Own thermal architecture, analysis, modeling, and validation for a high-power, constellation-ready spacecraft bus. Responsibilities include evaluating passive and active thermal-control approaches, sizing radiators, managing thermal budgets, selecting coatings and materials, planning TVAC campaigns, correlating models to test data, and supporting solar-array and avionics thermal design. The engineer will begin as the sole thermal specialist and build a team as spacecraft production scales.

Design and integrate rugged avionics enclosures, mounts, and brackets for human-rated space stations. Responsibilities include electronics packaging, interface documentation, requirements validation, thermal and structural analysis, engineering drawings, configuration management, hardware builds, and environmental qualification testing. The role collaborates closely with electrical engineering teams throughout the flight-critical product lifecycle and supports mission-critical testing and integration.

Guide the design, verification, validation, and reliability of thermal fluids, environmental control, and life support systems for Haven-1. Lead FMEA, fault-tree analysis, design reviews, risk mitigation, test planning, configuration management, and engineering standards. Partner with hardware, manufacturing, software, and risk teams to ensure human-rated systems meet design intent, reliability goals, and qualification requirements throughout development and integration.

Develop and optimize manufacturing processes for avionics systems and wiring harnesses. Create manufacturing plans, assembly procedures, and work instructions; resolve production issues through root cause analysis; collaborate with design, quality, and suppliers; perform hands-on assembly, integration, and testing; and drive continuous improvement in quality, efficiency, and cost.

Develop and optimize manufacturing processes for spacecraft solar arrays and avionics hardware. Responsibilities include design-for-manufacturing feedback, tooling and GSE development, assembly and testing, work instruction creation, supplier process review, root cause analysis, corrective actions, quality control, and continuous improvement. The role supports solar array environmental, deployment, and acceptance testing while collaborating with engineering, quality, suppliers, and technicians. It also includes mentoring colleagues and supporting new product introduction from prototype through production.

Supports structural and mechanisms testing for aerospace components, including test setup, instrumentation, data acquisition, troubleshooting, fixture design, and test procedure improvements. Operates hydraulic, pneumatic, and instrumentation systems; processes test data; maintains equipment calibration and preventive maintenance; and assists with lifting operations. The role independently executes tasks, resolves test issues, mentors technicians, and may lead small test teams. Requires onsite work in Long Beach, occasional travel to Mojave, overtime, elevated-height and outdoor work.

Partners with managers and functional leaders on organizational health, change leadership, talent management, performance management, compensation, employee relations, engagement, and team development. Provides HR guidance, uses people data to identify trends, maintains accurate HR systems, and improves scalable workflows. Supports a fast-growing, manufacturing-oriented workforce while reinforcing company values and may travel regularly between Vast locations.

Supports employee relations matters and workplace investigations from intake through resolution. Partners with managers, People Business Partners, Legal, and employees on policy guidance, conflict resolution, compliance, documentation, and corrective actions. Maintains confidential case files, analyzes trends, prepares reports and dashboards, supports policy updates and training, and helps mitigate organizational risk. Requires sound judgment, discretion, strong investigative and communication skills, and knowledge of federal and California employment laws.

Designs and builds automated RF test systems for component- and spacecraft-level applications. Develops test automation software, data processing, sequencing, and reporting; defines RF test requirements; and supports OTA, EMI/EMC, antenna pattern, and spacecraft system testing. Performs environmental testing including thermal cycling, TVAC, vibration, shock, and humidity, while supporting spacecraft integration in cleanroom facilities. Requires RF test experience, test equipment expertise, and software development skills.

Develop, test, maintain, and support full-stack web applications and backend services using frontend technologies, APIs, microservices, data modeling, and application pipelines. Participate in the full software development lifecycle, code reviews, debugging, incident resolution, and technical discussions. Collaborate with cross-functional teams to build scalable enterprise applications and improve engineering tools and practices.
