Head of Operations

Ostium is on a simple mission: make it possible for anyone with a digital wallet to trade stocks, commodities, currencies, and crypto with full transparency. No brokers, no freezes, no hidden spreads. We’re replacing the opaque, offshore brokerage model with a transparent, permissionless trading stack built onchain. Every trade, deposit, and withdrawal is verifiable through open, auditable code. We’ve raised $27.9M+ from General Catalyst, Jump, LocalGlobe, Susquehanna (SIG), GSR, Alliance DAO, Soma Capital, Balaji Srinivasan, Meltem Demirors, and others.

We’re hiring our second full-time operator to scale our core business operations. You’ll work directly with our CEO and Chief of Staff to own company-critical execution across compliance, financial operations, recruiting, and strategic relationships with major liquidity venues, exchanges, and infrastructure partners. You’ll take on big problems from day one and build the operational engine that powers a globally accessible exchange taking on a market doing over $10T of notional volume per month.

• Own financial discipline: payroll, treasury operations, vendor management, spend controls, and investor reporting

• Lead people operations: hiring pipelines, onboarding, performance systems, and internal communication rhythms

• Maintain compliance and regulatory operations in partnership with counsel and external vendors

• Support trader onboarding and lifecycle to ensure fast resolution of any blockers

• Work cross-functionally with engineering and product to maintain execution quality and unblock dependencies

• Make sure nothing breaks without a plan: flag issues early and push improvements through to completion.

• 2-5+ years in high-growth fintech, exchanges, banking, consulting, or trading-adjacent environments

• Obsessed with operational precision - nothing slips

• Analytical and proactive - you notice inefficiencies and fix them fast

• Exceptional communicator with strong writing and relationship building skills

• Able to operate in high-stakes environments with real capital and regulatory exposure, including direct coordination with legal partners across immigration, employment, fundraising, and compliance.
  

• Work directly with founders building the future of transparent, trader-first financial infrastructure

• Ownership over complex, high-stakes problems from day one

• We offer salaries at the top of the benchmarks you’d find for senior roles at big name companies

• We provide equity to all employees regardless of role. We are looking for people who can grow with us as we scale our team and product, and we think it’s important for all employees, especially our first few teammates, to have significant equity in the company so you have skin in the game and our incentives are aligned
