## Job description

## ABOUT US

Imagine building systems that think in microseconds — algorithms that move millions with absolute precision.

We’re engineers driven by performance, reliability, and meaningful innovation in the crypto trading space. Our team — experienced builders from Amazon, and Google, with academic backgrounds from Berkeley, Caltech, ETH, and MIT — is developing a next-generation trading platform that executes orders seamlessly across 10+ exchanges and dozens of tokens.

Here, every line of code matters. Push your work to production, and within minutes it could be driving thousands of trades per hour. It’s fast, impactful, and never dull — the kind of engineering challenge that keeps you sharp and inspired.

## WHAT YOU'D BE SECURING

We execute roughly $5 billion in volume every day, across thousands of assets, on dozens of exchanges, 24/7/365. Our algorithms price and hedge thousands of trades per second. We have a DeFi team operating on-chain. We run OTC. We have signing keys, exchange API credentials, quant models, and proprietary strategies. Blackhats around the globe know that too. We need someone who looks at that and sees an interesting problem — and has the skills and grit to hold the right defenses.

## THE ROLE

You'll join a small, senior security team. No checkbox security, no bureaucracy — just real problems and the ownership to solve them. Plan and execute projects to evolve and upgrade our defenses or create new ones. Sometimes it’s setting a right rule for “can I share this document” and sometimes it’s responding to an attack by a state sponsored actor. Part of the job is on-call rotation. During your on-call week, you may get pulled into an incident or an urgent question outside working hours.

## MUST HAVE

- 5+ years of cybersecurity and devops or relevant experience
- Familiarity with software development security: pipelines, artifact registries, supply chain attacks, dependency confusion, slopsquatting
- Hands-on Cloud security
- Solid, hands-on experience with AI tooling and their risks
- Current on the threat landscape: you know what's being exploited now, what defenses are effective, and what's still hype
- Clear, structured thinking about risk — threat modeling, prioritization, communicating tradeoffs to non-security people
- Self-directed. Manager of one https://signalvnoise.com/posts/1430-hire-managers-of-one.

## STRONG ADVANTAGE

- First hand experience with incident response
- Understanding of crypto fundamentals, — not necessarily a developer, but you need to reason about the risk surface
- DeFi experience and understanding
- Experience in trading, fintech, or any environment where security controls must coexist with latency requirements
- Hands-on Google Workspace security
- 10+ years of cybersecurity and devops or relevant experience
- smart contracts, and L2 protocols
- Has personally owned cloud security at a real production scale (AWS)

## INTERVIEW PROCESS

Introductory Call (35 min, online) An introductory conversation to discuss your background, the role, and answer any initial questions.

Interview #1 – Experience Deep Dive (60-75 min, online) A discussion focused on your technical experience and real-world examples from your previous work.

Interview #2 – Problem Solving (2.5–3 hours, Bratislava on-site) An on-site interview focused on technical scenarios and collaborative problem-solving.

Interview #3 – Company Fit (60-75 min, Bratislava on-site) A final conversation to get to know each other better and ensure it's the right fit for both sides.

Help us protect a firm that moves billions a day. If that sounds like your kind of challenge, we'd love to hear from you.
