What they're building

Airframe manufacturing operation and aircraft factory strong signal

Today: Site: "The world's first jet engine that's engineered for efficiency across subsonic and supersonic speeds."

Roles: Airframe Manufacturing Engineer · Composites and Airframe Build Lead · Senior Build Engineer, Airframe Composites Manufacturing · Senior Tooling Design Engineer, Airframe Manufacturing

Requirements mention: aircraft manufacturing line · airframe manufacturing operations · composite fabrication · large assembly fixtures

Inference: the company is setting up its own airframe production line from scratch in San Francisco; four of the seven Manufacturing roles are airframe build and tooling roles.

Clean-sheet autonomous aircraft: airframe design and flight software strong signal

Today: Site: "The world's first jet engine that's engineered for efficiency across subsonic and supersonic speeds."

Roles: Lead Structures Engineer · Mechanical Systems Design Engineer · Senior Aerodynamics Engineer · Mechanical Engineer, Fluid Systems · Software Engineer, Engineering Applications · GNC Software Engineer (Mid-Level to Senior) · Senior Flight Software Engineer · Flight Software Engineer

Requirements mention: aircraft structures · composite structural design · experimental flight testing · 6-DOF dynamics and simulation models · autonomous software systems

Inference: beyond the engine, the company is designing its own aircraft. Postings describe a demonstrator aircraft and a clean-sheet autonomous aircraft, with open roles in structures, aerodynamics, fluid systems and flight software.

Duality™ jet engine development and test infrastructure strong signal

Today: Site: "The world's first jet engine that's engineered for efficiency across subsonic and supersonic speeds."

Roles: Senior Propulsion Design Engineer · Senior Mechanical Design Engineer · Senior Test Engineer · Senior Propulsion Test Engineer · Senior Test Design Engineer · Test Design Engineer II

Requirements mention: turbomachinery · test stand design and documentation · test stands · data acquisition and control systems

Inference: the company is taking its jet engine (named Duality™ in one posting) toward flight. One propulsion posting covers hardware from early prototype through flight qualification and vehicle integration. Four Testing roles, two in San Francisco and two in East Bay Area, build and run the engine test stands.

In-house engine repair station and engine inspection moderate signal

Today: Site: "The world's first jet engine that's engineered for efficiency across subsonic and supersonic speeds."

Roles: A&P Mechanic · Aircraft Mechanic

Requirements mention: 14 CFR Part 145 class 3 powerplant rating · FAA Inspection Authorization (IA) · engine inspection · major repairs and alterations

Inference: the company is building its own engine inspection and alteration capability. Both postings describe an engine repair station built from the ground up and ask for experience on IAE V2500 and GE CFM56 turbofans.

Ground power generation product moderate signal

Today: Site: "The world's first jet engine that's engineered for efficiency across subsonic and supersonic speeds." (ground power appears in postings, not on the site)

Roles: Principal Electrical Engineer, Power Systems · Senior Electrical Engineer, Power Systems

Requirements mention: medium-voltage systems (1–38 kV) · generator control systems · paralleling/grid-interconnect schemes

Inference: the company is developing a ground power product. One posting describes a 13 MW aeroderivative generator for data centers and industrial sites waiting on grid capacity. The other says the product repurposes aircraft engines and accelerates development of the aircraft product.

Military applications of the aircraft weak signal

Today: Posting (Chief Engineer, Defense): "applications of our aircraft in direct support of the military."

Roles: Chief Engineer, Defense

Requirements mention: defense acquisition processes · government customers

No inference drawn: one role in the Defense Systems department is the only evidence.

Of 32 open roles, the largest departments are Manufacturing (7), Airframe (5) and Testing (4), and 29 of the 32 roles are in San Francisco.

Who they need

Seniority: Mostly senior: 16 senior, 7 mid, 3 director, 2 junior, 1 principal, 1 staff and 1 unknown (these labels cover 31 of the 32 roles).

Skills named most: engineering drawings, power electronics, Python, electrical schematics, jet engine, GD&T, manufacturing processes, test procedures, P&ID, CAD, NX, C++

Locations: San Francisco (29 roles), East Bay Area (2 roles), San Francisco - Remote (1 role, Director of Marketing).

How to use this

If you're applying: Apply if your background matches the Manufacturing, Airframe, Propulsion, Testing or Software roles listed above, and check the hard requirements in the fit lines before applying. Ten roles opened in the last 30 days and 15 in the 30 days before that, while 2 closed. 'Slowing' means fewer new postings, not a net reduction.

If you're selling or recruiting: Call about the airframe factory build-out and the aircraft design team: Manufacturing (7) and Airframe (5) together hold 12 of the 32 open roles, almost all in San Francisco. Engine test (4 Testing roles, two in East Bay Area) is a second thread. The Ground Power and Defense Systems roles are separate conversations. The company's posted team size is not in the data, so do not quote one.
