Job Summary
- Own the end-to-end system architecture of the UPS product - topology selection (NPC back-to-back AC/DC DC/DC stages) power stage definition hardware/software partitioning and interface specification.
- Translate business and customer requirements into a coherent certifiable technical specification. When requirements conflict or are ambiguous you resolve them.
- Lead technology trade-off studies and make architecture decisions with full accountability -including choices that will define the product for its entire lifecycle.
- Define and evolve the technology roadmap starting with the UPS programme and growing to cover the companys broader inverter product portfolio.
- Act as the highest technical authority on the programme - the Control System Engineer Hardware Engineer and Embedded SW Engineer work alongside you not above you.
- Define system-level interfaces integration milestones and technical review gates. You set the architecture; the team executes within it.
- Drive alignment across disciplines (HW SW control mechanical) and escalate or resolve conflicts at the system level.
- Define the validation and test strategy - SIL/HIL coverage system-level test plans and commissioning approach - and own it through to field deployment.
- Architect the product for compliance with relevant standards from day one - not as an afterthought. Key standards include IEC 62040 CE marking EN 50091 and power electronics equivalents.
- Lead the certification process: define the compliance strategy manage documentation and represent the programme with certification bodies.
- Assess applicability of marine certification (GL LR ABS) as the portfolio evolves - this is a future-phase requirement not a day-one deliverable.
- Lead independent technical meetings with customers - presenting architecture resolving technical issues and translating customer requirements into engineering constraints.
- Support Sales and Marketing as the technical authority in pre-sales conversations proposals and demonstrations.
- Represent the company in supplier and component selection discussions where architecture decisions drive procurement.
- Drive system-level FMEA (DFMEA PFMEA) FTA and functional safety analysis. Own the risk register for technical decisions.
- Ensure all architecture decisions are documented traceable and defensible to certification bodies and customers.
- Contribute actively to intellectual property creation - patents technical disclosures and know-how documentation.
- Minimum 78 years of hands-on power electronics product development - with clear evidence of making architecture decisions not just implementing them.
- Proven track record of taking a power electronics product from concept through to manufacturing launch. If you have never delivered a complete product to market this role is not the right fit.
- Solid command of power converter topologies: NPC ANPC back-to-back AC/DC DC/DC multi-level converters. You can discuss trade-offs between topologies without preparation.
- System-level understanding of power converter control - current loops voltage control DC-link management grid behaviour. You do not need to write the control code but you must understand what the Control System Engineer is building and why.
- Ability and appetite to operate as the sole technical authority on a greenfield programme - making decisions living with their consequences and iterating quickly.
- English B2/C1 (customer-facing role) and Polish (required for internal collaboration).
- Knowledge of power electronics certification processes (IEC 62040 CE EN 50091 or equivalent product class) - you have been through at least one product certification cycle.
- Experience with system-level FMEA/DFMEA functional safety analysis (IEC 61508 or equivalent) and risk management in a power electronics context.
- Familiarity with embedded control platforms used in power converters (TI C2000 STM32 DSP-based controllers) - enough to specify requirements and review implementations.
- Knowledge of industrial communication protocols (CAN EtherCAT Modbus SPI UART) at the level needed to define system interfaces.
- Experience defining validation strategies - SIL HIL system-level testing - and building test infrastructure from scratch where necessary.
- Background in grid-connected converter behaviour and grid code requirements (LVRT/HVRT fault ride-through reactive power support).
- MATLAB/Simulink for system-level modelling and simulation.
- FPGA-based control platform experience.
- Marine certification exposure (GL LR ABS) - relevant for future portfolio expansion.
- Full technical ownership of a greenfield product - your architecture decisions will define this UPS for its entire commercial life. This level of authority is rare.
- A clear growth path: the UPS programme is the entry point; the roadmap includes a broader inverter portfolio that will need the same architectural leadership.
- Work in an international R&D environment on a high-complexity product with real-world industrial and energy applications.
- Stable permanent employment (UoP) in a company with an established global market position.
- Attractive compensation commensurate with experience.
- Hybrid model - 3 days on-site 2 days remote.
