We work as a team and depend on each other to learn quickly and put the new skills to good use. 

Responsibilities of your role:  

We are seeking a highly skilled Embedded Software Engineer to join our team. The successful candidate will play a crucial role in integrating cutting-edge radio hardware for commanding and operational purposes. 

As part of your role, you will: 

• Lead the firmware design and development of a cutting-edge satellite radio communication receiver.
• Collaborate effectively with cross-functional teams spanning multiple time zones, including RF, DSP and FPGA engineers to define system requirements and architecture.
• Design, develop, code, test and troubleshoot the system software to control and operate the radio hardware, ensuring compatibility, reliability and performance.
• Design and implement the software tools required for performance simulation and calibration of the hardware. 
• Create and maintain software documentation, including requirements, specifications and test plans.
• Optimize software performance and resource utilization for embedded systems with limited processing power and memory.
• Stay updated with industry trends and emerging technologies, contributing to the continuous improvement of our processes and methodologies.

Qualifications / Experience: 

• Extensive experience with embedded C/C++: interrupt handlers, concurrency, etc.
• Strong Linux skills: extensive CLI/scripting familiarity, kernel mods, drivers, etc.
• Experience with sensor integration over I2C, SPI, CAN, UART, etc.
• Software Design with memory, processor, and real-time constraints.
• Embedded Operating Systems (Petalinux, FreeRTOS, Yocto Embedded Linux).
• Scripting Familiarity: Python, Bash, etc.
• Experience with board bring-up.
• Data-driven and evidence-based work methodology.

Strong candidates will also possess skills in one or more of the following areas: 

• Proficiency in general hardware skills including understanding of Electrical Engineering principles, able to interpret electronic schematics with a solid understanding of digital electronics concepts.
• Knowledge of ARM/RISC profiling and optimizations for efficient embedded system performance.
• Understanding of networking protocols such as TCP/IP, UDP, and experience in protocol design for seamless and efficient communications.
• Experience with time synchronization protocols and techniques, such as NTP or PTP, for ensuring accurate and reliable timing in embedded systems.
• Previous experience in a high-reliability industry such as Automotive, Aerospace, Defence, Medical or in an embedded industry like IoT, Mobile Communications, or Distributed Sensor Networks.
• Domain Knowledge in Space technology and Radio Communications.
• Expertise in FPGA languages such as Verilog, VHDL, or HLS and ability to interface effectively with FPGA engineers.
• Familiarity with RF programming concepts, Software-Defined Radio (SDR) platforms, the USRP devices and GNU Radio for signal processing and communication applications.

Spire operates a hybrid work model, and this position will require you to work a minimum of three days per week in office.

Access to US export controlled software and/or technology may be required. #LI-DC1
