Electrical Engineer III, PCB Design & Avionics

About this position

Parallax Space is building critical mission infrastructure to enable rapid, reliable, and scalable access to space. We partner with commercial, civil, and national security customers to deliver high-performance satellite components, integrated payload systems, and mission capabilities that close critical gaps in modern space architecture.

Our model combines advanced engineering, mission execution, and scalable manufacturing to deliver high-TRL products and flight-ready systems at speed.

We are building the infrastructure backbone for the next generation of space systems.

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.

• 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

• 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
• 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

• 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

• 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

• 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…
