- Capability and curiosity suitable for work in an early-stage environment.
- Interest in critical minerals technology and the company's work.
- Applicants may come from backgrounds such as hydrometallurgical engineering, pilot operations, business generalism, or other relevant disciplines.
- Applicants must submit a resume and a short note describing what draws them to Still Bright.
- Contribute within one or more of the team's areas spanning electrochemistry, process engineering, operations, and business.
- Work in a small, high-ownership team developing technology in the critical minerals space.
Still Bright uses a hydrometallurgical RACER process to extract copper from sulfide ore at ambient temperature, employing a vanadium-based leach that dissolves copper. The copper-rich solution is regenerated with electricity to reuse the vanadium medium, enabling electrometallurgy and allowing up to about 99% copper recovery with renewable-powered operations. The system is modular and cheaper to scale (70–90% lower capital cost) and can process high-grade ore, tailings, and other difficult materials at mines of various sizes. The company aims to scale from a 2 t/year pilot to a 500 t/year demonstration by 2028 and ultimately deploy 10,000 t/year commercial units to establish a domestic copper supply chain.

Simplify's Take
What believers are saying
- It avoids smelting, cutting toxic sulfur emissions and enabling renewable-powered operation.[1][2]
- It can process waste tailings and low-grade ores previously uneconomical to refine.[1][6]
- The company plans a 500-ton annual demonstration unit, then 10,000-ton commercial systems.[1]
What critics are saying
- Pilot-scale performance remains unproven outside laboratory and small pilot conditions.[1][2]
- Copper producers can switch to established flotation, smelting, or electrowinning pathways.[5][10]
- Vanadium supply and pricing can pressure operating economics and reagent availability.[1][2]
What makes Still Bright unique
- RACER extracts nearly all copper from ore at ambient temperature and pressure.[1][2]
- The process uses a vanadium-based solution regenerated by electricity for reuse.[1][2]
- Still Bright targets modular copper extraction with far lower capital costs than smelting.[1][2]
