About Hextronics
Hex is building the infrastructure for on-demand aerial data. We design and manufacture drone-in-a-box systems that automate repetitive drone operations, taking humans out of the loop so the people who depend on aerial data can move faster. We're a small, agile team, we move fast, take on extreme ownership, and build products in months, not years.
The Role
As a Mechanical Engineer on the Hardware team at Hex, you’ll own critical parts of the large mechanical assemblies that make our dock products work, from actuators and pressure-formed enclosures to production readiness. You’ll design, prototype, and test complex mechanical components, drive DFA and DFM decisions, and ship hardware that operates unattended in the field. Most of our design work lives in Fusion 360.
The ideal candidate has operated in a high-tech, fast-paced environment, is comfortable driving across multiple stakeholders, and has a strong background in design, testing, validation, and scaling hardware to production
Responsibilities
Own critical mechanical subsystems on Hex’s new dock product. Including actuators, large enclosures, and actuator-driven assemblies
Design mechanical parts and assemblies in 3D CAD that meet structural, durability, manufacturability, and industrial design requirements
Drive design-for-assembly and design-for-manufacturing decisions on large mechanical parts produced via pressure forming, thermoforming, sheet metal, and injection molding
Develop and present multiple design solutions for novel challenges, articulating tradeoffs clearly to cross-functional teammates and documenting the design process thoroughly
Plan and execute verification and validation tests, leveraging DOE methodologies to deliver actionable insights on quality, performance, and manufacturability
Perform thorough root cause analyses to identify and resolve issues in the field and on the production floor
Collaborate with senior engineers to evaluate new technologies, materials, and manufacturing methods
Required Qualifications
Bachelor’s degree in Mechanical Engineering or related field
2 - 5 years of experience designing complex mechanical products. Ideally in robotics, industrial systems, consumer electronics, or aerospace
Strong proficiency with CAD software such as Fusion 360
Experience designing and manufacturing large mechanical parts: pressure forming, thermoforming, sheet metal, and/or injection molding
Hands-on experience with actuator selection and integration in real mechanical systems
Hands-on experience with rapid prototyping tools to build proof-of-concept models
Preferred Qualifications
Experience bringing a hardware product to market
Thermal analysis experience: CFD, FEA thermal, or hands-on thermal characterization of battery systems, electronics, or HVAC
Experience with cooling design and thermal management
Supported a product at large scale manufacturing
Working experience in a fast-paced or startup environment
Passion for robotics, autonomy, or aerial systems
Experience leading or working on an engineering competition team, i.e. Formula SAE, Baja SAE, RoboSub, Combat Robotics or similar
What We Offer
Competitive salary and equity
Comprehensive and highly subsidized medical, dental, and vision benefits for our team and their families
Write firmware that controls physical systems in the field
A small, technical team where your work ships and matters
