Rimac Energy applies that same performance engineering to grid-scale battery storage, developing the SineStack Battery Energy Storage System (BESS) alongside an in-house Battery Management System and Battery Intelligence software platform. Headquartered in Zagreb with a manufacturing and innovation site in Witney, UK, the team is scaling fast as it moves from pilot deployments into full-scale European manufacturing.\nThe Role\nWe're looking for a Battery Intelligence Engineer to own how we understand our cells, from selecting and testing them, to analysing how they perform and age in the field. You'll be a hands-on engineer, just as comfortable with the physical testing of cells as you are when delving into the data.\nThe role requires knowledge of the technical performance aspects of lithium-ion batteries, from understanding the requirements around selecting appropriate cells for a product, to knowing how to validate our advanced SoC and SoH algorithms on a real system.\nKey Responsibilities\nCell Testing & Selection\nEngage with cell suppliers on their latest offerings and future cell roadmaps, shortlisting candidate cells for testing.\nPlan and run cell testing, covering all different aspects of performance from electrical, mechanical, thermal, ageing, and safety.\nRecommendations of which cell to select for each product, backed by the test data and the needs of the project.\nData Analysis\nAnalysis of cell test data and the generation of test reports to highlight a cell’s performance characteristics.\nTracking selected cells through module and rack build, reviewing the build and test data at each stage to ensure consistent and predictable performance.\nFollow the cell's operation in the field, using fleet data to spot trends in performance, safety and ageing.\nAlgorithm Validation\nCreate test plans to validate our algorithms and models, across embedded, edge, and cloud.\nDesign test rigs to validate our cells and modules in unique ways to mimic the real-world environment and not just a static lab.\nLead data generation and analysis, comparing results against model outputs and flagging where they diverge.\nSupport degradation assessments and lifetime optimisation.\nTechnical Expertise\nAct as a technical expert on current and future lithium-ion battery technology.\nConsult with stakeholders on the impact of the BESS design on the performance of the cell.\nWhat We're Looking For\nEngineering or STEM degree (Bachelor's or Master's), or equivalent experience.\nStrong knowledge of lithium-ion cell behaviour, including performance, safety and ageing.\nHands-on battery testing experience, including test equipment and data acquisition.\nExperience designing and building test rigs.\nPython and/or MATLAB for analysing test and field data.\nUnderstanding of how SoC and SoH estimation works and how to validate it on real products.\nClear communication and a collaborative, cross-functional working style.\nNice to have\nExperience working directly with cell suppliers on cell selection.\nExposure to module or rack build and integration.\nKnowledge of battery safety standards and regulations.\nPython data engineering experience.\nPhD or research-level background in electrochemistry or battery physics.\nWhat Rimac Energy Offers\nThe chance to shape the battery intelligence behind SineStack as it scales into full European manufacturing.\nA fast-paced, engineering-driven culture where practical problem-solving and initiative are genuinely valued.\nAn educational budget and continuous development, with exposure to rapidly evolving energy and power electronics technology.\n26 days' annual leave plus 8 public holidays.\n10 days' fully paid sick leave and 5 days' paid marriage leave.\n4 months' paid maternity leave and 2 weeks' paternity leave.\nCompany pension scheme with auto-enrolment.\nAXA and Medicash private medical insurance for you and your immediate family.\nService awards, a remote working day by agreement, and a pet-friendly office with relaxation zones and daily fresh fruit. \nHow to Apply\nSubmit a CV and a brief cover note outlining relevant battery testing, model validation or analytics experience.\nRimac Energy is an equal opportunity employer and welcomes applications from all qualified candidates.","description_format":"text","description_chars":4422,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[]},"benefits":["Annual
