About the Company
Sei Labs is a unicorn startup based in NYC building Sei, the fastest EVM blockchain in the world designed for trading. We're building a decentralized Wall Street. We're a lean, remote-first team that ships fast, takes full ownership of outcomes and builds from first principles.
Sei Labs is incubating a new US regulated exchange from zero to one. You'd be the first hire in your function, with the speed and ownership of a startup and the backing of an established company and an S-tier team (Robinhood, Coinbase, Google, etc.)
About the role
As Operations Lead, you will own the daily operating engine of our FCM: making sure every trade, position, margin call, cash movement and customer account is processed accurately, on time and under documented controls. You will be the first-line owner of the trade lifecycle and of back- and middle-office operations. You will work closely with Compliance, Risk, Finance and Engineering, with clear first- and second-line responsibilities. You will build the operating model, write the procedures and run them from day one. As volume grows, you will build the team under you.
What you'll do
-
Trade lifecycle and clearing: own end-to-end trade flow, including trade capture and booking, DCM/DCO and other applicable clearing interfaces, and the daily clearing files, statements and confirmations. Make sure data flows in and out correctly.
-
Reconciliations and exceptions: run daily trade, position, margin, fee and cash reconciliations, and drive breaks to resolution.
-
Margin and positions: run margin processing, margin calls and settlement, and coordinate customer liquidations or position reductions with Risk when thresholds are breached.
-
Treasury and customer funds: operate deposit and withdrawal flows across fiat and stablecoin rails, bank and depository movements, and dual-control approvals. Provide the reconciled cash, margin and customer-account data supporting Finance/CFO segregation and residual-interest calculations, and execute required funding movements under established controls.”
-
Account lifecycle and customer operations: own the handoff from KYC/AML approval into account opening, plus account maintenance, statements and tax-document workflows. Once live, own operational customer escalations.
-
Vendors and resilience: own day-to-day relationships with clearing houses, banks, custodians, funding rails and back-office systems. Run SLAs, incident management and BCP/DR, and lead launch readiness.
