Performance Engineer

As a Performance Engineer at IMC, you will play a pivotal role in analysing, optimising, and tuning our systems interaction with exchange systems holistically. Working closely with cross-functional teams, you’ll be tasked with uncovering performance improvements across the trading stack. This role combines technical ingenuity with creative problem-solving to outsmart competition in one of the most demanding technical landscapes.

Your Core Responsibilities

• Black Box Reverse Engineering and Analysis: Analyse and understand the behaviour of complex systems using black-box techniques, identifying performance bottlenecks and optimisation opportunities. Designing and performing statistical experiments to explain emergent real world phenomena.


• Quantitative research: use large datasets to understand exchange technology.


• Experimentation & Prototyping: Design, implement, and test innovative ideas, experiments and technologies. Develop quick internal prototypes to evaluate performance and real-world applicability.


• Collaboration & Communication: Liaise effectively with traders, software and hardware engineers, and infrastructure teams to share insights and implement solutions.


• System Analysis: Analyse terabytes of network data to identify patterns, validate hypotheses, and optimise system performance.

Your Skills and Experience 

• Proficient understanding of computer internals, networking and Linux (at least two out of three). Skilled in reverse engineering techniques.


• Inquisitive mind. Think Sherlock Holmes and the case of the missing microsecond.


• Understanding of complex, bespoke networks and networking stacks.


• Experience with data and system analysis in Python


• Be able to work self-sufficiently with minimal guidance after internal training


• Capable of working autonomously while contributing to a multidisciplinary team. Always looking for ways to gain an edge.
