Senior Fluidics Engineer – Assembly & Test

Blue Marble Space•Mountain View, CA

7d•Onsite

About The Position

Blue Marble Space is seeking a Senior Fluidics Engineer to assemble, integrate, and test flight-ready fluidic systems for biological payloads in spaceflight environments. This is a hands-on, execution-focused role with an emphasis on precision assembly under sterile conditions, including work in biosafety cabinets using aseptic technique. The ideal candidate brings deep experience with spaceflight hardware and thrives in a build-and-test environment, consistently delivering high-quality hardware without a primary focus on design ownership or team management. Experience aligned with environments such as NASA, SpaceX, or Blue Origin is strongly desired.

Requirements

Master’s degree or equivalent practical experience in Mechanical Engineering, Bioengineering, Chemical Engineering, or related field.
10+ years of hands-on experience with spaceflight hardware assembly, integration, and test.
Experience performing aseptic work in biosafety cabinets (BSCs).
Proven experience sterilizing fluidic components using autoclaving.
Strong understanding of contamination control and maintaining sterility through complex, multi-step processes.
Experience in fluid system testing (leak testing, flow measurement, pressure testing).
Ability to read and execute from engineering drawings, procedures, and build documentation.
High attention to detail and disciplined, repeatable execution.

Nice To Haves

Experience supporting multiple biological or life sciences payloads for spaceflight.
Familiarity with microfluidic systems.
Experience working in both cleanroom and biosafety cabinet environments.
Prior work with organizations such as NASA.

Responsibilities

Execute hands-on assembly of fluidic subsystems and biological payload hardware, including tubing, fittings, pumps, valves, and reservoirs.
Perform aseptic assembly within biosafety cabinets (BSCs) to maintain sterility of biological interfaces and reagents.
Apply and maintain strict sterile technique during installation of reagent systems, culture chambers, and fluid pathways.
Conduct leak checks, flow verification, priming, and functional testing without compromising sterility.
Operate and maintain fluidic test stands and sterile workspaces, ensuring readiness and compliance.
Perform sterilization of components and assemblies using autoclaving; organize hardware shipments for treatment by ethylene oxide (EtO), and e-beam irradiation.
Follow detailed work instructions and SOPs with high precision and consistency.
Document all assembly, sterilization, and test activities with full traceability.
Troubleshoot hardware and process issues during build and test, escalating design-related concerns appropriately.
Partner with engineering, biology, and quality teams to ensure hardware meets flight requirements.
