Company DescriptionAMPLY has been awarded the 2020 Global CleanTech 100 company and honored for Innovation in Electric Vehicle Fleet Charging and Management. AMPLY is an energy technology company going after an emerging $100B market opportunity. We are looking for individuals with a passion for technology and exceptional skills in embedded firmware systems design. As the principal engineer you will design, test, validate, document, and take ownership of AMPLY’s technical charging depot including local / micro-controllers needed onsite. This is a full-time position based at our HQ office in Mountain View, CA.Job DescriptionAs our Principal Engineer of Platform and Embedded Systems, you will test and validate 3rd party EV charging station hardware, ensure the interoperability and service SLA with both AMPLY’s cloud platform and the vehicle to charger communication, ensure communication between the charging station and the cloud complies with specifications (CCS, OCPP), troubleshoot the latter if needed, and define AMPLY EV charger HW specifications. You will also be responsible for AMPLY’s technical charging depot design including local / micro-controllers needed on site. You will test, document and manage the various combinations of suppliers tied together via level 2/3 charging protocols (CCS, OCPP, and others) while working closely with your development and operations colleagues, to ensure the industry’s highest availability and reliability. Participate in and drive all aspects of the third party EVSE and vehicle OEM validation process with emphasis on end-to-end system validation, and > 99.5% availability, test and validate EVSE / embedded software modular system design including redundancy, reliability, failover, and automated recoveryTest and deploy the hardware / embedded SW integration part of the overall technical system architecture, with a view to achieve 99.5% end to end service availabilityInteroperability testing between AMPLY cloud platform, third party hardware and vehicle, based on (evolving) industry standards like OCPP, CCS, and othersValidate specs by creating HW / system test fixtures, creating and managing (in production, throughout lifecycle) firmware configurations dedicated to cloud platform integrationsYou will bootstrap the setup of various EV charging station installations (lab first, later in field)Regression testing of new firmware on existing cloud platform integrationsDesign and develop depot technical architecture including AMPLY’s site / local controller embedded systemDefine AMPLY EV standard charging station technical specification and integrations with third party EVSE platformsQualificationsBachelors or Masters in Electrical Engineering, Power Electronics or Computer Engineering5 years of Embedded Software development experience3 years HW and Firmware Specification and validation of low/medium voltage EV charging stations (EVSE)5 years of Embedded Software testing and validation experience in the EV industry, automotive or electrical industryGood knowledge of evolving level 2/3 charging protocols, CCS / OCPP / CharIn, and preferably hands-on experience with vehicle to charger to cloud integration testingKnowledge on M2M communication standards and platformsStrong troubleshooting/analytical skillsProven skills in providing technical documentationGood programming skills, in Embedded C, C , Linux and Python, experience with IoT frameworksProven history of successful problem solving with strong sense of ownership and urgencyAdditional InformationAbout AmplyAMPLY is redefining the EV charging market for private and public fleets, including autonomous driving fleets, transit bus agencies, municipal and private fleets. We are building the next level of charging as a service, taking complete ownership and control of the charging infrastructure, the scheduling of the vehicles, the cloud platform and the utility meter – in order to provide the highest availability and resilience in the market. In this way, we will accelerate the adoption of electric powered fleets by optimizing the delivery of power and making refueling seamless and efficient.In a high-powered application like vehicle fast charging, the difference between controlled, optimally balanced vs unrestrained EV charging could be 3x in cost from your local utility. Even more importantly, EV fleets, in particular when part of critical and close to real time business processes (for example in autonomous fleets) need to be scheduled for charging in specific time intervals. By taking control of the utility meter, optimizing EV charge rate and vehicle process flow, AMPLY provides the lowest cost of electric fueling possible in a given depot location or in-route stops.Our approach is to offer charging as a service, which is unique in the industry. We offer our customers a per mile driven usage rate. AMPLY provides the bulk of the upfront capital expenditures associated with the charging platform.NOTE: All your information will be kept confidential according to EEO guidelines.
