and compliance standards

• Knowledge of ARINC 853 (CSMIM) and ARINC 615A

• Prior defense, aerospace, or safety-critical system development experience

What we have to offer:

We are not just building components. We are reshaping the future of the Aerospace and Defense component industry, which is a $300B+ market! Come join us and help build next generation systems that will make a massive impact at global scale.

• We offer competitive compensation: $120,000 to $140,000 base salary + equity
