Senior Golang Security Engineer - GenAI

A global financial services organisation is building a flagship Generative AI engineering team, responsible for designing and securing large-scale AI products and platforms used across the business.

This is a rare opportunity to join a cutting-edge, product-led GenAI team that operates independently from traditional corporate bureaucracy. The team is built in the style of a modern big-tech engineering organisation, with a strong focus on autonomy, engineering quality, and real-world impact.

The Role

We're looking for a Senior Golang Security Engineer (SVP level) with a strong cyber security background and an offensive, hacker mindset.

This role is fundamentally about breaking things to make them better:

• Hacking real GenAI products and platforms
• Finding weaknesses, exploiting them, and understanding true risk
• Designing and implementing practical, production-ready security improvements

This is a hands-on coding role for builders-not theorists.

What You'll Be Doing

• Actively attack and stress-test GenAI applications and platforms to identify vulnerabilities
• Build and secure production-grade GenAI systems, primarily using Golang
• Identify and mitigate LLM-specific risks, including prompt injection, misuse, and emerging AI threat vectors
• Develop security tooling, automation, and guardrails that integrate directly into engineering workflows
• Partner closely with engineers to embed security without slowing delivery
• Lead by example through coding, pairing, and setting high engineering standards

What We're Looking For

We're seeking someone who has secured real-world products and isn't afraid to get deep into the code.

You'll likely have:

• Strong Golang engineering experience in production environments
• A background in cyber security, product security, or offensive security
• Hands-on experience finding, exploiting, and fixing vulnerabilities
• A builder's mindset - you code as confidently as you hack
• Experience working in modern, product-driven engineering teams (eg big tech, high-growth tech companies, or similar)

Nice to have (but not essential):

• Experience with GenAI/LLM-based systems
• Cloud-native and Kubernetes security exposure
• Security tooling, automation, or red team experience

Banking or financial services experience is not required.

Seniority & Impact

This is a senior, SVP-level role with real influence:

• You'll help define security standards and best practices for GenAI across the organisation
• Act as a technical authority for secure AI engineering
• Opportunities to engage with senior leadership and influence strategy (if desired)
• No mandatory people management - leadership through expertise is key

Working Model & Benefits

• Remote-first (UK-based)
• Office attendance once a month
• Competitive senior-level compensation
• Annual performance-related bonus
• 27 days annual leave (plus bank holidays)
• Private medical cover, life insurance, pension, paid parental leave
