Job description

Job Description BOAB Ventures is seeking a Mechanical Engineer with maritime experience to design, build, test, and deploy unmanned maritime sensor systems as part of a cross‑functional team. You will be the senior of two mechanical engineers on the team, mentoring junior engineers and technicians, and you'll spend time both in the lab and out on the water. This role supports the national security industry, delivering hardware, software, and data solutions that span levels of classification and are intended for operational deployment. You'll join a rapidly growing team committed to rapid development of excellent products through continuous fielding. The ideal candidate has strong maritime design experience, extensive hands‑on prototyping and testing skills, and the ability to carry a design from concept through manufacturing handoff and at‑sea testing. Duties & Responsibilities: * Design and document mechanical systems using both analysis and engineering intuition, optimizing designs and ensuring compliance with requirements

• Design operator‑centric systems that survive and thrive in challenging maritime and submerged environments
• Produce mechanical CAD artifacts including drawings, documentation, and revision control
• Select appropriate manufacturing processes, generate documentation for technicians and suppliers, and optimize designs for those processes - high emphasis on distributed and/or low‑tech manufacturing; precision machining is avoided
• Design and optimize parts for additive manufacturing and determine appropriate testing regimens for additive parts
• Build, test, and troubleshoot prototypes of your own designs - engineers are heavily involved in building the first few units of their work
• Develop documentation, procedures, and artifacts to transition manufacturing processes to technicians
• Plan, support, and participate in operational testing of prototypes, including bench testing, field testing, and going to sea during early prototype stages
• Elicit and incorporate feedback from assembly and field technicians throughout the design cycle to improve performance, reliability, and cost effectiveness - all systems are assembled on‑site
• Mentor junior engineers and technicians Required Skills Requirements: * Active clearance or ability to obtain a Secret or Top Secret/SCI security clearance (at no expense to you); failure to obtain or maintain a clearance will be grounds for termination
• US Citizenship required
• BS in Mechanical Engineering or Naval Architecture with 5+ years of relevant experience (or 10+ years of highly relevant experience including 5+ years in a design role)
• Prior maritime design experience
• Familiarity with standard mechanical engineering tools and processes; SolidWorks preferred but not required if you can cross over quickly
• Extensive hands‑on experience prototyping, testing, and refining designs in the lab, and preferably in field environments
• Strong 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 lifting, carrying, and maneuvering on a small boat at sea, communicating verbally, and performing fine manipulations Desired Skills Preferred Qualifications: * Prior experience with small boats and at‑sea operations (strongly desired)
• Prior experience with UxS (unmanned systems) Additional Details What we offer: * Flexible time off
• Full medical coverage
• 401(k) with company match
• Referral bonuses
• Performance bonuses
• Life insurance and disability coverage
• Tuition and training reimbursement
