Senior Cooling Systems Engineer, Power Battery Systems

Location: Sheffield, GB

To design, engineer & deliver, from concept to series-development, programme specific ESS cooling systems, ensuring they fulfil all the programme requirements (cost, timing, performance / function / attributes).


Key Responsibilities:


  • Detailed ESS cooling system knowledge and experience – programme specific ESS attribute delivery/support, managing design releases, specifications, DVPs, DFMEAs, BCR (QCRs)
  • ESS cooling system ownership and delivery
  • ESS cooling system assembly planning and allocation
  • ESS cooling system analysis (where required)
  • ESS cooling system supplier management
  • Design-focused vehicle level meetings for ESS cooling system integration


Principal Accountabilities:


  • Guarantee ESS cooling system delivery to vehicle projects – to specification, on time, on budget.
  • Understand and support the package constraints for the ESS.  Work with ESS suppliers, Concept teams & DMU to ensure programme-specific ESS meets technical and package targets. Deliver detailed designs on time to defined quality, cost and weight targets, within DFM requirements
  • Support links with external organisations such as universities, research organisations, etc. on collaborative research projects that will help McLaren deliver innovation in ESS cooling system technologies where appropriate. This would include research projects with universities or other like-minded organisations collaborating with the Engineering Manager/Principal Engineer of ESS and Head of Electric Drive Technology (EDT) to exploit such opportunities.
  • Work within, and influence, the Vehicle Programme & Engineering Management teams to guarantee that the EDT department responsibilities collectively deliver the whole vehicle specification targets.
  • Work with the other systems engineers and designers and the ESS supplier to achieve efficient, innovative and lightweight designs.
  • Ensure design solutions deliver systems that meet attribute targets in thermal, NVH, durability, & performance attributes (power, emissions, and response).
  • Ensure the ESS cooling system interfaces seamlessly to the vehicle cooling systems.
  • Work with Supply Chain Management to ensure delivery of the ESS on schedule for all phases of prototype, pilot, pre-production and production build.
  • Prepare and present material to support external and internal project status reviews
  • Provide support on ESS technical risk management to ensure project delivery, optimised vehicle performance and delivery of hybrid system attributes.
  • Guarantee ESS cooling system ownership and delivery to the specific vehicle programme requirements including:
  • Component Specification which specifies integration requirements for the ESS cooling system with other ESS and Hybrid Electrical System (HES) components.
  • Electric Drive System FMEA, ESS cooling system FMEA; System and ESS cooling system DVP; Support Vehicle / Electric Drive System test specifications
  • Support management of ESS development budgets & expenditure
  • ESS cooling system planning, timing & delivery including design, release & change-requests in line with ETRS requirements, development and validation plans
  • ESS cooling system BOM management & tracking
  • Robust concerns resolution
  • Vehicle build & development support
  • Delivery of ESS cooling system `for all projects in line with McLaren Development Process (MDP) and that Project Management KPIs are on track           


Knowledge, skills and experience


  • Technical knowledge & experience of ESS cooling system design, test & production delivery
  • Ability to define requirements and conduct analysis for cooling systems and components, including pumps, heat exchangers, pipes & hoses, expansion/header tanks, cooling fluids.
  • Knowledge of heat generation and heat flow paths in electrochemical cells, electrical conductors and other current-carrying ESS components.
  • Ability to support ESS mechanical design, GD&T, packaging & release
  • Understanding of Li-Ion technologies, BMS, Functional Safety and High Voltage Switchgear
  • Support of cell, module and pack testing to facilitate data gathering and analysis
  • Support of testing with HiL (Hardware in the Loop) and Rig systems to prove integration quality
  • Experience of executing ESS cooling system DVPs, FMEA and DFM plans
  • PC literate and at ease with MS Office products.                                                                                        
  • Experienced in OEM or Tier-one component delivery
