Responsibilities
- Design, develop, maintain, test, deploy, and sustain AI-enabled software and research tooling for computer network exploitation and vulnerability research.
- Own complex features and subsystems from requirements refinement through implementation, deployment, and ongoing sustainment.
- Develop agentic AI harnesses that orchestrate research tools, manage execution state, collect evidence, and evaluate results.
- Build sandbox-based dynamic analysis capabilities for executing and observing software, capturing runtime behavior, and reproducing vulnerabilities.
- Integrate debugging, instrumentation, fuzzing, crash analysis, and related research tools into automated or researcher-directed workflows.
- Create repeatable evaluations measuring finding validity, reproducibility, false-positive rates, and the usefulness of AI-assisted analysis.
- Develop backend services, APIs, data pipelines, and user interfaces that make research capabilities accessible and results traceable.
- Troubleshoot complex issues across application code, AI integrations, research tooling, and execution environments while improving performance, reliability, and observability.
- Lead design and code reviews, document technical decisions, mentor engineers, and communicate progress, risks, and tradeoffs to stakeholders.
Requirements
- At least 12 years of experience and a TS/SCI clearance with polygraph; a B.S. in a technical discipline or 4 additional years in place of the B.S.
- Demonstrated ability to independently design, implement, test, and deliver complex software features or subsystems.
- Proficiency in Python and maintainable, tested software development using modular design and object-oriented programming practices.
- Expertise in AI-enabled computer network exploitation or vulnerability research, including integrating AI into research workflows and evaluating outputs.
- Experience with vulnerability research or software analysis techniques such as reverse engineering, debugging, dynamic analysis, fuzzing, or crash triage.
- Working knowledge of isolated execution environments, runtime instrumentation, execution tracing, environment reproducibility, and evidence collection.
- Experience developing LLM applications or agentic systems with external tools, structured outputs, workflow state, error handling, and evaluation.
- Experience developing backend services and REST APIs using FastAPI, Flask, or Django and working with relational databases such as PostgreSQL.
- Experience working in Linux environments and understanding operating system behavior, processes, memory, and networking relevant to software analysis.
- Experience using Git, automated testing, CI/CD, and code review in collaborative software delivery.
- Ability to translate ambiguous requirements into technical work, explain tradeoffs, and guide other engineers.
- Preferred experience includes dynamic vulnerability research in sandbox environments, AI agents interacting with debuggers or fuzzers, virtualization, emulation, snapshots, automated provisioning, C/C++, assembly, binary analysis, memory corruption analysis, operating system internals, AI evaluation datasets, retrieval-augmented generation, vector databases, Elasticsearch, Qdrant, ChromaDB, TypeScript, React, security tooling, open-source projects, or technical publications.
Benefits
