About the role

Senior fullstack engineer focused on shipping user-valued features across Together AI’s core product surfaces, with high ownership in a fast-moving, collaborative environment.

Responsibilities

  • Ship improvements and new capabilities across Together AI's core product surfaces — Playground, Model Garden, Fine-Tuning, File Management, Batch Processing, and Model Evals
  • Own projects and features end-to-end, from data model and API integration through the user interface
  • Collaborate closely with other engineers to build clean, typed, reusable interfaces in our web application
  • Instrument and measure what you ship — add product analytics, monitor system health, and prove users are getting value with data
  • Work across design, product, and engineering to ship things that unlock user value
  • Raise the bar on frontend and fullstack quality across the team through code review and collaborative architecture decisions

Qualifications

  • 4–7 years of experience building and shipping real product to real users
  • Strong JavaScript/TypeScript fundamentals; TypeScript experience highly valued
  • Strong React expertise in a large-scale, production environment
  • Full-stack fluency: connect data model to API design to state management to the UI for clean, maintainable code and intuitive UX
  • A pragmatic approach to engineering—knowing when to move fast and when to slow down based on user value
  • Curiosity about AI and LLMs — understand the models and products you're building on top of
  • Adept at building and improving agentic workflows with good judgment for when to lean on AI
  • Cross-functional 'we ship it' mentality — no narrow ownership or finger-pointing
  • Next.js, Tailwind, and shadcn/ui experience is a plus
  • Familiarity with product analytics (e.g., Amplitude) and systems monitoring (e.g., Grafana) is a plus
  • Experience with CI/CD workflows is a plus
  • Experience with a backend language like Go or Python
