SOFTWARE DEVELOPMENT

Rainforest Connection is a San Francisco-based nonprofit building open-source solutions to illegal logging and poaching. Our flagship project is the world’s first real-time forest monitoring system, built from recycled Android smartphones.

We have a number of pilot deployments that will begin shortly. We’re looking to build an engineering team to join us and bring our platform to the next level throughout the stack.

Let us know what you can do and your requirements. We ourselves have been working on this project for 1.5 years without being paid, so we’re not afraid to ask others to dive in. If we’re successful, money is unlikely to be a problem. Our basic philosophy is that technology and innovation should be used to solve real world problems, rather than creating “shiny objects” or harnessing the best minds in the world to say ... democratize cab service across town.

We appreciate fast learners with a sense of hum

# A mill with less than 5% UMD loss from 2005-2012 is low risk, 5-28% is medium risk, and over 28% is high risk.
# One within concessions and one within entire radius
# Use the area of the entire radius or concession as the denominator (effectively assume 100% forested)
