About the Role We're looking for a Senior Full-Stack Engineer to help one of our new partners build a next-generation AI product from the ground up. You'll work directly with a co-founder to design and deliver integrations that connect with the tools sales teams rely on every day—email, CRMs, and messaging platforms. If you enjoy solving meaningful problems, working with modern TypeScript tooling, and delivering well-tested, reliable solutions, we'd love to hear from you. Responsibilities Build backend-first features using TypeScript, Node.Js, Cloudflare, and API-driven architectures. Develop and maintain integrations with tools like Outlook, HubSpot, Slack, and iMessage. Design simple, reliable, and maintainable solutions that prioritize clarity and product value. Collaborate directly with a co-founder to refine requirements, align on expectations, and make decisions quickly. Troubleshoot and debug issues across multiple external APIs and integration layers. Contribute to front-end development when needed, particularly using React. Seek clarification early and ensure alignment on direction before implementing complex features. Support rapid iteration and contribute to shaping an early-stage product. Core Requirements 5+ years of experience building scalable applications with TypeScript, including Node.Js and modern React. Strong backend fundamentals, especially with API consumption, integrations, and asynchronous workflows. Hands-on experience working with third-party APIs (OAuth, authentication flows, webhooks, rate limits). Ability to produce clean, maintainable, and production-ready code with strong testing practices. Experience with cloud-based environments— Cloudflare Workers, serverless patterns, or similar. Strong debugging skills and comfort working in integration-heavy codebases. Product-oriented mindset with the ability to prioritize features that deliver real value. Nice to Have Experience integrating with sales or productivity tools (CRMs, messaging apps, email platforms). Background in early-stage startups or fast-evolving environments. Familiarity with AI-driven workflows or LLM-powered applications. Other Traits Pragmatic approach to engineering, focusing on effective and maintainable solutions. Proactive communicator who seeks alignment before implementation. Adaptable and comfortable adjusting to evolving product requirements. Strong sense of ownership, curiosity, and initiative.
