Senior Mechanical Engineer

Locus Robotics is seeking a Senior Mechanical Engineer to support the development of our autonomous mobile robots and related accessories.

This role sits within the Hardware R&D group and focuses on design, analysis, and cross-functional collaboration to bring scalable, cost-effective hardware solutions to production.

Onsite position is located at our Wilmington, MA headquarters, requiring five (5) days per week onsite. Only local candidates will be considered.

Responsibilities

• Take the inputs from both internal and external customers and generate sub-system requirements for new and existing robots.
• Design, model, and detail draft elements of autonomous mobile robots and their supporting accessories using SolidWorks.
• Utilize a set of requirements to design elegant solutions both quickly and carefully, independently preempting issues of manufacturability and future maintenance.
• Evaluate designs for strength, stiffness and long life, including fatigue analysis of static components and life estimation for bearings or gears.
• Design components and systems that reduce assembly effort; work with the operations team to verify these approaches and incorporate their feedback.
• Design individual components that can be manufactured in high volume at low cost while meeting functional requirements.
• Proactively engage with suppliers to determine competitive manufacturing strategies for new and existing designs.
• Build and test prototype and pre-production robots and subassemblies.
• Work with manufacturing and procurement teams inside Locus Robotics to meet development and production timelines.
• Develop test plans for verification and validation of designs.
• Accurately document work and present this work to peers, customers, and company leadership.

Qualifications

• BSME or MSME with at least 7+ years of relevant industry experience
• Academic or hands-on experience in robotics, mechanical, or electromechanical design
• Familiarity with design for manufacturability (machined parts, sheet metal, castings, thermoplastics)
• Ability to design and execute experiments to validate robot performance
• Hands-on prototyping experience (machining, 3D printing, rapid iteration methods)
• Strong verbal and written communication skills
• Working knowledge of GD&T and engineering drawing standards
• Experience generating RFQs and collaborating with suppliers
• Exposure to risk analysis methods (e.g., What-if analysis, FMEA)
• Collaborative, hands-on team player mindset
• Comfortable with occasional customer interaction

The expected base salary range for this role is $130,000 to $170,000 annually, based on external market data, plus bonus and equity.  Actual offers will depend on factors such as the candidate’s experience, education, training, key or critical skills, geographic location, and current market and business conditions.
