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.

  • 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.

• 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
