Senior Product Engineer

Requirements

• 4+ years of frontend engineering experience building and shipping production features to real users
• Strong React fundamentals in production, including complex, stateful UIs that users depend on
• Strong TypeScript proficiency, with the ability to design clean typed interfaces across components, API boundaries, and application state
• Strong observability habits: you instrument what you ship, monitor whether it works, and use data to guide follow-up improvements
• Ability to absorb complex product and business requirements and translate them into correctly sequenced frontend implementations
• Fluency consuming APIs: you can read schemas, understand data shapes, handle loading and error states, and build typed web app interfaces without being blocked by backend engineers
• Next.js, Tailwind, and shadcn/ui experience is a meaningful plus
• Experience with billing, payments, or usage-based pricing UIs is a strong differentiator, including Stripe SDKs, metering displays, subscription states, checkout flows, or enterprise invoicing

Responsibilities

• Own Commerce’s frontend layer end-to-end: from consuming service APIs and building typed interfaces to delivering polished, accessible, user experiences, jumping in to backend systems when necessary to unblock product work in a fast-paced environment
• Break down complex product requirements and business logic into an iterative roadmap, sequence implementations correctly, and execute without needing step-by-step direction
• Champion the customer experience across commerce surfaces: notice friction, identify product and UX gaps, and turn recurring customer issues into clear opportunities for the team to improve
• Build reusable, well-typed React components on top of Together’s UI Platform and component library, making future Commerce work faster to ship
• Instrument, measure, and verify the success of your own features using data-driven metrics and signals including product analytics, web vitals, and error rates
• Catch and address edge cases, error states, and failure modes that matter in commerce contexts, including payment failures, quota overages, upgrade blockers, and inconsistent billing states
