We help organizations move AI out of experimentation and into production — safely, reliably, and at scale. From inconsistent performance to limited transparency and challenges with integration and long-term viability, our Applied Intelligence Engine solves the risks that cause most AI initiatives to stall.

Built for some of the most highly regulated industries in the world, we enable teams to deploy AI systems that are auditable, explainable, and aligned with real-world constraints. Our solutions introduce structure, visibility, and control into how AI operates, turning advanced capabilities into a dependable, production-grade infrastructure so our customers can move faster and scale with confidence.

Job Overview

You’ll help build Clearwing: an AI-native cybersecurity system for autonomous vulnerability discovery, exploit validation, pen-testing, reverse engineering, and security reporting. You’ll combine hands-on offensive security work with LLM agent development, eval design, and product engineering. The ideal candidate can chase real bugs, validate exploitability, write production-quality Python, and turn exploratory research into repeatable security capabilities.

Responsibilities

Develop AI-assisted vulnerability discovery workflows for source code, binaries, networks, and live systems.

Build and improve Clearwing’s source-code hunting, network pen-testing, N-day exploit, reverse engineering, and validation pipelines.

Design agentic workflows for reconnaissance, static analysis, dynamic testing, exploit development, patch validation, and reporting.

Perform static analysis to identify vulnerable patterns, reachable attack surfaces, and exploitability conditions.

Conduct authorized live testing against networks, services, containers, lab targets, and operational environments.

Develop and validate proof-of-concept exploits in controlled, authorized settings.

Build evaluation harnesses for vulnerability discovery quality, false positives, exploitability, reproducibility, and model/tool performance.

Improve safety, authorization, auditability, guardrails, and human-in-the-loop controls for dual-use cybersecurity capabilities.

Work with AI researchers and engineers to improve prompts, tools, agent loops, memory systems, scoring systems, and model-routing strategies.

Produce clear technical reports with evidence, reproduction steps, impact analysis, and remediation guidance.

Requirements

3+ years of hands-on cybersecurity experience in vulnerability research, penetration testing, exploit development, reverse engineering, or security engineering.

Practical experience with at least two of:

Static analysis

Dynamic analysis

Binary exploitation

Web application security

Network penetration testing

Cloud/container security

Malware analysis or reverse engineering

Detection engineering

Strong Python skills and comfort building automation around security tools

Familiarity with Linux, Docker, Kali/security tooling, Git, CI, and shell workflows

Ability to reason from vulnerability signal to exploitability, impact, evidence quality, and remediation

Experience working with LLMs, agents, prompt engineering, evals, or AI-assisted security workflows

Strong written communication skills for technical findings, customer-facing reports, and internal research notes

Clear judgment around authorization, responsible disclosure, and dual-use security tooling

Nice-to-haves

Experience with Ghidra, IDA, Binary Ninja, angr, Semgrep, CodeQL, Joern, AFL++, libFuzzer, ASan/UBSan, or OSS-Fuzz

Experience developing exploits for memory corruption, deserialization, auth bypass, SSRF, RCE, sandbox escape, or supply-chain vulnerabilities

Experience with CVE reproduction, N-day analysis, patch diffing, or exploit validation

Experience building LLM agents, tool-using systems, ReAct loops, eval harnesses, or synthetic-data pipelines

Familiarity with SARIF, CVSS, CWE, MITRE ATT&CK, MITRE CVE workflows, HackerOne/Bugcrowd-style disclosure, or government security reporting

Experience with Rust, Go, C/C++, or systems programming

Prior work with security products, autonomous agents, fuzzing infrastructure, or government/security customers

Benefits

Comprehensive benefits package, including health, dental, and vision insurance, as well as retirement savings plans

Opportunities for growth and professional development

A collaborative and supportive company culture that values diversity and inclusion

Access to cutting-edge technology and resources for research and development

Compensation (commensurate with experience): $180,000 - $200,000 (base salary) + equity
