Job summary

PensarAI is seeking an Offensive Security Agent Engineer to build autonomous security capabilities for web applications and APIs in a cutting-edge platform. You will design harnesses, execution environments, and workflows enabling agents to discover and exploit vulnerabilities in real-world targets.

You will collaborate with security researchers, AI engineers, and product teams to turn offensive techniques into reliable, scalable autonomous capabilities.

Qualifications

• 4+ years of professional software or security engineering experience.
• Experience with web security concepts, browsers, APIs, and authentication mechanisms.
• Experience with agentic systems, LLM applications, or autonomous tooling is a plus.

Responsibilities

• Design and build the agent harness powering autonomous offensive security workflows across Apex and the Pensar platform.
• Build systems that allow agents to reliably interact with browsers, terminals, HTTP proxies, scanners, APIs, filesystems, and other security tooling.
• Develop orchestration for long-running, multi-step offensive security tasks involving reconnaissance, exploitation, validation, and reporting.
• Build abstractions that allow agents to safely and effectively execute tools, inspect results, maintain state, and adapt their approach.
• Improve agent context management, memory, task decomposition, planning, and execution across complex engagements.
• Design reliable execution environments for autonomous security agents operating against customer applications and infrastructure.
• Debug agent trajectories to understand why an agent succeeded, failed, or took an inefficient path.
• Build observability and debugging infrastructure for understanding agent behavior at scale.
• Enable agents to navigate and understand JavaScript-heavy applications, authenticated applications, APIs, and modern architectures.
• Translate manual offensive security techniques into primitives and workflows that autonomous agents can execute reliably.
