System Engineer Power Eelectronics

• Define and own the overall system architecture for MW-scale UPS and inverter systems, including topology selection, power stage definition, and hardware/software partitioning.
  
• Develop system-level requirements and technical specifications derived from customer, regulatory, and business inputs.
  
• Lead topology and technology trade-off studies (e.g. NPC, back-to-back, AC/DC, DC/DC stages) and make architecture decisions in collaboration with the engineering team.
  
• Own the product technology roadmap, starting with the UPS programme and expanding to the broader inverter product portfolio.
  

• Carry technical responsibility for project progress, coordinating the work of the Control System Engineer, Hardware Engineer, and Senior Embedded SW Engineer.
  

• Drive alignment across engineering disciplines (HW, SW, control, mechanical) to ensure consistent system integration and architecture compliance.
  
• Define and manage system-level interfaces, integration milestones, and technical review gates throughout the product development lifecycle.
  
• Support definition of validation and test strategy at system level, including SIL/HIL coverage planning.
  

• Ensure the product architecture is designed for compliance with relevant power electronics standards (IEC 62040, CE marking, EN 50091, and equivalent).
  
• Drive and coordinate the product certification process, liaising with certification bodies and managing documentation requirements.
  
• Assess applicability of marine certification standards (GL, LR, ABS) for future product variants as the portfolio evolves.
  

• Lead independent technical meetings with customers — presenting system architecture, discussing requirements, and resolving technical issues.
  
• Support Sales and Marketing in pre-sales technical activities, proposals, and customer demonstrations as required.
  
• Represent the engineering team in supplier technical negotiations and component/subsystem selection decisions.
  

• Drive FMEA (DFMEA, PFMEA), FTA, and functional safety analysis at system level throughout the product development process.
  
• Identify, assess, and mitigate technical risks across the full product lifecycle — from concept through field deployment.
  
• Ensure system-level design decisions are traceable to requirements and documented to the standard required for certification and IP protection.
  
• Contribute to intellectual property creation (patents, technical disclosures).
  

Requirements

• Bachelor's or Master's degree in Electrical Engineering, Power Electronics, Energy Engineering, or a related field.
  
• Minimum 7–8 years of hands-on commercial experience in power electronics product development.
  
• Proven track record of delivering complete power electronics products from concept through manufacturing launch - this is an absolute requirement.
  
• Background in industrial power electronics applications - UPS, industrial drives, wind/solar inverters, traction converters, or equivalent high-reliability power systems.
  

• Solid understanding of power converter topologies used in industrial and energy applications (NPC, ANPC, back-to-back, AC/DC, DC/DC, multi-level converters).
  
• System-level understanding of power converter control strategies (current control, V/F, DC-link regulation, grid code compliance) - implementation ownership lies with Control System, Hardware, Testing and Embedded SW Engineers, but architectural oversight is required.
  
• Familiarity with power electronics certification standards and processes (IEC 62040, CE, EN 50091, or equivalent product class).
  
• Experience with system-level FMEA/DFMEA, risk management, and functional safety analysis (IEC 61508 or equivalent).
  
• Knowledge of communication protocols relevant to industrial power systems (CAN, EtherCAT, Modbus, Ethernet).
  
• Ability to define validation strategies including SIL, HIL, and system-level testing approaches.
  

• Ability to lead and coordinate a small cross-functional engineering team with technical authority - not a line management role, but genuine technical ownership.
  
• Strong system-level thinking with the ability to make and justify architecture decisions under uncertainty.
  
• Experience conducting independent technical meetings with customers and external stakeholders.
  
• Proficiency in technical documentation, requirements management, and engineering process tooling.
  
• Self-directed working style - the role requires the ability to operate autonomously after an initial onboarding period of 1–3 months.
  

• English: minimum B2/C1 - required for customer meetings, documentation, and team communication.
  
• Polish: required.
  

• Direct experience with UPS systems (architecture, topologies, operating modes, grid interaction, IEC 62040 / EN 50091) - candidates with UPS background will be prioritised.
  

• Background in grid-connected converter behaviour and grid code requirements (LVRT/HVRT, reactive power support).
  
• MATLAB/Simulink experience for system-level modelling and simulation.
  
• Familiarity with FPGA-based control platforms used in high-power converters.
  
• Experience with marine or offshore certification standards (GL, LR, ABS).
  

Benefits

• A greenfield technical leadership role - rare opportunity to define system architecture and technology choices from day one.
  
• Work within an international environment on an innovative UPS programme with a clear path to broader portfolio ownership.
  
• Stable employment in a company with an established global market position.
  
• Professional development opportunities and access to state-of-the-art R&D infrastructure.
  
• Attractive compensation package commensurate with experience (UoP).
  
• Hybrid work model —-3 days on-site.
  
• Limited travel commitment: 2-4 trips per year, maximum 2-3 weeks in total annually.
