Staff QA Automation Engineer

📈 Who We Are:

We are rebuilding the energy transaction, making it transparent and fair.

We're rebuilding how energy is bought and sold. That means cutting out middlemen, connecting businesses directly with renewable generators, and ensuring every transaction is traceable and transparent.

We're a 160+ person team - operators, data scientists, engineers, customer champions and energy experts - backed by top-tier investors including Lightspeed Venture Partners, Hitachi Ventures, Allianz, AlbionVC and Atomico. We closed a $75M Series B round in early 2026, taking our total funding to $94M, and we now power energy for over 4,000 UK businesses across 8,500+ sites, with over £75m in value returned to businesses and generators so far.

We're a technology company solving the energy industry, not an energy company. Some people call us a neo-utility, the neo-bank idea, applied to energy.

The industry is noticing. We were crowned Europe's Most Exciting Tech Company at the GP Bullhound Allstars awards https://www.gpbullhound.com/articles/allstars-awards-2026-winners-announced/, came in at #6 on LinkedIn's Top Startups 2026 https://www.linkedin.com/pulse/linkedin-top-startups-2026-20-uk-companies-rise-linkedin-news-uk-xoffc in the UK, #7 on the Scaling Europe 50 https://scalingeurope.co.uk/ of Europe's fastest-growing companies, and #14 on Sifted's AI 100 https://lnkd.in/p/ehxWgJyc.

The Role

We're hiring a Staff QA Automation Engineer to help shape how quality engineering works across tem.

QA sits inside Platform, a central team that builds the tooling and standards the rest of engineering runs on. You'll design the frameworks and practices that let them test well themselves, and scale into the future. As we scale, you'll lead and develop scripts that equip engineering teams with the automation and standards to own quality themselves.

The product is built on a microservice architecture that brings real complexity to testing. You'll own the quality engineering approach as the organisation scales — setting the standards, building the tooling, and driving adoption across engineering.

What you'll work on:

- A risk-aware CI testing standard any team can run: a dependency model that drives test selection and breaking-change detection, so most PRs get a fast targeted run with a clear confidence signal at the point of change.

- Unit, integration, and contract testing standards with an observability layer that keeps pipelines honest and not flaky. Proven through reference test suites in real service repos, not a QA-authored checklist.

- The quality side of canary releases: working with the wider Platform team to define automated pass/fail analysis against production traffic so deployments promote or roll back without manual sign-off.

- AI in the quality pipeline: LLM-based change-risk classification, targeted mutation testing, test generation, and self-healing checks. We already use LLM tooling across QA and want someone to take it further.

You report to Bartek Kucharski (QA). Specialist individual contributor, no direct reports.

Requirements

Must haves:

- Expertise in test automation frameworks including pytest, Playwright, Selenium, and API testing or similar.

- Experience architecting and maintaining test automation frameworks and tooling used across a wider engineering organisation.

- Deep knowledge of testing across microservice or distributed systems, including API-level automation, CI/CD integration, and service-level testing strategies.

- Experience leading innovation and PoCs in testing, particularly AI-led regression optimisation and change-risk analysis.

- Strong collaboration and delivery focus across multi-project environments and distributed teams.

- Contract testing or consumer/provider verification (Pact, OpenAPI schema validation, or similar).

- AWS infrastructure experience (Lambda, GitHub Actions self-hosted runners, deployment tooling).

Nice to have:

- Progressive deployment experience: canary releases, feature flags, automated rollback from production signals.

- Mutation testing, whether traditional tooling or LLM-based.

- Test-data management and environment-isolation strategy in shared environments.

- Experience in a regulated or high-stakes domain (energy, fintech, payments).

Benefits & Perks

- Our current band for this role is £104,000 or equivalent in local currency.

- We pay against a clear benchmark for your role and level. No fixed once- or twice-a-year cycle - pay moves when the evidence for it does.

- Stock options so everyone has ownership in our mission.

- 25 days holiday plus public holidays. Swap public holidays for the ones that matter most to you, and enjoy your birthday off.

- Remote first within the UK and Europe.

- Home working and wellbeing budgets.

Interview Process

We move fast. Most processes take 2 to 3 weeks from first chat to offer. If you need us to adapt anything, let us know.

- Intro call with Talent, 30 minutes.

- Behavioural Interview with the Hiring Manager, 60 minutes.

- Skills interview with cross-functional leaders, 90 - 120min minutes, including a practical exercise on framework design and AI-in-test.
