# Senior Software Engineer, Full-Stack (Agentic Platform) at Supio

- **Company:** Supio
- **Location:** Seattle, WA
- **Employment:** full-time
- **Work type:** hybrid
- **Posted:** 2026-07-07
- **Last confirmed live:** 2026-09-08
- **Apply:** https://jobs.gem.com/supio/am9icG9zdDqA6mT47ZS3M7f6TeG6qv36

## Job description

Who we're looking for

We're hiring senior/staff, product-minded full-stack engineers to build Supio's agentic platform — applied AI at the core, in high-stakes, real-world legal workflows. You build product end-to-end in TypeScript across the stack, from the interfaces customers touch to the services behind them. You have hands-on experience shipping LLM/AI systems in production, you're fluent using coding agents in your daily workflow, and you operate with real autonomy. You've thrived in a startup environment and you're excited to build greenfield.

## What you'll build

(scope depends on team placement)

- Agentic platform capabilities spanning voice calling & transcription, medical/financial records extraction, and legal document drafting
- The agent runtime — prompt/tool architecture, skill and prompt management, and cost/performance optimization
- The core full-stack application customers work in every day
- Production LLM-driven features, plus the evaluation, tooling, and monitoring that keep them accurate and observable at scale

You won't just ship features — you'll shape the architecture and technical direction of a fast-evolving, AI-native platform, with senior autonomy and end-to-end ownership.

## What you'll bring (must-haves)

- 10+ years of professional software engineering experience
- True full-stack depth. You own product end-to-end, front to back. This isn't a front-end or backend specialist role; you're comfortable across the whole stack (React/TypeScript on the front end and modern backend services, APIs, and data pipelines).
- Strong product sense. You build customer-facing product and translate real user needs into technical solutions
- Hands-on applied AI/LLM systems experience. You've built real systems end-to-end and can speak to what you owned and what broke in production
- Fluency with coding agents as part of how you build
- Startup background. Comfortable with ambiguity, speed, and greenfield
- Autonomy and ownership. Able to meet in-office/hybrid expectations in Seattle or San Francisco

## Nice to have

- Prior experience at AI-native companies
- Formal ML background (optional — practical AI fluency matters more than credentials)

## Compensation

Competitive package of base salary, meaningful equity, and benefits.

Base Salary: $200,000–$255,000 annually

Actual compensation depends on qualifications, skills, experience, and location.

## About Supio

## Company Overview
- **One-liner**: Supio is an AI platform purpose-built for personal injury and mass tort law firms, delivering human-level analysis of complex legal records to help firms settle bigger and win more.
- **Entity Type**: Private (Series B, $91M total funding)
- **Headquarters**: Seattle, Washington, United States (with additional office in San Francisco)
- **Founded**: 2021
- **Founders**: Jerry Zhou (Co-Founder & CEO) and Kyle Lam (Co-Founder & CTO)

## Core Business
- **Primary industry**: Legal technology (AI for plaintiff-side personal injury and mass tort litigation)
- **Target customers**: B2B – personal injury law firms, mass tort firms, and plaintiff legal teams
- **Mission or purpose**: “Level the playing field for injured people — ensuring evidence is never missed, injuries are never undervalued, and justice is never lost to the sheer volume of information humans must process.”

## Products & Services
- **Supio Agent**: An end-to-end agentic AI platform that connects every dimension of a plaintiff practice — from intake through resolution, case intelligence through firm-wide analytics. It handles document organization, medical record review, drafting demands, litigation documents, and case insights.
- **AI Assistant**: Acts as a paralegal, nurse consultant, and strategic attorney — organizes documents, flags medical issues, and refines arguments.
- **Medical Chronologies**: Creates precise chronologies from medical records with filters and AI chat capabilities.
- **Case Signals**: Identifies missing records, undiagnosed injuries, and other key gaps in a case.
- **Drafting Suite**: Drafts interrogatories, deposition questions, statements, and other legal documents aligned to firm style.
- **Case Economics**: Provides billing snapshots, ledgers, and valuation tools.
- **Demands**: Auto-generates injury descriptions and ICD codes, editable via chat.
- **Supio API & Connectors**: Integrates with existing case management systems and document platforms for seamless workflows.

## Market Standing
- **Valuation / Market Cap**: Not publicly disclosed
- **Key Metric**: Total Funding – $91M (Seed $6M in May 2023, Series A $25M in Aug 2024, Series B $60M in May 2025)
- **Notable Investors / Partners**: Lead investor Sapphire Ventures (Series A & B); partners include Thomson Reuters and leading Trial Lawyer Associations
- **Growth Signals**: 135 employees (64.7% YoY growth); platform has supported over $1 billion in settlements; one firm saved 437 hours across six cases; $500–$1,000 saved per case; expanding into Canada (Toronto hires)

## Competitive Advantages
- **Agentic AI purpose-built for plaintiff law** – not a generic AI tool bolted onto legal workflows, but an end-to-end platform designed from the ground up for personal injury and mass torts.
- **Security & Compliance** – SOC 2 Type II certified, HIPAA, PHIPA, and GDPR compliant; client data never leaves their control and never trains foundation models.
- **Human-in-the-loop QA** – Combines specialized AI with expert human accuracy to ensure reliability.
- **Deep integrations** – Connects with major case management systems and offers an API for custom workflows.
- **Partnerships** – Backed by Thomson Reuters and top trial lawyer associations, giving authoritative intelligence.

## Strategic Focus
- Continue to dominate the plaintiff personal injury and mass tort AI market.
- Expand geographically (recent Canada hiring push) and scale the agentic platform to larger firms.
- Deepen product capabilities across pre-litigation and litigation, with an emphasis on firm-wide analytics and case economics.
- Grow headcount across engineering, customer success, sales, marketing, and product to support sustained leadership in the PI industry.

## Why Work Here
- **Culture & Mission**: “AI for people, not systems” – the team is passionate about leveling the playing field for injured people and transforming how legal professionals work.
- **Work Model**: Hybrid – focused remote work blended with in-person collaboration at offices in San Francisco (SOMA) and Seattle (HQ). Flexibility is core, with intentional in-person connection for shared momentum.
- **Engineering Culture**: “AI-native thinking” – AI is baked into the DNA of every experience, not bolted on. Teams work on ambitious goals that directly impact real cases.
- **Benefits**: Comprehensive benefits designed to support health, growth, and life beyond the office.
- **Growth Stage**: With $91M raised and a clear growth trajectory, employees can have high impact in a scaling organization.
