Who We Are

Intropic is a financial information and software company operating at the cutting edge of global capital markets.

Our clients include hedge funds, proprietary trading firms, index fund managers, large asset managers, sovereign wealth funds, and investment banks, who use our products to generate alpha, manage risk, and make better decisions in fast-moving markets.

Headquartered in London's Canary Wharf and expanding globally, we're a team that moves fast, takes real ownership, and holds itself to a high standard of rigour and integrity.

The Role

You will keep the day-to-day of Intropic's security and IT running, and build the systems that secure it further. Colleagues rely on the IT you run. Our SOC 2 relies on the evidence you keep clean. Where the work repeats, you build it away.

This role is built for someone with solid IT experience who wants to move into security. You already know how to run an estate: laptops, accounts, SaaS apps, and access paths. Here you'll put that knowledge to work on the security side, because you cannot write a good detection or a useful guardrail without knowing what normal looks like. The role is a mix of IT, security engineering, and GRC, and it is an engineering role throughout. Anything you find yourself doing twice by hand is a candidate for automation, and you will have the tools and the mandate to build it. As you grow, the security engineering side of the role grows with you.

This is a genuine route from IT into security engineering, at a company small enough that you will build things that matter from week one. It suits a fast learner who is excited by solving difficult problems.

Security Engineering - 40%

• Assist in engineering the security of our cloud infrastructure across AWS and GCP, from individual EC2 instances to a large EKS microservice estate.
