Manual QA Engineer

Who we are

Fluxon is a team of tech leaders from Google, Stripe and top startups, trusted by partners like OpenAI, Anthropic and Zapier to build world-class software products. We embody a startup mindset; working with visionary companies, both large and small, to turn bold ideas into products with real impact.

More important than what we build is how we build it. We are craftspeople who care deeply about quality, clarity, and long-term impact. When we use AI, we do so thoughtfully; applying it where it truly adds value and unlocks possibilities that were previously out of reach.

We bring the same care to our people. Fluxon is a remote, globally distributed team built on trust, strong collaboration, and intentional communication. We invest in meaningful connections, continuous learning, and creating an environment where talented individuals can collaborate as thought partners with industry leaders who feel the same way.

We’re looking for doers who want to grow their craft, take ownership, and solve problems that matter. Let’s build the future together!

Note: This position is fully remote with a strong preference for a candidate based in Poland (Krakow, Wroclaw or Gdansk) or Portugal (Lisbon).
