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.
