These surfaces are how users experience the platform, and they need to be fast, intuitive, and something developers genuinely love using. That's what this role is about.\nWe're growing the Product Engineering team and looking for a fullstack engineer who's motivated by shipping things users genuinely value - not features that just look good in a slide deck. You'll plug directly into new and existing workstreams and start shipping quickly, working across our core product surfaces to improve existing capabilities and build new ones.\nThis is a high-ownership role on a small, fast-moving team, where one strong engineer moves the needle visibly. You'll see your work in production, instrument and measure it, and use that to shape what comes next.\nResponsibilities\nShip improvements and new capabilities across Together AI's core product surfaces - Playground, Model Garden, Fine-Tuning, File Management, Batch Processing, and Model Evals\nOwn projects and features end-to-end, from data model and API integration through the user interface\nCollaborate closely with other engineers to build clean, typed, reusable interfaces in our web application\nInstrument and measure what you ship - add product analytics, monitor system health, and prove users are getting value with data\nWork across design, product, and engineering to ship things that unlock user value\nRaise the bar on frontend and fullstack quality across the team through code review and collaborative architecture decisions\nRequirements\n4-7 years of experience building and shipping real product to real users\nStrong JavaScript/TypeScript fundamentals; TypeScript experience highly valued\nStrong React expertise in a large-scale, production environment\nFull-stack fluency: you connect the dots from data model to API design to state management to the UI, and know how to make the right call at each layer in service of clean, maintainable code and an intuitive user experience\nA pragmatic approach to engineering - you know when to move fast and when to slow down, and you make that call based on user value\nCuriosity about AI and LLMs - you want to understand the models and products you're building on top of, not just the code around them\nAdept at building and improving agentic workflows, with good judgment for when to lean on AI and when not to\nCross-functional \"we ship it\" mentality - no narrow ownership, no finger-pointing\nNext.js, Tailwind, and shadcn/ui experience is a plus\nFamiliarity with product analytics (e.g., Amplitude) and systems monitoring (e.g., Grafana) is a plus\nExperience with CI/CD workflows is a plus\nExperience with a backend language like Go or Python\nAbout Together AI\nTogether AI, the AI Native Cloud, is purpose-built for AI engineers. AI application developers get high-performance inference that scales reliably, fine-tuning and reinforcement learning for creating frontier-level specialized models, and pre-training at massive scale for fully custom intelligence, all around a marketplace of leading open models that teams can run, adapt, and own. Trusted by Cursor, Decagon, ElevenLabs, Salesforce, and Zoom, Together serves 400+ trillion tokens a month.\nCompensation\nWe offer competitive compensation, startup equity, health insurance and other competitive benefits. The US base salary range for this full-time position is: $160,000 - 230,000 + equity + benefits. Our salary ranges are determined by location, level and role.
