Principal Cloud Engineer

At Gigaton, we’re on a mission to cut gigatonnes of carbon emissions from the world’s biggest emitting industries (like cement, steel and glass), by building autonomous AI control and optimisation systems that learn and leverage the physics of manufacturing. Our products run heavy industrial plants more efficiently, more stably, and with lower emissions in real time - laying the foundation for the next industrial revolution.

We are a team of scientists, engineers, builders, and operators who love hard problems, have high standards, and want to make change happen in the physical world. We care about deep tech, but we care even more about whether it delivers cost and carbon impact in a live plant, with real people, under real constraints.

With Gigaton, you’ll solve really tough problems in places few people ever get close to, and build something that actually helps the planet. Are you up for the challenge?

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

Secure, repeatable deployments across enterprise cloud environments. Increasingly, Gigaton deploy cloud workloads across GCP, AWS, and Azure, so that we can deploy ML‑Ops and data solutions inside our customer’s perimeter. You will help to design, simplify, and improve our entire stack so that we can meet stringent cybersecurity guidelines, while remaining agile.

Set the technical bar, and lift up your team mates. As the most senior practitioner in the team, you will be a role model and mentor. You will help your team mates through review, pair programming, and architectural oversight, so that every engineer becomes better for working alongside you.

A clear architectural roadmap for cloud and Dev Ex
. Gigaton have ambitious goals, and we need to move quickly. You will be entrusted with the architectural decisions that help our entire engineering organisation ship  will lead through collaborative work and design documents, to build consensus and plan the work that unblocks and supports our engineers.

• 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.

• 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 to collaborate with others and are familiar with agile technical practices, including pair programming, mobbing 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.

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

• 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.

• 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…
