Solar IoT Device Consultation and Supplier Sourcing

About us

We're a small climate technology company building solar-powered IoT monitoring devices that run off-grid in the field. Our design uses off-the-shelf components, and we write the device software in-house. We're looking for an experienced engineer to review our design and advise us, not to build it from scratch.

We're also coming to Shenzhen to source components and have contacts there, the ideal candidate would also be able to help in finding the right suppliers.

What you'll do

- Review our hardware design and advise on components, connections and protocols
- Advise on low-power and solar/battery design, and on outdoor enclosures and connectors
- Review parts of our device code where your experience helps
- Recommend reliable suppliers in Shenzhen, and potentially join us for a few days during our sourcing trip
- Advise on samples, minimum order quantities, quality checks and export

Must have

- 5+ years in embedded systems or IoT, with devices you've shipped that run in the field
- Embedded Linux on single-board computers
- Industrial sensor interfaces and protocols (e.g. RS485/Modbus), Bluetooth Low Energy, cellular modems
- Low-power and solar/battery design
- Based in China, ideally in or near Shenzhen, with working contacts in the Shenzhen electronics supply chain
- Good written and spoken English

Nice to have

- Microcontroller firmware (e.g. ESP32)
- Outdoor, off-grid or agricultural deployments
- Experience with IP-rated enclosures and waterproof connectors
