Battery Engineer (Pack Design & Cell Characterization)

Job description

TYTAN Technologies The PACE is fast. The expectations are high. The contribution matters. Working at TYTAN is more than a job, this is a mission. We thrive, think big, and hold ourselves to the highest standard. Our mission and values guide everything we do, and we're looking for people who thrive on ownership, embrace challenges, and are energized by meaningful work. If you're motivated by impact and thrive in dynamic environments, you'll fit right in. At TYTAN , we aim to set a global standard in autonomous air defense with AI-driven, cost-efficient systems that counter unmanned aerial threats at scale. We protect people. We protect critical infrastructure. We protect Europe’s sovereignty. We are looking for a Battery Systems Engineer to lead the design, development, and validation of advanced low-voltage battery packs. In this role, you will be responsible for battery pack architecture, mechanical integration, thermal management, cell evaluation, electrochemical testing, and safety compliance. Working closely with cross-functional teams and external suppliers, you will drive projects from concept development through prototyping, testing, and production release, ensuring high-performance, reliable, and safe energy storage solutions. Your Roadmap to Make an Impact Pack design & mechanical integration: Design low-voltage battery packs, enclosures, cell modules, busbars and interconnects in CAD — from first concept through to release-ready drawings and BOMs. Thermal & structural layout: Develop thermal management concepts and validate them against mechanical loads, vibration and shock requirements of the target application. Cell selection & benchmarking: Evaluate and qualify cells from different suppliers; build the data basis for design decisions on energy density, power capability, cycle life and cost. Electrochemical testing: Plan, run and evaluate cell and module tests — capacity and rate characterisation, EIS, ageing and cycle-life campaigns, thermal characterisation — and derive design conclusions from the results. Test infrastructure: Set up and maintain test benches, fixtures and measurement chains; build repeatable test procedures and keep the data properly documented and traceable. Prototyping & validation: Build and instrument prototype packs, run the validation programme, and feed findings back into the next design iteration. Safety & standards: Support hazard and risk assessments, define protection concepts (fusing, isolation, venting, propagation resistance) and prepare packs for the relevant transport and product standards (e.g. UN 38.3, IEC 62133). Interface management: Coordinate technically with mechanics, electronics/BMS, manufacturing and purchasing, and act as the technical counterpart to external cell and component suppliers. Completed degree in engineering or natural sciences — electrical engineering, mechanical engineering, mechatronics, chemistry, physics or materials science. Roughly 3–5 years of hands-on experience in battery development, ideally with low-voltage packs for mobile or embedded applications. Solid understanding of lithium-ion cell chemistry and electrochemistry, cell-to-pack architecture and thermal behavior. Confident with CAD (e.g. Siemens NX, SolidWorks or CATIA); experience with design for manufacturing and joining technologies for cell contacting (welding, bonding) is a plus. Solid understanding of state estimation, balancing, thermal control and their interaction with pack hardware Practical experience with cell cyclers, climate chambers, EIS, data acquisition and general lab measurement technique is a plus. Comfortable evaluating test data with Python or MATLAB; basic familiarity with thermal or electrical simulation is welcome. Working knowledge of the safety, testing and transport standards relevant to lithium-ion batteries. Analytical, structured way of working, hands-on mentality in the lab, and the ability to work across disciplines in a small, fast-moving team. Languages: Fluent English; German is a plus. Nice to Have Experience with aerospace, UAV or other weight-critical applications Experience taking a pack from prototype to small-series production Why TYTAN? Build technology with real operational impact: Develop autonomous defence systems designed to protect lives and strengthen Europe’s security Shape scalable defence capabilities: Work on solutions built for mass deployment, cost efficiency, resilience, and reliable production at scale Contribute to networked air defence: Help integrate our systems into multi-layered defence architectures alongside sensors, command systems, and effectors Develop for real-world operations: Build capabilities together with end users and improve them continuously based on direct operational feedback Move fast and take ownership: Work in a focused, high-performance team where decisions are made quickly and individual contributions have immediate impact Define a new generation of defence technology: Join early and help shape the products, engineering standards, culture, and direction of a fast-growing deep-tech company Work with an international mission-driven team: Collaborate with experienced specialists united by the goal of creating sovereign and effective security capabilities for Europe Our Benefits Virtual stock options: Participate in our success through Virtual stock options (VSOPs) at the company's current valuation Monthly allowances: €106/month in flexible benefits including lunch discounts and EGYM Wellpass or shopping credit Regular health care events: Health check-ups, skin screenings, mental health workshops, and an annual vitamin infusion on us Referral bonus: Earn a reward when someone you refer joins the team Regular team events: On- and off-site activities to connect and celebrate together Corporate discounts: Exclusive employee discounts across a wide range of partner brands Flexibility : Flexible working hours and hybrid work model, plus a modern Munich office built for focus and collaboration About us At TYTAN, it is more than just a job; it is about embracing autonomy, personal growth, and purpose.
