Mechanical Engineer III

Mechanical EngineerIII The Elevator Pitch What if the products you designed could help make some of the world’s busiest venues and public spacessafer,withoutcompromising the visitor experience? At Evolv,you’llhelp develop the mechanical systems behind technology used to protect communities around the world. As aMechanical Engineer III,you’lltake hands-on ownership of components and subassemblies throughout the product lifecycle—from early concepts and rapid prototypes through design validation, production tooling, release, and continuous improvement. Using SolidWorks and Arena PDM,you’llcreate reliable, manufacturable designs with a strong focus on plastic injection molding and integrated electromechanical systems. You’llwork closely with electrical engineering, firmware, industrial design, supply chain, quality, and manufacturing to solve complex design challenges and turn ideas into products that perform reliably in demanding, real-world environments. This is an opportunity to sharpen your technical craft, expand your ownership, and see your work deliver meaningful customer impact at scale. Success in the Role In the first90 days, you will: Build strong partnerships across mechanical engineering, electrical engineering, firmware, industrial design, supply chain, quality, and manufacturing while developing a solid understanding of Evolv’s products and development priorities. Become proficient in Evolv’s SolidWorks and Arena PDM workflows and contribute effectively to design reviews, documentation, and engineering-change processes. Take ownership of defined components, subassemblies, orsustaining-engineeringassignments and deliver high-quality designs, prototypes, drawings, or analyses with support from the broader team. In the first 12 months, you will: Independently owner mechanical design work for assigned product features, components, or sustaining initiatives from concept through validation and release. Deliver reliable, manufacturable, and serviceable designs that appropriately balance performance, cost, quality, and schedule. Drive product improvements byidentifyingroot causes and partnering across manufacturing, quality, and supplychainto implement well-documented design solutions. The Work Execute mechanical design and development for new and existing products, with anemphasis on injection-molded plastic components Create detailed 3D models, assemblies, and production-ready drawings in SolidWorks or an equivalent CAD system Translate product requirements into mechanical design specifications and contribute to design reviews and technical decisions Design precision electromechanical assemblies and enclosures, and manage the full product lifecycle from concept and prototyping through production tooling and sustainment Apply design for manufacturability and design for reliability principles to improve robustness, quality, yield, and long-term product performance Perform tolerance analysis, structural and thermal validation, and root-cause analysis on mechanical issues Collaborate with electrical engineering, firmware, industrial design, supply chain, quality, and manufacturing partners to ensure cohesive system integration Work directly with contract manufacturers and suppliers, includinginternationalpartners, to improve manufacturability and yield Support tooling, fixture, test-equipment design, prototype builds, factory validation, test plans, failure analysis, and design-transfer activities Manage andmaintainCAD data, bills of materials, engineering change orders, test plans, and other engineering documentation using Arena PDM Ensure compliance with Evolv quality-system and product-certification standards, including UL and CE requirements, and support risk assessments and DFMEA development Research emerging materials, manufacturing processes, and design methods; propose and prototype creative solutions that improve performance and cost efficiency Contribute to a collaborative, iterative engineering culture grounded in precision and curiosity Leadership, Team Structure & Culture You will join the R&D organization and report to the Director of Hardware Engineering. The organization fosters a collaborative, mission-driven culture that values trust, curiosity, kindness, and innovation.
