# Principal Security Engineer at Auros

- **Company:** Auros
- **Location:** United Kingdom / Europe
- **Work type:** remote
- **Posted:** 2026-02-10
- **Last confirmed live:** 2026-09-10
- **Apply:** https://job-boards.greenhouse.io/aurosglobal/jobs/4659762005

## Job description

Location: Remote UK/Euro Reporting line: Chief Risk Officer

## About Auros

Auros is a global digital asset liquidity provider operating 24/7 across centralised and decentralised markets. We run high-availability, low-latency systems where resilience and risk discipline matter. Security is treated as a core engineering and risk function, with direct engagement from senior leadership.

## The Role

We're hiring a hands-on principal security engineer to implement and operate security controls across our infrastructure. This is a technical execution role where you'll be writing code, configuring systems, and shipping security improvements, not writing policies or managing people.

You'll work closely with Infrastructure and Engineering teams to harden our cloud environments, secure our CI/CD pipelines, and protect both corporate and production systems. The scope is broad, the environment is fast-paced, and you'll be expected to own problems end-to-end.

We believe security should enable the business, not obstruct it. You'll design controls that are effective but unobtrusive, security that works in the background without creating friction for engineers or traders.

## What You'll Do

- Implement and maintain security controls across multi-cloud environments (primarily AWS and Azure, with some GCP and AliCloud) and on-prem infrastructure
- Own IAM strategy and implementation: design and enforce identity, access, and permissions models that are secure, scalable, and practical
- Design and operate key management and custody security controls such as HSMs, secrets management, and secure key handling for trading operations
- Harden CI/CD pipelines (GitLab) and secure the software delivery process
- Configure and operate corporate security tooling (endpoint protection, MDM/Jamf, DLP, identity management)
- Respond to security incidents: triage, investigate, contain, remediate
- Conduct security assessments of infrastructure and applications
- Automate security operations: detection, alerting, and response
- Work with Infrastructure to embed security into cloud provisioning and system configuration

## What We're Looking For

- 8+ years' hands-on experience in security engineering or security operations
- Strong, opinionated views on IAM (you've designed and implemented identity and access management across cloud environments and have a clear philosophy on how it should work)
- Strong working knowledge of cloud security controls across multiple providers (AWS and Azure preferred)
- Experience securing CI/CD platforms, GitLab preferred
- Familiarity with corporate IT security tooling (Jamf, endpoint protection, DLP, SSO/IdP)
- Comfortable in Linux environments and scripting (Python, Bash, or similar)
- Experience with infrastructure-as-code (Terraform, Pulumi etc.) is a plus
- Exposure to financial services, crypto, or other regulated environments is a plus but not required

We value demonstrated skills and practical experience over certifications.

## What You Get

- Direct ownership of security implementation
- A small, technical team where your work has immediate impact
- Exposure to low-latency trading infrastructure and the digital asset space

## About Auros

## Company Overview
- **One-liner**: Auros is an algorithmic trading and market making firm that delivers liquidity for digital asset markets, combining proprietary high-frequency trading strategies with partnership-based liquidity solutions.
- **Entity Type**: Private (funding stage: Venture; total funding $17M as of March 2023)
- **Headquarters**: Hong Kong, Hong Kong
- **Founded**: 2019
- **Founders**: Not publicly listed on the website or LinkedIn; leadership team includes Marcel Klooss (CEO), Jason Atkins (Head of Trading), Le Shi (CTO), Brian Norman (CFO), and others.

## Core Business
- **Primary industry/industries**: Algorithmic trading, market making, liquidity provision in cryptocurrency and digital asset markets (Capital Markets).
- **Target customers**: Crypto exchanges, token projects, institutional investors (B2B).
- **Mission or purpose statement**: “Making Digital Markets Liquid” – ensuring token stability and market efficiency through algorithmic precision and advanced technology.

## Products & Services
- **[Auros Trading – Proprietary Trading]**: High-frequency trading engine that powers internal strategies and provides liquidity across major venues globally. Type: Algorithmic trading infrastructure.
- **[Auros Liquidity Solutions]**: End-to-end service for token projects – from venture funding and engineering support to token launch, liquidity strategy, and institutional market expansion. Type: Service + technology.
- **[OTC Trading]** (implied by job listing on Greenhouse): Over-the-counter trading desk for large block trades. Type: Service.

## Market Standing
- **Valuation/Market Cap**: Not disclosed (private company).
- **Key Metric**: $18.21B total trading volume YTD (as of mid-2026 from auros.global) or $1.3T+ cumulative (from homepage). Annual revenue listed on LinkedIn as $545K (likely outdated or incomplete – treat with caution).
- **Notable Investors/Partners**: $17M venture round in March 2023 led by Vivienne Court Trading. Prior Series A in 2019 with one investor. Partners include 40+ crypto exchanges/venues.
- **Growth Signals**: Headcount grew 53% YoY to 64 employees (LinkedIn); operates across 30+ geographies; team of 150+ claimed on homepage (may include contractors); active job postings for traders, engineers, and security roles.

## Competitive Advantages
- **Algorithmic precision and low-latency architecture** – built for high-frequency trading across all major crypto venues.
- **Partnership-based model** – unlike pure proprietary shops, they offer end-to-end liquidity solutions for token projects, creating sticky client relationships.
- **Global footprint** – 24/7/365 coverage with a decentralized workforce across 30+ geographies.
- **Resilient infrastructure** – emphasis on security, robustness, and reliability (Principal Security Engineer role posted).

## Strategic Focus

- **Institutional expansion** – growing OTC desk and services tailored for institutional market participants.
- **Engineering excellence** – continued investment in core systems, low-latency strategy development, and security.

## Why Work Here
- **Global-first culture**: Many roles are fully remote (with time‑zone alignment); hub offices in Hong Kong and New York for roles that require close collaboration.
- **High ownership, low ego**: Culture described as “high challenge, low ego” – engineers and traders own problems end-to-end and ship fast.
- **Complex, impactful work**: Problems sit at the intersection of trading, engineering, and token design, with real influence over digital market infrastructure.
- **Learning and growth**: Structured onboarding, regular feedback, opportunities to rotate across projects. Prior crypto experience not required for all roles – curiosity and problem-solving are valued more.
- **Transparent interview process**: Focuses on real capability (technical deep dives, practical problem-solving, scenario-based discussions) rather than “whiteboard theatrics.”
- **Perks**: Not detailed but implied autonomy, remote work setup, and regular in-person gatherings for remote teams.
