Planetary’s vision is to restore the climate and heal the ocean for generations to come. We do this by enhancing the ocean’s natural ability to fight climate change through carbon dioxide removal and storage. Our team combines expertise in ocean science, metallurgy and geochemistry to safely and effectively scale up ocean-based CO2 management solutions. Working collaboratively with all of our stakeholders, we develop a cost effective and sustainable set of tools aimed at protecting and restoring our oceans and climate, ultimately doing carbon dioxide removal and storage at gigatonne scale.

We are leaders, scientists, and engineers working together to collectively embody our values: respect, curiosity & creativity, accept responsibility, and win for all.

Planetary is seeking a software developer who has a sincere desire to apply their talent and experiences to tackling climate change within a self-managing and mission-driven organization. Day to day, this person will actively design and develop our Ocean Carbon Platform (OCP) with a cross disciplinary team of scientists, engineers, and operational / project team stakeholders. The OCP is a modern greenfield cloud-based software product that will connect many of the key pieces that are at the heart of the end-to-end ocean carbon removals crediting system at Planetary.

This role not only delivers value by taking cloud based software solutions to market - but also plays a key role to ensure such solutions are robust, are of high quality, and reliably enable the verification of carbon credits with 3rd party verifiers at scale. Welcoming talented and experienced developers who care about the planet and who love working with smart people with diverse backgrounds who thrive in product focused mission driven environments.

  • Incorporating deep technical proficiency and expertise with emerging domain expertise and knowledge
  • Adapting communication to the intended audience by being, engaged and generative in all interactions

Design, develop, and deploy fit-for-purpose full-stack cloud-based software platform by:

  • Ensuring usability, maintainability, testability, security, and performance of such a system
  • Applying sound engineering and architectural practices and principles
  • Evaluating and suggesting alternative technology solutions to support valuable outcomes
  • Defining technical test flows and ensuring appropriate test coverage via unit and integration testing
  • Continuously maintaining code base by qualifying and resolving software flaws
  • Reading, reviewing, understanding, and making improvements to the existing code base
