Key Skills

Job Description

At Lightyear we are working on a family of power converters to convert solar energy from PV panels on vehicles to their batteries. The converter range consists of LV variants, HV variants and a multi-port variant that is able to convert energy from multiple solar panels to both LV and HV batteries. By intelligently combining several functions, this topology allows for a reduction in component count and improvement in efficiency. What will you do as a Software Engineer? At Lightyear we are developing a full in vehicle solar energy system. In addition to the solar panels, this includes the power electronics to convert solar energy into useful energy for the vehicle as well as extensive data analytics to optimize our system per vehicle in a data driven way. Specifically, you will: Develop high-quality, autonomous firmware for our highly efficient power converters using (async) Rust. Leverage modern real-time stream processing to monitor the performance of our solar panels and power converters, feeding data to real-time dashboards and our mobile app. Ensure all development adheres to strict quality and safety processes (ISO 26262 compliant) as we prepare for prototype projects and small series production. Take full ownership of your tasks: figure out the details, gather necessary context, research the domain, and deliver code that is truly production-ready before it even hits the review stage. Actively participate in rigorous technical discussions within our small, highly intelligent team, logically defending your assumptions and architectural choices. Work with our ISO processes and support continuous improvement of our quality landscape. A day as a Software Engineer You start your day syncing up with your tight-knit team consisting of electrical, software, and control engineers. You pick up a new feature request for the power converter firmware. Because you thrive on autonomy, you independently hunt down the necessary context, research the technical constraints, and map out a solution. You spend the morning writing clean, async Rust code. After lunch, you join a whiteboard session where your recent architectural choices for the cloud-data stream processing system are heavily challenged by your peers. You enjoy this interaction and you confidently explain the exact assumptions you made and how they logically lead to your decision, embracing the mutual learnings the discussion brings. You finish your day refining a pull request, ensuring the code quality is so high that it breezes through the mandatory code, safety, and security reviews with barely any comments. What do we expect from a Software Engineer? In order to succeed in the dynamic world of Lightyear; pro-activity, professionalism, communication and adaptability are crucial. We are looking for someone with an ambitious attitude who learns from the past but who is especially open to transforming new developments or ideas into the ‘tried and tested’ of the future! BSc or above in Software Science, Electrical Engineering, or related studies Experience with (deeply) embedded software Experience with automotive quality and safety standards (specifically ISO 26262) is highly desired. Experience with model based engineering is a plus. Experience with control of power converters is a plus Experience designing applications in a cloud-native environment and working with real-time stream processing systems is a plus Strong proficiency in Rust, specifically writing asynchronous (async) Rust for both embedded firmware and cloud applications. Exceptionally logical thinker who doesn't shy away from intellectual debate. They view rigorous challenging of their work as an opportunity to learn rather than a personal attack. Detail-oriented with a strong sense of craftsmanship and pride in delivering flawless code. What can you expect from Lightyear? In addition to a challenging role 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 Participation in a good pension scheme 40 vacation days per year (based on a 40 hour contract) Why join us? Be a part of a small and driven team at a technology start-up with a strong focus on sustainability; Engage in a collaborative work environment that encourages innovation, independent thinking and close cooperation; Contribute to cutting-edge solar technologies that aim to revolutionize vehicle charging systems; Opportunity to grow with the company as we accelerate and expand our impact in clean mobility. About Lightyear Lightyear Layer is at the forefront of sustainable mobility, offering innovative solutions that help businesses reduce CO₂ emissions and enhance operational efficiency. Our Vehicle Integrated Photovoltaics (VIPV) platform provides grid-independent, solar-powered solutions that maximize energy yield and efficiency, driving a greener future.

Core Responsibilities

Develop production-ready asynchronous Rust firmware for solar power converters and build real-time data-stream processing to monitor system performance. Follow ISO 26262-compliant quality and safety processes, take ownership of technical work, and collaborate with multidisciplinary teams on architecture and continuous improvement.

Requirements

A bachelor's degree or higher in Software Science, Electrical Engineering, or a related field and experience with deeply embedded software are expected. Strong asynchronous Rust skills are required; automotive safety standards experience is highly desired, while model-based engineering, power converter control, and cloud-native real-time stream processing experience are advantageous.

Benefits

• Pension Scheme
• 40 Vacation Days Per Year
