Technical Lead - Fullstack

Description Jump is transforming the live sports experience with the only end-to-end fan engagement platform built specifically for sports teams and venues. By focusing on aligned incentives between teams and fans, our platform unifies ticketing, merchandise, and game day operations - creating a smoother, more fan-friendly experience. Founded in 2021 by e-commerce innovator Marc Lore, MLB legend Alex Rodriguez, and entrepreneur Jordy Leiser, we’ve raised $60 million from top investors including Alexis Ohanian’s Seven Seven Six and Forerunner Ventures. Our platform powers teams across the NBA, WNBA, and NWSL helping them boost ticket sales and deliver innovative fan experiences. We’re a remote-first team driven by core values - begin and build with trust, play like the underdog, win as a team, and do your thing. If you’re collaborative, adaptable, and eager to shape the future of live sports, Jump is the place for you. The Role We’re looking for a Technical Lead to help define and scale the technical direction of our consumer-facing platform while raising the bar for engineering quality, execution speed, and AI-native development practices. As the Technical Lead, you’ll be the primary technical leader for the consumer pod - working cross functionally to shape architecture, make high-leverage technical decisions, and ensure we consistently ship high-quality consumer experiences. You’ll operate across a modern TypeScript stack, making pragmatic tradeoffs between speed, scalability, maintainability, and user experience as the product and organization evolve. You’ll be expected to stay deeply hands-on, set a high bar for engineering excellence, and actively shape how the team builds software - including how we use AI to fundamentally increase engineering velocity and quality. What You’ll Do - Own and evolve the technical direction of the consumer platform, setting long-term architectural vision while making pragmatic, day-to-day technical decisions - Make high-leverage architectural decisions across a modern TypeScript ecosystem, balancing speed, scalability, product quality, and long-term maintainability - Serve as the technical “north star” for the pod through design reviews, code reviews, and deep technical guidance - Stay deeply hands-on in the codebase, contributing to complex features, debugging production issues, and driving system design work end-to-end - Partner closely with Product, Design, and Engineering leadership to shape roadmaps, challenge assumptions, and translate ambiguous problems into clear technical direction - Raise the bar for engineering quality across performance, reliability, testing strategy, observability, and developer experience - Actively mentor engineers by modeling strong engineering judgment - Define and operationalize AI-assisted engineering workflows that meaningfully increase team velocity (not just individual productivity), using tools like Cursor, Codex, Claude, and others - Participate in hiring and interviewing, helping to maintain a high technical bar of the organization - Collaborate across engineering teams to influence shared systems, infrastructure, and cross-cutting platform decisions What You’ll Bring - 8+ years of software engineering experience with deep expertise in modern full-stack web development - Proven track record of owning or significantly influencing architecture for consumer-facing web products at scale - Strong mastery of TypeScript, React, Node.js, and Next.js, with a bias toward building maintainable systems over short-term hacks - Experience building and scaling modern full-stack applications using GraphQL, Apollo, and AWS, with strong expertise in both relational and NoSQL databases including Postgres and DynamoDB. - Demonstrated ability to operate as a technical leader - Exceptional engineering judgment — able to make clear decisions in ambiguous spaces with incomplete information - Strong, hands-on coding ability with a willingness to stay close to the implementat
