About the Role

Phykos is hiring our first dedicated software engineer. In this role, you will work independently and collaborate across the engineering team to support further development of our open ocean seaweed farming systems. You will work on all stages of prototype development from concept to field testing of both on-platform and backend software systems.

This is an early stage role with significant impact on the shape of our future systems, replete with opportunities to learn and grow your skills within and beyond software engineering. You will also join a startup tackling the climate challenge head on with a mission to sequester one billion tonnes of CO2 annually in the deep ocean!

Why you should join Phykos

Phykos, PBC is an early-stage ocean carbon dioxide removal company. We’re building a distributed, autonomous system to grow seaweed on the open ocean and sink the resulting biomass below 1500 meters, thereby storing carbon for 1,000 years or more. The oceans have absorbed more than 93% of the excess heat from anthropogenic climate change, and increasing acidity from ocean carbon is a threat to many marine species. Our carbon removal system cleans, cools, and deacidifies the global oceans while drawing CO2 out of the atmosphere to prevent catastrophic climate change.

You can read more about our approach in this recent FastCo article. You can learn more about ocean CDR approaches, including seaweed cultivation, at OceanCDR.

At Phykos, we are committed to building a diverse team in an inclusive environment that fosters collaboration and growth. All qualified applicants are encouraged to apply.
