Develop performant Julia-based 6DOF Software-in-the-Loop simulation code for aerospace systems. Build scalable Monte Carlo simulations and physics-informed models, collaborate with flight software, HMI, and flight sciences teams, validate models against real flight data, optimize real-time performance, participate in testing and code reviews, and document modeling assumptions and validation workflows.

Supports development of flight-critical propulsion components such as valves, actuators, and fluid-control hardware from clean-sheet design through production. Responsibilities include engineering trade studies, analysis, integration, build-test-iterate cycles, troubleshooting, root-cause analysis, qualification, reliability and safety evaluation, and transition to production-ready designs. The intern collaborates with propulsion and vehicle teams in hands-on, fast-paced build and test environments.

Supports direct-materials purchasing, supplier gap analysis, approved supplier list development, supply chain SOP documentation, standard parts inventory planning, supplier audit and business review frameworks, and production-readiness process improvements. Collaborates with engineering, manufacturing, and quality teams to align sourcing strategies with vehicle production goals.

Supports the design, manufacture, operation, and maintenance of test assets for supersonic vehicle subsystems. Responsibilities include designing fixtures and tooling, creating CAD models and drawings, developing test plans, performing engineering analysis, troubleshooting fluid, mechanical, and electrical systems, collecting test data, documenting results, and collaborating with manufacturing and engineering teams to improve testing capabilities.

Assist in designing, developing, and testing propulsion components and systems. Collaborate with teams to produce hardware and document testing activities.

Own the monthly and quarterly close, consolidated financial reporting, technical accounting, cost accounting, inventory valuation, and standard costing. Research US GAAP positions, support audits and internal controls, improve accounting processes through automation, and provide analyses for company-wide decisions. The role partners with the Controller, FP&A, Operations, and external auditors in a fast-paced manufacturing startup environment.

Develop modern C++ flight-autonomy software for supersonic unmanned aircraft, including guidance, navigation, control loops, mission autonomy, sensor integration, and vehicle decision-making. Integrate capabilities with aircraft, command-and-control, communications, and operator systems. Build testing and simulation tools, diagnose cross-functional issues, and support software-, hardware-, ground-, and flight-testing while owning technical problems through operational deployment.

Integrate capabilities with aircraft, command-and-control, ground, and operator systems. Build tests and simulations, diagnose cross-functional problems, and support software-in-the-loop, hardware-in-the-loop, ground, and flight testing while collaborating with GNC, simulation, operations, and pilots.

Design, build, test, and integrate aerospace flight hardware while transitioning prototypes into production. The role leads hardware delivery, detailed design, material selection, DFM, tooling, factory and test-flow development, vehicle assembly, flight-hardware testing, and process simplification. It requires close collaboration across engineering, manufacturing, production, and test teams, with travel to test sites and partner locations up to 25% of the time.

Designs and analyzes aircraft structures supporting hydraulics, fuel, propulsion, and avionics systems. Performs structural and thermal calculations, FEA, and subsystem trade studies. Owns hardware development from concept through fabrication, integration, and testing while collaborating with manufacturing, supply chain, test, suppliers, and customers. The role requires hands-on prototyping, mechanical assembly, CAD, PLM, and testing under vibration, fatigue, shock, vacuum, and thermal conditions.

The Build Engineer will plan projects, collaborate on design, lead hardware delivery, and run test procedures for flight hardware in a high-speed aircraft manufacturing setting.

Manage the maintenance, refurbishment, and overhaul of F100 engines, collaborating with engineers and technicians to ensure high-quality propulsion system performance.

Serve as legal partner for subcontracts and supply chain: draft, review, and negotiate high-volume supplier agreements; ensure FAR/DFARS/OTA flowdowns and export control compliance; build playbooks, templates, and SOPs; support programs, trade compliance, dispute resolution, and leadership with pragmatic risk analysis.

Design and develop complex aerospace mechanisms and mechanical systems for high-speed aircraft. Perform stress, fatigue, kinematics, FEA, and simulation analyses; oversee prototyping and testing; select materials and manufacturing processes; collaborate with suppliers and cross-functional teams; document designs and test results; mentor junior engineers; and contribute to aerospace research and development.

Develop and maintain embedded flight software for aircraft flight control, navigation, communication, and avionics systems. Collaborate with hardware and systems engineers on integration, requirements, design, testing, simulations, debugging, and safety-critical software documentation. Participate in code and design reviews while ensuring performance, quality, and regulatory compliance.
