Staff Security Detection & Response Engineer (AI-Driven Security Operations)

You will own how Workleap detects, investigates, and responds to threats across Workleap and ShareGate, and you will build the AI layer that runs it. Our security tooling generates more noise than a small team can handle, and too many findings are ambiguous or wrong. This role exists to turn detection and response into a system where agents triage, enrich, and investigate, and people make the calls that genuinely need judgment.

Your impact:

• Build the pipeline that runs security operations end to end: integrations that pull alerts and findings out of every source tool, an agentic system that triages, enriches, correlates, and drafts investigations, and a connection into Jira that routes each result to the owning team with evidence and a fix path, so no finding is ever copied by hand.
• Define the trust model for those agents, deciding what they close alone, what they recommend, and what always goes to a human, backed by evaluations and secured against prompt injection and permission abuse.
• Drive false positives and misrated findings out of our security tooling, so every finding that reaches a person is real and correctly prioritized.
• Own detection engineering end to end, written as code and mapped to MITRE ATT&CK, so coverage survives any change of platform.
• Lead security incident response from triage to postmortem, with agents gathering evidence, and hold our managed detection partner to a measurable standard.
• Make security a partner developers want to work with, delivering findings in their workflow with clear evidence and a fix path.

Your Team

Over the next 12 months, LeapSec is delivering two strategic bets: putting security inside product squads, with agents carrying vulnerability and detection work, and automating SOC 2 evidence so nobody gathers it by hand. You will own the detection and response side of that work: cleaning up the tooling, building the agents, and proving how much they can be trusted to do alone.

LeapSec covers Security Operations and Compliance across Workleap and ShareGate. You will report to the Director of Infrastructure and Security and work daily with our Staff Application Security Specialist and security tooling team, and as needed with Infrastructure, ITX, and product engineering. We are a small team with a wide mandate: we track work honestly in Jira, deliver on fixed dates, and expect people to own outcomes end to end.

Our environment is Azure-first, with a cloud-native SIEM and XDR stack, Zscaler, Cloudflare, and a managed detection partner today. We choose tools on merit and expect to keep choosing.

What You’ll Bring

• 7+ years in security operations, incident response, or detection engineering, with recent hands-on time in a cloud SaaS environment.
• Deep experience working with findings that are not clean: validating what tooling flags, tuning false positives out at the source, and deciding with incomplete evidence whether something is real.
• Years of working directly with developers, getting fixes shipped without authority and keeping the relationship intact when the answer is no.
• Built and shipped agent systems for security work that others depend on, such as MCP servers, Claude skills, subagents, or custom tools, with evaluations that decide when the output is trusted.
• A working model of how agentic systems fail and get attacked, including prompt injection, tool permission scoping, and credential handling.
• Detection engineering as a discipline: detections as code, a SIEM query language you write fluently, and false positive rates you actually measure.
• Strong grasp of identity and cloud attack paths, ideally in Azure and Entra ID.
• Bonus: experience directing a managed detection partner, threat hunting, or forensics, and working proficiency in French.
