Accurate real-time observation and prediction of the battery’s State of Function (SoF), the energy and power actually accessible for safe flight and landing, is the safety-critical output of the battery system, and the basis for pre-flight planning, in-flight energy management, and the energy information presented to the crew.\nSoF is built on the underlying battery states that your algorithms observe and predict: state of charge (SoC), state of health (SoH), state of power (SoP), state of energy (SoE), and state of balance (SoB). Erroneous observation or prediction of SoF is classified as a catastrophic condition, since it can lead the crew to commit to a flight or an approach the battery cannot support. This makes the function certification-critical and places exacting demands on the accuracy, robustness, and verifiability of every algorithm you deliver.\nAs a Senior Battery Algorithms Engineer (all genders), you will join the VÆRIDION Technology team and take ownership of the development and validation of the state observers, estimators, and predictors that determine SoF for our lithium-ion propulsion battery systems.\nThis is a hands-on senior role in which you lead the modeling, simulation, algorithm development, test-data analysis, and validation behind these states, and set the methodology the team works to.\nYour work will shape the high-voltage battery system at the center of VÆRIDION’s electric propulsion architecture and carry it through to certification.\nYour Day-to-Day:\nOwn the end-to-end development and validation of battery state observers, estimators, and predictors for SoF, SoC, SoH, SoP, SoE, and SoB across cell, cell-bank, and pack level\n\nParameterize multi-RC equivalent-circuit models (OCV, R0, RC pairs, hysteresis, thermal, and aging effects) from cell supplier data, virtual and physical test benches, and HiL rigs\n\nDesign, implement, and validate estimation algorithms such as Kalman filters (EKF/UKF/dual-UKF/SKF), particle filters, observers, and data-driven/ML methods, while respecting the certification limitations of ML-based approaches\n\nDevelop mission-aware predictors that ingest flight-profile and navigation data to predict SoF until safe landing, and compute the energy margin, the predicted surplus SoF at destination, and the SoF trend presented to the crew, updating on diversion, altitude, speed, and ambient changes\n\nDevelop aging and degradation models and Remaining Useful Life (RUL) prediction, and validate the SoH algorithm against the applicable end-of-life criteria across representative mission and durability profiles\n\nEnsure the algorithms align with ED-289 requirements for state observers and predictors and ED-309 methodologies for energy level information to the crew, and are consistent with the “Manage Energy” functional breakdown\n\nEnsure the algorithms meet functional-safety expectations for a DAL B function: deterministic and bounded execution time, reproducibility, uncertainty bounds on outputs, plausibility checks, built-in test, and malfunction and fault detection\n\nDerive, document, and trace algorithm requirements from ED-289/ED-309 and system-level functional analysis, and maintain traceability into the real-time battery management software specification using a model-based design approach\n\nSupport the real-time embedded realization of estimators and predictors on the pack, lane, and central control units (fixed-point implementation, Simulink code generation, MISRA C) and validate them on HiL setups\n\nDefine the test and analysis strategy for virtual and physical battery test benches and HiL rigs, and analyze cell, cell-bank, and pack-level data to evaluate algorithm accuracy, stability, and robustness across temperature, aging, and usage variability\n\nSet the standard for documentation of methods, assumptions, and validation results\n\nLead collaboration with cell engineering, BMS software, test, HV/LV electrical systems, and certification teams\n\nYour Profile:\nBachelor’s or Master’s degree in Electrical Engineering, Aerospace Engineering, Mechanical Engineering, Applied Mathematics, Control Engineering, or a related field\n\n5+ years of professional experience in battery state estimation, control systems, or embedded algorithm development\n\nStrong command of state estimation and control theory: Kalman filtering (EKF/UKF/dual-UKF/SKF), particle filters, observers, and system modeling, with an awareness of data-driven and ML methods and their certification constraints\n\nSolid battery domain knowledge: lithium-ion electrochemistry, equivalent-circuit and thermal models, aging and degradation mechanisms (capacity fade, resistance growth, lithium plating), OCV hysteresis, and cell-bank-level state granularity\n\nProficiency in Matlab/Simulink and Python, with familiarity with C/C++, fixed-point implementation, Git, and CI/CD\n\nExperience with real-time simulation, HiL testing, and embedded systems\n\nFamiliarity with aerospace functional safety and certification: DO-178C/ED-12C and the DAL concept, requirements-based verification and validation, MBSE and model-based design, and relevant battery and energy standards (ED-289, ED-309, DO-311A, SAE AIR6897); DO-160 environmental awareness is a plus\n\nAnalytical mindset, strong attention to detail, the ability to own deliverables end-to-end, and clear technical documentation skills\n\nWe recognize that women and other under-represented groups are often overlooked in our industry. If you’re excited about this role but don’t meet every listed qualification, we still encourage you to apply. Talent and potential can’t always be captured in a checklist.\nWhy us?\nBe part of an ambitious team determined to shape the future of aviation.\n\nWe are an in-office company, but we value flexibility and trust employees to manage their schedules responsibly. This may include occasional remote work or adjusting hours to accommodate personal commitments.\n\nSubsidized EGYM Wellpass membership: your (mental) health is important for us.\n\nEnjoy a subsidized lunch with a 5€ company contribution per meal on office days.\n\nBecome a part of our success with virtual stock options.\n\nChoose the option that suits your needs: either a free charging station for your electric car or a public transport job ticket as part of the Deutschlandticket.\n\nLease a high-quality bicycle or e-bike through our JobRad program and benefit from tax advantages. Whether for your daily commute or personal use, enjoy more mobility and sustainability.\n\nPension scheme to support your long-term financial security.\n\nWork in one of our offices in Munich or Delft. Enjoy the modern Balan Campus in Munich or work inside the aerospace ecosystem at TU Delft.\n\nBoost your professional as well as personal growth executing your own ideas and independent projects.\n\nJoin our internal social events and retreats (e.g. cooking, game nights, sports).\n\nVÆRIDION was founded in 2021 to transform regional air travel with the Microliner, a 100% electric commercial aircraft.
