Last updated: September 2026

I’m Chun Yu, an early-career Linux and systems engineer based in Singapore. Most recently, I worked at Virtu Financial. Before that, I worked on Linux infrastructure at Jane Street and Rust-based production tooling at Jump Trading.

I’m particularly interested in the areas of operating systems, self-hosting,
dirty sysadmin work and embedded systems. my experience covers production debugging, low-latency systems, kernel and systemd issues, eBPF schedulers, performance analysis, and infrastructure automation. I studied computer science at the National University of Singapore.

I have a bad habit of taking on too many projects at once, but i’m trying to get better at that. chat with me via any of my socials. i’ll respond to everyone to my greatest ability, but it might not be quick.

Experience

Some of my past experiences include:

• coreops engineer at Virtu Financial
• techops intern (linux) at Jump Trading
• linux engineer intern at Jane Street
• quality assurance engineer intern at TikTok
• software engineer intern at Rohde & Schwarz x2
• software engineer intern at Fairmart
• teaching assistant for programming methodologies x2 Most recently, I was a core operations engineer at Virtu Financial. I worked with traders and exchanges to diagnose connectivity and market-structure issues, and helped operate a low-latency trading system across global markets.

Before that, I was a Linux TechOps intern at Jump Trading. I extended a Rust coredump tool used across thousands of servers and added reconciliation to an asynchronous Kafka-to-ClickHouse pipeline.

As a Linux engineer intern at Jane Street, I investigated production issues involving the Linux kernel, systemd, and earlyoom. I also automated AWS account creation and machine-decommissioning workflows.

Some of the highlights of my university life include:

• being part of coreteam @ NUS Hackers
• giving workshops on vim, shell scripting, docker and self-hosting @ hackerschool/hackertools
• gave a mini friday hacks talk @ Friday Hacks
• spent a year heading RHDevs, a small developer group in Raffles Hall

What I’m looking for

I’m looking for a full-time role in systems software, infrastructure, performance engineering, or developer tools. Work close to the kernel is my strongest interest, but the real draw is a hard technical problem with enough depth to follow it through the stack.

I value teams with experienced engineers, clear technical writing, honest feedback, and real ownership. I’m comfortable joining an established codebase when there is plenty to learn from it, and I also enjoy building new tools when the problem calls for one.

I’m open to working in person, remotely, or in a hybrid team, and I am willing to relocate. As a Singapore citizen, I am eligible for the US H-1B1 visa.

If that sounds relevant, the best way to reach me is email. You can also find my code on GitHub or connect with me on LinkedIn.
