We are an independent, private trading desk operating predominantly in US financial markets. We keep our team small, collaborative, and focused entirely on the craft of trading: disciplined risk management, curiosity, and continuous refinement.
You won’t find layers of corporate bureaucracy, hollow buzzwords, or office politics here. We value a relaxed, collegial atmosphere where open discussion is encouraged, trial-and-error is treated as part of the process, and everyone works closely together with high accountability.
We are looking for a Portfolio Manager Assistant to work directly alongside the Portfolio Manager in our Sofia office - assisting with daily book operations, hunting for setups, managing counterparty relationships, and constantly exploring ways to make our desk run sharper.
€1,750 net / month. This year is dedicated to intensive, one-on-one desk training where you learn our strategies, risk frameworks, and execution mechanics.
