Security Advisor - Engineering & Product Security

A leading global trading firm is expanding its cybersecurity capability and is seeking a Security Advisor – Engineering & Product Security to bridge the gap between world-class software engineers and the security function.

You won't be spending your days writing exploits or performing hands-on code reviews. Instead, you'll act as a trusted partner to engineering teams, helping them make secure design decisions early and embedding security into the development lifecycle.

Responsibilities will include:

• Partner with development and infrastructure teams to identify security risks in design and architecture and guide them toward secure solutions.
• Consult with engineers building integrations (e.g., with platforms like Zoom or Bloomberg) to ensure these are designed securely from the ground up.
• Assess and threat-model third-party tools and services to ensure they don't introduce unnecessary risk.
• Translate complex security concepts into actionable advice that resonates with highly technical audiences.
• Act as a bridge between the offensive security mindset and secure engineering best practices.

What We're Looking For

• A strong technical foundation, ideally with a degree in Computer Science, Engineering, or a related field.
• Around 5–8 years' experience, including several years in a deep technical role (such as red teaming, penetration testing, or security research).
• Some recent experience in a consultative or advisory position, either within a consultancy or internal product security function.
• Technical credibility - you can hold your own in design and coding discussions even if you're not writing code every day.
• Broad knowledge of infrastructure, cloud, and application security, combined with an attacker's mindset.
• Excellent communication and influencing skills, able to build rapport with exceptional engineers and speak their language.
• Strong Linux knowledge and scripting experience; fluency in a programming language is a plus.

Why This Role?

• Collaborate directly with some of the best software engineers in the industry.
• Focus on solving real security problems at scale, not ticking boxes.
• Work in a high-performance, engineering-driven culture that values curiosity, creativity, and technical excellence.
• Be part of a team that prioritizes pragmatic, engineering-led security over compliance.

This is a highly visible, consultative role in which you'll influence how cutting-edge systems are built securely from the outset.
