Let’s turn Europe’s energy flexibility into reality, at scale.

The biggest change in Europe’s energy system is happening now, behind the meter. This is the moment to shape the future. Together, at Qynn.

See the open role

Batteries, heat pumps, chargers and machines on thousands of commercial and industrial sites could make Europe’s energy system far more flexible.

Most of that flexibility never gets built: the market isn’t set up for it, and site owners don’t want to carry energy market risk.

Founded in 2025 in Zurich and Munich, Qynn changes that.

European energy companies already use our platform to design, sell and operate flexibility-based tariffs under their own brand.

And when demand can follow supply, the grid can take in more solar and wind power, and electrifying heating and transport gets easier.

Every site that runs better behind the meter with Qynn adds to that.

What we build

One platform takes an energy company from the first lead to the final invoice.

  1. Sell.

    Simulate a site, size its assets, build the investment case and price the tariff.

  2. Onboard.

    Connect almost any energy asset on site automatically and qualify it for the markets.

  3. Operate.

    Optimise and dispatch thousands of assets in real time across energy markets.

  4. Bill.

    Settle, invoice and prove the savings.

It covers power, heat and cooling, runs multi-tenant and white-label, and comes with an agentic toolset that lets our customers move much faster.

How we work

  • Slow is smooth, smooth is fast.

    We take the time to do things properly. That is what makes us fast.

  • Scientific and neutral.

    We test assumptions with data and judge ideas on their merits, not on who brought them.

  • Open to ideas, quick to prioritise.

    Every idea is welcome. We decide quickly which ones we pursue now.

  • Closer when it gets harder.

    When things get difficult, we move closer together.

  • Focus on the essential.

    We do fewer things, and do them properly.

What we look for in everyone

  • You’re AI-native. You work with agents and automations every day, review what they produce critically and know where they fail. You have a view on where AI takes software and company building next. We don’t hire without this.
  • You learn fast. Our product covers a lot of ground, and you become useful in it quickly.
  • You communicate clearly. You explain problems, ideas and trade-offs precisely and briefly. When agents do much of the work, this matters more than ever.
  • You work systematically. Agents amplify whatever process you have, good or bad.
  • You think in product. You set priorities, talk to customers and own a surface or a problem end to end.
  • You have sound judgement. You see the big picture and get the small decisions right.
  • You care about the energy domain. Energy flexibility, markets, simulation and optimisation. Experience helps; curiosity is a must.

Ticking every box matters less than how you think and how fast you learn. If you see yourself in most of this, apply.

What we offer

  • Ownership from your first week. A surface or a problem that is yours, end to end.
  • Equity. Everyone who joins now gets ESOP shares, so when Qynn succeeds, you do too.
  • A fair salary, stated in every posting.
  • 30 days of vacation.
  • Remote-first, with time together. We have a strong remote-first culture, and we know that meeting in person matters, especially in your first months. That’s why we work from our Zurich office two to three days a week. Part of the team is in Munich, and we all meet regularly for workshops and offsites.
  • Hard problems that matter. Few startups get this mix: real electricity and real energy assets, run by software and AI that scale.
  • Short paths. Decisions take hours, and you talk to customers directly.
  • Openness. We share numbers, plans and decisions with the whole team.

What we don’t offer: a quiet ride. Ownership is high, the pace is high and priorities change. We’d rather tell you now.

From application to offer

  2. Review.

    A person reads every application.

  3. Intro call.

    30 minutes about the role and your questions.

  4. Deep dive.

    A task, a code walk-through or a pairing session, depending on the role.

  5. A day with the team.

    You spend a day with us in Zurich and work on a real task with the people you would work with. Both sides learn more in that day than in any interview.

  6. Offer.

    A written offer, and a call to go through it together.
