Our innovative approach blends technology with deep legal expertise, making us a leader in our field.

Supio delivers human-level, accurate analysis of complex data and legal records, quickly and efficiently bringing critical insights when they matter most.

Headquartered in Seattle with an office in San Francisco, we raised $60M Series B in April 2025 led by Sapphire Ventures with Mayfield and Thomson Reuters Ventures, bringing total funding to $91M. We're scaling rapidly and looking for exceptional talent to join us in this next phase of growth.
​​We're looking for passionate team members who are motivated by our mission and ready to help us achieve it.
Who we’re looking for:
  • Hands-on builder who ships—you're comfortable owning problems end-to-end in a fast, early-stage environment.
  • Deep experience with LLMs, agent architectures, and turning research into reliable products.
  • Strong product sense: you translate messy legal/medical workflows into usable, trustworthy automation.
  • High ownership and bias to action; you thrive with autonomy and ambiguity.
  • Customer-obsessed, rapidly learns new domains and iterates based on impact.
What you’ll do:
  • Design and ship autonomous agentic systems that plan, reason, and execute multi-step workflows.
  • Build at scale: ingest and structure millions of unstructured documents (medical records, insurance files, legal PDFs).
  • Fine-tune and deploy language models for extraction, entity linking, retrieval, and predictive analytics.
  • Own the stack—from modeling and tool orchestration to production deployment, monitoring, and iteration.
  • Define evaluation/measurement frameworks; improve quality with experiments and data analysis.
  • Partner with legal/clinical experts and engineering to deliver measurable business outcomes.
Qualifications:
  • Proven track record in building and deploying production ML/LLM systems (agent frameworks, tool use, orchestration).
  • Strong with Python and modern ML tooling (vector stores, embeddings/RAG, evaluation, tracing); solid software engineering fundamentals.
  • Experience processing unstructured documents at scale (pipelines, OCR, normalization, metadata).
  • Cloud/MLOps experience (AWS/GCP/Azure, containers, CI/CD, observability).
  • Excellent judgment, communication, and bias-for-evidence; write clear, discoverable notes and docs.
  • Nice to haves: legal/healthcare data exposure; safety/ethics/governance for AI; startup experience.
