Job Description:
Staff Security Engineer Confidential | Sydney or Singapore | Global Options Available
Experienced hire only. This is not an entry point role.
A tier-one HFT firm is seeking a Staff Security Engineer to work alongside some of the best engineers in the industry — building and driving a highly resilient security infrastructure in one of the most technically demanding environments on the planet.
There's nowhere to hide in HFT. Everyone is technical, everyone is an IC, and the bar is genuinely high. You'll work directly across trading and technology teams, operating with a high degree of autonomy and contributing at a level that moves the needle.
The right person is genuinely curious — someone who wants to operate at the absolute top of their game. The compensation is exceptional, but if that's your primary motivation, this probably isn't the right role. What you'll be exposed to, and what you'll learn, is the real drawcard.
𝗪𝗵𝗮𝘁 𝘆𝗼𝘂 𝗯𝗿𝗶𝗻𝗴
→ Strong programming skills for automation — Python, Go, or equivalent → Deep Linux knowledge — shell, system troubleshooting, and beyond → Network security fundamentals: DNS, SSL/TLS, IP stack, end-to-end trust → Threat and vulnerability management experience → Secure identity management and authentication principles → A high standard for quality and a bias toward continuous improvement → Reliable, predictable availability and the ability to work across stakeholders independently
𝗪𝗵𝗮𝘁'𝘀 𝗼𝗻 𝗼𝗳𝗳𝗲𝗿
→ Tier one HFT compensation — all cash, base plus bonus, sign-on, and unvested shares paid out → Full relocation package and visa support if required → NCs paid out — we'll make the move worth it → Sydney, Singapore, or global placement consideredYou'll be coming from a Staff level or above at a big tech firm or a tier-one HFT firm.
𝗡𝗼𝗻-𝗻𝗲𝗴𝗼𝘁𝗶𝗮𝗯𝗹𝗲𝘀
5 days in the office. Travel required. A rigorous, multi-stage interview process. If you're the right person, you already expected this.
Ready to have a discreet conversation? Call or message me on +61 434 277 104 — but please only reach out if you've read the requirements and you're a genuine fit.
