Job description

About the Role

Join an early-stage, Y Combinator-backed AI marketing automation startup as a Founding Engineer (Full-Stack). You'll be one of the first engineers on the team, taking full ownership of features from concept through deployment — working directly with founders and customers to shape the product and infrastructure from the ground up.

What You'll Do

  • Own end-to-end feature development across the full stack: frontend (Vue.js/Nuxt), backend (Node.js/TypeScript), and AI agent integrations (LangGraph)

  • Architect and maintain robust PostgreSQL database schemas using Supabase, ensuring data integrity and performance

  • Manage deployments, background jobs, and infrastructure using Render and Inngest; maintain dedicated deployments on Microsoft Azure

  • Apply user-centric design thinking across the full product lifecycle

  • Collaborate closely with the operations team and customers (via Slack and Notion) to align technical solutions with real user needs

  • Contribute to tooling and internal workflows using Linear, GitHub, Slack, and Notion

What We're Looking For

Required:

  • 2+ years of professional software engineering experience delivering full-stack web applications

  • Hands-on experience with TypeScript and Node.js backend development

  • Strong proficiency with PostgreSQL and relational database design

  • Frontend experience with Vue.js + Nuxt, or React/Next.js

  • Experience owning features end-to-end — from concept through deployment to maintenance

  • Bachelor's or Master's degree in Computer Science or a related field, or equivalent practical experience

  • Willing and able to relocate to San Francisco and work on-site

Nice to Have:

  • Experience deploying and managing applications with Render and Inngest; familiarity with Microsoft Azure

  • Background or exposure to marketing technology or AdTech

  • Experience integrating with LLM APIs (OpenAI, Anthropic, Google, etc.) or building AI/ML-powered features

  • Familiarity with serverless workflows or event-driven architecture

Compensation & Benefits

  • Salary: $175,000 – $200,000 USD annually

  • Equity as a founding team member

  • Visa sponsorship available

Location

This role is on-site in San Francisco, CA. Candidates must be willing and able to work from the San Francisco office full-time. Relocation support is available.
