Hypervolt is at the forefront of the energy transition and is dedicated to providing innovative and reliable EV charging and grid management solutions. We launched in 2021 with the bold ambition to accelerate EV adoption by relentlessly focusing on the customer experience, great software, and beautifully designed hardware.
- Design, develop, and optimise embedded firmware for V2G systems
- Integrate and manage peripherals essential for V2G operation, including ISO 15118/IEC 61851, SPI, I2C, RS-485, and Ethernet (IPv6 stack support).
- Develop firmware for high-volume V2G products with a focus on grid compliance, scalability, maintainability, and over-the-air upgradability.
- Collaborate closely with hardware, power electronics, and compliance teams to ensure firmware is aligned with electrical safety, EMC, and grid certification requirements (e.g. G98/G99, UL).
- Conduct in-depth debugging using Wireshark, logic/protocol analysers, and power analysers in a real-world EV and grid-connected context.
- Support factory test firmware and diagnostics to ensure reliable mass production of V2G-enabled hardware.
- Document firmware design, architecture, communication protocols, and regulatory considerations for internal and external stakeholders.
Qualifications:
- Solid experience in firmware development for embedded systems, ideally in energy or power electronics applications.
- Deep understanding of the Linux TCP/IP stack
- Proficient in embedded C/C++, with strong skills in optimising for low-latency and deterministic behaviour.
- (nice to have) Strong understanding of MCU peripherals and protocols used in EV and smart grid integration (CAN, UART, SPI, Ethernet, RS-485).
- Demonstrated ability to work across cross-functional teams, especially with power engineers, test engineers, and compliance teams.
- Experience developing production-ready firmware for mass-manufactured products, with attention to robustness, diagnostics, and lifecycle management.
- Competent with debugging tools: oscilloscopes, logic analysers, protocol analysers (CAN, Modbus, etc.).
- Familiarity with version control (Git) and CI/CD workflows for embedded projects
- Experience with Vehicle-to-Grid communication protocols such as ISO 15118, OCPP, or IEC 61850.
- Exposure to embedded Linux environments (Yocto) and integration of V2G edge devices with cloud backends.
- Scripting skills in Python for test automation, validation, or production line support.
Background in energy metering (active/reactive power), grid synchronisation (PLL), and safety-critical firmware development (ASIL, SIL, etc.).
