(Senior) QA Engineer - AI-Driven Testing (m/f/d)

1KOMMA5°

At 1KOMMA5° , we pursue a clear vision: Living on wind and sunlight forever for free . To make this a reality, we are building the energy system of the future with Heartbeat AI. Want to be part of it?

We bring together regional craftsmanship and scalable software: We don't think of solar, batteries, heat pumps, and e-mobility as isolated components, but control them as an intelligent, integrated overall system in our virtual power plant. Directly connected to the electricity market – in real time, fully automated.

This way, energy is used when it is available from renewables and particularly cost-effective. By 2030, our goal is to transition 1.5 million households to renewable energies. Over 3,000 people are working towards this every day, at more than 80 locations worldwide, from Finland to Australia.

Want to take responsibility and build solutions that truly matter? Apply now and help us shape the energy world of tomorrow.

Deine Position

As part of one or two cross-functional mobile product teams, you will own the quality of our Flutter apps, and change how we approach testing.

AI-driven QA is the differentiator in this role. Our QA team already uses AI for test generation, but we want to go much further. You will help invent this from scratch: autonomous exploration, smarter test orchestration, self-directed QA workflows, and QA systems that detect product risks before they reach users.

This is not a "write test cases and file tickets" role. You co-own product quality end-to-end, tell engineering teams where the gaps are, and build the systems and practices that let us ship with confidence. Faster, not slower.

You think about quality as something you design into the product and process, not a checklist you run before release.

Our Stack

Flutter & TypeScript

Appium, BrowserStack

Testmo for test case management

GCP, GitHub Actions, Datadog

AI-assisted development with Cursor and agentic coding workflows

Linear, Notion, Figma, Miro

Key Responsibilities

Own quality across our mobile products end-to-end: test strategy, execution, and production monitoring

Work embedded in one or two cross-functional product teams and shape quality practices with engineers, product, and design

Find the gaps in our current testing approach and close them

Grow and maintain our automated test suite (Appium / BrowserStack). Keep it fast, stable, trusted, and focused on critical user journeys

Advise engineers on testing strategy and testability early, at the design stage, not after the build

Push AI-driven QA beyond test generation: bring in autonomous exploratory testing, intelligent orchestration, and self-directed testing workflows

Build QA feedback loops that are tightly integrated with development. Quality should be a real-time signal, not a gate at the end

Keep test infrastructure healthy: less flakiness, faster runs, results the whole team can act on

Use AI tools wherever they make you and the team more effective, and figure out where autonomous QA can reduce repetitive manual work while preserving human judgment where it matters

Dein Profil

5+ years of QA experience across manual testing, automation, and test strategy.

Hands-on experience with mobile test automation (Appium or comparable) and cloud device farms (BrowserStack or similar)

Experience integrating automated testing into CI/CD pipelines (we use GitHub Actions) and using quality signals to support rapid, reliable releases

Strong understanding of mobile application architecture, client-server interactions, and API integrations, with a feel for common mobile failure patterns

You understand the SDLC and can design test strategies around how complex products fail

Practical experience leveraging AI in QA workflows such as exploratory testing, test case design, defect analysis, and autonomous testing agents. Or you have a clear vision for it and can show you've been building in that direction

You care about user journeys and real-world scenarios, not just code coverage numbers

Comfortable with ambiguity. You figure out the path forward when there's no playbook

Clear communicator in written and spoken English

Bonus points for

German language skills

Experience with energy systems, IoT, or climate tech

Startup or scale-up experience

Hands-on experience with LLMs or AI agents in a QA or DevEx context
