Head of Electrical & Avionics Engineering

Bothell, WA

Portal Space Systems is on a mission to expand humanity’s freedom of movement in space. We’re building the spacecraft that makes that mission possible. From our Bothell, WA headquarters, we design vehicles with the maneuverability, resilience, and adaptability needed for the next era of orbital operations. Every system we build is in service of a simple idea: space should be more accessible, responsive, and capable.

Joining Portal means stepping into a team that believes in bold engineering, fast iteration, and the power of small groups to change what’s possible. If you want your work to directly shape the future of in-space mobility, join us.

We are hiring aHead of Electrical & Avionics Engineering who will own Portal’s spacecraft electrical and avionics function including electrical architecture, power generation and distribution, RF/communications hardware, sensors, actuators, board-level electronics, avionics interfaces, and EMI/EMC technical ownership. This rolewill function astheauthority for electrical and avionics engineering as Portal scales.

You will work closely with Systems Engineering, Software/GNC/Autonomy, Systems Integration & Test, Vehicle Design, Build/Integration/Test, Propulsion, Flight Dynamics, and Chief Engineers to ensureelectricaland avionics designs support vehicle-level requirements, integration, verification, and mission closure.

Core Responsibilities

Electrical & Avionics Architecture

• Own spacecraft electrical and avionics architecture across vehicle programs, including power generation, energy storage interfaces, power distribution, command/data interfaces, RF/communications hardware, sensors, actuators, and avionics control interfaces.
• Define electrical architecture trades in partnership with Chief Engineers, Systems Engineering, Software/GNC/Autonomy, Flight Dynamics, Propulsion, and Vehicle Design.
• Own technical decisions for avionics hardware architecture, power management, board-level design, RF/communications interfaces, harnessing, and electrical integration boundaries.
• Establish electrical design standards, interface expectations, grounding/bonding approaches, EMI/EMC design practices, electrical margin philosophy, and hardware review expectations.
• Ensure avionics and electrical designs are compatible with vehicle-level configuration, integration flow, environmental test, acceptance test, and launch operations.

Power, RF, Boards, Sensors, and Interfaces

• Lead technical ownership of spacecraft EPS and power generation systems, including power budgets, distribution architecture, load management, battery/energy storage interfaces, and power behavior during mission-critical operations.
• Own RF and TT&C electrical hardware interfaces in coordination with Systems Engineering, Software/GNC/Autonomy, Flight Dynamics, and mission/customer stakeholders.
• Lead board design ownership, including schematics, layout coordination, component selection, bring-up, firmware-adjacent hardware interfaces, and production release support.
• Own sensor and actuator electrical interfaces, including signal integrity, compatibility with flight software and GNC needs, integration constraints, and verification approach.
• Define and mature harnessing, connector, grounding, shielding, and avionics enclosure requirements in partnership with Vehicle Design and Systems Integration & Test.

Verification, Integration, and Test Support

• Partner with Systems Engineering to define electrical and avionics verification methods, interface control documentation, test coverage, and requirement closure logic.
• Partner with Systems Integration & Test onflatsat, HITL, EGSE, hardware/software/mechanical bring-up, interface checkouts, integrated debug, and cross-functional defect triage. Your org model separates Systems Engineering as the control process owner from SIT as the integrated bring-up owner, so this role should feed both cleanly.
• Own electrical readiness for vehicle-level integration, power-on testing, board bring-up, RF checkout, harness continuity, electrical functional test, and EMI/EMC-related troubleshooting.
• Support anomaly investigations,…
