## Job description

Who we're looking for

We're looking for Senior and Staff Software Engineers to join the Agentic Applications team at Supio. You'll build the software behind AI-powered products that legal professionals rely on for high-stakes work, so the code you ship has to be right.

We hire full-stack engineers who've gone deep. You're the person others turn to when a problem gets hard, with a strong backend foundation and the range to work across the rest of the stack. You work autonomously, partner well with product, design, and customers, and take a problem from fuzzy idea to shipped, operating software without waiting to be told what to build. You make good product calls and you leave the code, the system, and the team better than you found them.

We're a small team and the impact is direct. You'll work next to engineers who've built this platform from the ground up, and you'll help shape what we build next.

## What you'll build

You'll build and improve the software behind our AI-powered products, wherever your skills are most needed. You'll:

- Own problems end to end. Take ambiguous problems from idea to production: design, build, ship, and operate. You'll drive technical direction in your area and contribute to product decisions.
- Build systems that scale and hold up. Design services, interfaces, and data pipelines that stay reliable at high volume and with large, complex datasets.
- Work across the stack where it matters. Own work across frontend and backend, with the heaviest lift on the backend.
- Build with AI, and build AI-powered features. Use coding agents and AI tools to move faster, and help build, evaluate, and productionize LLM- and agent-driven capabilities with a focus on accuracy and reliability.
- Partner closely with product, design, and customer-facing teams. Understand what our users actually need and turn it into the right technical solution.
- Raise the bar. Review code thoughtfully, mentor teammates, and build the shared tools and practices that help others move faster. At the Staff level, you'll do this across teams and set technical direction for a broader area.

## Qualifications

- 8+ years of professional software engineering experience shipping and operating production systems. Staff candidates should show a track record of leading complex, cross-team technical work.
- Full-stack, with depth. Strong software fundamentals and a track record across the stack, with your strongest experience on the backend (services, APIs, data, infrastructure, or systems). You're comfortable owning the frontend too. We don't screen on a specific language.
- Production AI experience. You've built with LLMs or agentic systems (RAG, tool use, multi-agent orchestration), you know how to evaluate whether they work, and you use AI coding tools every day.
- Ownership and product judgment. You drive work end to end without hand-holding, make good tradeoffs, and partner well with product, design, and customers.
- Clear communication, written and in person.

Nice-to-haves

- Experience at both startups and larger companies
- Experience mentoring engineers or leading teams
- Experience with cloud platforms

## Compensation

As an early-stage startup, we offer a competitive compensation package that includes base salary, meaningful equity, and benefits. Equity grants are designed to ensure employees share in the long-term success and upside of the company.

Base Salary by Level and Location

Senior Software Engineer

- San Francisco: $190,000 – $240,000 annually
- Seattle: $180,000 – $230,000 annually

Staff Software Engineer

- San Francisco: $230,000 – $270,000 annually
- Seattle: $220,000 – $250,000 annually

This role is open at both the Senior and Staff levels. Final level, and therefore final compensation, is determined during the interview process based on the scope, depth, and impact demonstrated by the candidate. Within each range, placement depends on factors such as qualifications, skills, and experience.

## 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.
