Rayleigh Solar Tech

Key Responsibilities:

• Electrical & system architecture: Own design of module interconnects, power distribution, junction placement, protection schemes, and DC/AC layouts for flexible PV products - crafted to minimize installation effort and reduce balance-of-system hardware.
• System-level modeling & interrogation: Evaluate how electrical design choices (stringing, MPPT mapping, conductor sizing, tilt, orientation) affect yield, cost, and deployability. Build models and trade studies to guide architecture decisions.
• Grounded innovation: Apply an understanding of c-Si deployment practices and EBOS (electrical balance-of-system) realities, while still pushing the boundaries of what's possible in flexible PV form-factors and radical product formats.
• Prototyping & validation: Build and test prototypes, collect data to validate energy/performance assumptions, and iterate quickly.
• Manufacturing integration: Collaborate closely with mechanical/process teams to translate electrical designs into scalable, manufacturable product and fieldable systems.

What You Bring

• BS/MS in Electrical Engineering or related discipline.
• Experience with PV systems, including c-Si deployment models, string design, inverters/charge controllers, and BOS hardware.
• Ability to model array energy output using tilt/orientation vs. architecture (Python, Matlab, PVSyst, etc.).
• Strong system-level thinking, able to question assumptions and consider real-world installer, wiring, and EBOS realities.
• Creativity to merge those ground truths with radical innovation, designing something truly new without losing practicality.
• Hands-on mindset; comfortable prototyping, testing, and iterating in a fast-moving start-up.Top of FormBottom of Form

Core Competencies:

• Practical wizard: Someone who starts with "what if" and finishes with "it works"
• Hustle: Ability to work fast and smart; time management is key for a start-up
• Adaptable: Start-ups are dynamic; our people must be, too
• Curiosity: Excited to take their prior experiences and apply it to a solar product
• Execution: Commitment to delivering results and leading by example. This will include bringing clarity to complex tasks through methodical processes, mentorship, and documentation
• Effective: Proven ability to work effectively across cross-functional teams, including product design, technologist, and operations

Here at Rayleigh, we're commercializing the next generation of solar technology: flexible perovskite solar panels. Our company is united by our commitment to change the planet for the better. We push the boundaries of what's possible, our passion for deep tech to solve hard engineering problems, our insatiable curiosity that forces us to ask questions, and our relentless drive for excellence in everything we touch.

Why Join Us

You'll join a small, fast-moving team building hardware that matters. This is your chance to take ownership of design work that gets built, tested, and deployed in the real world-and to shape not just how our solar system looks and works, but how it scales. If you're ready to learn fast, think creatively, and contribute to something with real impact, we want to meet you.

Diversity and Inclusion

At Rayleigh, we know that diversity makes a strong team. We encourage all qualified applicants to apply for this position, and we will never discriminate against race, ethnicity, gender identity, gender expression, sexual orientation, disability, religion, marital status or family status. Instead, we work to celebrate the things that make us unique and create an inclusive environment for all employees.

Don't meet all the requirements outlined above but still find yourself excited about this position and Rayleigh's mission? If you believe that you have the skills and experience to excel in this role, we would love to see your application!
