Senior Golang Engineer - AI & Platform Security
Location: UK (Remote-first)
Level: Senior/Principal/SVP-equivalent
Compensation: Highly competitive base + discretionary bonus
The Opportunity
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.
What You'll Be Doing
* 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
What We're Looking For
* 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.
Why This Role Is Different
* 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
