Founding Engineer (Full-Stack)

About the Role

We're a seed-stage, Y Combinator-backed AI marketing automation company building a full-funnel platform that automates market intelligence, content production, campaign management, and analytics for enterprise brands. Our technology replaces manual campaign execution with intelligent, AI-driven automation - helping marketing teams improve return on ad spend, lift conversion rates, and dramatically cut production costs.

We're looking for a Founding Engineer (Full-Stack) to join our small, high-ownership team on-site in San Francisco. This is a foundational role: you'll work directly alongside the founding team, shape the architecture, and own features end-to-end from concept through deployment and maintenance.
What You'll Do

• Take full ownership of features across the entire stack - frontend, backend, infrastructure, and data.
• Build and maintain frontend experiences using Vue.js / Nuxt .
• Develop robust backend services with Node.js and TypeScript , including event-driven background jobs via Inngest .
• Architect and manage PostgreSQL schemas (via Supabase ), ensuring data integrity and performance.
• Manage deployments and infrastructure on Render and maintain dedicated deployments on Microsoft Azure .
• Integrate AI agents and language model workflows using LangGraph and LLM APIs (e.g., OpenAI, Anthropic, Google).
• Collaborate closely with the operations team and customers via Slack and Notion to keep solutions tightly aligned with real user needs.
• Contribute to product thinking, applying user-centric design principles across the full product lifecycle.
• Work with Linear, GitHub, Slack, and Notion as core collaboration and delivery tools.

What We're Looking For

Must-haves:

• 2+ years of software engineering experience delivering full-stack web applications in production.
• Hands-on, proven experience with TypeScript / Node.js backend development.
• Solid command of PostgreSQL - schema design, query optimization, data integrity.
• Experience owning end-to-end features or projects, from initial concept through deployment and ongoing maintenance.
• Frontend development experience with Vue.js + Nuxt or React / Next.js.
• Willingness and ability to work on-site in San Francisco (relocation required if not already local).
• Bachelor's or Master's degree in Computer Science or a related field, or equivalent practical experience.

Nice-to-haves:

• Experience deploying and managing applications with Render and Inngest ; familiarity with Microsoft Azure deployments.
• Previous exposure to marketing technology, AdTech, or digital advertising platforms.
• Experience integrating language models and AI/ML APIs (OpenAI, Anthropic, Google, etc.).
• Familiarity with serverless workflows or event-driven architecture (e.g., Inngest).
• Comfort working directly with customers and translating feedback into product decisions.

You'll thrive here if you:

• Are energized by early-stage ambiguity and the chance to shape a product from the ground up.
• Prefer breadth and ownership over narrow specialization.
• Are a self-starter who moves fast, communicates openly, and takes pride in shipping things that matter.

Compensation & Benefits

• Salary: $175,000 - $200,000 USD per year
• Equity participation at a founding-team level
• Visa sponsorship available
