Who is Lightyear?

Lightyear is an innovative and progressive scale-up with one mission; offering clean mobility for everyone, everywhere! Lightyear originates from the multiple world champion of the Bridgestone World Solar Challenge® Cruiser Class, Solar Team Eindhoven. With Stella and Stella Lux this team developed a solar powered, 4 person, road legal car. Lightyear was officially established in 2016 aiming to make this groundbreaking technology accessible to everyone! In 2016 it started with 5 visionaries. At the beginning of 2018 Lightyear had grown to 40 highly motivated people. Today, Lightyear consists of nearly 150 employees and keeps on growing. Lightyear has its own production facility and a new office to be delivered in the summer of 2019. This growth will continue in the coming years. For that reason we are looking for talent and experience to strengthen the company and contribute in achieving our mission!

What will you do as Mechanical Engineer Motors?

You''ll be part of the In-wheel motor (IWM) system. The Motor Team at Lightyear is responsible for the design and development of the propulsion system of Lightyear One and develops the majority of the in-wheel motor (IWM) system in-house. IWM’s have strong advantages in terms of efficiency, mass, vehicle handling, packaging space compared to more conventional drivetrain architectures. Lightyear will develop a bespoke inverter, in order to optimize for maximum powertrain efficiency. Combined, it is a fundamental system for Lightyear as an EV solar car platform. Ultimately, it ensures independence, long range, reliability, minimum total cost of ownership over lifetime and all-road capabilities for the Lightyear One.

You will help develop the IWM system together with a highly cross-functional engineering team with backgrounds in: mechanical-, thermal-, software-, control-, electrical engineering, test- and vehicle dynamics engineering. The primary focus of the role is supporting the mechanical design of the in-wheel motor system: i.e. component packaging, definition of interfaces with electromagnetic components (rotor and stator) and interfaces with the vehicle dynamics subsystems (wheels and suspension). You will help drive and improve the mechanical design, with core engineering knowledge. You are responsible for sections of the motor design within the team (e.g. bearing systems and sealing methods) and will require expert skills in developing CAD models along with the associated 2D drawings for the manufacturers. A good experience and knowledge of manufacturing methods for series of mechanical parts is a key competency. Your job will consist of but is not limited to:

  • Create high quality 3D-models that can be integrated in the overall vehicle design
  • Develop and create 2D manufacturing drawings for the designed components.
  • Taking thermal and structural analysis (FEA) feedback results and helping to review the data to implement on the next iterations and improvements of the design.
  • Helping the team develop the current prototype motor system towards a series production.
  • Creating solutions that are both cost effective and reliable.

What do we expect from a Mechanical Engineer Motors at Lightyear?

To succeed in the dynamic world of Lightyear, pro-activity, professionalism, communication and adaptability are crucial. In addition, we are looking for someone with an ambitious attitude who learns from the past (tried and tested) but who is especially open to transforming new developments or ideas into the "tried and tested" of the future! You are also someone with a high sense of responsibility and a cooperative attitude. You like short lines of communication. You have excellent communication skills, you are a self starter with a ‘can do’ mentality. You can create and build from scratch, you are committed, punctual, quality minded, a team player, flexible, stress resilient and of course a fast learner. Furthermore you'll bring:

  • A Bachelor or Master degree in Mechanical Engineering or equivalent
  • At least 2 years of full-time professional experience with mechanical design of motor or propulsion systems (Formula Student, Solar Team or Hyperloop team is also valid)
  • Knowledge of rotary electromotors, motor design, systems design, structural analysis, materials science and heat transfer
  • Knowledge of design for manufacturing (DFM), design for assembly (DFA), Failure modes and effects analysis (FMEA) and developing a Bill of Materials (BOM) of designs
  • Experience developing a product from concept to production
  • 2-3 years hands-on experience with 3D modelling software (Catia preferably)
  • Strong communication skills, both verbally and written
  • Knowledge of relevant manufacturing processes and lightweight, recyclable and sustainable materials
  • Fluent in English (Dutch preferred)


  • You are comfortable and energized by working in a team with a wide variety of backgrounds and skill-sets. You welcome constructive feedback and different perspectives. You desire to truly understand the goals and needs of your teammates
  • You thrive in a fast-paced environment where several interdependent technologies are being developed simultaneously. You welcome the challenge of generating ideas and performing analysis based on inputs and requirements that are subject to change
  • Ability to make decisions, and effectively complete the given tasks and meet challenging deadlines with the set requirements

What can you expect from Lightyear?

In addition to a challenging role as Mechanical Engineer Motors, you also have the opportunity to work for a company with a real, honest and ambitious mission. This way you have the opportunity to make a huge impact on the future of mobility! In addition, we also offer:

  • A high degree of freedom and independence in your role
  • A role within a multidisciplinary team consisting of highly motivated, inquisitive and talented people with a broad diversity of experience
  • A role at one of the fastest growing technical companies in the Netherlands with accompanying opportunities
  • 40 vacation days a year. (based on full-time employment)
  • Excellent travel allowance that encourages the use of public transport
  • An interesting and balanced pension through Zwitserleven that is in line with the mission of Lightyear
  • The ability to participate via shares and to be involved in the growth and success of Lightyear
  • In addition to a dynamic working environment, there is time for relaxation during our already epic Friday afternoon drinks
