Founding Full Stack AI Engineer

About Us:

Sylvan Labs is tackling a critical gap in enterprise software — an underpenetrated space with billions in unrealized revenue potential. We are building a digital account manager agent that autonomously analyzes data, surfaces revenue insights, and automates follow-through. In the long run, we aim to multiply the output of every customer-facing team, transforming how businesses scale revenue from the ground up.

We are looking for a Founding Full-Stack AI Engineer who wants to redefine how enterprise companies drive revenue. We will only hire A-players and are highly willing to go above-market in ownership, equity, and cash compensation. We want world-class builders who are excited by the opportunity to be part of a category-defining company at the earliest stage. It won’t be easy. We’re going to move fast. But it’ll be fun.

The Role

As a Founding Engineer, you’ll work directly with the founders to architect, build, and scale the platform from 0 to 1. You’ll take full ownership of core features, shape the product roadmap, and drive technical execution in an environment that values speed, iteration, and excellence.

• Own and ship features end-to-end , from architecture to deployment.
• Build robust integrations + data ontology mapping tooling to streamline ingest and normalization of 3rd-party data, delivering enterprise-grade durability, scalability, and rapid customer deployments.
• Develop and maintain intuitive, functional UIs — pushing the envelope on AI product patterns and moving beyond simple chatbots to create more immersive, assistive experiences.
• Architect & build agentic solutions that automate complex workflows while advancing applied AI — from long-term agent memory to enhancing LLMs with reinforcement learning.
• Work closely with customers , iterating rapidly to refine and improve the product.

In this role, you will be responsible for building and scaling a high-impact platform that will shape the future of revenue operations.

Who You Are

• Been the top code contributor on your prior teams , not phased by the prospect of long hours when needed to ship and scale.
• A world-class software engineer who thrives in a fast-paced, high-ownership environment.
• Passionate about building high-quality products with speed and precision.
• Strong customer empathy — you understand user needs and build with them in mind.
• Proven track record building real-world ML/AI products with solid grasp of AI/ML fundamentals.

Plus factors :

• Prior experience as a founder / early-stage engineer.
• Experience with React , TypeScript , and Python.

This role is a rare opportunity to build foundational technology in a massive, underpenetrated market. If you're excited to own, build, and scale a category-defining platform, we’d love to talk.

Values

• In-Person Only. We are onsite in San Francisco — no remote or hybrid.
• A-Players Only. We hire exceptional talent and pay above-market rather than compromise. A-players attract A-players.
• Relentless Drive. You have a chip on your shoulder, thrive under pressure, and have extremely high urgency.
• Bias for Action. We don’t debate for weeks — we build, test, and iterate. Speed of execution is our advantage, and we expect everyone to push velocity.
• Craft Matters. You take pride in doing great work, not just getting things done. Thoughtful, intentional execution matters as much as speed.
• Fast Decisions, Fast Corrections. If someone isn’t the right fit, we move on quickly. Paid trials help us hire with conviction.
• Customer-First, Always. Internal speed should never slow down external results. If a customer feels stuck, we failed.
• Merit Over Politics. Titles reflect impact, not tenure. No ladder-climbing, no bureaucracy. Flat hierarchy.
• Attention to Detail. Excellence is in the details. Pixel-perfect UI and thoughtful execution separates great products from mediocre ones.

Most importantly: No Assholes, High Mutual Respect. We operate at high intensity, but with deep respect. Direct, honest, and no egos — just a shared obsession to win.
