Description

  • Own the architecture and evolution of the large-scale data extraction and normalization platform.
  • Design systems that process hundreds of thousands of records from heterogeneous sources including PDF, HTML, APIs, and spreadsheets.
  • Reduce human-in-the-loop validation by implementing AI-based validation, confidence scoring, provenance tracking, and deterministic safeguards.
  • Establish system contracts for correctness, traceability, and confidence.
  • Balance AI-driven approaches with procedural and rules-based systems to improve reliability and explainability.
  • Identify and remediate architectural and operational bottlenecks affecting scale, accuracy, and developer velocity.
  • Serve as the technical authority on critical system design decisions, including blocking poor designs and introducing new tooling or platforms when needed.
  • Partner with product teams and downstream consumers to define quality bars, SLAs, and success metrics.
  • Act as a technical escalation point for production issues, reliability failures, and systemic risks.
  • Mentor senior engineers, shape technical culture, and contribute hands-on to long-term technical strategy.

Requirements

  • 15+ years of experience building and operating large-scale production systems.
  • Proven experience designing data ingestion, extraction, or processing systems at scale.

  • Demonstrated ability to design trustworthy systems that combine probabilistic AI and deterministic approaches.
  • Strong understanding of system reliability, observability, failure modes, and iterative hardening.
  • Experience reducing operational or human overhead through better system design.
  • Track record of technical leadership across teams without formal people management.
  • Comfort operating in ambiguity and driving clarity where none exists.
  • Passion for using AI responsibly and effectively to deliver scalable, high-confidence systems.
  • Experience with document understanding, NLP, or financial data extraction is preferred.
  • Experience building provenance, lineage, or confidence-scoring systems is preferred.
  • Familiarity with cloud-native architectures and modern data stacks is preferred.
  • Experience shaping or owning internal platforms used by multiple teams is preferred.

Benefits
