Who we are 

At Ona, we don't just strive for diversity, we thrive on it. For Ona, diversity has been a spring board for creativity, innovation, and growth. We are committed to giving equal opportunities to employees and applicants regardless of their race, religion, gender, sexual orientation, colour, nationality, age, marital status, or pregnancy status.

We're looking for developers who want to build foundational data systems that drive change. Our team has worked on projects that record the social infrastructure of entire countries, tally the winners of national elections, and reduce infant mortality. We build software that solves real problems and you will too.

  • You are committed to the projects you work on and need to see them through to completion. You understand that solving the user's problem is the end goal.

Lifelong learner 

  • You stay up to date with the latest trends and are excited to learn new languages, tools, and best practices.


  • You thrive in teams and projects that span time zones and cultures.
  • You're ready and excited to travel in order to support projects, no matter how dusty or remote.

  • Minimum 5 years programming in Python, JavaScript, or Java.
  • Experience programming with APIs and service based architectures.
  • Strong attention to detail and understanding of architectural dependencies.
  • Strong troubleshooting and problem solving skills.


  • Previous experience as a data engineer or in a similar role. 
  • Experience with PostgreSQL, SQLite, other relational, k/v, column-oriented, or log-based databases.
  • Experience with Ansible, Terraform, AWS, Alibaba Cloud, other IaaS and infrastructure as code systems.
