About the job

Want a tedious, repetitive technician job? Don’t apply here. Looking for something interesting, with growth potential and skill development. Check out this position.

Ionobell is a well-funded early-stage startup partnering with over a dozen major automotive and electronics companies to develop the next generation of high-energy-density batteries.

We are looking for experienced lab technicians who can consistently build battery cells without supervision while learning new skills and techniques. Play an active part in the development as you help us build prototype cells for our clients in our new lab in San Jose

What we are looking for:

  • Practical experience. Could you find the mixer if we let you loose in the lab? Coater? Fume hood? Given instructions and materials, could you make a slurry without needing help?
  • Basic equipment knowledge. Have you ever used mills, fume hoods, mixers, gloveboxes, and coaters before?
  • Basic Chemicals. Have you worked with battery chemicals before? Carbon, silicon, binders, and conductive additives? Could you put them together without burning down the lab?
  • Work without bureaucracy. Really. You will be given objectives and expected to get things done. If you are looking for daily meetings, constant report writing, and a requirement to write endless status update emails. Apply elsewhere.
  • Be responsible for results, not effort. We focus on results, not effort. So management check-ins, status reports, and planning meetings are rare. Get stuff done and go home.
  • Be safe above all else. Try not to melt anything substantial, but get the lab work done.
  • Diversity-minded.
  • And various things we have not thought about yet, but I am sure we will once we meet you.

Your Objective:

  • Is to assist the development team in generating prototype batteries for our clients. Following directions, careful work, and documentation are essential. The ability to adapt and learn is also beneficial.


  • At least 1-year experience working in a lab setting
  • No specific education is required

Growth Opportunity:

  • As we continue to grow, there will be significant opportunities to grow toward management and research.


  • Competitive salary, options, healthcare, dental, and vision provided.

About Us:

Ionobell is a well-funded battery startup with over a dozen current automotive, electronics, and battery production partners. We are a licensing-only company. Since we only license and don’t have production, just research. Our R&D team is the core of the company’s value. We have a brand new battery lab in San Jose. Our culture is objective-driven, so you will be given resources, flexibility, and trust if you hit your objectives. Our technology enables smaller, lighter, longer-lasting electronic devices, and we are in a position to drive the cost of electric vehicles down dramatically. Our founding team has invested, founded, and exited multiple companies with six engineering degrees from Stanford and similar institutions. Join today and be part of the early development team.
