Our innovative approach blends technology with deep legal expertise, making us a leader in our field. We go beyond surface-level AI to deeply understand our customers’ daily needs, empowering law firms with unparalleled data insights. Supio delivers human-level, accurate analysis of complex data and legal records, quickly and efficiently bringing critical insights when they matter most. Trusted by top litigation lawyers, our platform has supported over $1 billion in settlements.\nHeadquartered 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.\nWe're looking for passionate team members who are motivated by our mission and ready to help us achieve it.\nWho we're looking for\nWe'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.\nWe 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.\nWe'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.\nWhat you'll build\nYou'll build and improve the software behind our AI-powered products, wherever your skills are most needed. You'll:\nOwn 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.\nBuild systems that scale and hold up. Design services, interfaces, and data pipelines that stay reliable at high volume and with large, complex datasets.\nWork across the stack where it matters. Own work across frontend and backend, with the heaviest lift on the backend.\nBuild 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.\nPartner closely with product, design, and customer-facing teams. Understand what our users actually need and turn it into the right technical solution.\nRaise 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.\nQualifications\n8+ 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.\n 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.\n 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.\nOwnership and product judgment. You drive work end to end without hand-holding, make good tradeoffs, and partner well with product, design, and customers.\nClear communication, written and in person.\nNice-to-haves\nExperience at both startups and larger companies\nExperience mentoring engineers or leading teams\nExperience with cloud platforms\nCompensation\nAs 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.\nBase Salary by Level and Location\nSenior Software Engineer\nSan Francisco: $190,000 - $240,000 annually\nSeattle: $180,000 - $230,000 annually\nStaff Software Engineer\nSan Francisco: $230,000 - $270,000 annually\nSeattle: $220,000 - $250,000 annually\nThis 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.\nCompensation & Benefits\n Competitive Salary + Meaningful Equity\n 401(k)\n Health, Dental, Vision, and Life Insurance\n Flexible Time Off + Holidays\n High-autonomy work environment, every Tuesday is a Remote Work Day\n DoorDash subsidies for breakfast and dinner; Daily lunch options\n Boba Wednesdays\n Monthly commuter subsidies and pre-tax parking contribution\n Team gatherings and offsites\nE-Verify Participation Notice\nSupio participates in E-Verify, an employment authorization program through the U.S. Department of Homeland Security and the Social Security Administration. \nEqual Employment Opportunity (EEO) Statement\nSupio is committed to creating a diverse environment and is proud to be an equal opportunity employer.
