Electrical Engineer

Electrical Engineer Electrical Engineer (80-100%) Integration of inverter and energy storage systems Inesco AG · Location: Solothurn · Workload: 80–100 % · Start: by arrangement · permanent About us Inesco Energy is a young technology company. We develop and distribute stationary energy storage systems based on sodium-ion technology — a safe and resource-uncritical alternative to classic lithium storage. The system is supplemented by the Inesco Gateway: an interface platform that connects our systems with customers (via the own web monitor) and external EMS such as SolarManager or SmartFox. As a small team, we accompany our systems from design to testing to commissioning at the customer site. We offer storage solutions for households as well as applications in commerce, industry and agriculture – in the middle of a rapidly changing energy market. Our systems are already in use in Switzerland and in Germany – and we are consistently driving our expansion forward. Your role You will strengthen our technical team and independently take over the integration of inverter technologies into our storage systems — from design to parameterization to commissioning. In complex customer projects, you will develop technical solution approaches. At the same time, you are the technical interface to our software development: you advise the team regarding the Gateway platform, specify requirements from practice and validate new functions on the real system. Your work is versatile, technically demanding and has direct impact: you drive the energy transition forward. Your tasks Inverter integration: design, parameterization and commissioning of hybrid and battery inverters in interaction with our sodium-ion storage (AC and DC coupling, grid-parallel systems). Technical solution concepts: development of solution approaches in complex projects — grid connection, protection and safety concepts, norm compliance (NIN, local utility regulations, NA protection). Protocol integration: connection of internal components and external EMS via Modbus RTU/TCP, MQTT and other common protocols. Interface to software development: advice and assistance in the further development of the Gateway platform — bringing in requirements from the field, clarifying driver and protocol topics, testing new releases on the laboratory system. Set up, perform and automate tests: test stands in the laboratory, measurements on cells, modules and complete systems — execution and evaluation frequently via script (Bash, ). Field debugging and second-level support: take over escalations from support — analyze problems, reproduce and develop solutions, if necessary also on-site at the customer. Schema and bill of materials verification: check circuit diagrams, compare BOMs against the schemata, detect and correct inconsistencies. Documentation: record technical concepts, test reports and commissioning protocols in such a way that they are usable for customers, authorities and internal reviews. What you bring Completed training in electrical engineering, energy technology, mechatronics or embedded systems — Bachelor FH/University, dipl. Techniker:in HF or equivalent further education based on a vocational apprenticeship (e.g., Automatiker:in, Elektroniker:in or Elektroinstallateur:in EFZ) Good understanding of power electronics, ideally with practical experience with inverters, battery systems or photovoltaics Experience with communication protocols such as Modbus RTU/TCP; MQTT is an advantage Confident handling of Linux (configuration, shell, package management) and at least one scripting language — Bash and/or Ability to confidently read, check and plausibilize circuit diagrams and bills of materials Practical experience with measurement technology (multimeter, oscilloscope, current clamps, data logger) Knowledge of NIN and initial contact with grid connection topics (local utility regulations, NA protection) is an advantage Independent, structured way of working, analytical approach to troubleshooting and enjoyment of bridging the gap between hardware and software German business fluent, English good (data sheets, technical communication); driving license Cat. B for field assignments What we offer Independent tasks with real creative freedom — in a small team your work becomes immediately visible Short decision-making paths, flat hierarchies and a direct mentor from the technical management Responsibility over the entire product lifecycle: design, test, commissioning, after-sales Laboratory with current measurement and storage technology Flexible working hours, fair compensation and clear development perspectives in a growing product environment Application If at least 60 % of the above points apply to you, then send us your CV and a short motivation letter (. 1 page).
