**职位描述**
你将从长篇自由文本文档中提取结构化事实，并确保每一个事实都与它来源的精确段落相关联。在这个平台上，任何断言都有可被人类审核员检查的引用，而这种可追溯性由你来构建和保护。
你将加入一个分析和 AI 工程团队，该团队构建了一个系统，可以接收来自数十个不同来源的记录，将其解析为正确的实体，并向人类审核员展示每个答案背后的确切源文本。在安全的政府云环境中运行，该平台依赖于可被验证的抽取，因为可以与原始文档进行比对。
你将加入一个已建立的抽取实践，而不是从零开始构建。该方法由团队中的高级从业者设定并定期审查。你的贡献是在大量、混乱、叙述性的文档上持续、稳定地输出结果，这些文档从未为抽取而撰写，并具备识别不符合要求的内容而非强行处理的判断力。
这是一个完全远程的职位，启动日期比我们最紧急的职位要晚。我们现在正在招聘，以便在工作开始时座位已满。
**主要职责**
- 从长篇自由文本、叙述性和半结构化文档中提取结构化事实
- 保持每个提取的事实与它来源的精确段落之间的可追溯指针
- 验证每个引用的段落确实支持提取的事实，将缺失或不支持的引用视为缺陷
- 区分财务叙述中的明示总数和推导总和，保留构成项和计算过程以供验证
- 使用提供给模型辅助抽取的记录规则上下文，将引用的事实和不确定性与任何有效性决策分开
- 一致地应用并扩展团队已有的抽取方法到新的文档类型
- 处理模糊、矛盾或不完整的源文本，而不强行得出结论

ABOUT DEFCON AI
RESILIENCE IN THE FACE OF DISRUPTION. DEFCON AI is an insights company that leverages artificial intelligence, mathematical optimization, data analytics, and software engineering for resilient optimization of complex systems.
In today’s dynamically changing world, DEFCON AI’s technology aligns outcomes with operational goals, better decision making, and empowers customers to anticipate assess, and mitigate the impacts of disruptions.
**About the Role**
You’ll pull structured facts out of long, free-text documents, and keep every one of them tied to the exact passage it came from. On this platform, nothing gets asserted without a citation a human reviewer can check, and that traceability is yours to build and protect.
You’ll join the analytics and AI engineering team behind a system that ingests records from dozens of disparate sources, resolves them to the right entity, and shows a human reviewer the exact source text behind every answer. Operating within a secure government cloud environment, the platform depends on extraction a reviewer can trust precisely because it can be checked against the original document.
You’ll join an established extraction practice rather than building one from scratch. The approach is set and reviewed by a senior practitioner on the team. Your contribution is sustained, consistent output at volume against long, messy, narrative documents that were never written with extraction in mind, and the judgment to flag what doesn’t fit rather than force it.
This is a fully remote role, with a later start date than our most urgent openings. We’re sourcing now so the seat is filled when the work begins.
**Key Responsibilities**
- Extract structured facts from long, free-text, narrative, and semi-structured documents
- Maintain a traceable pointer from every extracted fact back to the exact source passage it came from
- Validate that every cited passage actually supports the extracted fact, and treat a missing or unsupported citation as a defect
- Distinguish a stated total from a derived sum in financial narratives, retaining the contributing items and the calculation for verification
- Consume the recorded rule context supplied to model-assisted extraction, keeping cited facts and uncertainty separate from any validity decision
- Apply and extend the team’s established extraction approach consistently across new document types
- Handle ambiguous, contradictory, or incomplete source text without forcing a single reading; flag it rather than guessing
- Work with entity resolution and retrieval teammates on what a usable extracted fact needs to carry downstream
**Required Qualifications**
- 3+ years extracting structured facts or data from unstructured, narrative text in a production setting
- Experience keeping extracted output traceable to its source
- Strong Python, with hands-on NLP or information-extraction tooling, whether rule-based, statistical, or LLM-based
- US Citizenship Required
- Active US Secret clearance
**Preferred Qualifications**
- Extraction experience in a government, investigative, legal, financial-crime, or intelligence-adjacent setting
- LLM-based extraction with structured output schemas and validation against source text
- Experience where extracted facts fed a downstream matching, scoring, or retrieval system
- Active Top Secret clearance
**What Success Looks Like**
- Facts extracted at volume, with every claim traceable to its source passage
- Extraction that holds up when a subject-matter expert checks it against the original document
- Sustained throughput across new document types without re-deriving the approach for each one
**What We Offer**
- A fully remote, results-based environment
- Competitive salary, bonus, and equity package
- 100% employer paid, comprehensive health insurance including medical, dental, and vision for you and your family
- Unlimited PTO, with your manager’s approval
- Flexible work environment where you manage your work day
- 14 weeks of fully-paid parental leave
**Salary Range:** $130,000—$160,000. This represents the typical salary range for this position based on experience, skills, and other factors.
We’re an Equal Opportunity Employer: You’ll receive consideration for employment without regard to race, sex, color, religion, sexual orientation, gender identity, national origin, protected veteran status, or on the basis of disability.
