Thermal Systems & Mechanical Engineer

ppOur Team. /p pA strong team is the DNA of our company. /p pOur team brings together experts in Mechanical Engineering, Software, E/E, Manufacturing, Homologation, Testing, Purchasing, Business Development, and Sales Marketing. At Flux, we work as equals and foster a highly motivating environment shaped by shared ownership, flat hierarchies, and a strong team spirit. Here, you will not only develop your skills, but also make a real impact. Join our team and help shape the mobility of tomorrow. /p h3Your role. /h3 pWe are looking for an experienced Thermal Systems Mechanical Engineer to take technical ownership of the thermal management of our electric light commercial vehicles and the mechanical design that goes with it. /p pIn this role, you own the thermal architecture of the vehicle: battery cooling and heating, power electronics and e-motor cooling, cabin climate, and the coolant and refrigerant circuits that connect them. You size these systems, design and integrate the mechanical hardware (pumps, valves, heat exchangers, lines and mounts) and make sure they work together across the full operating range, from alpine winters to fully loaded summer duty cycles. /p pYou work closely with our mechanical, electrical and software teams. You define the thermal requirements and operating strategy together with software, and support development from concept through simulation and calculation to verification in the vehicle and in the field. /p pAt Flux, you will work in a small team with short decision-making paths. You take ownership of technical decisions early and directly shape the architecture of our vehicles. /p h3What you can contribute. /h3 ullipTake technical ownership of the vehicle's thermal architecture: battery thermal management, power electronics and e-motor cooling, cabin HVAC, and the associated coolant and refrigerant circuits. /p /li /ul ullipSize and design cooling and heating systems, including pumps, valves, radiators, chillers, heat exchangers, expansion tanks, lines and heat pump and refrigerant circuits. /p /li /ul ullipCarry out thermal sizing and simulation (1D system simulation and, where needed, CFD) and correlate models against component and vehicle test data. /p /li /ul ullipDesign and integrate the mechanical hardware of the thermal system into the vehicle (packaging, mounting, routing and interfaces to the vehicle structure) together with the design team. /p /li /ul ullipDefine the thermal requirements and thermal operating strategy together with the software team. /p /li /ul ullipPlan and lead thermal verification and validation: component tests, climatic-chamber testing and on-vehicle testing in hot and cold conditions, in collaboration with external partners. /p /li /ul ullipWork with suppliers of thermal components (compressors, pumps, heat exchangers, HVAC units) on selection, specification and validation. /p /li /ul ullipSupport aftersales and the field team with thermal-related field issues and root-cause analysis. /p /li /ul ullipAnalyse test and field data to continuously improve the thermal and mechanical design. /p /li /ul h3How you will succeed in this role. /h3 ullipDegree in mechanical engineering, automotive engineering, mechatronics, process/energy engineering or a comparable discipline. /p /li /ul ullipAt least 5 years of industry experience in thermal systems or thermal management, ideally in automotive or a comparably demanding industry. /p /li /ul ullipPractical experience with vehicle thermal management topics such as battery cooling, HVAC/climate, refrigerant circuits or heat pump systems. /p /li /ul ullipExperience with thermal and 1D system simulation tools (e.g. GT-SUITE, KULI, Simcenter Amesim or Simscape) and with correlating models to test data. /p /li /ul ullipSolid mechanical design skills and a good understanding of fluid systems e.g. pumps, valves, heat exchangers and coolant/refrigerant circuits. /p /li /ul ullipExperience working with suppliers and development partners. /p /li /ul ullipAbility to take technical ownership and systematically develop complex systems. /p /li /ul ullipEnjoy working across disciplines in a pragmatic, fast-moving team. /p /li /ul h3Your environment. /h3 pAt Flux, we develop electric commercial vehicles in small, highly responsible teams. Our vehicles are already operating in the real world, on construction sites, in cities and in the daily operations of our customers. /p pThat means decisions are made close to the product. Engineers take responsibility for their systems throughout the entire development cycle, from concept and testing through to issues seen in the field. /p pIf you enjoy developing robust thermal and mechanical solutions, taking ownership and working in an environment where execution matters more than hierarchy, this role is a good fit for you. /p pAbout Flux. /p pFlux Mobility AGwas founded in April 2021. Our mission is to develop high-quality light commercial vehicles with innovative, emission‑free drivetrain technologies and to electrify specialist vehicles in Winterthur. /p pOur vehicles are built on a flexible platform concept that enables the direct replacement of diesel vehicles on a one-to-one basis. In doing so, we are helping to drive the sustainable transformation of industrial mobility and enabling companies to realise the full potential of electric mobility. /p /p #J-18808-Ljbffr
