Staff Software Engineer, Data & AI

Holly • New York, NY

11h • $202,000 - $262,000 • Onsite

About The Position

We're hiring a Staff Software Engineer, Data & AI to own the technical direction of Holly's Data Platform. Local governments publish enormous amounts of public information salary schedules, job classifications, MOUs (Labor Union Agreements), budgets but it's scattered across thousands of websites and buried in messy formats: scanned PDFs, inconsistent HTML, spreadsheets, and everything in between. Turning that chaos into clean, searchable, trustworthy data is one of our biggest product challenges and deepest moats.
You'll set direction for the Data Platform: ingestion and processing pipelines, canonical datasets, semantic search and retrieval, and inference APIs that product teams build on. AI is part of the infrastructure, not a layer added later. You'll establish how Holly uses models for extraction, classification, normalization, matching, and search, and how we evaluate and operate those systems in production.
This is a hands-on Staff role with domain-wide scope. You'll set direction across ingestion, processing, modeling, search, inference, quality, and product consumption; resolve architecture decisions that span teams; and make other engineers more effective on the platform. You'll work directly with the founders and partner across Product and Engineering to decide which Data Platform investments matter most.
If you've worked with large, high-volume data and love the challenge of taming messy real-world inputs into something people can rely on, we'd love to talk.

Requirements

• Have 8+ years building and shipping production software, or equivalent experience, including sustained Staff-level scope across a Data or AI Platform.
• Have led the architecture and operation of production data systems used by multiple teams.
• Have worked with large-scale, high-volume data ideally where lots of sources, users, or records make volume and reliability matter.
• Are strong at data modeling and SQL, with experience designing schemas that others build on (Postgres a plus).
• Have built and owned ETL/ELT pipelines that handle messy, heterogeneous, real-world inputs (scraped data, PDFs, HTML, spreadsheets).
• Have led production search, retrieval, inference, or AI-assisted data-processing systems.
• Know how to evaluate model quality and operate model-backed systems when outputs are probabilistic.
• Bring a strong data-quality mindset validation, testing, monitoring, lineage, and reliability are core to how you work.
• Turn ambiguous company problems into technical direction, sequenced work, and clear ownership.
• Make other engineers better through architecture, mentorship, and reusable standards.
• Are pragmatic about tooling and comfortable working in (or ramping quickly into) a modern TypeScript/Postgres codebase.
• Candidates must reside in New York or be able to commute to our NYC office.
• Applicants must be authorized to work in the U.S. without requiring sponsorship.

Nice To Haves

• Open source contributions to or maintainer of a widely used tool.
• Experience with large-scale web scraping / crawling, document extraction (OCR), or LLM-assisted parsing.
• Experience with embeddings / vector search or supporting ML/AI data workflows.
• Experience with analytical/columnar or warehouse stacks (ClickHouse, BigQuery, Snowflake) and/or streaming pipelines.
• Experience in government, public sector, or civic tech.
• Prior early-stage startup experience.

Responsibilities

• Own the technical health of Holly's Data Platform, lead cross-team decisions, and build the data and AI systems and standards the rest of the product depends on.
• Own and Build the Data Platform end-to-end from raw public sources to clean, canonical datasets the product consumes.
• Design the architecture, schemas, and standards for how Holly ingests, models, and trusts its data.
• Partner with the founders to identify, scope, and de-risk our highest-leverage data initiatives.
• Set technical direction for the data domain across teams.
• Build systems that collect large volumes of public government data from thousands of local-government sources across the web.
• Turn messy, heterogeneous inputs scanned PDFs, inconsistent HTML, spreadsheets into structured, normalized data (parsing, extraction, OCR, dedupe, entity resolution, schema mapping).
• Where it adds leverage, incorporate LLM-assisted extraction and embeddings into the pipeline.
• Build for freshness, reliability, and scale so data stays current and trustworthy.
• Design canonical data models and domain schemas that product engineers build on.
• Expose clean, versioned, well-documented datasets the main app can reliably consume.
• Own data quality, validation, lineage, and observability so downstream teams can trust what they're building on.
• Set the architecture for semantic search and retrieval over large, changing government datasets.
• Design inference APIs for extraction, classification, matching, and other AI-powered data processing.
• Establish evals, tracing, fallbacks, and cost controls for model-backed systems.
• Create reusable interfaces that let product teams ship Data & AI capabilities safely.
• Evolve pipelines from manual/one-off toward automated, self-healing, monitored systems.
• Establish data-quality checks, alerting, and standards that keep the platform reliable as it grows.
• Establish patterns other engineers can use to collect, validate, and serve data safely.
• Lead cross-team architecture work and make the system easier for others to extend.

Benefits

• Domain ownership.
• Cross-team influence.
• Commitment to Open Source. We are big believers in supporting open source, and provide a monthly day of Open Source where you can work on your favorite tool. In addition to internal hackathons and other projects.
• Direct access. Work directly with the founders, with autonomy to drive major initiatives end-to-end.
• High-impact scope. Build the data foundation the entire product depends on, and see its power features customers rely on quickly.
• Public-service impact. Your work improves how local governments operate, helping millions of Americans access public-service careers.
• Competitive package. $202k-$262k base, 0.25-0.60% equity (L4), comprehensive health benefits (platinum plan with vision and dental), 401(k), paid parental leave, and a professional development stipend.
