Intern - Finance Engineer

About the role

This 12-week New York internship offers practical experience in financial engineering within LSEG’s Optimisation Strats Team. Interns work with experienced engineers to develop algorithms, optimisation models, data-processing logic, validation checks, and transaction proposals that improve derivatives portfolio services and products.

Role and Responsibilities

• Design and implement improvements to optimisation services with a team of four to six financial engineers.
• Develop algorithms for linear, mixed-integer, and convex optimisation problems supporting derivatives portfolio improvements.
• Build data-preprocessing logic, post-processing validation checks, and proposal-generation functionality for large datasets.
• Collaborate with Product Development to enhance products using client feedback, run analysis, and strategic projects.

Example Projects

• Develop scaling schemes to improve optimisation reliability and performance.
• Introduce mixed-integer models to achieve rounded solutions.
• Analyse solution sensitivity to data changes and identify constraints to relax for maximum impact.
• Refactor code to share functionality and business logic across assets.
• Improve runtime performance using heuristics to reduce datasets and solution search spaces.
• Develop functionality to validate incoming client data before optimisation.

Requirements

• Penultimate-year undergraduate or final-year undergraduate student planning to continue onto a master’s degree in 2027/28.
• Studying mathematics, physics, engineering, computer science, or another quantitative field.
• Experience with Python; familiarity with pandas and NumPy is advantageous.
• Strong mathematical background in numerical methods, linear algebra, probability, and statistics.
• Basic understanding of linear or mixed-integer programming and convex optimisation.
• Excellent problem-solving skills; financial products knowledge and UNIX familiarity are advantageous.

Recruitment Process

• Submit an application and resume; candidates should submit only one internship application.
• Complete technical and coding assessments evaluating coding ability, logical reasoning, and problem-solving skills.
• Complete an untimed immersive online assessment about working at LSEG.
• Attend a strength-based video interview followed by a virtual half-day assessment centre.
• Assessment centres are conducted virtually, with further exercise information provided upon invitation.
