Job Description

Paid contract role to build a battery-integrated sauna heater. Multi-kW DC system design involving battery pack integration, resistive heater, contactor, and safety logic. The constraint is reaching sauna temperatures without relying on a 240V wall connection. Initial scope is 15–25 hours; compensation is $80–$150/hr. If the prototype goes well, there may be deeper collaboration or a more dedicated role. To apply, email zach@sf-sauna.com with a short description of the EE project you're most proud of building from scratch and a link (GitHub, project photos, writeup, resume, etc).
