Deep Trekker, a proud member of the Halma companies, is the leading technology platform making complex underwater missions easier than ever before! Our above-ground and underwater remotely operated vehicles (ROVs) are used across the world across a variety of applications and users, and we're constantly pushing the next frontier of technology while keeping our designs simple and robust for our customers. Our teams are expanding, and we are currently seeking a versatile and talented Mechanical Designer to join our growing organization. If you have a passion for robot design and innovation, and you want to build your career with a company that builds robots, this role might be for you.
About the Role Do you love owning a design from a blank sheet to a product that ships? We're looking for a Mechanical Designer to take a subassembly or product through the full lifecycle — concept, design, prototyping, testing, production release, and sustaining engineering. You'll work in SolidWorks daily, design for the realities of marine and harsh-environment use, and partner closely with electrical engineering, manufacturing, and suppliers to get a reliable, manufacturable design out the door. If you like being hands-on with what you design and seeing it through to production, we'd love to hear from you.
Who You Are Before anything else, we're looking for someone who brings the right mindset to the team:
Be helpful — Work closely with electrical engineers, manufacturing, and suppliers, and bring a collaborative attitude to design reviews.
Be reliable — Own your subassembly or product end to end, and keep BOMs, ECNs, and documentation accurate and up to date.
Be gritty — Stay steady when a build/test issue crops up or a design needs another pass to get right.
Be curious — Dig into sealing systems, material choices, and manufacturability the way a puzzle deserves, not just to check a box.
Be proactive — Spot a cost, reliability,



or manufacturability improvement and drive it forward before being asked.
Be a good person — Act with empathy and respect to build trust and positive energy across the team.
These traits matter as much as technical skill — we can teach the tools, but this mindset is what makes someone great at this job.
What You'll Do Design & CAD Create and maintain 3D models, assemblies, and detailed drawings in SolidWorks for mechanical components
Design for manufacturability (DFM) and assembly (DFA)
Select materials and finishes appropriate for marine/subsea or harsh-workplace use
Design and specify sealing systems (O-rings, gaskets, potting) for waterproof/pressure housings
Translate requirements/specifications into design concepts and detailed designs
BOMs & Documentation Create, structure, and maintain multi-level BOMs (mechanical, and coordinating with electrical/harness BOMs)
Manage BOM revisions and configurations across product variants
Ensure BOM accuracy between CAD, ERP, and manufacturing documentation
Product Ownership & Project Management Own a subassembly or product from concept through design, prototyping, testing, production release, and sustaining engineering
Support design reviews (PDR, CDR) and stage-gate milestones
Track and report on project schedule/status for owned scope
Build, Test & Cross-Functional Collaboration Assemble and integrate prototype and production units
Troubleshoot design or assembly issues found during build/test and drive corrective actions
Work closely with electrical engineers on mechanical-electrical integration




Interface with manufacturing/production teams to resolve build issues and improve processes
Source and communicate with suppliers
Identify and implement design improvements for cost reduction, reliability, or manufacturability
Basic Qualifications 3–5+ years of mechanical design experience
Expertise in SolidWorks for both 3D modeling and 2D drafting
Experience creating and managing multi-level BOMs
Demonstrated ownership of a product or subassembly through a full NPD lifecycle — concept through production release
What You'll Need Experience participating in formal ECN processes
Physical, hands-on experience building, assembling, and testing mechanical prototypes and/or production units
Ability to manage multiple projects/subassemblies simultaneously with minimal oversight
Strong written and verbal communication skills for design reviews and cross-functional collaboration
Strong mechanical aptitude and practical problem-solving skills
Nice to Have Experience designing pressure housings, sealed enclosures, or waterproof electromechanical assemblies
Experience working with marine-grade materials and corrosion-resistant design practices
Experience working directly with machine shops and outside vendors
Experience in a startup or fast-paced R&D; environment with evolving requirements
Who We're Looking For Someone who takes real ownership of a subassembly from concept to production, thrives on hands-on prototyping, testing, and troubleshooting builds, and works well across electrical engineering, manufacturing, and suppliers to get a reliable, manufacturable design out the door.
