We're searching for passionate individuals eager to contribute to Alpaca's rapid growth. If you align with our core values—Stay Curious, Have Empathy, and Be Accountable—and are ready to make a significant impact, we encourage you to apply.
As a Staff Software Engineer, you will be responsible for architecting, designing, and implementing the systems and services that form Alpaca's foundation and empower millions of users who trade billions of dollars worth of assets. You will serve as a technical leader with extensive influence that goes beyond the immediate team to affect the entire product's technical direction. You will be the founding technical lead for Singapore and the broader SEA region: leading regional recruitment, leading cross-functional projects, mentoring talent on our engineering principles and practices, and fostering Alpaca culture in the region. As the lead, you will also serve as the operational reliability and engineering lead and the incident commander during regional business hours, ensuring proactive 24x7 stability.
For this role, we are seeking a backend engineer who has built the middle- and back-office systems that are a broker-dealer's system of record — customer account management and KYC, pre-trade controls such as buying-power validation, post-trade processing, double-entry ledgers and books-and-records, clearing and settlement, custody, corporate actions, reconciliation, and regulatory reporting — for a firm serving end investors. This is not a front-office trading-systems role: experience limited to sell-side market-making, low-latency/high-frequency execution, quantitative trading strategy, or exchange-side trading infrastructure is not sufficient on its own. The ideal candidate has a track record of architecting solutions that span multiple products or services, acts as a mentor and consultant providing strategic technical insights, and can take a platform into new markets repeatedly as Alpaca expands across SEA.
Alpaca is proud to be an equal opportunity workplace dedicated to pursuing and hiring a diverse workforce.
