Hiring for SecurITe — via Flexiple, the recruiting partner on this role.

About the Company
SecurITe builds AI-powered, healthcare-native cybersecurity to protect patient data and critical systems. We combine security research and engineering to help defenders understand threats and protect the infrastructure that supports patient care.

About the Role
You will help build an agentic-AI driven cybersecurity platform by translating vulnerability research into practical network defenses. This is a hands-on research and detection-engineering role for someone with 3+ years of experience, including 2–3 years working directly with Suricata. What you’ll do
- Reverse engineer software and root-cause known or novel vulnerabilities across operating systems, enterprise applications and network devices.
- Write, test and optimize custom Suricata IDS/IPS signatures, using accurate payload matching and buffer keywords.
- Inspect PCAPs with Wireshark to investigate protocol anomalies and minimize false positives.
- Build or analyze exploit proof-of-concepts safely in controlled labs and translate attacker behavior into detection tests.
- Tune signature performance for high-throughput network monitoring environments.
- Collaborate with data scientists on AI/ML approaches to zero-day detection; prior model-building experience is not required.




- Write technical briefs, coordinate responsible vendor disclosures and work with engineering and threat-intelligence teams. What you bring
- At least 3 years of relevant experience, including 2–3 years of hands-on Suricata rule development; deploying existing rules alone is not enough.
- Experience authoring robust Suricata syntax, payload matches and buffer keywords, and tuning detection performance.
- Reverse-engineering proficiency with IDA Pro, Ghidra or x64dbg, including root-cause analysis of vulnerabilities.
- Deep understanding of TCP/IP, HTTP/2, TLS, DNS and SMB, plus memory corruption, remote code execution and injection flaws.
- Strong Python, C, C++ or Lua skills for analysis, automation and log parsing.
- Deep familiarity with Linux/Unix internals, network monitoring and PCAP analysis.
- Ability to independently verify exploit behavior safely and communicate actionable findings. Nice to have
- Novel vulnerability discoveries, public CVE credits or vendor hall-of-fame recognition.
- Technical blogs, whitepapers or detailed exploit root-cause reports.
- Open-source signatures, GitHub security projects or conference presentations.
- Experience with Snort or YARA alongside required Suricata expertise. Originally posted on: 11 Nov 2026
