Founding Engineer - Early-Stage AI Workflow Startup New York City | Onsite | $170k–$220k + meaningful equity I’m working with an early-stage AI company in New York that is building automation technology for a large, underserved operational market. The business is solving a real-world coordination problem where teams still rely heavily on phone calls, fragmented systems, manual admin and outdated workflows. Their product uses AI agents to automate complex scheduling, communication and verification workflows across multiple systems of record. This is a Founding Engineer role, joining a very small engineering team at a point where there is still significant scope to shape the product, architecture and engineering culture. What you’ll be doing You’ll own ambiguous, high-impact projects end-to-end, including: Building core product infrastructure and integrations with third-party systems Developing AI-powered workflow automation across communication-heavy operational processes Designing systems that handle context, memory, scheduling logic and compliance-sensitive actions Working across full-stack product development, backend systems and LLM-powered workflow The ideal person is a backend-leaning full-stack engineer who enjoys early-stage ownership and can operate without much hand-holding. You’ll likely have: 4–8 years’ full stack software engineering experience Backend experience with Node Strong database experience, ideally PostgreSQL or similar relational systems Experience owning products or systems from 0→1 Prior startup or founding engineer experience would be very relevant, especially if you’ve built products for complex professional or operational users. Why this could be interesting This is not a generic AI wrapper or a narrow feature role. The team is building software that sits inside messy, real-world operational workflows where reliability, context and judgment matter. It’s a strong fit for someone who wants: Early engineering ownership A product with real customer pull A technical problem that spans product, infrastructure, integrations and AI Meaningful equity upside Direct exposure to customers and product direction Package Equity: meaningful early-stage equity Small, founder-led team Visa sponsorship available for relevant candidates Location This is an onsite role in New York City . The team is building in person and looking for someone excited by the pace and ownership of an early‑stage environment. If you’re a product-minded full-stack engineer who enjoys building from zero, solving messy operational problems and working with AI-enabled workflows, this could be a very strong fit. #J-18808-Ljbffr Differential.
