Senior Mechanical Engineer (Structures)

Position Details
Location: Los Angeles (Hawthorne), CA
Employment Type: Full-time
Department: Starlight Solar
Travel: Occasional
The MissionStarpath develops and manufactures the technologies that will enable humans to live on the Moon and Mars. Today, we are building robotic systems that locally produce the essential commodities a lunar civilization will require at extreme scale: water, power, and oxygen. Our ultimate goal is to build and operate a self-sustaining city on Mars.
Senior Mechanical Engineer (Structures)The Starlight team is focused on dramatically improving space solar power to support Starpath’s core mission and the broader space economy. Starlight manufactures the lowest-cost, highest-performance space solar power systems, which will power the majority of new satellites built on Earth and all of Starpath’s equipment on the Moon and Mars.
As a Senior Mechanical Engineer on the Structures team, you will own the structural architecture, design, analysis, and qualification of Starlight’s solar array hardware. You will serve as a technical authority for lightweight space structures, resolving complex design and integration challenges from early trade studies through flight qualification and production.
Responsibilities
Own structural systems from architecture through detailed design, analysis, fabrication, qualification, and flight
Establish structural requirements, load cases, factors of safety, margin policies, and verification approaches
Lead architectural trades involving mass, stiffness, strength, reliability, manufacturability, cost, and system performance
Develop efficient load paths and lightweight primary and secondary structures, interfaces, brackets, housings, and mechanisms
Perform and review hand calculations and FEA covering stress, stiffness, buckling, fatigue, joints, thermal distortion, modal response, and dynamic environments
Develop and maintain structural models, loads documentation, margin summaries, and verification records
Own material, fastener, joint, finish, and manufacturing-process selections for the launch and space environments
Define structural qualification and acceptance-test programs covering static load, vibration, shock, and modal testing
Lead test-to-model correlation and use test results to improve both hardware and analytical models
Lead structural design reviews, failure investigations, risk-reduction efforts, and corrective actions
Work across thermal, avionics, mechanisms, controls, and systems teams to define interfaces and resolve coupled design challenges
Partner with manufacturing and suppliers to develop repeatable fabrication, inspection, assembly, and production processes
Identify structural risks early and create focused analysis or testing plans to retire them
Mentor engineers and establish sound structural design, analysis, documentation, and test practices
Drive mass reduction and design simplification without compromising structural integrity
Required Qualifications
Bachelor’s degree in mechanical engineering, aerospace engineering, structural engineering, or a related discipline
6+ years of professional mechanical-design or structural-engineering experience
Demonstrated ownership of complex structural hardware from concept through qualification or production
Strong command of structural mechanics, load paths, joints, stress, stiffness, buckling, fatigue, and structural dynamics
Proficiency with 3D CAD, GD&T, tolerance analysis, and detailed engineering drawings
Advanced experience performing and reviewing structural analysis using hand calculations and FEA
Experience defining structural test programs and correlating analytical models with test data
Hands-on experience building, testing, troubleshooting, and improving mechanical hardware
Ability to lead technical decisions, communicate risk clearly, and coordinate across engineering and manufacturing teams
Evidence of exceptional engineering ability
Preferred Qualifications
Advanced degree in mechanical engineering, aerospace engineering, structural engineering, or a related discipline
Experience owning structures that have survived launch and operated in space
Advanced proficiency with Nastran, Abaqus, Ansys, Femap, or similar FEA tools
Experience with quasi-static loads, random vibration, shock response, modal analysis, thermal distortion, fatigue, and coupled-loads analysis
Experience leading static load, vibration, shock, and modal qualification campaigns
Expertise in test planning, instrumentation, data interpretation, and test-to-model correlation
Experience designing lightweight structures across machined, sheet-metal, welded, composite, and bonded construction
Deep knowledge of aerospace materials, fasteners, joint design, and structural margin policies
Experience with deployable structures, hinges, latches, actuators, or other spacecraft mechanisms
Familiarity with NASA-STD-5001, GEVS, and other applicable aerospace structural standards
Experience transitioning flight hardware from prototype development into repeatable production
