Security Advisor – Engineering & Product Security

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\’ll not 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.
