Job description

Senior Software Engineers. High-Frequency Trading. Sydney, Hong Kong, Singapore.

elite HFT firm across Sydney, Hong Kong and Singapore. Big tech L5+ engineers only. All conversations confidential.

• Flat structure, exceptional team
• Deep technical problem solvers

If you’ve never worked in HFT, here’s what most engineers don’t realise until they’re in it: the problems are some of the most technically demanding in existence. Latency measured in nanoseconds, systems that have to be right the first time, and software where the margin between good and exceptional is worth millions. No other industry asks this much of its engineers, and if you’re the kind of person who’s wired for that, nothing else will ever feel quite as sharp. They’re selective to the point of being difficult and that’s precisely why I’m talking to you. If you’re a big tech L5 or above and you’re ready for a different kind of hard, this is worth three minutes of your time.

What they need from you

• L5+ big tech or comparable. Not internal tech teams, not consulting arms, not “tech-adjacent”
• A track record of solving genuinely hard, deep technical problems. The kind with no obvious answer
• Someone who works autonomously and thinks for themselves. Direction-takers need not apply
• Language-agnostic. They care about how you think, not which syntax you prefer
• Ego left at the door. You’ll be surrounded by very smart people and expected to learn from them

What they’re offering

• Genuinely flat structure. No layers, no politics, no performance theatre
• A team of exceptional individual contributors who take their craft seriously
• Problems you will not find anywhere else
• Five days in-office. This is non-negotiable and entirely intentional
• Full relocation package and visa sponsorship, wherever you’re coming from

A note on fit: this client is stoic about culture. If you’re used to a big org structure, ownership ambiguity, or a team that debates before it builds, this will be an adjustment. The upside: if you thrive without that scaffolding, you’ll do the best work of your career.

Tech stack: Language agnostic, C++ valued, Python valued, OCaml a bonus

Base: Highly competitive. Will match or beat your current package

Bonus: Discretionary. Significant upside for the right performers

Sign-on: Available

Relocation: Full package and visa sponsorship included
