Trading System Support Engineer

As a Trading System Performance Engineer at All Options, you will play a key role in ensuring the stability, performance, and continuous improvement of our trading systems. Operating at the intersection of development and real-time support, you will help optimize our trading environment while directly contributing to the success of our trading operations.

Unlike a traditional Software Developer role, this position combines engineering with hands-on operational responsibility. Your time will be split between performance-focused development work and an active support rotation, where you take ownership of live issues as they arise. While you will build tools and automation to improve our systems, you will also embrace a dynamic environment with frequent context-switching and real-time problem-solving.

From day one, you will work closely with traders and engineers on the trading floor, staying close to critical systems and the people who rely on them. Rather than focusing purely on feature development, you will be motivated by impact—whether that’s resolving urgent production issues, enabling smooth trade execution, or investigating complex system behavior to identify root causes.

This role requires a proactive and analytical mindset, balancing immediate operational needs with longer-term performance improvements. You will contribute to enhancing system architecture, monitoring capabilities, and automation, ensuring our trading platform remains robust and efficient under high-pressure market conditions.

This is a high-impact role where your work directly influences system reliability, trading performance, and the firm’s ability to operate effectively in fast-moving markets.

Key Responsibilities

• Provide daily support for proprietary trading systems, diagnosing and resolving critical production issues, and managing incident tracking and reporting;


• Develop scripts and tools to automate system tasks and operational processes;


• Build and enhance monitoring tools and dashboards to correlate system performance with trading outcomes, including alerting and automation;


• Improve system uptime, capacity, and performance to ensure stability under high-load and high-volatility market conditions;


• Analyze protocol messages and optimize system components such as position requests and instrument filters;


• Continuously review and improve system architecture and performance;


• Coordinate and execute corporate actions across teams within the trading system;


• Coordinate, test, and support exchange upgrades and go-lives;


• Manage user accounts, roles, and access rights within trading systems;


• Maintain trading session configurations across exchanges;


• Define, document, and improve operational procedures and best practices.
  

Key Requirements

• Strong experience with UNIX/Linux systems (L2/L3 support) and a solid understanding of networking fundamentals;


• Proficiency in scripting and automation (e.g. Python, Shell) and experience with version control systems such as Git;


• Experience writing SQL queries (preferably PostgreSQL);


• Strong analytical and problem-solving skills with attention to detail;


• Excellent communication skills and the ability to collaborate effectively in a fast-paced environment;


• Experience with trading systems (e.g. Bloomberg, Tbricks, Quik) and exchange protocols (e.g. FIX, ETI, Optiq, EMDI) is a plus;


• Experience with C++ is a plus;


• Previous experience in a financial or trading environment is a plus;


• Willingness to work flexible hours when required.
