Avionics Design Engineer

The Role & Impact

As a Avionics Design Engineer at Logos, you will not just draw schematics-you will architect, build, and field high-bandwidth flight processing units and avionics that power our next-generation LEO constellation. You will own flight hardware across its entire lifecycle, taking vague, complex design concepts and translating them into flight-ready hardware that survives and thrives on-orbit.

Key Responsibilities

• End-to-End Design Ownership: Architect and design flight avionics, high-speed processing boards, and payload digital systems from initial architecture through schematic capture, layout guidance, and bring-up.
• Advanced Analysis: Conduct Signal Integrity (SI), Power Integrity (PI), Worst-Case Circuit Analysis (WCCA/Monte Carlo), and Parts Stress/Derating analysis to guarantee high-reliability performance in space.
• Cross-Functional Collaboration: Partner directly with Flight Software, RF, Mechanical, and Thermal engineering teams to optimize system-level tradeoffs, board pinouts, and physical packaging.
• Manufacturing & Bring-Up: Collaborate with Contract Manufacturers (CMs) for DFM/DFA reviews, PCBA assembly oversight, rapid prototyping, and hands-on lab troubleshooting.
• Validation & Flight Qualification: Generate comprehensive technical drawings, specifications, test procedures, and reports; lead board-level and system-level environmental testing (thermal vacuum, vibration, EMI/EMC).

Basic Qualifications

• Education: Bachelor's degree in Electrical Engineering, Computer Engineering, or a related STEM field.
• Experience: 5+ years of hands-on experience in digital electrical design and hardware analysis.
• High-Speed Interfaces: Proven experience designing with high-speed digital interfaces (e.g., DDR4/DDR5, 1G/10G Ethernet, PCIe) and standard communication buses (CAN, RS-422/RS-485, SPI, I2C).
• SI/PI Analysis: 3+ years of hands-on experience using Signal and Power Integrity modeling tools (e.g., Ansys SIwave, HyperLynx).
• ECAD Proficiency: Advanced design experience with professional schematic capture and PCB layout tools (preferably Altium Designer).
• Space / High-Reliability Rigor: Demonstrated track record with Worst-Case Analysis (WCCA), parts stress evaluation, and derating.
• Lab Equipment Mastery: Deep proficiency with lab diagnostic tools (oscilloscopes, logic analyzers, spectrum analyzers, power supplies).
• U.S. Person Status: Must be a U.S. Citizen or Permanent Resident due to export control regulations (ITAR/EAR).

Preferred Qualifications

• Master's degree in Electrical Engineering or STEM field.
• Experience designing high-density FPGA or SoC processing systems for space or aerospace applications.
• Familiarity with industry space derating and design standards (e.g., EEE-INST-002, ECSS-Q-ST-30-11C, IPC-2221).
• Hands-on experience with circuit simulation software (LTSpice, SIMetrix/SIMPLIS).
• Knowledge of EMI/EMC/ESD design mitigations and testing protocols for space flight hardware.
• Scripting and test automation skills using Python or MATLAB.
• Ability and willingness to obtain and maintain a U.S. Government Top Secret Security Clearance.

Engineering Culture & Benefits

• Fast Iteration Cycles: In-house rapid prototyping and dedicated test lab access to validate designs quickly.
• Ownership & Autonomy: No silos, no politics-we encourage debate, make data-driven decisions fast, and commit together.
• Location Flexibility: On-site opportunity in either Mountain View, CA or San Diego, CA with relocation support available.

• We seek to create an environment where everyone can reach their full potential and drive outstanding results.
• This policy applies with regard to all aspects of one's employment, including hiring, transfer, promotion, compensation, eligibility for benefits, and termination.
• Offers will be contingent on the candidate's ability to access export-controlled information under U.S. law.
