Build, architect, and maintain Vast’s high-performance computing infrastructure for aerospace engineering analysis. Responsibilities include cluster lifecycle management, patching, performance optimization, reliability, application and user onboarding, and integration with NX/Teamcenter design workflows. The role supports engineering teams using structural, mechanical, dynamic, and computational fluid dynamics analyses, while leading HPC initiatives from concept through production deployment.

Manages the Avionics and Power Systems Engineering team developing human-rated space station and satellite systems. Responsibilities include hiring and mentoring engineers, defining system architecture and fault management strategies, leading requirements decomposition, FMECA, verification and validation campaigns, configuration control, interface documentation, and integration and test activities. The role also drives technical decisions, milestone documentation, and cross-functional execution for complex aerospace programs.

Supports hands-on engine assembly, integration, testing, and transition from development to production. Creates assembly procedures, manufacturing plans, work instructions, and test plans; collaborates with design teams and technicians; resolves shop-floor blockers and nonconformances; procures tooling; and drives continuous improvement in aerospace engine manufacturing.

Lead end-to-end proposal development for high-power satellite bus opportunities supporting defense, intelligence, Space Force, and commercial customers. Own win strategies, schedules, compliance matrices, proposal volumes, color team reviews, and cross-functional coordination across engineering, business development, legal, contracts, finance, and leadership. Manage classified proposal efforts in SCIFs, support negotiations and awards, and improve proposal processes. The role requires extensive defense proposal experience, satellite mission systems knowledge, and TS/SCI clearance eligibility.

Develop spacecraft mechanisms from concept through flight, including motorized assemblies, linkages, spring and damper systems, rotating hardware, and crew-operated assemblies. Design, analyze, build, test, and iterate hardware while owning critical spacecraft systems. Collaborate with production teams, technicians, engineers, vendors, and managers to translate designs into flight hardware and support rapid prototyping, manufacturing, testing, and continuous improvement.

Designs, deploys, and maintains Linux workstations and servers. Develops Puppet configuration management, creates Ubuntu imaging processes, resolves Tier 2 and Tier 3 technical issues, supports hardware and software developers, and assists with infrastructure automation using Terraform. The role also contributes to identity and access management, patching, system security, documentation, and scalable workstation and infrastructure operations.

Supports aerospace hardware testing by fabricating, cleaning, activating, operating, troubleshooting, repairing, and maintaining pressurized ground support equipment and test articles. Executes development, acceptance, qualification, and investigative test campaigns; maintains laboratory and workshop infrastructure; interprets technical drawings and work instructions. Works with pneumatic, hydraulic, oxygen, refrigerant, vacuum, automation, control, and data acquisition systems supporting life-critical spacecraft hardware.

Develops and validates automated hardware-in-the-loop test systems for satellite and human-rated space-station avionics. Responsibilities include designing test assets, implementing system-level test cases, integrating and commissioning equipment, troubleshooting, leading design reviews, documenting systems, and mentoring engineers. Requires hardware test-system experience, Linux proficiency, electrical test equipment knowledge, root-cause analysis, and technical documentation skills. Preferred experience includes Python or C++, embedded systems, automated testing, space-system protocols, networks, CI/CD, and modular data-acquisition systems.
