Quantitative Developer

About Us

• Spotted Owl is a trading team of about 30 people, started in 2024 and led by Douglas Schadewald and Daniel Spottiswood. We trade all asset classes globally, with a focus on options.
• We are made up of developers, researchers, and traders, although the roles are quite fluid. Everyone on the team writes and ships code.
• Our primary office is in New York. We also have people in Zurich, Singapore, Hong Kong, London, and Austin.

The Role

• The Quantitative Developer role on our team has evolved substantially in light of recent AI developments.
• Developers now focus on the larger architectural problems: the platforms and core tools that power the team's workflows, and their speed, reliability, and safety.
• Developers also maintain our live trading systems and work with our traders throughout the trading day.

How We Work

• Like a startup. We do not have a slow-moving ticket queue or product managers. We resolve problems quickly and aim to ship the same day.
• AI-native. AI agents are central to how we build. The value of the developer is directing agents to work on the right tasks and holding their output to a high standard.
• Immediate ownership. The team is lean. You will very quickly lead projects which directly impact trading.
• In office. We work from our Hudson Yards office every day. Traders, researchers and developers all sit right next to each other.

Our Stack (any is a plus)

• Python (Polars), Linux
• Redis, Postgres, ClickHouse, Iceberg, Airflow
• TypeScript / React
• Rust, C++

Preferred Experience

• 3+ years of experience as a software engineer
• Experience in trading or finance
• Very strong in Python
• A software engineer first. This is not an options pricing or modeling role.
• AI-first mentality
