Position Status: Contingent Upon Program Award

As a Senior Systems Engineer, you will be a technical leader contributing across multiple satellite and space-system programs. You will help deliver critical subsystems, system-level work packages, verification campaigns, and technical deliverables that roll up into larger missions.

You will draw on experience across multiple lifecycle phases, including requirements definition, architecture development, design, integration, verification, commissioning, and operations. The role requires the ability to quickly integrate into new projects, establish technical clarity, and lead engineering execution in areas where requirements, interfaces, risks, and trade-offs must be actively managed.

You will act as a bridge between disciplines, ensuring that requirements are understood, interfaces are controlled, risks are visible, and technical decisions are made with appropriate consideration for mission performance, cost, schedule, reliability, and operational needs. Success in this role comes from the ability to apply systems engineering judgment, right-size processes to the maturity of the work, and keep teams aligned on delivery.

This role is suited for an experienced systems engineer who can operate with autonomy, mentor junior and intermediate engineers, communicate effectively with internal and external stakeholders, and deliver high-impact technical outcomes across a multi-program environment.

Key Responsibilities

Coordinate with subsystem teams across payload, RF , avionics, software, mechanical, thermal, ADCS / GNC , ground systems, and mission operations to support integration and resolve interface questions

-

Maintain key engineering documentation, including requirements, ICDs, VCDs, technical budgets, analysis reports, CONOPS inputs, review packages, and decision records

-

Support verification, integration, test, commissioning, and operational readiness activities by preparing technical inputs, tracking evidence, and supporting closure of assigned requirements

-

Support troubleshooting, anomaly investigation, and root cause analysis using test results, telemetry, data products, and interface performance information

-

Participate in technical discussions with internal teams, suppliers, customers, and external stakeholders, with support from senior engineers as required

-

Contribute to proposals, feasibility studies, early mission concepts, and new business initiatives by preparing analysis inputs, assumptions, and supporting documentation

-

Apply systems engineering best practices with increasing autonomy and use analysis tools, scripting, automation, and AI-enabled tools to improve engineering efficiency.
