Original job description

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.

Architect, design, and integrate complex mechanical systems.
Communicate design concepts efficiently using block diagrams, rough CAD, schematics, and sketches.
Design solutions using custom (injection-molded, machined, 3D-printed, sheet metal), semi-custom, and off-the-shelf parts.
Perform analytical studies applying engineering principles such as force and energy balances, structural calculations, mechanical vibration, tolerance analysis, and power transmission.
Manage large 3D CAD assemblies.
Generate and maintain an organized bill of materials.
Create 2D drawings to ASME Y14.5 GD&T standards.
Quickly prototype design concepts, test against specifications, and iterate.
Collaborate with engineers across disciplines.
Select manufacturing methods for prototyping and production, and design components accordingly.
Prioritize technical issues on your designs and drive them to resolution.
Communicate regularly with clients and project management on project status, issues, design decisions, and risks.
Coordinate with external partners such as industrial design and contract manufacturing firms.
Work on-site at client facilities in the local area, such as North Reading, MA
Conduct or inform simulations (structural FEA, thermal FEA, CFD, etc.) as needed.

QUALIFICATIONS

BS or MS in Mechanical Engineering from an accredited four-year university
10+ years of relevant professional engineering experience
Proficiency in SolidWorks (highly preferred) or an equivalent CAD package
Thorough understanding of 2D drawings, preferably with strong GD&T (ASME Y14.5) skills, and how they apply to design and manufacturing
Knowledge of manufacturing processes and design considerations: injection molding, sheet metal, machining, rapid prototyping, etc.
Knowledge of assembly and alignment methods: screw joints, snap fits, dowel pins, heat-staking, etc.
Ability to root-cause system-level defects
Experience designing and integrating complex systems with cross-functional teams (electrical, firmware, software, and systems engineers)
Strong organizational and analytical skills, attention to detail, and the ability to plan and prioritize effectively
Highly motivated, with a demonstrated ability to work independently with minimal supervision
Clear communication and detailed report writing skills
Positive attitude and focus on client success
Ethical and honest in every part of the job

PLUSES TO HAVE

Experience with mechatronics and electro-mechanical systems, including stepper and DC motors, solenoids, gear and belt drives, linear actuators, bearings, sensors, and electronics
Product development consulting experience with clients
Experience using a CAD PDM system to manage CAD files
Robotics, instrumentation, and test equipment design experience
Pneumatic and/or hydraulic system design experience
Medical device experience, including work within a medical quality system
Finite Element Analysis, Computational Fluid Dynamics, or other simulation package experience

COMPENSATION AND BENEFITS

Base salary range: $135K–$165K, depending on experience and skill set
Excellent healthcare plan (medical, dental, and vision), fully paid by the company for employees and partially paid for dependents
401(k) plan with company match
Short- and long-term disability, AD&D, and life insurance
Paid maternity/new parent leave
11 paid holidays
3 weeks of paid time off (PTO) per year, increasing after 2, 5, and 9 years of service

Job location: Boston area. Note that this role initially requires onsite presence at a Simplexity client site, specifically in North Reading. Simplexity Simplifying 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.
