Design and integrate complex mechanical systems for robotics, instrumentation, tools, and equipment. Responsibilities include CAD modeling, analytical studies, prototyping, testing, GD&T drawings, BOM management, manufacturing-method selection, cross-functional collaboration, client communication, and technical issue resolution. The role requires onsite work at a client facility in North Reading, Massachusetts, and supports product development consulting projects.
As a Senior Mechanical Design Engineer, you will work with teams designing subsystems for a range of products, tools, and equipment, including robotics, mechanisms, and biotech instrumentation. Specific responsibilities vary by project, but you must have command of mechanical engineering fundamentals and know how to apply them to simple, reliable design.
This role is ideal for someone with a strong technical background, technical leadership experience, and a history in product development consulting. If you thrive in a fast-paced environment but enjoy a casual, flexible work atmosphere, Simplexity may be the place for you.
Job location: Boston area. Note that this role initially requires onsite presence at a Simplexity client site, specifically in North Reading.
SimplexitySimplifying the Complex. Simplexity is a product development engineering firm hired by leading technology companies to design their next-generation products. In an industry of overly complex design and production, we strive for simplicity, reducing product cost and improving reliability for our clients through our Product Development Process.
Why join Simplexity Product Development?
Our teams are close-knit and collaborative, made up of people who want to build something great and delight our customers. That doesn’t mean grinding 60 hours a week. We believe quality, creative work can usually be done in 40–45 hours per week, and that each employee should own their work-life balance.
We offer meaningful engineering, technical growth, and the chance to be on the “front line” of product development. If you thrive on variety and want to work with talented engineers on cutting-edge products, this could be the place for you.
No recruiters please.
Simplexity is an equal-opportunity employer. We celebrate diversity and are committed to an inclusive environment for all employees. Diverse candidates are encouraged to apply.
