Job description

About Us
At Union, we are solving one of the hardest challenges in AI infrastructure today: enabling high-velocity iteration while maintaining seamless production-readiness for AI workloads at scale.
Flyte, the open-source project we steward, has emerged as the modern standard for data and AI orchestration, and is trusted by leading technology organizations including LinkedIn, Stripe, and Wayve to run millions of mission-critical workflows on the platform. These workflows comprise data preparation, model training, and scaled inference spanning thousands of GPUs, all major clouds, and on-premise infrastructure.
We have a technical founding team who created Flyte while at Lyft, a deep bench of infrastructure experts from top companies, and have raised from top investors like NEA and Nava Ventures.
About the Role
Union is building the orchestration layer for modern AI and ML workloads. We're hiring a Front-End Software Engineer to build intuitive, high-performance experiences on top of complex distributed systems.
The surface you own is data-dense and live. Workflow runs stream state as they execute, task lists run long, logs and timelines update in real time, and a customer debugging a failed run needs the console to stay fast and legible while thousands of rows move underneath them. This is closer to building a monitoring or observability console than a marketing site or a CRUD app.
You'll work across the Flyte v2 experience, from launching workflows to monitoring runs, debugging failures, managing applications, and onboarding new organizations, in close partnership with product, design, backend, infrastructure, and customer teams.
This role is hybrid, based out of our Seattle office.
What You'll Do
  • Build and maintain a modern React and Next.js application in TypeScript.
  • Develop features across Run Details, Actions, Apps, Settings, workflows, and onboarding.
  • Implement complex UI patterns including infinite scrolling, virtualization, real-time updates, streaming, and timelines.
  • Build interactive data tables with sorting, filtering, pagination, and efficient rendering at volume.
  • Create reusable, responsive components using Tailwind CSS, Headless UI, and our design system.
  • Work with gRPC and Connect APIs and protobuf for type-safe data communication.
  • Use TanStack Query and Zustand for server and client state management.
  • Collaborate with backend engineers to influence API design and deliver cohesive features.
  • Contribute to front-end architecture, technical decisions, testing, and performance improvements.
  • Work directly with customers to understand problems, debug issues, and improve the product.
What We're Looking For
  • 3+ years of professional experience building modern web applications.
  • Strong experience with React, Next.js, and TypeScript.
  • Hands-on work with real-time data, infinite scrolling, virtualization, complex state, or high-volume datasets. This is the part of the job that's hard to fake.
  • A real understanding of front-end architecture and performance optimization.
  • Experience with modern build tooling such as Vite or Webpack.
  • A bias toward simple, reliable, maintainable code and thoughtful user experiences.
  • Clear communication and effective collaboration across teams.
  • A bachelor's degree in computer science or equivalent professional experience.
Preferred Experience
  • Workflow orchestration, developer tools, cloud infrastructure, or distributed systems.
  • Kubernetes, containers, gRPC, protobuf, or data visualization.
  • Flyte, Ray, Spark, SageMaker, or similar AI and ML platforms.
  • Working directly with enterprise customers.
Our Stack
  • Core. React, Next.js, TypeScript.
  • Styling. Tailwind CSS, Headless UI, internal design system.
  • State and data. TanStack Query, Zustand, gRPC and Connect, protobuf.
  • Tooling. Vite, Webpack.

Benefits & Belonging
At Union.ai we know that employees who feel their best can build amazing things and we are proud to offer best in class benefits that will continually evolve and grow as the needs of our employees do. Benefits may vary based on country.
  • Excellent medical - We pay 100% of your premiums and 90% for your dependents
  • Generous dental and vision plans- We pay 90% of the premiums for you and your dependents
  • Meaningful equity in the form of options - all employees are owners here
  • Unlimited time off + 12 company holidays
  • 401K match - Union.ai matches 100% of contributions up to the first 3%, and 50% up to 5%
  • 12 weeks paid parental leave for primary and secondary caregivers
  • Flexible work schedule (some restrictions apply)
  • For in office employees: Lunch provided onsite and well stocked kitchen with snacks and drinks.

We believe that our differences are what bring us together to achieve truly special outcomes. We strive to be inclusive and focus on building teams that embody that quality too. Union.ai is an equal-opportunity employer and we encourage you to apply, even if your experience doesn't align exactly with our job description.
