Job Description
Location: New York City, NY (on-site, 5 days per week) Employment Type: Full time Experience: 7+ years of hands-on full-stack product engineering Industry: Developer tools and AI Openings: Multiple
About the Opportunity
A fast-growing, venture-backed developer tools and AI company in New York City is hiring Senior Product Engineers. The company built a CI platform now used by more than 3,000 companies, reached about $10 million in ARR in under two years, grew revenue more than 5X since the start of 2026, and has raised about $58.5 million through Series B. With a team of roughly 37 people, it is now expanding into AI-powered developer tools, agent infrastructure and coding workflows.
This role is for a senior, hands-on full-stack engineer who has built products from the ground up in a startup or high-growth environment. You will work directly with the technical founders and other experienced engineers to shape product direction, make key architecture decisions, and take new products from first concept through launch and customer adoption. Engineers here build net-new products rather than maintain an established roadmap.
What You'll Do
- Own complete product surfaces from early ideation and systems design through development, launch, customer feedback and iteration
- Build and evolve developer tools and AI-powered product experiences used by engineers
- Work across user interfaces, backend services, APIs and supporting infrastructure
- Partner directly with the technical founders to shape product ideas, validate them and bring them to market quickly
- Make meaningful architecture and systems-design decisions across the full stack
- Prototype and ship AI-powered features, including natural-language interfaces, automation, agent-based workflows and developer productivity tools
- Build polished, high-performance product experiences across analytics, observability, debugging and agent platforms
What You Bring
- 7+ years of relevant, hands-on full-stack product engineering experience
- Proven experience personally designing, building and launching a meaningful product or major product surface from 0 to 1
- Experience in a startup, scale-up or high-growth environment with significant autonomy and ownership
- Strong, recent experience with React, TypeScript and modern frontend development
- Backend engineering depth and experience making systems-design and architecture decisions
- Experience building products used by developers or other technical users, including APIs, SDKs, developer platforms or developer-facing tooling
- Experience at a developer tools or infrastructure startup building products for engineers
- Experience shipping applied AI or LLM-powered features, or a strong track record of using coding agents or agentic tools to materially improve your engineering workflow
- Ownership of product decisions from ideation through launch and iteration
- Ability to move quickly, work independently and make sound decisions in ambiguous environments
- Strong product judgment and an understanding of how technical decisions affect the user experience
This Role May Not Be the Best Fit If
- Your experience has been mainly within large, highly structured organizations without meaningful startup or high-growth experience
- Your background is mainly DevOps, SRE, infrastructure or platform operations without substantial product ownership
- Your experience is limited to either frontend or backend development rather than full-stack product engineering
- You have not personally taken a meaningful product from idea to production
- You prefer remote or hybrid work
- You require current or future visa sponsorship
Technical Environment
- React and TypeScript
- Go
- Firecracker
- GitHub Actions
- AI and large language models, including Claude
- APIs and SDKs
- CI/CD and developer tooling
- Full-stack development and systems design
Not every technology listed is required. The strongest emphasis is on React and modern frontend development, backend depth, systems design, developer-facing products, and meaningful applied AI or agentic engineering experience.
Why Join
- Build products that don't exist yet instead of maintaining someone else's roadmap
- Own products from first idea through daily customer use
- Help expand an established developer infrastructure platform into AI-powered developer tools, agent infrastructure and coding workflows
- Join a well-funded company with strong revenue growth, serving thousands of businesses
- Work on a small, highly technical team with minimal management layers
- Collaborate directly with the technical founders
- Make product and architecture decisions that will shape the platform for years
- Work in an engineering culture that fully embraces AI-native software development
- Competitive base salary and equity
