Requirements

  • Strong experience with Python.
  • Experience designing and implementing services in the cloud (AWS).
  • Experience deploying containerized applications with Docker and/or Kubernetes.
  • Experience with databases and ETL systems (PostgreSQL).
  • A test-driven development mindset, with solid CI/CD and documentation practices.

Desired qualifications

  • Python web frameworks such as Django or FastAPI.
  • Python ETL tooling such as pandas, SQLAlchemy, or dbt.
  • Deployment tooling such as Argo within a Kubernetes environment.
  • Comfort working in a Linux environment.
  • Entrepreneurial energy and determination.
  • Interest in remote sensing systems and space. 

Eligibility 

All applicants must be legally entitled to work in Canada and must meet the requirements of the Canadian Controlled Goods Program (CGP).

Benefits

This is a rare opportunity to work on urgent problems. You'll join a small but high-impact team and help scale a company doing meaningful work for the planet.

  • Competitive salary and stock options for all full-time employees
  • Health and dental benefits
  • Paid time off and floating statutory holidays
  • Flexible work environment
