Engineers here design, create, and deploy generative AI products. This is a full-stack role where the person will work across the entire technology stack on ambitious problems. What the role owns: Developing full-stack generative AI functionality that directly impacts how lawyers review, edit, and manage contracts Shipping high-performance user interface code alongside backend systems that process and analyze millions of contracts reliably Designing pipelines that orchestrate large language models, data extraction, and clustering algorithms at scale Collaborating daily with designers, legal subject matter experts, and other engineers to reimagine the way lawyers work in the age of AI Who they are looking for: The ideal candidate brings experience across both frontend and backend development, with particular strength in at least one area. They should be comfortable moving between building reactive user interfaces and designing robust data pipelines. Experience with LLMs or machine learning infrastructure is a plus, but curiosity and a willingness to learn matter more than deep AI expertise. Who Thrives Here The company is likely a strong fit for someone who: Loves writing code but cares about impact more. The team is composed of engineers at heart, but the number one goal is building the best possible product—which means making pragmatic choices and finding 80/20 solutions. Would describe themselves as relentlessly resourceful. Has a strong internal sense of urgency and a bias toward doing things today rather than tomorrow. Has prior startup experience (preferred but not required). Is genuinely excited about the adventure of building a company. What the Team Values in People The company looks for individuals who: Ship every day: Launch frequently. Know how to descope aggressively to get results fast. Maintain fast cycle times: Think in hours, not days; days, not weeks; weeks, not months. Push the pace and use speed as a competitive weapon. Are generative: Have more ideas than time. Do not require someone to provide constant direction. Are resilient: When bad news arrives, respond with "good." Do not give up easily. Are customer obsessed: Talk to customers regularly. Do whatever it takes to make them succeed. Like to run hard: Recognize that life is short, and that working twice as hard can often yield ten times the results. Competitive base salary: Up to $485,000 (equity separate). Final offers are determined by experience, expertise, and other factors. Medical benefits: Comprehensive medical, dental, and vision plans to suit the needs of the employee and their family. Unlimited PTO: Time off to recharge, stay healthy, and bring the best self to work. Office extras: A generous office space in downtown San Francisco includes snacks, coffee, a dedicated exercise/workout space, and regular team-building events and activities. #J-18808-Ljbffr Underdog.io -Apply to top tech jobs in 60 seconds.
