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
