Senior​/Principal Mechanical Engineer; Stride Shuttle Sorter

• We are seeking an experienced mechanical engineer to support the continued development of the Stride Shuttle Sorter
• Stride is an established product, and this role will focus on improving its reliability, strengthening its technical foundation, and adapting the platform for new applications and markets
• This is a hands-on technical role for someone who enjoys understanding how an entire product works, not just an individual component
• You will investigate complex product issues, identify opportunities for improvement, and help the team make sound technical decisions that balance reliability, performance, cost, manufacturability, serviceability, and schedule
• Success in this position also requires disciplined execution
• Product improvements are only complete when the supporting analysis, drawings, bills of material, test documentation, and engineering changes are accurate and released
• Depending on experience and demonstrated scope, this position may be filled at the Senior or Principal Engineer level
• Develop a strong system-level understanding of the Stride product, including the mechanical system and its interactions with controls, electrical hardware, manufacturing, installation, and service
• Own complex mechanical projects or major areas of the product from problem definition through design, analysis, prototyping, validation, documentation, release, and production support
• Lead investigations into reliability and performance issues using structured root-cause analysis, testing, field data, and sound engineering judgment
• Identify recurring problems and develop robust solutions that address underlying causes rather than individual symptoms
• Evaluate how proposed changes affect the broader product, including reliability, safety, cost, manufacturability, installation, serviceability, and compatibility with existing systems
• Support the adaptation of the Stride platform for new customers, applications, environments, and market segments while managing product complexity
• Provide technical direction for mechanical projects or subsystem-level work involving other engineers and cross-functional partners
• Create and maintain high-quality engineering documentation, including requirements, calculations, drawings, bills of material, test plans, test reports, design reviews, and engineering change orders
• Work closely with manufacturing, sourcing, quality, controls, electrical engineering, installation, service, and product management
• Communicate technical risks, tradeoffs, decisions, and recommendations clearly to both engineering and non-engineering stakeholders
• Review the work of other engineers and help strengthen the team’s technical practices, product knowledge, and documentation quality
• Mentor less-experienced engineers and contribute to a collaborative and accountable engineering culture

• Healthcare
  - Full medical, dental and vision. Life insurance, gym stipends and wellness programs
• Vacation
  - We value hard work and we like to have fun. Take time when you need it
• Recognition
  - Peer shout outs, achievement celebrations and leadership awards let you know you’ve made a difference
• Retirement
  - Stock options and generous 401(k) matching
• Nutrients
  - Lunch is delivered daily, a plethora of snacks, gourmet coffee, Soylent, and top-shelf beverages

Willingness to take ownership of both highly technical work and the detailed documentation required to implement it successfully5+ years of experience

Bachelor's degree in mechanical engineering or a related engineering discipline

Considerable experience designing, developing, and supporting complex mechanical or electromechanical products

Ability to work autonomously while building alignment within a multidisciplinary team Experience taking designs through release and change-control processes, including drawings, bills of material, design reviews, validation, and engineering changes

Demonstrated ability to independently investigate ambiguous technical problems and bring them to a documented, production-ready resolution

Experience improving the reliability of an existing product through root-cause analysis, testing, and design changes

Ability to understand system-level behavior and recognize how a change in one area may affect the rest of the product

Sound engineering judgment and the ability to make practical tradeoffs among technical performance, risk, cost, schedule, and product complexity
