Company

hirify.global develops autonomous spacecraft, advanced payloads, mission software, and space-based interceptors for U.S. and allied space defense missions.

What you will do

• Own mass properties for flight vehicle structures and systems, including CG, MOI, POI, predictions, tracking, and growth allowances.
• Design mechanical components and support vehicle-level requirements for space-based interceptors, kill vehicles, and hypersonic flight systems.
• Define mass properties methodologies, reports, mechanical interface control documents, configuration baselines, and milestone deliverables.
• Develop and approve CG and MOI measurement test plans, witness testing, and resolve anomalies and non-conformances.
• Apply spacecraft and space-environment expertise to precision mechanisms, electronics packaging, seeker integration, vibration isolation, EMI management, and launch-load structures.
• Mentor junior mechanical engineers and communicate complex technical topics to executive, program, and customer audiences.

Requirements

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related discipline.
• 7–15+ years of professional experience in mechanical design and mass properties analysis, primarily on space-based interceptor, hypersonic, or similar high-performance flight programs.
• Expert proficiency in Siemens NX, complex multi-subsystem vehicle assemblies, configuration management, and part design.
• Expert knowledge of GD&T, custom datum and tolerance schemes, tolerance stack-ups, first-principles calculations, and flight vehicle structural design.
• Experience with rocket, missile, satellite, interceptor, kill vehicle, or re-entry system design from initial development through production, plus aerospace and defense standards such as MIL-SPEC, MIL-STD-810, MIL-STD-1540, and AIAA S-110.
• Ability to obtain and maintain a U.S. Secret or TS/SCI security clearance and meet ITAR eligibility requirements, including U.S. citizenship, lawful permanent residence, protected-individual status, or eligibility for required authorizations.

Nice to have

• Master’s degree or PhD in Mechanical Engineering, Aerospace Engineering, or a related discipline.
• 10+ years of interceptor, kill vehicle, or hypersonic flight vehicle experience with multiple programs delivered to flight test or operational fielding.
• Experience developing mass properties tracking tools, hypersonic aeroshells, TPS integration, precision seeker alignment, deployment or divert mechanisms, and ultra-mass-constrained structures.
• Familiarity with NASTRAN, Ansys, structural analysis, and FEA review.
• Experience with defense proposals and captures, or with scaling engineering teams and processes in a startup or high-growth aerospace and defense company.

Culture & Benefits

• Hybrid work environment with a mission focused on space superiority and defense aerospace.
• Equity participation and case-by-case compensation based on knowledge, skills, education, location, and experience.
• Health, dental, vision, HRA/HSA options, PTO, and paid holidays.
• 401(k) and parental leave.
