Senior Software Engineer

Our Mission At Carbon Re, we’re on a mission to cut gigatonnes of carbon emissions from the world’s biggest emitting industries, like cement, steel, and glass, by applying cutting-edge AI where it matters most. We’re a small and growing team of scientists, engineers, and strategic thinkers who care deeply about impact and believe in getting there with good humour and urgency. Our SaaS products help heavy industry optimise operations in real time, cutting costs and carbon today while building the foundation for the next industrial revolution.

We're looking for a Senior Software Engineer to join our platform team and help us push the boundaries of what AI can do for the planet.

We don't draw a specific line between engineering and research teams. We operate as one cohesive unit, sharing tech stack, knowledge, and objectives. Our focus spans from fundamental ML research to commercial-grade software development, offering diverse learning and impact opportunities.

Why this role exists

Carbon Re is scaling deployments from a handful of sites to dozens of plants per year. Large industrial operators have the biggest decarbonisation potential, but they also have strict security and networking constraints. Until recently, most of our systems lived in our own cloud. Now, we're building the capability to run our workloads effectively in our customers' own environments.

We need a Software Engineer with solid cloud architecture experience to help us smash this out of the park. You'll be a senior individual contributor partnering closely with product, ML, and solutions teams.

Your main responsibilities

• Own key platform components across AWS and GCP, shaping architecture for scalable, secure systems.

• Deploy and operate our workloads inside customer-owned cloud accounts, working directly with their IT and infrastructure teams to navigate requirements and constraints.

• Assist more junior team members with their development, helping them learn core software engineering skills and best practices.

• Propose and drive improvements to existing systems and pipelines.

What a great fit looks like

• You have deep experience with AWS or GCP (bonus points for both!). You have a solid understanding of cloud networking.

• You're fluent in Python and Terraform.

• You have designed or owned CI/CD pipelines for frequent, safe releases.

• You love collaborating with others and are familiar with agile technical practices, including pair programming, mob programming, and TDD. You balance good engineering practices with pragmatism: you know when "good enough now" beats "perfect later".

• We're a startup! You are comfortable with ambiguity and enjoy owning a problem from discovery to delivery.

Bonus points:

• You've worked in industrial, IoT, or similarly complex environments

The ways we like to work

• We are a collaborative team. We regularly and eagerly pair and work through problems together. We love bouncing ideas off each other!

• We have regular retrospectives to keep getting better as a team.

• No-blame culture: we support each other when things go wrong and always run post-mortems so we never make the same mistake twice. You'll get a badge for causing your first production incident 🎉

• We ship fast. We are proud of our CI/CD pipeline and quality gates, and we review our teammates' work quickly. Our small team regularly deploys over a dozen times a day. Yes, we ship on Fridays.

• We are hooked on observability: we strive to get visibility over all parts of our system to make incident response as painless as possible and to know what needs to improve.

In return for your hard work, we’ll give you

📈 Equity in the company: When we win, you win. You’ll get share options, so you’re part of our journey from the inside.

🏭 Concrete Honesty: Be honest. As concrete forms the foundation of our world, genuine honesty and transparency are the bedrock of our culture.

😄 Cement it with Kindness & Fun: Have fun, be kind. We're here to extend Earth's life, but ours is still limited. We want to enjoy the ride. To see these in full, go to Carbon Re’s Operating Principles Notion page.
