About VulSight

Location : Islamabad, Pakistan — on-site, full-time

Team : Engineering (AI / Research)

Start : ASAP

VulSight is a Web3 security firm helping teams ship safely across Move, Rust, and EVM ecosystems. We’ve delivered hundreds of assessments in traditional cybersecurity and Web3, and we’re now building NLP / LLM-driven agents that reason over code, audits, and on-chain data to catch bugs earlier and accelerate reviews.

The Role

You’ll own our AI roadmap end-to-end— research → prototyping → productization → team leadership . Your focus is on LLMs, NLP, and AI agents (tool use, planning, retrieval, evaluation) grounded in solid ML fundamentals . Blockchain / security knowledge is a plus.

What you’ll do

• Design & ship agentic systems that reason over smart-contract code (Move / Solidity), diffs, on-chain data, and prior audits; perform retrieval, analysis, test generation, and triage.
• Build RAG pipelines (indexing, chunking, retrievers), long-context strategies, tool calling, and multi-step planning (e.g., LangGraph-style flows).
• Own LLM evaluation : golden sets, style metrics, rubric-based grading, and production feedback loops (hallucination detection, safety, guardrails).
• Lead prompt engineering and model customization (SFT, LoRA / QLoRA, instruction tuning, RLAIF / RLHF where appropriate).
• Stand up inference infrastructure (vLLM / TGI / Triton), latency & cost optimization, caching, and observability (tracing, telemetry, error budgets).
• Curate high-quality datasets from public repos, audits, and on-chain sources; build labeling and synthetic-data pipelines.
• Collaborate with security researchers to turn workflows into auditor-grade copilots (invariant mining, property / test generation, patch suggestions).
• Hire, mentor, and lead a small on-site AI team; drive roadmap, rituals, and delivery quality.
