Development Enablement Software Engineer in London

About the role
We are 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 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.

Your main responsibilities:

• Talk to colleagues about their work, the processes they follow, and the roadblocks they face.
• Propose, design, build and document robust software systems to meet those needs.
• Assist more junior team members with their learning and explain how things work.
• Deliver pragmatic solutions that balance short-term delivery with long-term maintainability.

What a great fit looks like:

• You are fluent in Python and Terraform.
• You are excited about building internal tooling and CI/CD.
• You have worked in a cloud environment; bonus points for Google Cloud expertise.
• You love to collaborate with others and are familiar with agile technical practices, including pair programming, mobbing and TDD.
• You are comfortable with ambiguity and enjoy owning a problem from discovery to delivery.

You will excel if:

• You are seeking a role in climate tech, or tech for good.
• You have a genuine interest in machine learning and the physical sciences.
• You have opinions about how to build robust model deployment platforms.
• You are not expected to check every box, and we would love to hear from you even if your experience isn’t an exact match.

We are building a team that reflects the world we want to change. Our people come from all walks of life - different countries, cultures and experiences - and we think that’s one of our biggest strengths. We are committed to creating a workplace where everyone feels safe, respected and celebrated. No matter your background, if you are excited by what we do, we want to hear from you.

In return for your hard work, we offer:

• A competitive salary £75-90k
• Equity in the company. When we win, you win. You will get share options, so you are part of our journey from the inside.
• Flexible working. We trust you to know how and when you work best and to work that out with your team.
• 30 days of holiday (plus bank holidays). Rest is productive. Take the time you need to recharge.
• A generous pension scheme. We are planning for the future in more ways than one.

The interview process:

• We run a 4-stage process for engineers after the initial short screening call to confirm alignment on role expectations, experience, and next steps.
• Pair programming: you will meet with one of our other engineers to work on a toy problem together. You can use Google or LLMs, or you can ask your pair for help. We want to know what you are like to work with, how you approach solving problems in an unfamiliar space, and how you communicate about code.
• Whiteboard session: you will meet with two of our engineers. We will ask you to draw a diagram of a system you are familiar with and walk us through its major architectural components. We will ask questions about the decisions you made, and the things you like and dislike. We want to know how well you understand the technologies you use, and how you communicate about complex technical matters.
• Operating principles: You will meet with some people from other parts of the business. We will ask you questions to understand how you would work in a culture governed by our operating principles.
• Meet the CEO: before we make an offer, we would like to schedule a 15-minute chat with Josh, our CEO.

We believe hiring is a two-way process. Just as we will reference-check candidates before making a final offer, we encourage you to reference-check us by chatting with team members you haven’t yet met. Ask anything. We will answer with Concrete Honesty.

Once interviews are done, we will move quickly to a decision, and we are always happy to give feedback at any stage.

Our operating principles:

• Concrete Honesty: Say it how it is. Our honesty is strong, foundational, and built to last.
• Forever Optimising: We are in the business of constantly tweaking, testing and improving.
• Increase Torque: We move with urgency because the climate crisis won’t wait.
• Maintain Reliability: We build trust by showing up, following through, and having each other’s backs.
• Cement It with Fun & Kindness: We are here to extend Earth’s life, but ours is still limited. Let’s enjoy it and be good to each other while we do.
