About Ditto: Ditto is redefining how data moves at the edge. Our mission is to make it seamless for developers to build resilient, real-time applications, regardless of network conditions. Whether you're in a stadium, airplane, or remote military base, Ditto's peer-to-peer sync engine ensures devices stay connected and data stays consistent, even without internet. With more than $145 million in funding and trusted by organizations like Chick-fil-A, Delta Airlines, and the U.S. military, Ditto powers mission-critical experiences across aviation, retail, travel, hospitality, defense, and more. As a globally distributed, fast-growing startup, we’re committed to building a diverse and inclusive team that reflects the wide range of perspectives needed to solve the world’s hardest connectivity problems. As a Senior Front End Engineer at Ditto, you own the experiences our customers interact with every day. You build polished, performant interfaces on top of a powerful edge-sync platform, and you work across the full stack to bring features to life — from the React and TypeScript front end down to the Rust services that power them. You partner closely with design and product to shape what we build and why, sweating the details of the customer's experience. Because the front end is where customers form their first and lasting impression of Ditto, you act as a strong advocate for user experience and quality, collaborating with backend, platform, and mobile engineers to ship cohesive products. This role suits a senior engineer who is comfortable setting technical and product direction, navigating ambiguity, and raising the bar for craft across the team. KEY RESPONSIBILITIES * Build polished, performant user interfaces: Design and ship high-quality, accessible web UIs in React, TypeScript, and modern CSS, with a relentless focus on performance, responsiveness, and craft. * Work across the full stack: You won't just be writing components in isolation. You will work end to end — building and consuming GraphQL and REST APIs and contributing to the Rust services and PostgreSQL data layer that power the product. * Partner with design and product: Collaborate closely with UI/UX designers and product managers to turn customer needs into well-scoped, well-designed features — helping shape not just how we build, but what we build and why. * Set technical direction and raise the bar: Make pragmatic architectural decisions, establish front-end best practices and reusable patterns, and mentor other engineers through thoughtful code review and design feedback. * Extend across platforms: Help bring key experiences to native mobile (iOS and Android) where it matters, ensuring a consistent, high-quality experience across web and device. WHAT YOU’LL NEED * 5+ years of professional front-end and full-stack experience building and shipping production web applications, with deep expertise in React, TypeScript, and modern front-end tooling. * Strong full-stack fundamentals spanning the front end and the services behind it, including hands-on experience designing and consuming APIs and working with relational databases such as PostgreSQL. * Working knowledge of Rust (or strong experience in another systems language and a genuine desire to work in Rust), enough to confidently contribute to and debug back-end services. * A strong product and design sensibility with a track record of partnering with UI/UX and product to ship experiences customers love — not just implementing tickets. * Demonstrated seniority and ownership, including setting technical and product direction, leading projects across teams, and mentoring other engineers. * Strong communication and collaboration skills, both written and verbal, with the ability to work effectively across product, design, and engineering in a distributed, remote-friendly team. NICE TO HAVES * Native mobile experience building or contributing to native iOS (Swift) and/or Android (Kotlin) applications. * Production Rust experience, particularly in web services, APIs, or other performance-sensitive systems. * Experience with GraphQL schema design and clients (e.g., Apollo or urql), and API design more broadly. * A strong eye for design and interaction with experience working directly in tools like Figma and translating designs into pixel-accurate, responsive UI. * Familiarity with local-first or offline-first application architectures, and the UX challenges of building on eventually-consistent data such as CRDTs. * Experience with observability and operational ownership — comfortable reading dashboards (e.g., Grafana) and debugging issues in production; familiarity with Kubernetes is a plus. * Experience contributing to design systems and component libraries that scale across multiple products and teams. * A track record in fast-growing or startup environments — comfortable with ambiguity and shifting priorities as the product and customer base scale.
