Mechanical Engineer - Advanced Manufacturing

H3X Technologies•Louisville, CO

5d•$90,000 - $200,000

About The Position

H3X is hiring Mechanical Engineers focused on advanced manufacturing across all levels (Associate to Staff) to develop and scale our manufacturing processes from early-stage prototypes through full production. You'll do hands-on process development and production support, bridging R&D and sustained manufacturing so new technologies can be built reliably, efficiently, and at scale. You'll take full ownership of a program or production area such as Stator Manufacturing, Rotating Assemblies, or Final Assembly, supporting both new product introductions and production scaling of existing products. Some positions lean more toward process development; others toward tooling, fixtures, and equipment.

Requirements

Degree in Mechanical Engineering or similar (or equivalent hands-on experience)
Strong grasp of engineering fundamentals, mechanical drawings, and GD&T
CAD proficiency, SolidWorks preferred
Bias to action, an ownership mentality, and a first-principles approach to problems
Excellent written and verbal communication, strong attention to detail, and high emotional intelligence: you collaborate respectfully and empathetically
Fundamentally curious and eager to learn quickly
Associate / early-career: You're a scrappy, hard-working self-starter who learns fast, runs toward problems, and would rather build and iterate than wait for perfect instructions. Internship, project, or team experience with real hardware is a plus.
Senior / Staff: You bring deep manufacturing experience scaling complex assemblies. Just as important, you build systems that save the team time rather than create overhead. You can walk a production area, identify which systemic improvements will actually move the needle, prioritize ruthlessly, and drive them to completion.

Nice To Haves

Experience scaling complex assemblies to higher production volume
Experience designing manufacturing floor layouts
Understanding of electric motors or high-voltage systems
Experience working in a startup environment
Experience with ISO9001 and/or AS9100 standards

Responsibilities

Develop, prototype, and mature novel manufacturing processes from concept through production deployment.
Lead manufacturing readiness for new products: process development, work instructions, tooling design, subscale testing, prototype builds, and the transition from prototype to production.
Own capacity planning and scalability for your production area; find the bottlenecks and implement the equipment, tooling, and workflow improvements that support forecasted demand.
Design, validate, and deploy production tooling, fixtures, and assembly aids in SolidWorks to improve quality, throughput, and operator ergonomics.
Resolve production issues through root-cause analysis and drive non-conformance investigations and CAPA to eliminate recurring defects.
Build the systems, tooling, and workflows that make the whole team faster: the goal is to save the team time, not add process for its own sake.
Partner with design, supply chain, quality, and operations to bake manufacturability into the product from the start.
