Company

hirify.global is a defense technology company building precision robotic systems for the United States and its allies. Its Bullfrog product is an autonomous precision weapon system for counter-drone operations, supported by AI, computer vision, precision motion, and advanced hardware.

What you will do

• Build first-order physics and engineering models, including power budgets, SWaP budgets, and kill-chain timelines, before detailed design or hardware exists.
• Use model results to derive and allocate requirements, conduct design trade studies, support verification by analysis, and shape test plans.
• Grow models as designs mature and determine when additional model fidelity justifies its cost.
• Own analyses end to end by framing questions, stating assumptions, building models, and presenting results and sensitivities to engineering leads and customers.
• Work with hardware, software, and test engineers to anchor models to measured data and update them as test results become available.

Requirements

• BS in physics, engineering, applied mathematics, or a related quantitative field; MS or PhD preferred.
• Strong first-principles physics foundation in areas such as dynamics, heat transfer, and electrical power.
• 5+ years of experience building analysis models on hardware development programs.
• Proficiency in Python or MATLAB.
• The role can focus on software, mechanical/electrical hardware, or analysis; strong generalists are welcome.
• Ability to obtain a U.S. security clearance preferred.

Nice to have

• Experience with Simulink or other simulation tools.
• DoD program experience.
• Strong systems thinking and the ability to identify interface, assumption, and requirements risks.
• Experience turning ambiguous technical goals into structured requirements, verification plans, and closure criteria.
• Experience automating requirements traceability, verification tracking, data analysis, and evidence generation.
• Experience qualifying defense, aerospace, or safety-critical applications.
• Experience with requirements management in JAMA or DOORS.
• Technical rigor and sound judgment about the level of structure needed for fast-moving engineering programs.

Culture & Benefits

• Cross-functional collaboration across mechanical, electrical, software, controls, test, and operations teams.
• Full-time employment with competitive salary and an ACS equity package.
• Health, dental, and vision insurance.
• Paid time off.
• Equal employment opportunity workplace.
