Senior Software Engineer — Data Platform

Nasdaq’s Data Platform turns messy, multi‑modal content into trusted, governed data that powers decisions and AI experiences across the company. As a Software Engineer, you’ll design and scale workflows that acquire content from heterogeneous sources, extract structured knowledge, and assemble golden records with full lineage and governance. You’ll build multi‑agent workflows and digital workers that automate onboarding, transformation, and quality checks—so the right data is accurate, explainable, and on time. You’ll join a tight‑knit engineering group where you own meaningful slices of the platform, collaborate closely with product and data partners, and see your work land in production. What you’ll build & own Acquire — Design and implement pluggable connectors (APIs, S3/Blob, SFTP, HTTP, message buses). Ship auth, throttling/backoff, CDC, idempotent loaders, and safe backfills with dashboards and alerts. Extract — Build layout‑aware parsing for PDFs/HTML/DOCX/Images with OCR; segment content for RAG and entity matching; enrich topics, language, and license flags with measurable precision/recall. Match — Implement and evaluate entity‑resolution pipelines (Siamese/bi‑encoders rules); define blocking keys; add transparent match explanations for stewards and audit. Map — Contribute to an LLM‑assisted “suggest → approve → apply” field‑mapping flow; run change‑impact checks; extend transformation libraries (dates, currencies, code mappings) with tests and versioning. Master — Assemble golden records with survivorship rules; maintain SCD2 history; enforce constraints, anomaly detection, and freshness SLOs. Qualifications Required 3 years in software/data engineering (or equivalent), with production experience building and operating data pipelines or AI‑enabled data services. Proficiency in Python and SQL; working comfort with Bash and Linux tooling. Demonstrated ability in containerization (Docker), Git CICD pipelines, and AWS services (S3, EC2, ECS, EKS). Hands‑on with at least one of: Spark/Databricks (or similar distributed compute), orchestration, Kafka (or event/stream tech). Ability to write clear design docs, run experiments, interpret metrics, and make trade‑offs (speed vs. reliability vs. cost). Nice to have Experience building agentic and multi‑agent workflows (tool routing, skill specialization, evaluation/guardrails). Familiarity with LLM‑powered enrichment (prompting, RAG, embeddings), vector stores, and quality evaluation for extraction/matching. Exposure to Databricks, Delta/Unity Catalog, data lineage, and data governance.
