Millennium's Infrastructure organization is dedicated to designing, engineering, supporting, and managing a robust server estate, systems virtualization, and core enterprise services. We are seeking a Senior Platforms Engineer to join a highly specialized team of exceptionally talented yet refreshingly humble individuals from diverse disciplines. We believe that delivering exceptional services requires the ability to make meaningful changes across the entire stack. Our mission is to solve real business challenges, reduce operational complexities, and foster a collaborative, team-driven environment that promotes mutual growth and success.
Responsibilities
- Design, code and implement proprietary systems and tools to help bring research ideas to life, and have a real business impact.
- Collaborate daily with quantitative researchers to understand their needs and turn them into well-engineered solutions.
- Contribute across the stack, primarily in Python with some work in C++.
- Work through complex algorithmic and data-structure problems where correctness and performance both matter.
- Participate in code reviews, design discussions, and promote engineering best practices.
- Communicate trade-offs and technical decisions clearly with both engineers and quants.
Ideal Candidate
- A strong software engineer who cares deeply about code quality, correctness, and clear thinking.
- Someone who enjoys working alongside domain experts and can hold their own in technical discussions on both sides.
- Driven by curiosity, always ready to learn new things and dig into unfamiliar problems.
- A collaborative team player with excellent communication and problem-solving skills.
Required Skills / Experience
- Strong Python skills - you're fluent, idiomatic, and can tackle complex programming challenges with confidence.
- Strong foundation in data structures and algorithms - you can reason about complexity, pick the right approach, and implement it cleanly.
- Demonstrable problem solving abilities, insight, and judgment as well as a strong attention to detail.
- Ability to communicate complex technical concepts clearly with quants and other engineers - this is non-negotiable; a large part of the job is bridging the gap between research ideas and production code.
- Experience working in Linux environment, at an advanced user level.
Preference / Nice to have
- Some C++ experience - you'll be expected to contribute to portions of the codebase written in C++, so comfort reading and writing C++ (or strong willingness and ability to ramp up quickly) is a real plus.
- Prior exposure to quantitative finance, scientific computing, or any environment where engineers work closely with researchers.
- Experience contributing to performance-sensitive or numerically oriented code.

How to prepare for a job interview at Millennium
✨Brush Up on Your Coding Skills
For a full-time software engineering role, it's crucial that we stay sharp with our coding abilities. Expect technical questions that might involve solving problems on the spot or discussing algorithms. Practise on platforms like LeetCode or HackerRank to get comfortable with the types of questions that often come up.
✨Know Your Tools and Frameworks
Make sure we’re well-acquainted with the tools and technologies listed in the job description. Familiarise ourselves with any specific frameworks or programming languages mentioned. If Millennium uses React or Node.js, for instance, be ready to discuss how we’ve used them in previous projects or coursework.
