About us
We are a technology powerhouse that designs, engineers, and manufactures the world's most advanced automotive technology and hypercars. Bytes to bolts, Rimac is where everything happens.
Our teams develop and produce both hardware and software solutions for our flagship, record-breaking hypercar, the Nevera, as well as for other automotive manufacturers’ vehicles. Working on technology solutions for partners such as Porsche, Hyundai, Aston Martin, Koenigsegg, Automobili Pininfarina, and others, gives Rimac a unique position of a technology leader in the high-performance electric vehicle industry. The stakes are high.
As a fast-moving company, we nurture a high-performing culture. If you are interested in joining, you must be prepared for relentless learning, adapting, and embracing new technologies. We expect an easy-going person, but also self-driven, entrepreneurial, and highly independent in their work, that will enjoy rising to the challenge and have fun pushing the limits of technology.
Our expectations are high. And we can only achieve our goals with the dedication and collaboration of our exceptional team. Our ambition is to deliver and go the extra mile. We need to expand our already industry-leading team, find the best people, and lead the charge.
The Prototype Integration Technician is a hands-on, electrically biased technician/engineer who leads and contributes to the design, build, commissioning, and testing of low-volume prototype power electronics and energy systems at Rimac Energy.
The role operates at the intersection of electrical engineering, mechanical integration, and practical build, supporting the development of inverters, grid-connected systems, and associated energy storage hardware across early prototype, validation, and pre-production phases.
The successful candidate will be comfortable building and integrating real hardware, designing and assembling test rigs, commissioning systems safely, diagnosing faults, and providing clear technical feedback into the wider engineering organisation. While battery assembly experience is advantageous, the primary focus of the role is on inverter systems, grid interfaces, and electrical system integration.
Responsibilities
Prototype Build & Integration
Build, assemble, and integrate low-volume prototype systems, including inverter-based and grid-connected energy systems
Carry out mechanical and electrical assembly of prototype hardware, enclosures, sub-assemblies, and wiring looms
Support battery module and pack integration where required, including mechanical assembly, electrical connections, and instrumentation
Translate schematics, CAD models, and design intent into fully functional prototype hardware
Test Rig Design & Commissioning
Design, plan, and build bespoke test rigs to support functional, performance, and validation testing
Commission electrical systems safely, including power-up sequences, interlocks, and protection systems
Configure and connect test equipment such as power supplies, loads, measurement equipment, and data acquisition systems
Support inverter testing, and system-level validation activities
Testing, Fault Finding & Debug
Execute functional, electrical, thermal, and integration testing on prototype systems
Diagnose and troubleshoot electrical, mechanical, and system-level faults
Work methodically through issues, proposing and implementing practical solutions
Capture test results, observations, and build feedback to inform design improvements
Collaboration & Engineering Feedback
Work closely with electrical, mechanical, firmware, and systems engineers to resolve integration challenges
Provide hands-on feedback into design for manufacture, assembly, serviceability, and testability
Support early development builds through to validation and pre-production activities
Contribute to prototype build schedules and development planning
Process, Safety & Continuous Improvement
Develop and maintain build instructions, test procedures, and standard operating procedures
Ensure compliance with laboratory safety standards, electrical safety practices, and risk assessments
Maintain a clean, organised, and professional prototype build and test environment
Continuously improve prototype build efficiency, robustness, and repeatability
Requirements
Technical Background
Electrically biased engineer/technician with strong practical experience in real hardware build and integration
Competent in mechanical assembly, including fastening, tolerancing, enclosure build, and hands-on fabrication
Confident working with schematics, wiring diagrams, and basic mechanical drawings
Practical Experience
Proven experience building and commissioning prototype or low-volume systems
Experience with inverters, power conversion systems, or grid-connected equipment
Experience designing and assembling test rigs or experimental setups
Strong fault-finding and debugging capability across electrical and mechanical domains
Comfortable using hand tools, electrical tools, and standard workshop equipment
Battery assembly experience (cell, module, or pack level) is advantageous but not essential
Exposure to high-voltage or high-power systems is beneficial
Qualifications
Apprenticeship and/or Degree in Electrical Engineering, Electronic Engineering, Mechanical Engineering, or a related discipline
Equivalent practical, hands-on industry experience will be considered
Evidence of hands-on engineering outside formal employment (hobby projects, vehicle builds, electronics projects, etc.) is strongly valued
