About Numeral:
Numeral is transforming how taxes get done. Digital businesses are currently bogged down by a painful web of regulations across 47 states and 70+ countries. We're eliminating this burden so teams can focus on their core mission.
We're the largest and fastest-growing AI-native tax solution. Started in 2023, Numeral has raised over $57M from Benchmark, Mayfield, Y-Combinator, and many others. We now serve over 3,000 paying customers and have more than tripled our revenue every year in our history.
What you'll do:
  • Reconcile financial and transactional data from multiple sources to enable accurate, repeatable sales tax filings
  • Normalize customer data across platforms (e.g. Stripe, Shopify, Numeral API) to ensure integrity in tax workflows
  • Partner with Sales, Engineering, Product, and Solutions teams to troubleshoot and resolve onboarding data issues
  • Support our customer-facing teams with ad hoc data questions, investigations, and insights
  • Build internal tooling and processes to streamline reconciliation and improve onboarding throughput
  • Improve the fidelity and performance of our DBT pipelines and help evolve our broader data architecture
What you'll bring:
  • Proficient in SQL and Excel / Google Sheets
  • Strong analytical and pattern recognition skills across large, messy, or multi-source datasets
  • Experience reconciling financial or transactional data (ideally in an e-commerce or payments environment)
  • Strong problem-solving skills and ability to operate with autonomy in fast-moving environments
  • Clear communicator with high attention to detail and a collaborative mindset
  • Startup mindset: Not scared of ambiguity and hungry for rapid growth
  • Intensity & Ownership: This is not a 9-5 - we're scaling rapidly and have a massive opportunity ahead of us.
  • Customer Obsession: You deeply care about the user experience and solving their problems
Even better:
  • Experience with DBT or similar ETL frameworks
  • Familiarity with Stripe, Shopify, Fivetran, Parquet, S3, DuckDB
  • Comfort navigating REST APIs and programmatically transforming data (e.g. Python or other scripting languages)
  • Prior exposure to tax, compliance, or accounting-related data
  • A background in operations, finance, or technical customer success
What we offer:
  • Competitive salary and equity - you'll share directly in the company's success
  • Full medical, dental, and vision coverage
  • Wellness perks like Headspace and the Peloton One App
  • 401(k) to help you build long-term financial security
  • Lunch and snacks when you're in the office
