Application Engineer - IV

Join an elite team providing front‑line operational and production support to Vanguard’s U.S. Equity Trading Desk. You’ll work directly on the trade floor with traders and portfolio managers, supporting mission‑critical applications that power daily equity, ETF, and derivatives trading across more than $6T in assets and ~$160B in quarterly volume. This developer role sits on the GIFS Desk Development Team within the Run Organization, delivering rapid business value through custom solutions and hands‑on problem solving.

You’ll build and maintain modern, high‑performance systems while partnering closely with Portfolio Managers, Traders, Product Owners, and Investment Management teams. You will also be troubleshooting and helping resolve problems that occur on our trading platforms.

The Run Organization ensures trading systems “just work,” monitoring applications and resolving over half of the issues that occur independently. This role is primarily in‑person in Malvern, PA, with follow‑the‑sun handoffs to global teams. Supported technologies span custom builds, COTS, SaaS, AWS microservices, and legacy platforms including MS Office programming tools. Ideal candidates bring a strong blend of technical and business acumen, curiosity to learn the trading lifecycle, and the ability to troubleshoot complex systems.

Experience in investment technology is preferred but not required. This is a rare opportunity to gain a front‑row view of Vanguard’s core investment engine, learn directly from industry leaders, and build skills that open doors across Vanguard and the broader financial services industry.
