Job description

Sierra Space Careers:

At Sierra Space, we build the missions and systems that keep our world secure in the domain above Earth.

Sierra Space team members share a spirit of innovation and collaboration and a belief that we can deliver on the boldest missions in space today. Together with our customers, we aim to safeguard our nation, sustain human presence in space, and secure the freedom of operations in low Earth orbit and beyond.

Our success is measured by the trust of those who rely on what we build and deliver, and our technologies keep the United States and its allies mission‑ready throughout space.

We are mission‑driven, and together, we are an extraordinary team.

About the Role

The Systems Engineer II contributes to the development and implementation of advanced system solutions by providing alignment, connection and direction to the technical team throughout the product development lifecycle. The Systems Engineer II represents the viewpoint of the integrated whole during system development and works to glue segments and subsystems together via top‑down decomposition of stakeholder requirements, traceability through development artifacts, and bottom‑up validation and verification of the system. They help to shepherd the team through technical development milestones, track performance measures and identify technical risks to arrive at a compliant and cohesive system solution. The Systems Engineer II should have a firm grasp on Systems Engineering principles as they build expertise on specific systems engineering skills such as requirements management, system architecture development, concept of operation definition, system integration, and system verification, with an emphasis on Model Based Systems Engineering (MBSE) approaches and tools.
