Propulsion Engineer III

Applications will be accepted on an ongoing basis until the requisition is closed.

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We're working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight!

This role is part of the Blue Origin Engines business unit, where our focus is the design, development, manufacturing, and testing of engines and propulsion systems. Built for multiple uses, our family of engines is powering the next generation of rockets for commercial, civil, national security, and human spaceflight.

We are seeking a talented and motivated Mid-Level Fluid Controls Engineer to join our passionate engine fluid controls team - and we're specifically looking for someone with an eye toward growing into a project management leadership role. In this position, you will blend hands‑on technical ownership with meaningful cross‑functional coordination, giving you a powerful foundation to develop project management skills that will define the next phase of your career.

You will own valve component designs from concept through qualification, while also taking on increasing responsibility for coordinating development timelines, aligning cross‑functional stakeholders, and mentoring junior engineers. This role is intentionally structured to prepare high‑performing engineers for a project management career track within one of the most exciting aerospace companies in the world.

Components you may be responsible for include: solenoid valves, pneumatically actuated valves, check valves, cryogenic valves, and pressurized fluid systems.

Passion for our mission and vision is required.

• Own valve component and assembly designs from concept development through qualification, ensuring designs meet rigorous safety, reliability, and performance standards
• Apply strong fundamentals in propulsion, fluid mechanics, thermodynamics, and structural analysis to drive sound design decisions
• Examine non‑conforming hardware and develop effective technical resolutions in a timely manner
• Oversee component testing, both standalone and within engine hot fire test environments, ensuring compliance with design requirements and goals
• Utilize CAD tools and GD&T practices to develop precise, manufacturable hardware designs

• Coordinate development activities across program leaders, systems engineers, suppliers, and test groups to align on architecture selections and design solutions - serving as a key integration point across teams
• Manage project timelines and deliverables for assigned valve and mechanism development efforts, tracking progress against milestones and proactively identifying and mitigating schedule or technical risks
• Lead stakeholder communication by preparing and presenting design status updates, technical reviews, and project health reports to program leadership
• Collaborate with suppliers and vendors to manage component procurement, track deliverables, and resolve issues - building direct experience in vendor management and supply chain coordination
• Support design‑to‑production transitions
  , partnering with manufacturing and quality teams to ensure smooth handoffs and production readiness
• Define and refine best practices for engine valves and mechanisms, driving process improvements that increase team efficiency - a direct analogue to continuous improvement frameworks used in formal project management

• Mentor and guide junior engineers through…
