Responsibilities

As a Senior Satellite Systems Designer / Engineer focused on Payload Management, you will serve as a key technical leader responsible for coordinating, integrating, and managing payload-related engineering activities across a mission with multiple payload providers. You will act as the primary systems engineering interface between internal teams, external payload suppliers, customers, and satellite bus stakeholders to ensure payload requirements, interfaces, deliverables, test plans, and operational concepts are clearly defined, aligned, and executed.

• Lead payload systems engineering activities throughout the mission lifecycle, from concept through integration, test, launch, and commissioning.
• Serve as the primary technical interface between customers, payload suppliers, spacecraft engineering teams, and program stakeholders.
• Define, manage, and verify payload requirements, interfaces, and integration plans.
• Coordinate payload accommodation across mechanical, electrical, thermal, software, RF, and operational interfaces.
• Review payload documentation including requirements, interface control documents (ICDs), verification plans, test procedures, and operational concepts.
• Perform mission and systems analysis to assess payload impacts on spacecraft resources, including power, thermal, data handling, pointing, storage, and communications.
• Support payload integration, spacecraft-level testing, verification, anomaly resolution, and launch readiness activities in collaboration with AIT and V&V teams.
• Identify technical risks, resolve integration issues, and ensure alignment between customer expectations and spacecraft capabilities.
• Support payload commissioning and early mission operations as required.
• Mentor junior engineers and contribute to the continued development of payload systems engineering practices.

Requirements

• Bachelor's degree in Aerospace Engineering, Electrical Engineering, Systems Engineering, Physics, or a related technical discipline.
• 7+ years of experience in spacecraft systems engineering, payload engineering, mission systems engineering, or a related technical leadership role.
• Experience integrating or supporting spaceflight payloads or complex aerospace instrumentation.
• Experience defining and managing payload or subsystem requirements, interfaces, and verification activities.
• Strong understanding of spacecraft subsystem interactions, including mechanical, electrical, thermal, software, communications, and operational interfaces.
• Experience working directly with customers, suppliers, or external partners in a technical leadership role.
• Experience developing or reviewing engineering documentation such as requirements, ICDs, verification plans, CONOPS, or test procedures.
• Strong analytical and systems thinking skills with the ability to evaluate technical tradeoffs and resolve complex engineering challenges.
• Excellent written and verbal communication skills with the ability to work effectively across multidisciplinary teams.
• Demonstrated ability to leverage AI-assisted engineering and productivity tools to improve engineering efficiency and innovation.

Nice to Have

• Master's degree in Aerospace Engineering, Systems Engineering, Electrical Engineering, or a related field.
• Experience with one or more payload types, including optical, RF, communications, radar, remote sensing, or scientific instrumentation.
• Experience supporting spacecraft integration and test, environmental testing, or flight verification activities.
• Experience supporting spacecraft commissioning, LEOP, or mission operations.
• Familiarity with mission analysis and modeling tools such as Python, MATLAB, STK, or equivalent.
• Knowledge of industry systems engineering practices and standards (ECSS, NASA, INCOSE, or equivalent).

We Offer

• Competitive compensation with a robust equity plan to share in our success.
• Comprehensive coverage for health, dental, and vision insurance-including dependents.
• Unlimited vacation, supportive parental leave policy, and company-wide holiday shutdown.
• Semi-annual company-wide parties and frequent in-office team events.
• Relocation packages available for approved roles.
• $1,500 annual professional development fund to support your growth.
