Ask HN: Who is hiring? (March 2026)

Electrical / Power Systems Engineer - Build a battery-integrated sauna heater

Paid contract role, $80 - 150/hr, 15–25 hr initial scope

This is a multi-kW DC system problem (battery pack, resistive heater, contactor, safety logic). The constraint is reaching sauna temps without relying on a 240V wall connection.

We currently generate ~$5k MRR renting saunas in the SF Bay (sfsaunarental.com). We've validated pain-point and demand.

If there’s mutual interest and the prototype goes well, this could extend into deeper collaboration or a more dedicated role.

Think of github but for hardware design. (PCB and Schematics design). Our mission is to bring the same modern workflows that revolutionized software: version control, automation, and collaboration to the hardware world. We are also introducing AI to hardware design!

We work on:

• Parsing complex ECAD formats (Cadence, Altium, etc.).

• Schematic/PCB diffs (not just text).

• Hardware CI pipelines (BOM, DRC, PLM integrations).

• AI-assisted design reviews.

• Scaling a Git-based platform for non-software engineers.

Stack: Go, Python, Rust, Vue/TypeScript, Postgres, AWS, Docker, Terraform (Gitea-based core)

Open roles:

• Principal Engineer (Parsing)

• Senior Infra Engineer (Infra)

Looking for engineers who like deep systems problems and high ownership.
