Chief Engineer -- responsible for all system engineering activities on lead high voltage program (Class 2b delivery vehicle), including product architecture and product compliance matrix.

Troy, Michigan, Us

Lead battery design for electric and hybrid vehicles.

Cedar Park, Texas, Us

Transportation start-up commercializing hybrid systems to reduce fuel usage for Class 8 tractor trailers. • Led design for manufacturability (DFM) efforts to bridge gaps in supply chain and cut vendor lead time for critical prototype custom sheet metal hardware in half, keeping company schedule on track.• Rapidly designed and manufactured fixtures for assembly of ~400V battery systems, cutting production cycle time and improving operator safety. Reduced fixture cost 50% while maintaining critically short lead time (1 week).• Developed a comprehensive process for subsystem assembly, test, and installation which clarified roles and responsibilities, communicated to operators and managers the current build status, highlighted roadblocks, and prompted the next action to be completed.• Initiated and steered discussions to inform stakeholders of production issues and risks, using tools such as JIRA and Google Sheets to clearly establish ownership and responsibilities for action items.• Liaison to contract manufacturer for initial production runs, responsible for in-process deviations, build issue documentation, reconciliation of BoMs, and on-the-floor engineering decisions. Delivered over $150k in battery systems per week to meet revenue targets.• Designed and conducted component level verification tests and end-of-line tests to support the production line, reduce cycle times, and lower total COGS.• Created programs to address EHS risks and meet OSHA mandates.

Green technology start-up commercializing a new battery chemistry for grid-scale energy storage.• Scoped and executed full-cycle product development plans to bring successively lower cost versions of the core product to market.• Led engineering teams to implement production changes, resolve supplier quality problems, and develop the next generation of product designs.• Identified process gaps, established best practices, and collaborated cross-functionally to scope and implement improvements to the Product Development Process.• Investigated and resolved product quality issues using Root Cause Analysis tools such as 5 Whys and FMEAs.• Developed custom data collection systems to monitor and log force, displacement, pressure, temperature, and strain procured and created metrology and test equipment, and construction of prototype fixtures.• Determined appropriate test standards for regulatory compliance (SAE, CE, UL, FCC), coordinated outside test labs, and prepared reports, leading to UL-recognition and C2C certification of the battery product.• Managed equipment, tooling, and layout of custom fabrication shop for rapid development of battery designs and fixtures.• Performed installations and field support of products, resolving logistical, software, and hardware issues on site.• Conducted lab- and pilot-scale builds for battery and component testing.Former Roles:2010-2011 Mechanical Engineering Co-op2011-2016 Mechanical Engineer2016-2017 Field Service Engineer (concurrent with other roles)

-Created initial design and led implementation of product components, and managed interfaces and dependencies in all stack-level product lines at each level of the Product Development Process.-Supported design activities with creation of test plans, development of custom data collection systems, procurement and set-up of metrology and test equipment, and construction of prototype fixtures.-Managed outside vendors to complete required regulatory testing (SAE, UL, FCC, etc.) after selecting appropriate standards. -Conducted regular lab- and pilot-scale builds to inform research and development of next generation products and resolve issues with present production-scale designs.-Worked to build and maintain a strong team dynamic through direct and regular contact with teammates using Agile project management tools such as Scrum and sprint planning.
