What is the difference between Spacecraft Power System Engineer vs Satellite Systems Engineer?

AspectSpacecraft Power System EngineerSatellite Systems Engineer
Required CredentialsBachelor's or Master's in Electrical Engineering, Power Systems specializationBachelor's or Master's in Electrical, Aerospace, or Systems Engineering
Work EnvironmentDesigning, testing, and integrating power systems for spacecraft in labs and cleanroomsDeveloping and managing satellite systems, including power, in engineering offices and labs
Industry UsagePrimarily in aerospace, space agencies, and defense contractorsIn satellite manufacturing, aerospace companies, and space agencies

While both roles focus on electrical systems within space technology, the Spacecraft Power System Engineer specializes in designing and managing power systems specifically for spacecraft, whereas the Satellite Systems Engineer covers broader satellite systems, including communication, payload, and power. The former is more focused on power subsystem integration, while the latter oversees entire satellite operations.

Key responsibilities

  • Architect and design spacecraft power systems including solar array interfaces, battery regulation, power distribution units, and grounding schemes.

  • Lead development of the main spacecraft power bus, including voltage regulation, load management, protection, and redundancy strategies.

  • Drive hardware bring-up, functional testing, and fault isolation on power boards and integrated systems.

Job description

We are seeking a Senior Electrical Engineer with deep expertise in hardware electrical design for spacecraft, particularly in power systems engineering and bus-level power management. Responsibilities
  • Architect and design spacecraft power systems including solar array interfaces, battery charge/discharge regulation, power distribution units (PDUs), and system-level grounding schemes.
  • Lead development of the main spacecraft power bus: voltage regulation, load management, protection, and redundancy strategies.
  • Perform trade studies and system sizing for battery capacity, solar array performance, and bus architecture optimization.
  • Develop schematics, PCB layouts, and cable harnessing for power boards and interface hardware.
  • Drive hardware bring-up, functional testing, and fault isolation on power boards and integrated systems.
  • Collaborate with systems, mechanical, and thermal engineers to align EPS design with mission requirements and spacecraft constraints.
  • Contribute to environmental testing for acceptance and qualification and EMI/EMC compliance for power hardware.
  • Coordinate with Launch Providers on interfaces and concept of operations during payload integration, launch pad and waking up in space.
Basic Qualifications
  • B.S. or M.S. in Electrical Engineering or related field.
  • 5+ years of experience designing power systems for aerospace, spacecraft, or other high‑reliability platforms.
  • Strong understanding of power electronics design, including DC‑DC converters, battery management systems, and overcurrent/undervoltage protection circuits.
  • Proficiency with ECAD tools (e.g., Altium Designer) for board design and system schematics.
  • Hands‑on experience testing and debugging flight or flight‑like power hardware in lab and system testbeds.
Preferred skills & Experience
  • Experience with spacecraft power architectures including unregulated and regulated bus designs.
  • Knowledge of space‑grade components, derating guidelines, and radiation effects on power electronics.
  • Familiarity with power system modeling and analysis tools (e.g., PLECS, SPICE).
  • Experience with EPS integration and operations on actual flight programs.
  • Familiarity with standards such as NASA‑STD‑4005, ECSS‑E‑ST‑20‑20, or NASA power interface specs.
Compensation & Benefits

Base salary is just one part of your total rewards package at Portal. You may also be eligible for long‑term incentives in the form of company stock, stock options, or long‑term cash awards, as well as potential discretionary bonuses and the ability to purchase additional stock at a discount through an Employee Stock Purchase Plan. You will also receive access to comprehensive medical, vision, and dental coverage. Portal is planning to establish future access to a 401(k) retirement plan, short & long‑term disability insurance, life insurance, and various other discounts and perks. Employees typically have 2‑3 weeks of paid vacation per year plus company holidays.
