About the Role
An early-stage startup is hiring a Founding Full Stack Engineer to help build its product from the ground up. This role will work closely with the founding team to design, develop, and ship the initial versions of the platform while laying the technical foundation for future growth.
This position offers high ownership, broad responsibility across the stack, and direct impact on product direction, architecture, and engineering culture.
What You’ll DoBuild the initial product and core features from zero to production
Design and implement frontend and backend systems with scalability in mind
Own services, data models, and APIs end to end
Collaborate directly with founders on product requirements and technical tradeoffs
Make foundational decisions around architecture, tooling, and infrastructure
Write clean, maintainable code and establish engineering best practices
Set up deployment pipelines, monitoring, and basic DevOps workflows
Help hire and mentor future engineers as the team grows

Frontend: React, TypeScript, Next.js
Backend: Node.js (Express/NestJS) or Python (Django/FastAPI)
Databases: PostgreSQL, Redis
Cloud & Infrastructure: AWS or GCP, Docker, CI/CD
APIs: REST, GraphQL
Version Control: Git (GitHub or similar)
6+ years of professional software engineering experience
Strong full stack background with modern JavaScript/TypeScript
Experience building products from early stage through production
Solid understanding of backend systems, databases, and APIs
Comfort working with ambiguity and evolving requirements
Experience owning technical decisions without heavy process
Prior startup or founding-team experience strongly preferred
Base Salary: $150,000 – $190,000 (early-stage, San Francisco market)
Equity: Meaningful founding-level equity stake
Benefits: Health, dental, vision insurance; flexible PTO
Work Model: Hybrid or remote-friendly within U.S. time zones
