Founding Software Engineer

Location: Hybrid (London)

Compensation: Competitive salary + meaningful equity package

We’re building software to support one of the largest infrastructure and industrial transitions of our time.

Better decisions around energy, resources, and critical systems increasingly depend on high-quality software, data, and modelling capabilities. Our mission is to create modern tools that help organisations move faster, plan more effectively, and accelerate positive real-world outcomes.

We believe technical infrastructure matters. Better software enables better decisions — and better decisions compound.

This is an opportunity to join an early-stage team with strong momentum, real users, and the chance to shape both the product and engineering culture from the beginning.


The Role:

We’re looking for software engineers who enjoy solving difficult technical problems and building products that have measurable impact.

You’ll work across the stack to design, build, and ship software used to support complex decision-making environments. The role is broad and suited to engineers who like ownership, move quickly, and enjoy working close to both users and product.

This is an environment that values execution, technical depth, and practical thinking over process for process’s sake.

What You’ll Be Working On:

Projects may include:

  • Building scalable backend systems and developer platforms
  • Designing APIs and services for large-scale data workflows
  • Developing tools to process and analyse complex operational datasets
  • Creating intuitive product experiences for technical users
  • Improving performance and reliability across applications
  • Designing data architectures that support decision-making at scale
  • Building internal automation and AI-enabled workflows
  • Experimenting with optimisation techniques and modern compute approaches
  • Turning technical ideas into production products quickly

What We’re Looking For:

You may come from software engineering, infrastructure, data platforms, scientific computing, machine learning, or another technical field.

We care more about capability, curiosity, and ownership than direct industry experience.

You’ll likely thrive if you:

  • Enjoy building and shipping production software
  • Learn technical concepts quickly
  • Take ownership from problem definition to delivery
  • Are comfortable navigating ambiguity
  • Balance speed with thoughtful engineering decisions
  • Care about creating products that deliver real value

Helpful experience includes:

  • Python, TypeScript, Rust, or similar languages
  • Backend services and API design
  • Cloud infrastructure and containerisation
  • Data engineering and large datasets
  • Modern frontend technologies
  • AI-assisted development workflows

Why Join:

  • Work on software connected to real-world outcomes
  • Help modernise critical industries through technology
  • Join early and influence product and technical direction
  • Meaningful ownership and autonomy
  • Competitive salary and equity
  • Hybrid working with a small, highly capable team


This role suits engineers who want to build ambitious products, move quickly, and apply software to problems that matter.
