Senior Mechanical Design Engineer - Power Systems

Lightship • South San Francisco, CA

1d • $125,000 - $150,000 • Hybrid

About The Position

As a Senior Mechanical Design Engineer you will serve as a hands on technical lead for multiple power systems sub-systems, primarily our all-electric RV’s Solar System. You will be responsible for continuing developing, prototyping, and testing of the solar arrays, related junction boxes, harnessing, charge controllers and circuit protection. With a small team, you'll also help dive into development on other Power Systems components, including power distribution modules, mounting brackets, electronics enclosures, and selecting off the shelf electronics components

Requirements

• 5+ years design engineering experience
• Comfortable working in a dynamic environment with shifting priorities and needs
• Able to adapt quickly to change and approach challenges with flexibility and creativity
• Solutions-oriented, with a focus on progress and impact over perfection
• Willingness to operate effectively at both strategic and hands-on levels (contributing as an individual contributor and leading as a manager)
• Expertise with a majority of the following:
• CAD/PLM/PDM systems
• Creating detailed 3D CAD and drawings for electrical hardware components (cast/injection molded housings, busbars, wire harnesses, insulators, switches etc).
• Selecting appropriate materials for electrical hardware, including plastics, metals, polymers and ceramics
• Creating design validation plans for electrical hardware
• High voltage power distribution systems
• DFM/DFA analysis
• Bolted joint design and analysis
• Rapid iteration cycles
• Supporting programs in all stages of the product life cycle, from early concepting to supporting production and field service

Nice To Haves

• Experience with solar arrays
• Experience designing wire harnesses (high voltage and low voltage)
• Experience with CATIA (3DX)
• Experience with performing thermal analyses (mixed convective/conductive/radiation HT)
• Experience with structural analysis (basic stress/strain and modal analysis)
• Experience with designing for automotive environments
• Experience performing DFMEAs on electric vehicle power systems/propulsion systems
• Experience with systems engineering and software based vehicle architectures

Responsibilities

• Engineering development and requirements generation:
• Work with the Product and Design teams to develop high level product requirements, and create lower level engineering requirements for your sub-systems by working with the various engineering teams (systems, controls/software, vehicle engineering)
• Review regulatory requirements and ensure all components are designed to meet them
• Work with the supply chain and finance teams to ensure all subsystems are meeting cost targets
• Perform Design Failure Modes & Effects Analysis (DFMEA) to highlight reliability and safety issues. Use the outputs of this process to create design fixes and drive test plans
• Create timelines and schedules for all subsystem development and work with the program team to ensure these are meeting high level milestones and development goals
• Create detailed CAD and drawings of all custom components. Work with the CAD/PLM team to ensure all packaging issues are resolved and all parts are released
• Select off the shelf components that meet all functional, durability, cost and quality needs
• Create tolerance stack analyses and apply appropriate GD&T controls to 3D geometries
• Hold design reviews with the cross functional team to ensure all considerations are taken into account
• Host core team meetings to push forward work and collaborate with the cross-functional teams
• Work with supply chain to select appropriate suppliers, and work with suppliers to ensure components can be manufactured by performing detailed design for manufacturing (DFM) analysis
• Testing and analysis:
• Create design validation plans (DVPs) by working with the test engineering team
• Perform all necessary analysis (thermal, structural, etc) to reduce risk of design failures and ensure we meet performance targets
• Build functional prototypes of subsystems to ensure early de-risking before full vehicle builds
• Perform engineering validation (EV) testing of subsystems to characterize performance and safety
• Work with the test engineering team to troubleshoot issues from highly accelerated life testing (HALT) and vehicle level test failures
• Build, production, and aftersales support
• Create work instructions by working with the production operations teams and performing design for assembly (DFA) analysis
• Perform first article inspections of components from suppliers and work with in house quality engineering to triage quality issues
• Support prototype and production builds in Broomfield, CO factory (10-15% of time, depending on the phase of development)
• Support field service engineering of customer vehicles and marketing vehicles

Benefits

• Healthcare, Dental, Vision
• 401k
• Flexible Paid Time Off - that we actually want you to use!
• 8 Company Holidays + the company observes a period of scheduled downtime during the end of the year for a week, allowing all employees to enjoy a break
• 12 weeks paid parental leave
• $2,000 per year towards an RV trip of your own &/or professional development opportunities - we call this a LightTrip
• Lightship offers all of its full time employees and their dependents full benefits including health, dental and vision insurance and covers 100% of the insurance premium. We are on a mission to create a more healthful all-electric experience for a pastime that millions of families enjoy and believe strongly that our team should not have to worry about quality healthcare for themselves or their loved ones along the way.
