We are looking for a Principal Software Engineer to lead the design and implementation of a Server-Driven UI (SDUI) platform that powers cross-platform user experiences across mobile and web. This role spans front-end, back-end, and infrastructure, with a particular focus on developer ergonomics, scale, and performance. You'll also help define a DSL that allows teams to declaratively build UI and interactions, and build the systems that interpret and deliver those experiences in real-time. This is a high-impact, cross-cutting technical role — ideal for an engineer who enjoys shaping system architecture, building reusable primitives, and mentoring engineers across domains.

  • Design and implement the core SDUI platform, including schema evolution, layout/interaction models, and runtime execution.
  • Own and evolve a custom DSL that declaratively defines UI components and their behavior.
  • Build robust, scalable backends (typically BFFs) that drive dynamic UI delivery across platforms.
  • Collaborate with mobile, web, and backend teams to deliver cohesive developer and user experiences.
  • Lead architectural decisions around full-stack delivery — including caching, versioning, fallbacks, and progressive rendering.
  • Set technical direction and establish best practices for system reliability, testing, observability, and developer ergonomics.
  • Partner with product and platform teams to prioritize foundational capabilities and longer-term scalability.
  • 10+ years of professional experience in software engineering, including full-stack or platform roles.
  • Proven expertise in building scalable backends (e.g., BFFs, GraphQL/REST APIs, caching layers).
  • Deep experience with at least one major frontend technology (e.g., React, React Native, SwiftUI, Jetpack Compose).
  • Strong systems thinking and architecture skills - able to break down complex UX/backend interactions into reusable, extensible building blocks.
  • Familiarity with Server-Driven UI paradigms and cross-platform delivery models.
  • Solid understanding of DSL design and implementation, including parsing and schema validation.
  • Strong programming language fundamentals (e.g., ASTs, interpreters, compilers, metaprogramming).
  • Track record of leading initiatives with broad technical scope and multiple stakeholders.
  • Strong AI fundamentals and familiarity with working on AI technologies.
  • Experience designing or working with custom DSLs, markup languages, or declarative UI systems.
  • Exposure to schema evolution, compatibility guarantees, and platform versioning strategies.
  • Hands-on experience with mobile frameworks (iOS/Android) and how SDUI maps to native rendering.
  • Contributions to open-source UI frameworks or backend platforms.
  • Experience building tools or frameworks that improve developer velocity and experience.
  • You'll be at the forefront of transforming how UI is built, delivered, and evolved at scale.
  • Opportunity to work across the stack and influence system design from the ground up.
  • Join a team that values clean architecture, developer experience, and product velocity.
