Join a small, senior engineering group to ship end‑to‑end product slices that make Horizon indispensable for real users - owning everything from a quick wireframe and demo to the production service to the observability and page that wakes you up at 2 a.m. You'll partner directly with our CEO, VP of Product, other product engineers, and early customers, turn field signal into working software fast, and help us confidently identify where we can take the market then deliver. Horizon helps developers deploy, scale, and manage MCP servers with zero configuration—built for modern AI development workflows with production-ready infrastructure. This role sits at the intersection of an emergent market where AI and LLM tooling are reshaping how development teams operate.

Shape technical direction and architectural decisions for Horizon
Mentor product engineers on your team on systems thinking, reliability patterns, and shipping discipline
Develop deep product knowledge of the AI/LLM tooling space, MCP ecosystem, and how Horizon fits into emerging patterns
Establish and refine our approach to operational excellence: sustainable on-call practices, incident response patterns, observability standards that scale
Participate in on-call/incident response and set the standard for how we handle production issues
Requirements:
8+ years of full-stack engineering experience, with demonstrated success shipping early-stage products from 0 to 1.0 and scaling them beyond
Deep proficiency in TypeScript across the full stack
Comfortable owning UI/UX implementation
Python experience is a bonus
