Manufacturing Test Engineer

Lyten is leading an industrial revolution through Lyten 3D Graphene™, a breakthrough supermaterial unlocking a new generation of products — from lithium–sulfur batteries and energy storage systems to concrete admixtures, lightweight composites, and next-generation sensors that are revolutionizing industries. Together, these innovations are making a massive global improvement and driving real-world impact across energy, mobility, construction, and defense.

At Lyten, we believe the most meaningful careers begin with purpose — and with people who want to make a difference. We’re not just developing advanced supermaterials — we’re about to change the world as we know it, reshaping how energy is stored, how products are built, and how progress is made.

We’re entering an exciting growth phase, scaling production across the U.S. and Europe and expanding our team of engineers, scientists, and innovators.

Apply now to join our team and be part of something bigger than yourself — where collaboration, creativity, and purpose come together to build the technologies that will define the next century.

We are looking for a Manufacturing Test Engineer to join the core team responsible for launching a new production line. After the start-up phase, you will take full ownership of assigned electrical test stations and processes, ensuring their reliability, performance, and continuous improvement.

Your role

At the beginning, you will be part of the team responsible for developing and commissioning electrical test systems for a new production line.

Once the line is operational, you will take the role of test process owner, responsible for the stability, capability, and performance of assigned electrical test equipment and processes — with a strong focus on OEE and production sustainability.

Your responsibilities

• Define and develop electrical test equipment and process requirement specifications

• Play a key role in production line launch and ramp-up, achieving targeted MSA and process capabilities

• Lead equipment fine-tuning, debugging, and test adjustments during commissioning and ramp-up phases

• Review Design Failure Mode and Effect Analysis and identify manufacturing risks

• Translate product electrical requirements into robust manufacturing test processes

• Design and implement new testing technologies to improve performance and reduce equipment consumable usage

• Support production ramp-up by ensuring machine capability, process capability, and measurement system analysis (MSA)

• Define process validation guidelines and lead commissioning activities during FAT and SAT

• Own and drive development of Process Failure Mode and Effect Analysis

• Create and maintain Standard Operating Procedures, Work Instructions, defect descriptions, and reaction matrices

• Characterize electrical tests, define critical parameters, and establish monitoring using SPC

• Execute Design of Experiments to optimize test conditions and improve production KPIs

• Train test and maintenance technicians

• Ensure and promote 5S standards within the production environment

• Support capital improvement projects related to test equipment and production performance

What we are looking for

• Degree in Electrical, Electronics, or Mechatronics Engineering (or similar field)

• 4+ years of experience in electrical or battery testing within a manufacturing environment

• Experience with high-voltage testing and understanding of Li-Ion battery protection fundamentals

• Proven experience developing and implementing electrical test processes in production

• Experience writing technical documentation, including:

  • requirement specifications

  • functional designs

  • test cases and test records

  • validation protocols

• Strong analytical skills and the ability to troubleshoot complex hardware and software systems

• Passion for solving complex technical problems in simple and innovative ways

• Quality- and customer-oriented mindset

• Experience working in multicultural environments within industries such as battery, electronics, semiconductor, or automotive

Technical skills

• Knowledge of Lean Manufacturing, Six Sigma, and 5S

• Problem solving using 8D methodology and Ishikawa diagrams

• Strong experience with NI LabVIEW and/or NI TestStand and/or MATLAB

• Programming knowledge in Python, C, C++, C#, or SQL

• Understanding of communication protocols such as CAN, Ethernet, RS-232

• Familiarity with test scripting languages and automated test stations (e.g., Keysight BTI, Teradyne)

What will make you successful in this role

You are the kind of engineer who enjoys working where hardware, software, and manufacturing meet.

You can move seamlessly between test architecture design, debugging electronics, analyzing data, and improving production performance.

And you believe that the best test system is the one that not only detects problems — but helps prevent them.

Factory is located at Gdańsk, Stogi.

Min. salary for this position starts at 10 000 PLN gross.
