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.
