Software Engineer II - Evening

WHO WE ARE

Headquartered in the historic Chicago Board of Trade, PEAK6 Capital Management is a proprietary options trading firm that has been defining the industry for more than 25 years. While many firms have come and gone, PEAK6 Capital Management has consistently delivered liquidity to the options market. We thrive due to our firm’s special blend of financial acumen, ability to manage risk, and cutting‑edge technology.

Our success is driven by our team of technologists, engineers, and traders who leverage proprietary tech and a data‑centric approach to maintain inventory and stay ahead of the markets, so customers can, too.

We are committed to providing dependable liquidity, which is crucial for market stability, investor confidence, and efficient trading across asset classes.

We are looking for a skilled Engineer to join our core team, initially training alongside our daytime engineers before transitioning to an evening schedule. This role is vital as we grow our services to 24‑hour operation.

Unlike traditional "on‑call" roles, you will be a full‑stack contributor to the same high‑impact projects and core trading systems as our daytime teams, ensuring seamless continuity and system integrity between trading sessions.

As a Software Engineer II a regular day could include working closely with PEAK6’s Finance and Operations team on the systems that power our trading behind the scenes, including PnL reporting, positions, and clearing firm reconciliations. It would also include working collaboratively with other engineers on the team to build out the future of PEAK6’s Finance and Operations software. Additionally, Software Engineers regularly work across teams (engineering, operations and trading) to ensure that their solutions integrate seamlessly to support a great experience for operators in a live trading environment.

• Onboarding:
  You will start on a standard daytime schedule to integrate with the team and master our core systems.

• The Handoff:
  Your day ends with a critical synchronization and system handoff to our Budapest engineering office, ensuring a "follow‑the‑sun" support model.
• Fulltime Remote:

  Tackle complex engineering roadmaps, feature developments, and architectural projects.

  Maintain and support our core trading systems.
