Senior Product Engineer

UNDO is one of the world’s leading carbon removal companies, and one of the four global winners of the $100M XPRIZE, further giving recognition and credibility to both enhanced rock weathering (ERW) and UNDO as a world leader in this field.

This is a rare opportunity to build software that is genuinely consequential in a real-world sense. The platform you’ll help design and build will underpin the global scaling of enhanced rock weathering, removing carbon from the atmosphere at the scale the planet actually needs.

The platform infrastructure to match that ambition is still being built. You’d be joining at the moment that matters.

As part of UNDO’s growth, this role is joining at a pivotal time as we design and develop an industry-leading end-to-end ERW platform offering that can support rapid growth and scientific innovation.

You’ll be joining a lean team of senior full-stack engineers, built on strong judgement: people who know when to move fast and pragmatically, when to invest in lasting infrastructure, and how to pick the right tool from an ever-expanding technology landscape. The work spans a genuinely broad surface area: scientific integrity constraints, complex data pipelines, operational workflows, and the user-facing interfaces that tie it all together.

Every job ad right now mentions AI and we’re no different, but we want to be honest about what we mean by it. We’re looking for someone who understands that AI tooling is genuinely transforming the SDLC, and can keep pace with what’s emerging, has strong views on what’s actually useful and will help accelerate UNDO’s adoption in ways that genuinely stick.

But we also want someone who is clear-eyed about where AI delivers and where it doesn’t, and who won’t let hype drive architectural decisions.

• Own feature development end-to-end - from working with product, science and partners to understand the problem, through design, build and deployment, to maintaining features in production
• Design and maintain our technical infrastructure - including CI/CD pipelines, infrastructure as code and cloud infrastructure to ensure reliable and repeatable releases
• Build software that supports scientific rigour, data integrity and transparency
  , aligned with UNDO’s mission in climate and sustainability.
• Advocate for better engineering - participate in architectural decisions, contribute to our engineering standards, and help shape how the team works, advocating for pragmatic, scalable solutions while remaining open to alternative approaches

• Product mindset. We strongly believe that the best engineers care about more than just the code adhering to its spec. We want you to be interested in why you’re building what you’re building.
• Good architectural instincts. You know when to invest in generalized, reusable solutions, and when a well-scoped, bespoke approach is the smarter choice.
• Technological curiosity. You’re genuinely excited by new technology such as new tech stacks and AI tooling, with flexibility across multiple stacks, and a commitment to choosing the right tool for the job.
• Excited by the idea of working in a small agile team at a startup
  , comfortable with a fast pace, working with ambiguity and pivoting in direction as needed
• Opinionated but collaborative. You hold strong views and express them clearly, but remain curious and genuinely open to being persuaded
• Strong understanding of the value of testing. You care about quality and understand that good tests are about more than a coverage number. You understand the value that good testing unlocks, especially with increased adoption of AI.

• Experience building data-intensive applications with complex business rules, in variants and data integrity requirements.
• Hands-on experience using AI in daily engineering work, and active advocacy for AI adoption within your team, with a considered view on how it’s reshaping the SDLC, what it unlocks and how to leverage its capabilities.
• Ownership of the entire feature lifecycle - from discussions with product and stakeholders, through development, deployment, and maintenance in…
