Senior Electronics Engineer
Description
HoriZn is pioneering a breakthrough battery technology designed for the high-power markets of the future, supporting the global shift to electrification. Our water-based batteries deliver market-leading performance through a novel polymer separator, combined with zinc halide electroactive species and carbon-based porous electrodes.
To accelerate commercialisation, HoriZn operates a fully integrated product development model - from advanced materials through to cells, modules and packs - underpinned by in-house battery management systems.
As a Senior Electronics Engineer you will be playing a key role in developing the Battery pack electrical architectures and Battery Management System (BMS) hardware to maximise the performance of HoriZn’s high-power cells, modules and packs. You will be involved in the design, development and deployment of battery packs as well as being hands on and supporting testing and manufacturing.
You will be working on our existing BMS with the primary focus on optimisation and continuous improvement of the design, whilst adapting the functionality to maximise pack performance in different deployments, closely collaborating with other teams to deliver high-performance systems and enabling deployment into real-world applications. Additionally, you will be involved in supporting the development and design of next generation cells and modules and their scale-up towards application/deployment.
You will primarily work within the battery pack electrical team, collaborating closely across engineering, product, application testing and commercial functions to translate innovation into deliverable products.
This is a rare opportunity to join a high-growth, entrepreneurial business at a pivotal stage. While experience in battery technologies is advantageous, we actively welcome candidates from adjacent fields - bringing fresh perspectives to complex engineering challenges. In return, we offer a world-class environment to develop deep expertise in next-generation energy storage.
Key responsibilities:
Responsible for the design and implementation of novel BMSs, from concept to detailed design, manufacture and validation.
Responsible for system-level battery pack electrical architecture design, from cell interconnections to AC load.
Responsible for battery pack wiring harness design and supplier engagement.
Collaborate closely with all parts of the business to support and understand how BMS strategy can improve cell performance.
Assist firmware/software engineers with specifications and general strategy.
Contribute across electronic engineering with the flexibility to adapt to evolving business and technical needs.
Collaborate on greenfield projects, proactively bringing forward ideas and taking ownership of their execution.
Responsible for creating and maintaining high-quality designs and engineering drawings.
Responsible for testing and validation at sub-system and system level.
Champion safe working practices, ensuring compliance with internal safety standards, training, and engineering best practices.
Requirements
You will have/be:
A degree in Electrical and Electronic Engineering, or a related engineering discipline; alternatively, demonstrable experience in a comparable role.
Experience in electronic hardware design and development, including analogue, digital and/or power electronic circuits.
Experience designing, developing and manufacturing Battery Management Systems (BMS).
Experience with power electronic topologies and their practical application.
Proficiency with ECAD tools such as Altium Designer or equivalent.
Hands-on experience working with electronic hardware, including prototype assembly, soldering, wire harness manufacture, PCB rework and laboratory testing.
Experience planning, executing and analysing hardware verification and validation activities.
Strong fault-finding, debugging and root cause analysis skills for electronic systems.
Experience producing clear engineering documentation, including schematics, bills of materials (BOMs), test plans and technical reports.
Ability to manage multiple concurrent projects while maintaining ownership and accountability for delivery against agreed deadlines.
Strong analytical skills, with the ability to interpret test data and communicate technical findings effectively.
Clear and structured communication skills, with the ability to present technical information to both technical and non-technical audiences.
Ability to work effectively within multidisciplinary teams and translate complex technical requirements into practical engineering solutions.
A proactive and collaborative mindset, with the confidence to challenge existing approaches and drive continuous improvement.
Ability to work independently and effectively in environments with evolving requirements and technical uncertainty.
