QA Engineer

Who We Are: We're rebuilding the energy transaction system, making it transparent and fair. tem exists to put power back in the hands of people. Today’s wholesale energy market is stacked in favour of the few. It's a product of an age of oil and gas, riddled with markups and middlemen. We’re changing that. Our product, RED™, built on a proprietary pricing engine that bypasses the wholesale market, enables businesses to buy the energy produced by renewable generators directly. That's 100% transparent transactions, ensuring affordable bills and fair compensation, to give every business ownership and control over where their energy comes from. Since launching in 2021, we’ve saved UK businesses and generators over £20 million, powering a growing network of forward-thinking companies, from Pizza Pilgrims to Silverstone.

Deliver confident releases: Lead manual acceptance testing across internal systems and customer-facing products, validating functionality, UX, integrations, and APIs to ensure production-ready outcomes. Drive fast, clear feedback loops: Identify, document, and track defects using structured templates, collaborating with engineers to resolve issues quickly and prevent regressions. Continuously improve how we test: Evolve QA processes, documentation, and tooling - leveraging AI where appropriate - to increase efficiency, consistency, and overall product quality as the team scales.

Requirements: Must-Haves Proven experience owning quality for web products: 3+ years working in a manual QA role where you were responsible for defining test plans and acceptance coverage for complex, user-facing web applications.

Strong written documentation in English: Demonstrated ability to write clear, structured test cases, bug reports, and QA documentation that enables fast understanding and action. Comfortable testing complex domains: Experience validating systems with multiple flows, edge cases, and integrations (e.g. pricing logic, internal tools, APIs, or data-driven products).
