We are seeking an experienced Embedded Firmware Engineer to develop secure firmware for our Secure Element projects. The ideal candidate will have expertise in Public Key Infrastructure (PKI), Over-The-Air (OTA) updates, and Real-Time Operating Systems (RTOS). Your role will involve designing, coding, and testing firmware solutions, ensuring high security and reliability standards. If you are passionate about embedded systems and have a proven track record in firmware development, we would love to hear from you!This is a real hardware product. We are not looking for web or cloud engineers.
We need a senior embedded systems engineer who can own the firmware architecture for a production-ready device.
You will design and implement production-grade firmware including:
• Watchdog integration and fail-safe recovery
• Secure boot chain design
• OTA update system (dual-partition / A/B strategy with rollback)
• TLS client integration (mbedTLS / wolfSSL or similar)
• Secure element driver integration (hardware-backed key storage)
• Certificate provisioning & CSR flow
• Crash logging & persistent diagnostics
• Field-debug strategy (remote logs, safe recovery paths)
Must have real experience with:
• Embedded C / C++
• RTOS-based systems (FreeRTOS or similar)
• Secure boot implementation
• OTA update mechanisms that prevent device bricking
• TLS stack integration on MCU-class devices
• Hardware cryptography / Secure element integration
• SPI / I2C driver-level debugging
• JTAG debugging & hardware bring-up
