Description

Neo.Tax automates R&D tax credits and software cost capitalization for enterprises. We ingest data from project management, payroll, identity, and financial systems and use ML/LLMs to turn a process that used to take months into one that takes hours. Small team, real revenue, lots of hard problems in data extraction and pipelines at scale. Currently serving customers like Mercury, Brex, Notion, Adobe, and Capital One. We're hiring two senior roles: (1) Senior Full-Stack Software Engineer (7+ yrs): TypeScript/Node + React; data ingestion pipelines processing millions of records and flexible schemas; own projects end-to-end, scope with cross-functional partners, ship customer-facing and internal tooling. Bonus: GraphQL, GCP/AWS/Azure, Terraform/DevOps. (2) Senior Data Scientist + ML Engineer (6+ yrs): Own ML/AI problems from definition through production: classification, information extraction, entity resolution, ranking, anomaly detection, plus LLM systems (prompts, retrieval, tool-calling, eval). Python (NumPy/Pandas/sklearn/PyTorch), strong SQL, and real production deployment experience. Bonus: synthetic data, RAG, experience fine-tuning LLMs. Both are senior, high-autonomy roles—comfortable breaking ambiguous requirements into iterative deliverables and reading unfamiliar code. Not a fit if you want heavy mentorship or detailed specs handed to you. Apply via Ashby jobs link.
