Software Development Manager - Application Security in London

Clio is the global leader in legal AI technology, empowering legal professionals and law firms of every size to work smarter, faster, and more securely.
We are transforming the legal experience for all by bettering the lives of legal professionals while increasing access to justice.
Summary:
The Role
Clio is building an agentic Security Operations Center. Instead of staffing a room of analysts to watch dashboards, we're building the AI-driven system that does the watching: it triages alerts, investigates, and takes the first response action, so the humans on the team spend their time on the work that needs a human. Our goal is to automate every event we can, and we mean every event. We're looking for the manager who builds both the Blue Team's software and the team itself. This is an engineering leadership role first. The team writes software: detection pipelines, automated response, the agents, and the integrations that tie them into Clio's products and infrastructure. You'll lead that team, set its technical direction, and stay close enough to the code to review it and contribute. Beyond leading, you'll get into the codebase and make changes in the agentic SOC and Clio's core applications, accelerated by Claude and Codex. You won't be working alone. Clio's Red Team finds and exploits weaknesses; the Threat Intelligence function tracks who is targeting us and how. The Blue Team takes what both of them learn and turns it into defenses that hold: hardened infrastructure, hardened product, and detection that catches the next attempt automatically.
Building the Team
As you onboard, one of the first tasks will be building out the team. We care much more about finding the right people than filling seats quickly, and you'll own that search: defining what great looks like, interviewing, and selling the work to people who have plenty of options.
The people we want are builders who are curious about security, or security people who build. You'll set the culture for a small, senior-leaning team that ships, owns the results, and makes its work visible to the rest of the company.
