Senior Backend Engineer

About Us

Isometric is a carbon removal registry. We issue the world’s most scientifically rigorous carbon credits to help Fortune 100 companies tackle climate change and prevent greenwashing.

We're growing quickly, but we’re intentional about hiring people who contribute to our unique culture. Our team is smart, meticulous and courageous—but warm, kind and supportive too.

We’re led by Eamon Jubbawy, an experienced CEO who previously co-founded Onfido, the world’s leading AI-powered identity verification platform. He scaled the company to $100m+ in revenue—verifying over half a billion identities and catching 23 million fraudsters—before selling the company for $650m. Eamon started Isometric in 2022 to bring the same level of rigorous fraud prevention, confidence and trust to the carbon removal industry.

The wider Isometric team includes scientists from Oxford, Cambridge, Harvard, MIT, Yale and Stanford— and technologists from companies like Amazon, Shopify, Meta, Google, Wise and Palantir.

We’re backed by world-class investors with real-world experience in climate change and company building: Lowercarbon Capital and Plural.

Join us if you're ready to take on a career-defining role. Working here will be unlike any job you've had before!

Outcomes you’ll be responsible for

• Let companies purchasing carbon removal credits understand and inspect down to a source how, when and if that carbon was truly removed, converted and stored permanently by building a flexible software and hardware platform.

• Define novel measurement, reporting and verification mechanisms that let the carbon removal industry scale.

• Build an early engineering team culture that values scientific rigour, pragmatism, learning and teamwork through mentoring your teammates.

Tasks you might do

• Correctly process structured and unstructured data in batch or real-time fashion, applying mathematical and machine learning models to it, all the way to making it available via APIs to our data visualisation layer.

• Design scalable systems that let us move fast today, but are flexible enough to evolve over time – as we learn more about what the world needs from us.

• Mentor your peers and support your team in achieving the team goals.

Aptitudes you’ll display

• Eagerness to learn new things and ask all the questions. We are science-driven and expect everyone to get stuck into the climate world.

• Drive to urgently solve big challenges that have no obvious answers today. We’re doing novel things that no one person knows the answer to today.

• Bringing good energy and humility into how you show up. It’s a tough problem but we can’t give up.

How we build

Our engineers are diverse and product-minded with background experience in highly varied environments, from writing the first line of code at Day 0 startups, to building high scale systems at companies like Meta, Deliveroo or Shopify.

Our backend is built with strongly typed Python using Strawberry, communicating via an auto-generated GraphQL client with our Next.js, React and Typescript UIs (with Tailwind for CSS), and backed by a Postgres DB. Our production services run in containers on Google Cloud Platform, managed by Terraform. We use Sentry and Datadog for observability. Our monorepo codebase is hosted in Github and we use Graphite for stacking PRs.

We collaborate in Slack, Figma, Notion, Airtable, Zoom and Google Workspace. We believe in high quality code reviews and investing in automation or tools that maximize developer productivity.

We’re happy to work with humans with experience in all, any or none of these tools and technologies.

Equal employment opportunity commitment

We’re growing quickly, but we’re intentional about hiring people who contribute to our unique culture.
