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 (e.g., 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
McGregor Boyall is an equal opportunity employer and do not discriminate on any grounds.
