CTO (Chief Technical Officer) Candidate/ Senior Software Engineer

Our Company

sustainacraft, Inc. focuses on nature-based solutions (NbS) for climate change and aims to maximize their effect through a more accurate carbon accounting system. While it is important to expand projects in forest conservation, sustainable forest management, and agriculture, it is equally imperative to ensure the transparency of such projects and the sound circulation of funds while increasing credibility.

We are currently working with environmental NGOs, financial institutions, and international development agencies in Southeast Asia, Latin America, and Europe to create a healthy financial cycle for nature conservation through two approaches: monitoring natural resources using satellite imagery and assessing appropriate reference levels using causal inference techniques.

Working Environment

Our Working Environment

We encourage asynchronous communication through services such as Notion, Slack, and Loom, making it possible for people to work regardless of their location.
