Job summary

Supernova Technology is seeking a highly skilled Senior Security Engineer to protect our fintech platform and enterprise environment. You will lead threat hunts, build detections, and own security tooling across AWS, Windows, Linux, containers, and SaaS.

You will collaborate with engineering and IT to strengthen controls, respond to incidents, and mentor junior staff while aligning with NIST, ISO 27001, SOC 2, and regulatory requirements.

Qualifications

• 5+ years in security engineering, threat hunting, detection engineering, security operations, incident response, or infrastructure security.
• Proven ability to independently lead complex technical projects end-to-end.
• Hands-on experience with enterprise security platforms (SIEM, EDR/XDR, firewalls, IDS/IPS, WAF, vuln management, email/identity security) and threat hunting across varied telemetry.
• Strong knowledge of attacker TTPs, IR processes, and MITRE ATT&CK.
• Solid grasp of network security fundamentals (segmentation, firewalls, VPNs, DNS, HTTP/TLS, access control).
• Scripting/automation ability (Python, PowerShell, Bash, REST APIs).
• Strong analytical skills with incomplete/ambiguous information, and excellent communication with technical and non-technical audiences.
• High integrity and discretion with privileged systems and sensitive investigations.
• Fintech, financial services, or other regulated tech experience preferred.
• Familiarity with tools like CrowdStrike, Microsoft Defender, Splunk, Rapid7, Palo Alto, Fortinet, Cisco, or Cloudflare preferred.
• AWS security services, cloud‑native detection, and Docker/ECS or comparable container‑security experience preferred.
• Digital forensics, malware analysis, or offensive security experience preferred.
• SOAR/detection-as-code pipeline experience preferred.
• Threat intel platforms and OSINT techniques preferred.
• Relevant degree or certifications (CISSP, GCIH, GCIA, GCFA, GNFA, OSCP, CCSP, AWS Security Specialty, etc.) preferred.

Responsibilities

• Run hypothesis-driven and intelligence-led threat hunts across endpoint, network, identity, cloud, email, application, and SaaS telemetry, analyzing large datasets to surface suspicious behavior, control gaps, and emerging attack techniques.
• Turn threat intel and adversary TTPs into hunt hypotheses and detection logic; build and tune SIEM queries, correlation rules, dashboards, and alerts aligned to MITRE ATT&CK.
• Convert hunt findings and incident lessons into durable detections, prevention controls, and playbooks; continuously evaluate detection coverage, false-positive rates, and telemetry quality.
• Track emerging threats relevant to financial services, cloud, and software supply chains.
