Embedded Software Engineer

Belcan; Indianapolis (IN); Presencial; USD 90.000 - 130.000; Jornada completa

Descripción de la vacante

Belcan is seeking an Embedded Software Engineer to design, develop, and maintain firmware that runs directly on microcontrollers in collaboration with hardware engineers. The role emphasizes RF/wireless expertise, OTA updates, and robust debugging with J-Link/SWD/GDB.

The ideal candidate will have strong Embedded C skills for Cortex-M33, experience with Z-Wave, mesh networking, RF coexistence, and familiarity with Silicon Labs tools such as Simplicity Studio and related SDKs.

Formación

• Experience writing embedded C for ARM Cortex-M devices.
• Strong knowledge of bare-metal and RTOS firmware development.
• Proficient in interrupt-driven architectures and peripheral programming (DMA, timers, watchdogs, GPIO, UART, SPI, I2C).
• Experience with J-Link/SWD/GDB debugging and firmware update mechanisms.
• Familiarity with Silicon Labs wireless stack APIs and Simplicity Studio.

Responsabilidades

• Design, develop, and maintain embedded software tightly integrated with hardware.
• Collaborate with hardware engineers to optimize performance and power consumption.
• Implement OTA firmware updates and wireless protocol support (Z-Wave).
• Debug and validate firmware using industry-standard tools (J-Link, SWD, GDB).

Descripción del empleo

The Embedded Software Engineer is responsible for designing, developing, and maintaining software that operates directly on hardware systems. This role involves working closely with hardware engineers to ensure seamless integration and optimal performance of embedded systems.

Job Specific Requirements

• Embedded C (mandatory)
• Bare-metal and RTOS-based firmware
• Interrupt-driven architectures
• DMA, timers, watchdogs, GPIO, UART, SPI, I2C
• Bootloaders and firmware update systems
• Debugging with J-Link/SWD/GDB

The Silicon Labs EFR32 family is ARM Cortex-M33 based, so Cortex-M experience matters directly.

Wireless Protocol Expertise (Critical)

This is where average embedded developers get separated from actual RF/wireless experts.

Required Wireless Experience

You should strongly prefer candidates with experience in:

• Z-Wave
• Mesh networking
• RF coexistence
• OTA firmware updates over wireless

Especially valuable:

• Experience with Silicon Labs wireless SDKs
• Experience modifying MAC/PHY behavior
• Experience implementing custom protocol layers

Silicon Labs / Z-Wave Specific Skills

Because this is not just generic embedded work.

Strongly Preferred Experience with:

• Simplicity Studio
• Silicon Labs wireless stack APIs
• Z-Wave 700/800 series
• SmartStart
• S2 security
• OTA DFU mechanisms
• Zniffer packet analysis
• PTI packet tracing

Security Skills (Increasingly Important)

Modern wireless products require serious security awareness.
