🔋 About Us

Hi there!

We know you've seen many job descriptions. This one might look like the others, but what we’re building, and the role you could play in it, is something we are very excited about.

We are Bihar Batteries, a new-generation battery startup based in San Sebastian. We are building sodium-ion storage systems, a critical technology that gives people, businesses, and communities control over their energy.

Unlike lithium-ion, our sodium-ion technology is made with locally abundant raw materials like salt. This means no critical supply chains, and a hopeful path towards energy independence in Europe.

This technology is at the heart of our product: a modular battery system that can power everything from off-grid mountain refuges to industrial companies and regions.

Here are some highlights of what we’ve achieved so far:

• We have developed a working sodium battery prototype and proprietary sodium cells.
• We have partnered with leading industrial companies and research centers to scale up, such as CIC energiGUNE and Battera.
• We are backed by early stage private investors, and have received two public grants to support our operations.

We believe batteries should not only be reliable, but also well-designed, easy to use, and attractive. This is why we are building a team that can turn these pieces into a product that people will be proud to use.

🙋 What We’re Looking For

We are looking for a Product Engineer to develop our battery system towards commercialization. We want you to be part of the entire design process, to interact with the partners who will manufacture it, and to learn from the clients that will use it.

As one of our first employees, we are looking for a curious and proactive ‘builder’ that is motivated with the challenge of joining an early stage company like Bihar.

We want you to feel that Bihar’s product is your product, and to be part of the company’s growth from a small group of individuals to an organization with international ambition.

🎯 What we Need

• Degree on industrial design, mechanical engineer or similar + sensibility for good design.
• A “builder” mindset: you like sketching, 3D modeling, prototyping, testing, and iterating.
• Strong CAD skills (Rhino, SolidWorks, Fusion 360, or similar).
• Knowledge of manufacturing processes (sheet metal, plastics, assembly) and certification.
• Ability to work with electrical and electronic components.
• Enjoying working in a startup: hands-on, proactive, flexible.
• Ability to work fluently in Spanish and English.
• Based in San Sebastian or willingness to spend significant time in the city (hybrid position).

🛠️ What you will be Doing

• Designing our battery system, including internal architecture and enclosures.
• 3D modeling, prototyping and testing the product.
• Challenging existing products in the market to create exciting new product features.
• Interacting with clients to inform the product development and ensure good user experience.
• Managing relationship with suppliers and product manufacturers.
• Assisting with product management and certification.
• Hiring and mentoring new teammates as we grow.
• Collaborating with partners to ensure products are functional, robust, and visually compelling.

🎁 What We Offer

• 🌍 Hybrid work flexibility, with the chance to combine remote focus time and in-person prototyping in our San Sebastian workspace.
• 💶 A competitive salary adapted to your experience, plus stock options.
• 💻 Brand new equipment both to design as well as to prototype (you choose).
• 🖍️ A career plan tailored to your experience and ambition.
• 📚 Training & education budget (courses, books, travel to events).
• 💰 Referral bonus for bringing in great people to the team.
• ✈️ An annual company offsite with the team to enjoy, talk and discuss company strategy.

🌍 Why Join Us?

Purpose

• Work on cutting-edge sodium-ion battery technology at a time when the world needs sustainable alternatives to lithium. Shape products that will power communities, companies, and outdoor environments across Europe.

Ownership

• As one of our first hires, your work will determine our product, culture, and company direction. Enjoy early employee benefits like stock options.

Team

• Build together with a team that has worked with international industry leaders like BYD, Cegasa, Norman Foster, or the MIT. Learn from leading European research and manufacturing partners.

Location

• Live and work in San Sebastian, one of Europe’s most beautiful and innovative cities. Beaches, surfing, and hiking at your doorstep. World-class gastronomy, cultural events, and a thriving innovation ecosystem in the Basque Country, surrounded by research and industry.

You will hear back from us soon with the following step of the process, and hopefully with an interview to get to know you better!

We welcome you to apply even if you don’t meet 100% of the criteria. At Bihar, we believe skills can be learned, and we strongly value people willing to grow inside the company.

We can’t wait to hear from you :)
