Senior Test Engineer

About the role

This role designs, operates, and advances test infrastructure to validate jet engines and subsystems for supersonic hardware research. It ensures each design is rigorously verified for quality and performance before aircraft integration using a test-like-you-fly approach. The position supports critical programs for a vertically integrated aerospace company developing high-speed, on-demand global mobility.

Software engineers turn product ideas into working code. Engineers work in small teams, review each other's work, and ship in small batches. Most teams follow agile practices such as sprints and daily standups. Engineers also write tests, fix bugs, and improve performance. The field values clear communication as much as technical skill. Engineers spend part of every week on planning, code review, and debugging, not just writing new code. The ability to explain a technical decision in plain words separates strong engineers from the rest.

Key facts

What you'll do

Test facility uptime and cleanliness are maintained through troubleshooting, maintenance, and strict attention to site organization. Data and video recording infrastructure is implemented to capture test events and system responses. Equipment activation, calibration, and operation are verified through systematic data analysis. Stand problems are diagnosed quickly, and corrective actions reduce downtime and sustain throughput. Test throughput and reliability are increased as facility capabilities are continually improved for advancing test programs. Assembly tasks, including crimping and soldering terminals, cable lacing, and troubleshooting, prepare test interfaces. Manual machine shop equipment, such as drills, cutting tools, mills, and lathes, is used to build or modify test fixtures and parts.

Requirements

Hands-on experience with fluidic and mechanical systems and test operations spans 5+ years in demanding environments. Experience with hazardous settings, including flammables, high voltage, and pressurized systems, includes consistent application of safety mitigations. Knowledge of fluid systems hardware and instrumentation covers pressure, temperature, load cells, relays, solenoids, and pneumatics. Familiarity with data acquisition and control systems, PLC hardware, computer networking, and software interfaces enables integration of test setups. Proficiency with PLC and data processing software, including Python, MATLAB, and LabVIEW, is used for configuring and analyzing tests. Initiative drives continuous improvement, expanding responsibilities beyond assigned tasks to optimize processes. Adaptability supports work in a fast-paced environment as test campaigns evolve. Detail-oriented behavior maintains a high level of quality to ensure test results are accurate and repeatable.

Practical notes

The role requires US work authorization and a Bachelor's degree. You will work onsite five days a week at the San Francisco location. Typical interview steps

Hiring for engineering roles usually starts with a recruiter screen, followed by one or two technical rounds. Candidates often solve a coding problem, discuss past projects, and answer system design questions. Some loops include a take-home task. Final rounds typically cover team fit and give candidates a chance to ask questions. Interviewers look for how you break down an unfamiliar problem, not just whether you reach the answer. Practicing a few problems aloud and reviewing your own past projects are the best preparation.

Good to know

Roles in aerospace test engineering often combine hardware integration, data systems, and safety discipline. Familiarity with propulsion test cells and data acquisition platforms supports rapid onboarding. Fluency in engineering tools and scripting helps manage repetitive test workflows. Clear documentation and precise measurement practices underpin reliable test programs. Collaboration across mechanical, electrical, and software teams is common in integrated test environments.

Career growth

Engineering careers usually progress from individual contributor to senior, staff, and principal levels. Some engineers move into management and lead teams of five to twenty people. Others stay on the technical track. Growth follows demonstrated impact, not tenure alone. A typical engineering ladder has clear levels with defined expectations for scope, quality, and mentorship. Moving up usually requires owning outcomes end to end rather than completing assigned tickets.
