Quant engineers build the infrastructure that powers algorithmic trading. They're not researchers (they don't find alpha). They're not traders (they don't execute trades manually). They build the systems that make it all work. Here's what they actually do all day.
Morning: Check Production Systems
First things first:
- ✦ Check overnight P&L and system health dashboards
- ✦ Investigate any alerts from trading engines
- ✦ Review market data feed integrity
- ✦ Check that risk limits weren't breached
- ✦ Ensure all systems are ready for market open
Midday: Build & Optimize
The core work:
- ✦ Implement new exchange connectivity (FIX protocol, WebSocket feeds)
- ✦ Optimize order execution paths (reduce latency by microseconds)
- ✦ Build backtesting infrastructure for researchers
- ✦ Improve risk management systems
- ✦ Write lock-free data structures for market data processing
Afternoon: Collaborate & Deploy
Team coordination:
- ✦ Review pull requests from other quant engineers
- ✦ Deploy new features to staging environment
- ✦ Run performance benchmarks
- ✦ Collaborate with quant researchers on implementation feasibility
- ✦ Document system changes for compliance audits
Required Skills
- ✦ C++ or Rust for low-latency systems
- ✦ Python for research tools and glue code
- ✦ Understanding of networking (TCP/UDP, multicast, kernel bypass)
- ✦ FIX protocol knowledge
- ✦ Linux systems programming
- ✦ Concurrency and lock-free data structures
Production Responsibilities
- ✦ Monitoring trading infrastructure
- ✦ Managing system reliability
- ✦ Investigating latency regressions
- ✦ Supporting deployment processes
- ✦ Maintaining auditability requirements
- ✦ Responding to production incidents
Organizations That Commonly Hire Quant Engineers
- ✦ Proprietary trading firms
- ✦ Market makers
- ✦ Hedge funds
- ✦ Exchanges
- ✦ Fintech infrastructure providers
- ✦ Institutional trading platforms
