Company

hirify.global develops hardware that powers ocean sensing networks at the intersection of ocean science, climate, and technology.

What you will do

• Own mechanical designs and subassemblies from early concepts and 3D CAD through prototyping, validation, and production.
• Design reliable hardware for harsh marine environments while balancing performance, manufacturability, cost, and schedule.
• Build, test, debug, and iterate on prototypes and production hardware using testing and failure analysis.
• Lead mechanical design reviews and collaborate with electrical, firmware, software, and manufacturing engineers on integrated systems.
• Work with suppliers, machine shops, vendors, and contract manufacturers to develop and scale parts and assemblies.
• Support marine sensing applications, customer collaboration, field testing, and ocean deployments.

Requirements

• 5+ years of professional mechanical engineering experience designing hardware for marine, robotics, aerospace, automotive, or other demanding environments.
• Strong proficiency in 3D CAD, preferably Onshape or SolidWorks, with experience owning designs from concept through production.
• Strong fundamentals in materials and process selection, structural analysis, fatigue, tolerancing, GD&T, and engineering drawings.
• Experience building, testing, debugging, and iterating on physical hardware.
• Strong engineering judgment and effective collaboration across electrical, firmware, manufacturing, and external vendor teams.
• Visa sponsorship is available, although sponsorship cannot be guaranteed for every role or situation.

Nice to have

• Experience designing hardware for marine or subsea environments, including sealing, corrosion, and long-duration environmental exposure.
• Experience with FEA and static, cyclic, impact, or thermal loads.
• Experience integrating sensors into larger systems.
• Hands-on machining or fabrication experience.
• Previous startup experience and a connection to the ocean.

Culture & Benefits

• Work on consequential problems spanning ocean science, climate, and technology.
• Collaborate in a small, fast-moving engineering environment.
• Use AI tools for research, preparation, and selected work activities, with hiring decisions made by people.
• Immigration lawyer support is provided for visa sponsorship processes.

Hiring process

• Applicants should submit their own initial application draft; AI may be used for refinement and polishing.
