Team Leader Embedded Hardware
Malmesbury, United Kingdom
Embedded Hardware Electronics Team Leader in the Motors, Power and Electronic Systems Research Team.
Market OverviewHome to our global Research, Design and Development centre and all of our Commercial functions, Dyson HQ is tucked away in countryside famous for the railway tunnels and bridges of Isambard Brunel, who revolutionised modern engineering. Our secluded location helps us to protect our ideas and stay independent-minded. Yet nearby are the fashionable cities of Bristol and Bath (where a young James Dyson invented cyclone technology). The building is the heartbeat of Dyson. Over 1,500 people, including James himself, spend their days strategizing, inventing technology and telling the Dyson story to the world. From 2016, our HQ will begin doubling its footprint with an ambitious new expansion.
Function OverviewSometimes, making a technological leap forward means going back to the beginning. Since 1999, we’ve spent £150m building a motor from scratch – small, light and efficient, yet extremely powerful. Our motors are what enable our technology to be different – it’s why they’re protected by 20 to 30 patents. But the next generation demands new directions. Energy storage, robotics, nanotechnology and space-age materials. So our multi-disciplinary team, led by some of the world’s best power electronics engineers, knows that only the most pioneering thinking will do. That’s the Dyson way.
Lead and take technical responsibility for a growing hardware electronics team covering multiple diverse systems
Work with fellow Motor and Power System teams to deliver an optimum electrical system architecture for the new product, for example defining which aspects will be implemented in hardware or software.
Display strong creativity together with the technical expertise and the sound judgement required to understand the interdependencies between sub-systems and develop requirements accordingly.
Ensure the hardware team develops the concept, proves key technologies and demonstrates designs are robust, cost effective and fit for purpose for the manufacturing environment, through detailed analysis, simulation, design review down to component level and laboratory testing
Deliver hardware electronics solutions that meet target specifications such as cost, size, weight, functional safety and efficiency within the planned timeline; are reliable and fit for purpose; satisfy life requirements and achieve product guarantee periods; whilst comply with all relevant International Standards.
Ability to assess and handle component supplier relationships particularly with regard to technical negotiations, maintaining confidence in BOM and assembly costs throughout a project.
Work closely with the Systems Manager, Project Manager(s) and Research Managers of other engineering disciplines to drive resolution of technical and other issues in order to ensure that the product performance, reliability and cost expectations are met, all within the planned timeline of the project
Delivery of the hardware electronics validation test plan, including associated logistics and test equipment
Working with production engineering, provide technical support throughout the latter stages of development and into production
Assist in the recruitment and personal development of the hardware team and undertake annual appraisals of the team members
Education and experience;
Minimum BEng/MEng degree (2:1 degree or better) in Electronic Engineering or other relevant discipline.
Clearly demonstrate experience defining and developing complex interdependent electrical systems.
Minimum technical knowledge:
Experience in electrical system architecture definition (i.e. hardware/software split), incorporating redundancy/diversity to achieve the desired level of functional safety
Excellent knowledge of all aspects of low power SM PSU hardware design, fed from both low and high voltage DC.
Proven experience in the design of closed loop controllers for SM PSU
Sensor signal interfacing, amplification and filtering
Detailed understanding of interfacing to micro controller based systems
Communication interfacing (e.g. I2C, SPI, UART,)
Device selection - Interpretation of datasheets and knowledge of design methods to confidently select the most appropriate solution
PCB layout for best compromise between functional performance, cooling, cost, insulation coordination,EMC, manufacture and overall packaged volume.
Thermal design – e.g. component placement, specification of potting, forced air cooling
Design and specification of passive components, particularly inductors and transformers
Design tolerance analysis
Definition and implementation of verification test plans
Definition and design of hardware test systems
