Compensation: £70k–£120k salary (based on years of experience) + equity, based in London, UK.
We are hiring a Software Engineer to join Squid as one of our first engineers.
You'll work closely with the founders and early engineering team to build production software for grid operators. This is a broad engineering role spanning backend systems, frontend products, data-intensive applications, cloud infrastructure and applied AI.
You'll help turn complex engineering workflows into reliable, intuitive software used by planners, operators and engineers working on critical infrastructure.
This is a high-ownership role based in our central London office. You'll have the opportunity to shape the product, technical architecture and engineering culture from an early stage.
What you'll do
- Build and ship production software across backend services, frontend applications and cloud infrastructure.
- Design APIs, data models and product interfaces for complex, data-heavy workflows.
- Develop tools for loading, validating, comparing, visualising and explaining large technical datasets.
- Build reliable systems for versioning, collaboration, approvals and auditability.
- Integrate AI models and agents into practical, human-in-the-loop product workflows.
- Create benchmarks and evaluation systems for testing AI on real customer tasks.
- Improve system performance, reliability, security and developer experience.
- Work directly with customers to understand problems, test solutions and iterate quickly.
- Use modern AI development tools to prototype, test and ship software.
What we're looking for
You don't need to meet every requirement. We're looking for strong, product-minded software engineers who are comfortable working across a broad technical surface area.
