Security Engineering Manager - Crypto Custody & Trading

Job Description
I am hiring a Security Engineering Manager to build and lead a small, elite team protecting next- trading and crypto custody infrastructure. Reporting directly to the CTO, this is not a purely strategic or oversight role. You’ll be owning the security vision, building the roadmap, writing code, reviewing architecture, threat modelling, and automating at scale, while building a high-performance team around you.
This is what you will own:
Security Engineering Strategy
Define and execute the security vision across cloud infrastructure, applications, and detection systems, aligned to real-world risks, not checkbox compliance.
Team Leadership
Hire, mentor, and retain top-tier security engineers. Build a culture of technical excellence and trust.
Technical Execution
Design and implement secure-by-default patterns in AWS, Kubernetes, CI/CD pipelines, and crypto- systems.
Own IaC scanning, secrets detection, and automated control implementation.
Threat Modelling & Incident Readiness
Lead technical reviews of high-value trading and custody systems. Translate threat intel into proactive engineering solutions.
Cross-Functional Collaboration
Work closely with Engineering, DevOps, and Product teams to embed security from day one, not as a blocker, but as an enabler.
Please apply if you have done the following:
You’ve led security engineering teams but still write code and review complex systems personally
You’ve secured cloud-, high-availability, and/or low-latency trading systems
You’ve worked with or around crypto custody, DeFi protocols, or MPC wallets
You’re passionate about automation, infrastructure-as-code, and reducing manual security toil
You can clearly communicate risk to both engineers and senior stakeholders
As the Security Engineering Manager, you must be comfortable presenting security posture and roadmaps to executive leadership.
This role is hybrid out of London.
