Senior Golang Engineer - AI & Platform Security

Location: UK (Remote-first)
Level: Senior/Principal/SVP-equivalent
Compensation: Highly competitive base + discretionary bonus

We are assisting with the hire for a Senior Golang Engineer to join a small, elite engineering team within a Tier 1 investment bank building production-grade AI platforms at scale.

This is a hands-on engineering role, suited to someone who enjoys building systems, actively attacking them, uncovering weaknesses, and redesigning them with security Embedded from day one.

The team operates independently with a startup mindset: modern tooling, minimal bureaucracy, and a strong bias toward shipping real products.

• Building secure, production AI platforms using Golang

• Actively breaking and stress-testing systems to identify vulnerabilities

• Conducting ethical hacking and attack simulations on real applications

• Securing AI-specific attack surfaces (eg prompt injection, model misuse, data leakage)

• Designing and building security tooling and frameworks

• Embedding security early while maintaining engineering velocity

• Setting engineering and security standards at a senior level

• Mentoring engineers on secure-by-design development practices

• Strong hands-on experience with Golang in production environments

• Background in application, product, or platform security

• Proven experience securing real systems, not just advising on them

• Ability to think like both a builder and an attacker

• Cloud-native experience (containers, Kubernetes, modern infrastructure)

• Interest in AI/GenAI/LLM security (commercial experience preferred, not essential)

No prior financial services experience is required.
Engineers from big tech, scale-ups, and high-growth startups are strongly encouraged to apply.

• This is not a compliance or governance role

• You'll be writing and shipping code, not policies

• Security is treated as a product and engineering problem, not a blocker

• High visibility, genuine autonomy, and long-term impact
