Position Overview

Parallax Space is seeking a mid-level Electrical Engineer with a strong focus on PCB design to support the development of spacecraft electronics, payload electronics, avionics, test hardware, and mission-enabling electrical systems.

This role will contribute directly to the design, layout, build, test, and production transition of circuit boards and electrical assemblies used in high-reliability space systems. This role will work across schematic capture, component selection, PCB layout coordination, board bring-up, electrical testing, troubleshooting, design documentation, and cross-functional integration with mechanical, software, systems, manufacturing, and supply chain teams.

The ideal candidate brings hands-on PCB development experience, strong electrical engineering fundamentals, disciplined documentation habits, and the ability to move quickly while maintaining the rigor required for aerospace hardware.

Key Responsibilities

PCB Design & Electrical Development

• Design and support development of printed circuit boards for spacecraft, payload, avionics, power, communications, sensor, and test applications
• Develop schematics, select components, define interfaces, and support PCB layout for mixed-signal, digital, power, and high-reliability electronics
• Work with layout resources to define stackups, routing constraints, impedance control, power distribution, grounding, EMI/EMC considerations, and manufacturability requirements
• Support design decisions related to signal integrity, power integrity, thermal constraints, derating, reliability, and environmental performance
• Create and maintain design documentation including schematics, BOMs, interface control documents, assembly notes, design notes, and revision records

Board Bring-Up, Test & Troubleshooting

• Perform board bring-up, electrical checkout, functional testing, debugging, and failure analysis on prototype and production electronics
• Develop and execute test procedures for PCBs, cable harnesses, electrical assemblies, and integrated systems
• Use lab equipment including oscilloscopes, logic analyzers, spectrum analyzers, power supplies, electronic loads, multimeters, and environmental test equipment
• Identify root causes of electrical issues and drive corrective actions through design updates, process improvements, or supplier feedback
• Support verification and validation activities for flight hardware and engineering development units

Avionics, Payload & System Integration

• Collaborate with systems, software, mechanical, manufacturing, and mission teams to ensure electrical designs meet system-level requirements
• Support development of avionics interfaces, payload electronics, sensor electronics, power distribution, command/data handling, and ground support equipment
• Contribute to interface definition, connector selection, harness coordination, grounding schemes, and electrical integration planning
• Participate in design reviews, test readiness reviews, integration activities, and technical issue resolution

Manufacturing & Production Transition

• Support transition of PCB designs from prototype builds into repeatable production and flight-ready configurations
• Partner with manufacturing, suppliers, and contract manufacturers on DFM, DFA, DFT, assembly yield, inspection criteria, and process feedback
• Review fabrication and assembly outputs, resolve nonconformances, and support supplier technical communication
• Develop rework instructions, assembly guidance, test fixtures, and production support documentation as needed

Engineering Process & Documentation

• Maintain disciplined design records, revision control, BOM accuracy, requirements traceability, and engineering release documentation
• Support configuration management and engineering change control processes
• Contribute to requirements development, verification planning, risk tracking, and technical trade studies
• Help improve electrical engineering workflows, design standards, test practices, and reusable templates as the company scales

Qualifications

Required Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Aerospace Engineering, or related technical field
• 3-7 years of electrical engineering experience with direct PCB design, development, test, or production support responsibility
• Hands-on experience with schematic capture and PCB development using tools such as Altium Designer, Cadence Allegro/OrCAD, KiCad, or similar
• Experience supporting mixed-signal, digital, power, sensor, communications, or embedded electronics development
• Strong electrical troubleshooting and lab test skills, including use of common electronic test equipment
• Understanding of PCB layout fundamentals including grounding, power distribution, impedance control, EMI/EMC considerations, manufacturability, and testability
• Ability to read and create schematics, wiring diagrams, BOMs, test procedures, and engineering documentation
• Strong analytical, problem-solving, and communication skills
• Ability to work effectively in a fast-paced engineering and hardware development environment
• Eligibility to access ITAR/EAR-controlled information

Preferred Qualifications

• Experience designing electronics for aerospace, defense, spacecraft, launch, robotics, automotive, medical device, or other high-reliability hardware environments
• Experience with avionics, payload electronics, power electronics, RF interfaces, FPGA/SoC support circuitry, embedded systems, or sensor electronics
• Familiarity with IPC standards, PCB fabrication and assembly processes, and contract manufacturer coordination
• Experience with environmental testing, vibration testing, thermal vacuum, EMI/EMC testing, or qualification campaigns
• Experience with component derating, radiation considerations, fault tolerance, redundancy, or reliability analysis for space or defense applications
• Familiarity with PLM, configuration management, requirements management, and engineering release workflows
• Experience supporting government, DoD, NASA, SDA, or national security space programs
