Project Engineer in London

Full-time / London / Hybrid - 3 days in office

IONATE is a deep technology scale-up building the technology backbone for smart grids. Our team is looking for a Project Engineer responsible for hands-on engineering, project management, and site-based troubleshooting across the entire product lifecycle – from concept and prototyping to pilot deployments and commercial rollouts. We’re looking for someone who is comfortable working in a fast-paced start-up environment where priorities can evolve rapidly, and individuals are expected to take ownership beyond their immediate responsibilities. This position will involve travel within the UK and internationally, often at short notice, to customer sites and project locations for varying durations. You will need a holistic approach to engineering, with strong technical judgement, practical problem-solving skills and well-grounded engineering experience. Importantly, you will contribute to live ongoing projects and test activities and work with the team to continue developing our HIT technology.

What you will do:

• Project Ownership and Execution: Take ownership of technical workstreams and project deliverables, coordinating activities across engineering, manufacturing and suppliers. Lead or support site commissioning activities, coordinating multiple stakeholders to ensure safe and successful energisation and testing. Drive issues through to resolution, balancing technical, schedule and commercial considerations. Ensure that projects are delivered in scope, on time working in tandem with the project manager. Be involved in customer, supplier, and partner-facing conversations at each stage of the project lifecycle to ensure technical alignment. Monitor project status, report technical and schedule progress, and anticipate issues to inform risk management reviews and decisions. Participate in supplier management, logistics, procurement, and quality assurance for critical components. Promote a strong safety culture and ensure compliance with site, customer and company health and safety procedures.
• Technical Support and Engineering: Support the development, integration and validation of IONATE's technology through laboratory testing, field trials and commercial deployments. Work closely with engineering teams to translate product designs into robust, installable and maintainable solutions for deployment in customer networks. Coordinate technical activities across hardware, software, controls and power electronics teams to ensure efficient project execution and successful delivery. Produce and maintain technical documentation, engineering drawings, installation packs, commissioning procedures and test reports. Support requirements definition, system integration, interface management and verification activities throughout the project lifecycle. Troubleshoot technical issues across hardware, software, controls and communications systems, both remotely and on-site. Contribute to product and process improvements by capturing lessons learned from testing, commissioning and operational deployments.
• Site-Based Engineering and Travel: Willingness to travel extensively within the UK and internationally (typically 20-40%, but potentially higher during installation and commissioning periods). Conduct site surveys and work with customers to integrate our solution into their operations, adapting quickly to project scope changes. Perform functional and acceptance testing, commissioning, installations, and post-delivery troubleshooting across all projects. Collect field data and lessons learned to inform design improvements, commissioning procedures and future product development.

Requirements:

• Bachelor’s or Master’s degree in Electronics, Electrical, Power Electronics or Mechatronics Engineering.
• Experience with transformers, high power/grid connected inverters, substation design or any grid-interfaced, high-power Power Electronics hardware product is highly valued.
• Experience travelling for site-based project work for site surveys, SAT, FAT, installation and commissioning.
• Experience coordinating multidisciplinary engineering projects and using project management documentation and ERP tools such as Confluence, Jira, MS Project, AutoCAD, SAP or equivalent.
• Strong verbal and written communication skills for both technical and non-technical audiences.
• Comfortable working independently with minimal supervision and willing to travel extensively as required.
• Familiarity with commissioning, safety standards, and on-site troubleshooting especially in hardware-heavy environments.
• Experience working with utilities, network operators, industrial customers, EPCs or renewable energy developers would be advantageous.

Benefits:

• Employee Option Plan: You get equity in IONATE, so as we succeed so do you.
• Private Medical & Dental Insurance: From day one, we provide you with full, comprehensive private medical and dental cover through Bupa. You also have the option to add any dependents to your cover.
• Company pension: a flexible, and sustainable pension product to help you plan for your future.
• Career Development: It’s important to us that you have the opportunity for ongoing professional development and career growth. You will receive an annual budget for professional development and work with your team to set and reach goals every year.
• Flexible working schedules: You will be based in our modern West London offices and have the flexibility for hybrid work-from-home arrangements.
• Cycle to Work Scheme: Low carbon travel is important for everyone, so we have in place a cycle scheme to help you purchase a bicycle.
• Slow travel: We believe in a low carbon future, so if you wish to travel by a lower carbon method – but it takes much longer than flying - we will give you an extra 2 slow travel days per year.
