- Perform de-rating analysis, worst case circuit analysis, FMECA, and system reliability analysis.
- Support definition and implementation of hardware to software interfaces to implement control law and automated test functions.
- Support risk analyses, design for test/manufacture/cost, and root-cause analysis of test discrepancies.
- Architect and generate ASIC/FPGA RTL code
- Generate test cases and run simulations to verify functionality of ASIC/FPGA code
- Complete FPGA synthesis and resolve all errors/warnings
- Complete FPGA place and route and ensure sufficient timing margin through STA
- Complete electrical checkout of circuit cards/FPGAs for requirement verification/design validation
- Prepare materials for peer reviews and major design reviews
- Support rocket engine testing and ground support as necessary
Requirements:
- B.S. in Electrical Engineering with 10+ years of direct experience in electronics hardware and ASIC/FPGA development
- Demonstrated experience in delivering flight avionics for aircraft, launch vehicles, or other space applications.
- Understanding of analog/digital filtering, mixed-signal circuit design, analysis, and test.
- Knowledge of signal integrity, power, grounding, and general board layout principles
- Working knowledge of EMI/EMC practices and; MIL-461, DO-160, or FCC compliance
- Experienced in a hardware description language such as VHDL, Verilog or SystemVerilog
- Ability to use Python, TCL, or other high-level language for FPGA simulation and hardware test
- Experience with ASIC/FPGA timing closure and place and route
- Experience with Xilinx or Microsemi FPGAs
- Experience with electronic hardware, reading schematics and using hardware test and debugging equipment
Desired Experience:
- Direct experience in launch vehicle avionics systems integration
- Graduate degree in related engineering or technical field with 15+ years of direct experience in electronics hardware development
- Understanding of sensor and actuator technologies including: RTD’s, Pressure Transducers, DC brushless motors, Solenoid valves, Thermocouples, Hydraulic servo valves, LVDT, RVDT, Rotary/Linear Encoders.
- Demonstrated expertise designing Class 3 board assemblies
- Utilizing IPC and NASA-STD-8739.n (or similar) standards.
- Proficiency using Altium (or similar tools) to design complex boards; and experience working with external board manufacturing and assembly vendors.
- A desire to design mission critical hardware for flight applications.
- Working knowledge of high-reliability, radiation-tolerant, radiation-hardened flight hardware intended for high altitude and space environments.
- Proficiency with scripting; programming and analysis/modeling tools: Python, Linux/Windows shell scripting; assembly language, C, C++; MATLAB / Simulink / SPICE (or similar)
- Exposure to designing safety or mission critical aerospace flight hardware compliant with DO-254.
- Experience with SystemVerilog UVM, Cocotb or other PLI/DPI based co-simulation environment
Colorado law requires us to tell you the base compensation range of this role, which is $150,000 - $180,000, determined by your education, experience, knowledge, skills, and abilities. What we can’t quantify for you are the exciting challenges, supportive team, and amazing culture we enjoy.
