About Us:
We are building a world-class foundational science team, founded by former Tesla leadership. We’re a well-funded seed-stage sodium-ion battery company focused on truly redefining the future of energy storage and we are very excited about it.
The Role
As our Chemical Technician (Materials Scale-up and Optimization), you will work closely with the Materials R&D team. You will support active material synthesis trials with batch sizes typically ranging from benchtop scale (50-200 g) to pilot trials in the 1-5 kg range.
What You’ll Do: The following responsibilities include, but are not limited to:
· Hands-on support of synthesis trials at benchtop (50-200 g) and pilot scale (1-5 kg).
· Making solutions of metal salt solutions as precursors for precipitation reactions.
· Pre-treatment of metal salt solutions to eliminate impurities.
· Operation of precipitation reactor using process control software.
· Filtration, washing, drying of reaction products.
· Powder processing and solid-state synthesis steps such as ball milling, dry blending etc.
· Operation of tube furnaces and/or controlled atmosphere muffle furnaces for calcination reactions.
Qualifications We’re Seeking
High school diploma or equivalent required; Associate degree or technical certification in manufacturing, materials science, chemistry, or engineering technology preferred.
Working knowledge of chemical synthesis, preferably in production of battery active or similarly advanced solid materials.
Ability to follow detailed SOPs and DoE instructions precisely.
Comfort working with fine powders, corrosive acids and bases, and chemical handling procedures.
Experience with working in gloveboxes.
Ability to wear required PPE (respirators, gloves, safety glasses) for extended periods.
Ability to lift heavy items (up to 40 lb.)
Strong attention to detail and commitment to documentation accuracy.
Good communication and observation skills
Bonus / Preferred
Direct experience working with precipitation reactors at 5 – 10 L scale or higher, and/or with calcination processes
Direct experience with synthesis process optimization and scale-up for cathode active materials used in Li-ion and/or Na-ion batteries.
Direct experience with Li-ion and/or Na-ion battery cells and their components.
Direct work experience with automated process controls and HMI systems.
Work Environment:
Innovative / flexible / yet fast-paced development environment
Very close collaboration with technical team and stakeholders across the company
Small, growing, international team from 7+ countries
Office snacks include healthy options, chips, drinks
Onsite work schedule currently
Why join:
Ground-floor opportunity to shape both the science and the culture of a well-funded seed-stage company
Direct access to founders; no bureaucratic barriers to pursuing bold ideas
Work on a problem that matters - sodium-ion is one of the most consequential battery chemistries of the next decade
