Senior Mechanical Test Engineer

Fulfil is a well-funded, rapidly growing, and inclusive company that has developed a custom automation robotics system to pick and pack online orders of groceries and other consumables, bringing delight and a value proposition to consumers that doesn’t exist today. Additionally, its unique design and technology is purpose-built to solve today’s environmental problems in the world’s food supply chain. Founded by a team with previous startup success and backed by top-tier VCs, we are committed to reducing waste, improving environmental impact, and reducing emissions with truly new technology. Our first commercial product launch with the technology was in summer 2022. 

We can’t do it alone -- we’re seeking curious, capable, passionate team members motivated by the opportunity to create lasting impact on the world through their work. This role offers ample growth opportunities while working side-by-side with an impassioned, multi-disciplinary team spanning mechanical design, software, computer vision, systems integration, and ops to design and operationalize world-changing technology.

Fulfil is committed to creating an inclusive culture, and we celebrate diversity of all kinds. If this sounds like the kind of environment that you find intriguing, then please apply even if you don’t feel you meet all the requirements listed below. We'd love to hear from you.

Your Responsibilities

The Senior Mechanical Reliability Engineer will be responsible for developing and performing test methodologies to determine the robustness and long term reliability (LTR) of Fulfil’s robotic systems. As a core part of the R&D team, you will assume a great deal of responsibility ensuring tests are well designed and well executed in order to uncover potential end of life (EOL) issues. You will need to design test fixturing and build test fixtures. This role will require you perform root cause and failure analysis on issues discovered during testing. The ideal candidate must have a keen understanding of fatigue and wear related failure modes but also be knowledgeable in multiple fields including robotics, hardware, electronics and automation in order to handle multiple failure modes that could arise during testing. Communicating clearly with other teams is key to this role to ensure effective solutions are implemented, whether they be design, maintenance or process based. This role offers ample growth opportunities while working side-by-side with a motivated team to bring our innovative and exciting new technology to reality. 

In this role you will:

• Engineer the transition of Fulfil’s system from prototype to production machines by improving their LTR and Robustness over entire expected life time


• Design test fixtures based on current and future Fulfil designs using SolidWorks


• Own creation of test plans for inducing EOL failure on various robotic assemblies and components


• Build models to determine how many units need to be tested and for how long to support specific reliability objectives


• Carry out testing for LTR, ensuring proper execution of methodology including HALT testing


•  


• Perform root cause and failure analysis during the testing cycles 


• Analyze and interpret data from LTR test, presents this data and conclusion to various stakeholders to determine best path forward


• Leverage wide breadth of engineering knowledge to generate proper solutions to an equally diverse set of problems


• Lead projects requiring cross-team coordination, project management, resource management, decision making, and effective communication on tight timelines in order to run effective tests


• Develop and implement new equipment or functionality to improve the Fulfil technical ecosystem


• Identify and implement mechanical design improvements and product changes to solve issues. Verify fix effectiveness with a data driven approach


• Lead 3D CAD and BOM generation, perform detailed design work on large complex systems


• Create detailed component and assembly drawings using GD&T


• Work with NPI and Operations teams to drive hardware deployment in new facilities


• Maintain a functional reliability lab, ensuring tests are running and tools and equipment are organized

What We’re Looking For

• Bachelor’s degree in mechanical engineering or similar


• ASQ CRE certification


• 5+ Years Experience with running LTR or EOL testing on mechatronic systems


• Experience with creating and building test fixtures in 3D CAD


• Experience creating and executing on test plans or research studies


• Experience working with mechatronics hardware – motors & drives, sensors, actuators, etc.


• Experience with life data analysis, including zero-failure and k-failure test plans, censored data, confidence bounds (e.g., chi-square methods), and MTBF or B-life estimation.


• Familiarity with Weibull++, ReliaSoft, JMP, or equivalent tools


• Hands on aptitude – able to dive in and troubleshoot a variety of system issues across multiple engineering disciplines, but with a focus on those related to wear and degradation of components


• Experience designing mechanical components


• Desire to work in an incredibly fast paced startup environment


• Cares about the world and wants to have an impact on it

What we’d love to see

• Familiarity with HALT, HASS and HASA and applying concepts to primarily mechanical systems


• Experience in SolidWorks, PDM, and Arena Solutions PDM


• Experience with end of life cycle testing with typical wear components in robot systems, Belts, gears, motors, bearings, springs, etc 


• Experience designing and manufacturing parts/assemblies/mechanisms


• Experience with mechatronics systems (robotics and control systems)


• Experience with designing mechanical systems


• Experience in food tech


• Experience managing engineering projects


• Not afraid of robots

What You Get

• A chance to be an early team member and leader of a rapidly growing startup and have an impact on company and technology direction


• The ability to solve challenging problems with a skilled, dedicated and friendly multi-disciplinary team


• A balanced, highly collaborative work environment 


• A Hybrid work structure


• Competitive medical, dental, and vision coverage, with 401K, life and disability coverage


• A PTO policy where we encourage and expect all employees to take time to enjoy life outside of work 


• The salary range for this position is $135,000- $160,000 plus stock and benefits. Pay within the range is based on candidate experience, job-specific skills, education, and work location.

At Fulfil we value diversity and always treat all employees and job applicants based on merit, qualifications, competence, and talent. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
