Tooling Engineer

Colossus Search is looking for a Tooling Engineer with 3-5+ years of experience to design and develop large-scale, safety-critical tooling for solid rocket motor production at a fast-growing hypersonics company. You'll be responsible for figuring out how to safely move, handle, and process thousands of pounds of energetic materials designing fixtures, assemblies, and environmental systems that keep explosive precursor chemicals at the right temperature and in motion.

This is a high-stakes, hands-on role where your engineering fundamentals and ability to work at scale with dangerous materials will directly enable delivery of the first 50 units to the U.S. Navy.

• What will you be doing?
• Designing and developing large-scale tooling (jigs, fixtures, molds, and handling assemblies) for safely moving and processing 600+ gallon, 2,000+ lb batches of ammonium perchlorate and aluminum oxidizer precursor chemicals
• Engineering solutions for temperature control, material movement between buildings, and safe breakdown of explosive materials into smaller quantities for solid rocket motor casting
• Collaborating cross-functionally with manufacturing, design, and production teams to architect tooling that meets aggressive cost, quality, and delivery targets for first-build production
• Leading tooling projects end-to-end from concept through production floor implementation, including FEA validation, tolerance stack-ups, and DFM principles
• Mentoring junior tooling engineers and technicians while ensuring compliance with aerospace and defense industry standards

• 3 - 10 years of experience in tooling design for large-scale, heavy, or hazardous hardware

• Tech stack CAD (Solid Works/NX/CATIA), FEA, GD&T, Tolerance Stack-Up Analysis
• Tech stack CAD (Solid Works/NX/CATIA), FEA, GD&T, Tolerance Stack-Up Analysis

Not specified.

• Salary $140K - $200K ($140K - $200K base salary + competitive equity. Range may flex higher for exceptional candidates with relevant experience in large-scale, safety-critical tooling environments.)
