Develops reliable full-stack software and mission-critical applications supporting SpaceX launch, manufacturing, Starlink, and operational systems. Responsibilities include designing architectures, building prototypes, improving user workflows, owning software and product development, participating in code reviews, and optimizing application performance, testing, deployment, and monitoring. The role is fully onsite and may require extended hours or weekends based on launch schedules.

Manage sourcing, purchasing, supplier performance, forecasting, and fulfillment for precision-machined parts, raw materials, and complex manufactured components. Negotiate quotes, issue purchase orders, interpret engineering specifications, coordinate design changes, and ensure supply continuity. The role requires collaboration across engineering, suppliers, and internal stakeholders, along with experience in manufacturing processes, ERP/MRP systems, demand planning, and data analysis.

Leads a cybersecurity engineering team responsible for defending the Starshield network against active threats. Implements cyber defense strategies, conducts red-team exercises and vulnerability hunts, improves incident detection and response, and develops countermeasures across large-scale systems. Collaborates with security feature, monitoring, and engineering teams while remaining hands-on with software and security challenges.

Designs, deploys, troubleshoots, monitors, and maintains enterprise wireless networks across SpaceX sites. Responsibilities include access point placement, wireless surveys, coverage remediation, hardware and software updates, inventory management, network monitoring, and documentation. The role collaborates with infrastructure teams and may involve travel, physical work, outdoor environments, elevated heights, and passing an Air Force background check.

Assesses internal applicants, evaluates skills against job requirements, identifies alternative career opportunities, and supports hiring managers through interview debriefs and decisions. The role owns internal candidate relationships, communicates feedback, manages applicant dispositions, develops job postings, and creates recruiting-HR processes. It requires onsite work, occasional extended hours and weekends, and compliance with ITAR eligibility requirements.

Perform month-, quarter-, and year-end close activities, journal entries, reconciliations, and variance analysis. Support inventory, fixed assets, and cost accounting. Collaborate with Tax, FP&A, Financial Reporting, and auditors. Ensure US GAAP compliance, drive process improvements and automation, and perform ad hoc financial analyses.

Develop and own reliable internal applications used across SpaceX, including manufacturing, launch, Starlink, and data systems. Responsibilities include designing software, building prototypes, solving user problems, contributing to architecture and code reviews, and managing testing, deployment, monitoring, and performance. The role requires full-stack development and onsite work, with possible extended hours based on launch schedules.

Performs structural dynamics, vibration, acoustics, and system-level analyses for Falcon launch vehicles and Dragon spacecraft. Responsibilities include resolving dynamics problems through analysis and testing, monitoring vehicle and engine performance using flight data, planning and executing dynamic tests, processing signals, correlating models, driving hardware or operational changes, and developing analytical software. The role requires engineering fundamentals, structural dynamics experience, programming, and finite element modeling expertise.

Design and implement satellite GNC software, conduct high-fidelity modeling and simulations, and validate flight performance through rigorous testing, ultimately ensuring mission success for Starshield satellites.
