Mechanical Engineer - Maritime

Spear AI is seeking an experienced Mechanical Engineer with maritime experience. You will be part of a cross functional team designing, building, testing, and deploying unmanned maritime sensor systems.

You will be in the lab and out on the water frequently.

• Serve as the second and senior mechanical engineer in the team, mentoring junior engineers and technicians.
• Structural and Functional Design – Design and document mechanical systems applying both analysis and intuition as appropriate. Optimize for various factors and ensure compliance with requirements.
• Design for operational maritime use including submerged systems – Design systems with an operator‑centric viewpoint that will survive and thrive in challenging maritime and submerged environments.
• Produce Mechanical CAD artifacts including drawings, documentation, and revision control.
• Select and determine appropriate manufacturing processes, generate appropriate documentation for technicians or suppliers, and optimize designs for the selected processes. Emphasis on distributed/low‑tech manufacturing and avoidance of precision machining.
• Additive Manufacturing – Design parts for additive manufacturing, understand how to optimize additive manufacturing, and determine appropriate testing regimens for additive parts.
• Prototyping and Troubleshooting – Build, test, and troubleshoot prototypes of designs. Engineers should be heavily involved in building the initial prototypes.
• Handoff to manufacturing – Develop documentation, procedures, and artifacts to transition manufacturing processes to technicians.
• Operational Testing – Plan, support, and participate in operational testing of prototypes including bench testing and field testing up to sea during early stages.
• Incorporate feedback – Elicit and incorporate feedback from assembly and field technicians throughout the design cycle to improve performance, reliability, and cost effectiveness.

• A B.S. in Mechanical Engineering or Naval Architecture and minimum 5+ years of relevant experience (or a minimum of 10 years of highly relevant experience with a minimum of five years of experience working in a design role).
• Prior maritime design experience.
• Familiarity with standard mechanical engineering tools and processes. Solid Works preferred but not required, provided you can cross over to Solid Works quickly.
• Extensive hands‑on experience in prototyping, testing, and refinement of designs in the lab and preferably in a field environment.
• Suitable written and verbal communication skills for working in a high‑performing development team.
• Ability to physically participate in at sea deployment, test, and recovery operations, including carrying and maneuvering on a small boat at sea, communicating verbally, and carrying out fine manipulations.
• Willingness to receive a Secret or Top Secret/SCI security clearance. This will be at no expense to you. Failure to obtain or maintain a clearance will be grounds for termination.

• Prior experience with small boats and at sea operations.
• Prior experience with UxS (Unmanned Systems) – desired.
