Lead Threat Intelligence Engineer

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 looking to build a dedicated threat intelligence capability. Today, adversary tracking, fraud pattern analysis, and abuse intelligence happen informally across a few teams. This role makes threat intelligence a standing discipline: characterize who is targeting Clio and organizations like it, what they're using, and turn that into work other teams can act on.

This is a senior individual-contributor role, where you'll be expected to establish and formalize how Clio tracks adversaries. This is the first hire in a function Clio intends to grow — the practices you establish become the foundation the rest of the team is built on.

You will work closely with Clio's internal red team and detection engineer. Threat Intelligence characterizes the adversary — who they are, how they operate, what to watch for. The Red Team takes your prioritized, evidence-backed picture of the threat and decides what to simulate and attack; the detection engineer turns the same picture into detection logic in our SIEM. As the detection platform matures, your intelligence requirements shape what gets built.

What We're Protecting Firms From

Clio has nearly every piece of data you can conceive: privileged litigation strategy, M&A documents, and trust accounts that can get a lawyer disbarred if they're not protected properly! The Panama Papers breach showed the stakes — 11.5 million client documents left Mossack Fonseca, and the firm shut down two years later. The legal field is rife with examples where security must be taken seriously:

• •Silent Ransom Group (Luna Moth) has extorted more than 100 US law firms since 2023, using IT-themed vishing calls and, recently, operatives who walk into firm offices posing as IT technicians (FBI advisories, 2025 and 2026)
• •INC Ransom claimed 20 legal-sector victims in 2026, ten of them inside a single 48-hour window
• •Chinese state actors breached Williams & Connolly and Wiley Rein to reach trade, sanctions, and M&A matters; Mandiant estimates 80 of the 100 largest US firms have been hacked since 2011

Most of Clio's customers are solo, small, and mid-size firms — the segment with the highest breach rate (ABA 2025 data) and the least in-house security. At the same time some of the largest legal organizations, including governments, rely on Clio. When you characterize an adversary, you protect tens of thousands of firms that cannot do this work themselves!

AI Is the Expectation:

Clio's security team works with AI every day, and this role is built on that assumption. You'll use AI agents to scale collection, enrichment, triage, and first-draft reporting — and apply your own judgment to everything they produce. The adversary side is part of your beat too: AI-enabled tradecraft belongs in the landscape you cover. If the idea of directing a fleet of agents sounds like how intelligence work should be done, you'll fit perfectly at Clio.

A Day in the Life

• •Digging through raw infrastructure data to attribute a phishing kit to a known actor before any vendor report names them
• •Briefing security leadership team on a geopolitical or sector-specific threat trend relevant to legal tech
• •Writing fraud pattern briefs from account-abuse signals and handing the Trust (anti-abuse) function specific patterns to detect
• •Working with our payment operations group to identify fraud patterns and rings within Clio Payments
• •Mentoring newer analysts on how to separate a credible early indicator from noise
• •Proposing a new data source or tracking method because the current one is missing a class of activity

What You'll Do

Building the program

• •Define and maintain Clio's Priority Intelligence Requirements with stakeholders across Security, Trust, Payments, and leadership, then run the full intelligence lifecycle against them — from requirements through dissemination and feedback
• •Stand up Clio's threat intelligence platform and make it the system of record for tracked actors, campaigns, and indicators
• •Shape vendor purchases and tooling rollouts — OSINT and dark-web monitoring, feeds, enrichment — as the program's collection needs take form
• •Measure whether intelligence changes outcomes: detection coverage in the SIEM (Splunk, ELK/OpenSearch), Red Team campaign success grounded in your reporting, and time-to-detect on incidents with prior intel coverage

Intelligence production

• •Track external threat actors, techniques, and infrastructure relevant to legal tech and Clio's customer base
• •Produce intelligence at three tiers: tactical indicators and TTPs for detection, operational campaign briefs for security leadership, and strategic landscape assessments for executives
• •Establish and refine Clio's methodology for tracking adversary campaigns, rather than running someone else's playbook
• •Produce original research: infrastructure hunting from raw data, malware and campaign attribution
• •Analyze fraud and abuse patterns and insider-threat signals, and turn them into briefs the Trust (anti-abuse) function can act on
• •Track BEC and trust-account wire-fraud tradecraft targeting law firms, and feed it into fraud detection for Clio Payments
• •Assess coordinated disclosure and patch-storm events for real exploitation urgency

Feeding other teams

• •Hand Red Team a prioritized, evidence-backed list of techniques worth simulating
• •Hand our detection engineer intel-backed detection requirements
• •Brief security leadership directly, in addition to the SOC and engineering teams
• •Alert Payment Operations of external signals: tracked actors, fraud rings, known malicious domains/IPs, etc. to filter fraud from our payments business before they can act

External relationships

• •Manage commercial threat-intel feed vendors and evaluate new ones against cost and signal quality
• •Participate in industry intel-sharing groups and represent Clio in those relationships
• •Collaborate and code with the blue team on defensive remediations

What You Bring

• •5+ years in threat intelligence or a closely adjacent function, with original research you can point to
• •Experience establishing or scaling a security function/team from the ground up, not just operating inside an existing one. Self-starter.
• •Scripting ability (Ruby, Python, or similar) for building, upgrading, and maintaining automation
• •Fluency with MITRE ATT&CK, the Diamond Model, and structured analytic techniques such as Analysis of Competing Hypotheses, applied in your own analysis
• •Track record of establishing or materially improving a tracking methodology someone else now uses
• •Comfort briefing both technical teams and director+ level, and adjusting the message for each
• •Ability to turn raw intelligence into a specific, actionable ask for another team — a detection to write, a technique to simulate, a vendor risk to flag
• •Fluency with AI tooling in analytical work — agents for collection, enrichment, and drafting — and the judgment to validate what they produce
• •Experience mentoring more junior analysts

Bonus Points

• •Existing relationships in industry intel-sharing communities
• •Experience with fraud or insider-threat analysis in addition to external threat tracking, or financial services cybercrime experience
• •Familiarity with the legal-tech or professional-services threat landscape, or ability to build that context quickly
