Senior Hardware Engineer (EV Charging

Allye Energy is seeking aHardware

Engineer with an electrical and electronics background to lead the development and integration of DC fast charginginto our range of battery energy storage systems. This roleisresponsible forthe system architecture development, software integration, and technical implementation that enables our BESS to both recharge from public DC fast chargers and integrate EV charging hardware into our energy storage solutions.

It requiresintelligent system integration and software architecture that bridges the gap between DC fast charging infrastructure and battery energy storage systems.

• Design and develop core system architecture for integrating third-party DC fast chargers (from OEMs like Alpitronic, ABB, Kempower, etc.) with Allye's BESS
• Create interface specifications and communication protocols between EV charging hardware and our battery management systems
• Ensure integration supports bidirectional energy flow between BESS and charging infrastructure

Leadsoftware integrationactivities,workinghands‑on and with the existing embeddedcontrolsand application softwareteams, to deliver:

• Updates to our BESS control system and to implement OCPP (Open Charge Point Protocol)
• Develop and maintain communication interfaces for charging session management, billing integration, and real‑time monitoring
• Create robust API frameworks for seamless integration with charge point management systems (CPMS)
• Implement security protocols and encryption for safe data exchange between systems
• Work with Web Socket, MQTT, REST APIs, and other communication protocols

• Enable Allye's BESS to recharge from public DC fast charging networks
• Develop adapter strategies and interface solutions for different charging connector types
• Implement smart charging algorithms that optimise energy flow based on grid conditions, battery state, and charging rates
• Create interoperability solutions ensuring our systems work with existing and emerging charging standards

• Design electrical interfaces and control systems for integration with existing EV charging hardware
• Collaborate with mechanical engineers on physical integration challenges and thermal management
• Develop safety systems and emergency protocols for high‑voltage DC charging integration
• Create test procedures and validation protocols for integrated charging systems

• Ensure compliance with relevant industry standards: SAE J1772, IEC 61851, UL2202, ISO 15118
• Support certification processes for integrated systems (CE marking, UL listing, etc.)
• Stay current with evolving EV charging standards and emerging technologies like Plug & Charge and Vehicle‑to‑Grid (V2G)
• Maintain knowledge of grid codes and utility interconnection requirements
• Work closely with software, mechanical, and systems engineering teams
• Create comprehensive technical documentation including system specifications, integration guides, and troubleshooting procedures
• Support field deployment and provide technical guidance for installation teams
• Collaborate with external partners, OEMs, and certification bodies

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or related field
• 3-5 years of experience in EV charging infrastructure, power electronics, or automotive electrical systems
• Hands‑on experience with DC fast charging systems (50kW-350kW+ power levels)
• Proven track record in system integration projects involving multiple hardware and software components

• EV Charging Expertise:Deep understanding of DC fast charging standards, protocols, and hardware (CCS, NACS, CHAdeMO)
• OCPP Protocol:Hands‑on experience implementing OCPP 1.6 and familiarity with OCPP 2.0.1
• Software Development:Proficiency in C/C++, Python, or similar languages; experience with embedded systems and real‑time programming
• Communication Protocols:Experience with Web Socket, MQTT, CAN bus, Modbus, and TCP/IP networking
• Power Electronics:Understanding of high‑voltage DC systems, power conversion, and energy management
• System Integration:Ex…
