The Role
Designs and integrates complex mechanical systems for robotics, instrumentation, medical devices, and other products. Responsibilities include CAD assemblies, drawings and GD&T, engineering calculations, prototyping, testing, manufacturing method selection, bills of materials, issue resolution, and system integration. Leads and mentors engineers, collaborates cross-functionally and with clients, coordinates external partners, and may support FEA, thermal analysis, or CFD simulations.
Summary Generated by Built In

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?
Simplexity works across a breadth of projects — from robotics and IoT to medical devices, consumer wearables, automation and more. You’ll roll up your sleeves and help solve difficult problems for demanding clients who expect excellence.
Our teams are tight, collaborative, and made up of folks who genuinely want to build something cool and delight our customers.  Yet that doesn’t mean grinding for 60-hours per week, week-over-week.  We believe that quality, creative work can usually be done in 40-45 hours per week and that each employee should own their work-life balance.
What we offer is 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, then this could be the place for you.
POSTION DESCRIPTION
As a Senior Mechanical Design Engineer, you would be working with and leading teams designing subsystems of various products, tools, and equipment. We are seeking candidates to develop complex products that include robotics, mechanisms, biotech instrumentation as well as other components. Specific technical responsibilities vary by project; however, it is imperative that you have command of all mechanical engineering fundamentals and understand how they are applied to simple, reliable design. 
This position is ideal for someone who has a strong technical background, technical leadership experience, and has worked in product development consulting. If you thrive in a fast-paced environment, yet enjoy a casual and flexible work atmosphere, then Simplexity may be the place for you.  

  • Architect, design, and integrate intricate mechanical systems.
  • Efficiently represent concepts for your designs using block diagrams, rough CAD/schematics, sketches, etc.
  • Solve problems and design solutions that incorporate custom (injection-molded, machined, 3D-printed, and sheet metal), semi-custom, and off-the-shelf parts.
  • Perform paper-studies using various mechanical engineering academic principles, such as force and energy balances, structural calculations, mechanical vibration, tolerance analysis, mechanical power transmission, etc.
  • Manage large 3D CAD assemblies of many components.
  • Generate and maintain an organized bill of materials.
  • Create 2D drawings using ASME Y14.5 GD&T standards.
  • Quickly and effectively prototype design concepts, test specifications, and iterate on the design.
  • Lead and mentor more junior engineers.
  • Work collaboratively with other engineers of various disciplines.
  • Identify appropriate manufacturing methods for prototyping and production.  Design components appropriately for those manufacturing methods.
  • Manage, organize, and prioritize technical issues on your designs and drive toward resolution.
  • Work closely and communicate regularly with clients and project management to keep stakeholders apprised of project status, issues, design decisions, and risks.
  • Coordinate with external partners in areas like industrial design and contract manufacturing.
  • Support working on-site in the Seattle Metro area.
  • As-needed - conduct or inform simulations such as structural FEA, thermal FEA, CFD, etc.

QUALIFICATIONS

  • 8+ years of relevant professional engineering experience.  
  • Proficient knowledge of SolidWorks (highly preferred) or equivalent CAD package. 
  • Thorough understanding of 2D drawings, with a preference for strength in GD&T (ASME Y14.5) and how it is applied to design and manufacturing. 
  • Demonstrable knowledge of manufacturing processes and mechanical design considerations – injection molding, sheet metal, machining, rapid prototyping, etc. 
  • Demonstrable knowledge of assembly and alignment methods - screw joints, snap fits, dowel pins, heat-staking, etc.
  • Ability to identify and root-cause system-level defects. 
  • Experience in design and integration of complex systems working closely with cross-functional disciplines (electrical, firmware, software, and systems engineers). 
  • Excellent organization and analytical skills combined with attention to detail. Ability to prioritize and plan effectively. 
  • Highly motivated with demonstrated ability to work independently with minimal supervision. 
  • Ability to communicate clearly and write detailed reports. 
  • Have a positive attitude and focus on client success. 
  • Ethical and honest in every part of the job.
