• Design and review electrical schematics, defining hardware architectures for new products
• Partner with Mechanical Engineering, Android and embedded software, Product and Supply Chain teams to align platform choices, interfaces and product integration
• Own hardware delivery from prototyping and bring up through validation and mass production readiness, debugging designs and reducing technical risk along the way
• Explore new design approaches and prototype untested concepts to work through tough technical challenges
• Lead technical workstreams and design reviews, coordinate implementation across cross functional teams, and mentor colleagues to share hardware engineering knowledge

You'll be great for this role if…

• Significant experience in electrical engineering, gained in consumer electronics or hardware product development.
• Strong knowledge across several of the following areas: RF (cellular, NFC, Wi-Fi/BT), power design, digital buses and protocols, battery technology or analogue design.
• Track record of bringing multiple hardware products through to mass production.
• Proficiency in a mainstream CAD system such as Altium or Cadence/Allegro.
• Ability to create hardware architectures for modern Android based products and work closely with Android or embedded software teams on platform integration.

Nice to have:

• Bachelor's degree in Electrical Engineering, with a Master's a bonus.
• Basic coding skills for simple firmware validation, with Android device bring up experience a plus.
