Mercury is a fintech platform providing banking, treasury, and financial workflow solutions for startups and technology companies. The company is seeking a Senior Engineering Manager to lead the Custody team through its next phase of growth and scale.
In this role, you will lead, hire, and develop a team of senior engineers while fostering a trusting and supportive environment. You will own the team's technical strategy and roadmap, translating Mercury's investment ambitions into focused priorities and predictable delivery. You will guide the design and evolution of core custody systems, including cash and securities ledgers, security master service, position tracking, and reconciliation.
Key responsibilities include partnering with product, investment operations, and compliance teams to turn business and regulatory requirements into well-designed systems, operational controls, and auditable workflows that balance correctness, scale, and maintainability. You will collaborate with Product and Partnerships to align integrations, responsibilities, and technical roadmaps. You will set a high bar for correctness, reliability, and incident response, balancing new capabilities with the maintenance and improvement of critical systems.
The role offers the opportunity to work on foundational financial infrastructure that powers investment and custody operations at scale, similar to the electronic clearing systems and DTCC infrastructure that transformed markets in the 1970s.
**Requirements:**
- 3+ years of experience managing highly technical teams
- Direct experience building or operating RIA and broker-dealer custody systems at scale, including ledgers, security master service, cash and securities reconciliation, and money movement
- Understanding of the broker-dealer operating model and how responsibilities and data flow across introducing brokers, clearing firms, and custodians
- Experience working closely with compliance and operations teams, translating requirements into practical engineering decisions and effective controls
- Understanding of the lifecycle of securities and the implications of settlement and corporate actions for customer cash and positions across equities, fixed income, ETFs, and mutual funds
