• Develop FPGA logic (VHDL or Verilog) for digital signal processing, communication interfaces, sensor integration, or high speed control functions
• Work closely with Embedded Hardware Design Engineers to define system architecture, validate interfaces, and ensure seamless hardware/firmware integration
• Implement and support communication protocols such as SPI, I2C, UART, CAN, RS 485, USB, Ethernet, Modbus, and other low and high speed interfaces
• Participate in schematic reviews and provide firmware related input to PCB layout for signal routing, timing, EMI/ESD mitigation, and overall system reliability
• Support system level testing, debugging, and validation using oscilloscopes, logic analyzers, JTAG/in circuit debuggers, protocol analyzers, and other lab equipment
• Develop test firmware, scripts, and automated test frameworks for prototype evaluation and production verification
• Create technical documentation, software requirements, architecture descriptions, and test procedures consistent with AS9100 quality standards
• Support compliance and qualification efforts to standards including AS9100, MIL STD 461, MIL STD 810, DO 704, and related specifications
• Collaborate with cross functional teams

Required Qualifications:
• BS in Electrical Engineering, Computer Engineering, Firmware Engineering, or related discipline
• Strong proficiency in embedded firmware development in C/C++ for microcontrollers and embedded processors
• Experience with RTOS based development, bare metal systems, interrupt handling, timing critical code, and power managed firmware
• Understanding of digital interfaces, communication protocols, and embedded system architectures
• Experience with lab equipment including oscilloscopes, logic analyzers, protocol analyzers, multimeters, and power supplies
• Familiarity with software configuration management, version control (Git), and structured engineering workflows
• Ability to read schematics and understand hardware-software interactions at the board level
• Candidate must be a U.S. Citizen and possess the ability to obtain and maintain a security clearance.

Preferred Qualifications:
• MS or PhD in Electrical Engineering, Computer Engineering, or Embedded Systems
• Experience developing FPGA logic in VHDL or Verilog, along with simulation, timing analysis, and synthesis workflows
• Experience with microcontroller families such as ARM Cortex M, PIC, AM2631 or embedded Linux based systems
• Familiarity with EMC/EMI considerations, signal integrity, and working with electronics designed for harsh environments
• Background in aerospace, defense, or ruggedized embedded systems development
• Experience implementing secure bootloaders, cryptography, OTA updates, and cybersecurity conscious embedded design
• Experience with MATLAB/Simulink, Python scripting, or automated hardware in the loop testing
• Knowledge of AS9100 documentation, configuration management, traceability, and structured design processes
• Experience collaborating deeply with hardware engineers and contributing to full lifecycle hardware/firmware co design

Desired Attributes:
• Strong analytical and problem solving skills
• High attention to detail and commitment to quality
• Clear communication and technical writing ability
• Ability to work both independently and within multidisciplinary teams
• Passion for innovation and mission oriented engineering
