Role overview

Senior/Staff Software Engineer (AI Product) for a remote role in the United States. You will build polished, customer-facing AI features (not a backend AI research role) and lead initiatives end-to-end at a staff level.

Responsibilities

  • Lead design and delivery of customer-facing AI-powered features (e.g., copilots, assistants, summaries, intelligent workflows)
  • Own initiatives end-to-end: from concept and UX design through production deployment and iteration
  • Build high-quality frontend experiences that make AI accessible to non-technical users
  • Architect and implement full-stack systems connecting frontend, backend, and AI services
  • Establish best practices for AI product UX, performance, and reliability at scale
  • Serve as a technical leader, guiding architecture decisions and mentoring engineers
  • Collaborate closely with product and design to translate AI capabilities into usable interfaces

Requirements

  • 7+ years of software engineering experience with Staff-level scope and ownership
  • Proven track record of leading initiatives or owning products end-to-end
  • Frontend-leaning background (or full-stack with strong frontend expertise)
  • Experience shipping user-facing applications
  • Hands-on experience integrating AI into products, including LLMs and AI feature patterns
  • Strong product mindset and ability to translate complex AI into intuitive UX
  • Experience partnering with design and product teams and working in ambiguity

Tech stack (core)

  • TypeScript, React / Next.js
  • Node.js, serverless backends
  • AWS (or similar) cloud infrastructure
  • LLM platforms (e.g., OpenAI, Anthropic, Bedrock)
  • RAG pipelines and modern AI SDKs

Compensation

  • $225,000–$280,000 base + bonus + benefits (United States)
