Values & How we work?

The entire crypto space doesn't just move fast but is constantly accelerating. It’s hard building a DeFi product — it’s 24/7, 365 days a year, markets do not close, the ground beneath you can shift, assumptions can and do fail & risk of burning out is real.

  • We take our product + brand very seriously.

    • If we see even a small flaw in our product, we always ask ourselves - Why isn't this perfect?

    • All members have perpetual autonomy to fix anything broken that we notice, and we do not wait for someone else to tell us what to do.

  • Take extreme ownership of everything we do

    • If the team fails, everyone fails, so prioritize and execute.

    • We think long-term, set big goals, and communicate with clear directions and goals to achieve them. Everyone must understand not just what they're doing but also why they are doing it.

    • No Egos, lead by example, and mutual accountability.

  • Strive for clear and simple communication - this is easier said than done but communicating the "why" of an issue is equally important as the "what.”

  • All meetings have an agenda, with outcomes clearly defined as tasks and call-to-actions.

  • Prioritize all tasks by - what is more important for our users without compromising on any of the above goals.

What we Offer

  • Unique opportunity to work with a small, focused & ambitious team on very interesting projects and get the level of responsibility and ownership that would be unlikely at any other project.

  • Great company culture: informal, non-hierarchical, ambitious, highly professional yet collaborative and entrepreneurial

  • Sense of a Shared Mission

  • Work on the latest technology, equipment, and web3 stack with dedicated budgets

  • Flexible working hours

  • Annual team retreat

  • Competitive compensation
