Senior Cybersecurity Engineer – Offensive Security & VAPT

Overview

ABOUT NEXUSVOID
NexusVoid is building the world’s first Autonomous CISO – an AI-powered security operations platform with specialized agents for compliance, vulnerability scanning, red team operations, and threat intelligence. Supported by NVIDIA Inception Program and Razorpay Rize, we’re on a mission to automate the entire security lifecycle. Our next frontier: building autonomous red teaming agents that can conduct VAPT and offensive security operations with minimal human intervention.

ROLE OVERVIEW
We’re hiring a Senior Cybersecurity Engineer with deep expertise in Vulnerability Assessment and Penetration Testing (VAPT), red teaming, and offensive security. You’ll be the in-house security expert who not only conducts hands-on security assessments but also helps architect and train our AI-powered red teaming agents. Your real-world VAPT experience will directly shape how our autonomous agents discover, exploit, and report vulnerabilities.

KEY RESPONSIBILITIES

• Conduct end-to-end VAPT engagements: network penetration testing, web/API security assessments, mobile application testing, and cloud infrastructure reviews.
• Perform red team operations including adversary simulation, social engineering assessments, and assumed-breach scenarios.
• Document detailed attack methodologies, exploitation chains, and remediation recommendations in professional reports.
• Collaborate closely with the AI/ML team to translate manual VAPT workflows into automatable, agent-friendly processes.
• Design test cases, attack playbooks, and decision trees that autonomous red teaming agents can follow.
• Evaluate and integrate offensive security frameworks (Metasploit, Cobalt Strike, VIPER, Sliver, Caldera) into NexusVoid’s agent platform.
• Define vulnerability scoring, prioritization logic, and risk assessment frameworks for automated reporting.
• Stay current with CVEs, zero-day research, emerging attack vectors, and MITRE ATT&CK techniques.
• Mentor junior team members and build internal knowledge bases on offensive security techniques.

REQUIRED QUALIFICATIONS

• 4–8 years of hands-on experience in penetration testing, VAPT, or red team operations. Strong proficiency with offensive tools: Burp Suite, Nmap, Metasploit, Nessus/Qualys, Nuclei, SQLMap, Hashcat, Wireshark.
• Deep understanding of OWASP Top 10, SANS Top 25, CWE, and CVSS scoring.
• Experience with at least two of: network pentesting, web application testing, API security testing, cloud security (AWS/GCP/Azure).
• Proficiency in scripting/automation: Python, Bash, Go, or PowerShell for custom exploit development and tooling.
• Solid understanding of networking protocols (TCP/IP, DNS, HTTP/S), operating systems (Linux, Windows), and Active Directory.
• Ability to write clear, actionable penetration testing reports with executive summaries and technical details.

PREFERRED QUALIFICATIONS

• Industry certifications: OSCP, OSCE, CRTP, CRTO, CEH, GPEN, or equivalent.
• Experience with C2 frameworks: Cobalt Strike, Sliver, VIPER, Havoc, or Mythic.
• Familiarity with MITRE ATT&CK framework and adversary emulation tools (Caldera, Atomic Red Team).
• Background in reverse engineering, malware analysis, or exploit development.
• Experience with DevSecOps: CI/CD pipeline security, SAST/DAST integration, container security.
• Prior experience translating security workflows into automated or AI-driven systems.
• Bug bounty track record or published CVE research is a strong plus.

WHAT MAKES THIS ROLE UNIQUE
This isn’t a typical pentesting job. You’ll be the domain expert whose knowledge directly powers an AI agent. Every exploit you write, every attack path you document, every VAPT methodology you formalize – it all feeds into building an autonomous red teaming system. You’ll work at the intersection of offensive security and artificial intelligence, shaping a product that could redefine how organizations approach security testing.
