Founding Full Stack Engineer information

What is a Founding Full Stack Engineer?

A Founding Full Stack Engineer is an early, core technical team member at a startup who is responsible for building both the front-end and back-end of the company's product. This role goes beyond typical engineering, often involving product decisions, architecture design, and collaborating directly with the founders. Founding Full Stack Engineers help shape the company's culture, technical direction, and can have significant equity stake. Their work is crucial in taking the business from idea to launch, often in a fast-paced, resource-limited environment.

What are the key skills and qualifications needed to thrive as a Founding Full Stack Engineer, and why are they important?

To thrive as a Founding Full Stack Engineer, you need expertise in both front-end and back-end development, deep knowledge of programming languages like JavaScript, Python, or Ruby, and experience with scalable architectures, often backed by a degree in computer science or equivalent experience. Familiarity with frameworks (React, Node.js, Django), version control systems (Git), cloud platforms (AWS, GCP), and DevOps practices is typically required. Strong problem-solving, initiative, adaptability, and excellent communication distinguish successful candidates, enabling effective collaboration in a startup environment. These skills and qualities are crucial for building robust products rapidly and influencing the company's technical direction from its early stages.

What is the difference between Founding Full Stack Engineer vs Full Stack Engineer?

AspectFounding Full Stack EngineerFull Stack Engineer
CredentialsTypically requires proven full stack development experience, sometimes with startup or early-stage company involvementRequires relevant full stack development skills, often with formal education or certifications
Work EnvironmentEarly-stage startups or founding teams, often wearing multiple hatsEstablished companies or startups, focused on project delivery
Employer & Industry UsageFounding teams, startups, tech entrepreneursTech companies, agencies, startups, corporate IT teams

Founding Full Stack Engineers are key players in early-stage startups, often involved in building core products from scratch and shaping company technology. Full Stack Engineers work across various company sizes, focusing on developing and maintaining applications. The main difference lies in the startup environment and level of involvement in founding the company.

What unique challenges might a Founding Full Stack Engineer face when joining an early-stage startup?

As a Founding Full Stack Engineer at an early-stage startup, you'll often balance building core product features with setting up foundational technical infrastructure. This role typically requires wearing multiple hats, from architecting systems and writing code to making critical technology decisions and collaborating closely with non-technical founders. You may encounter challenges such as ambiguous requirements, shifting priorities, and limited resources, but you'll also have significant influence over the company's technical direction. The dynamic environment encourages rapid learning and offers accelerated career growth, particularly for those who thrive in fast-paced, collaborative settings.

Job description

Job Title: Founding Full-Stack Engineer
Job Duration: Full-time
Job Location: New York City, NY & San Francsico, CA
Work Arrangement: Onsite
 
About the Role
  • We’re looking for a Founding Engineer to build and scale our company with us. You'll be responsible for helping build a product from 0 to 1. As a founding engineer, you’ll be doing it all — integrating orchestrating tool-calling agents, scaling data infrastructure across GCP and building a full-stack web application from scratch. The ideal candidate has strong full-stack experience and is deeply interested in building a company with high-caliber teammates from the ground up. This role is not easy but is deeply rewarding. It is ideal for ambitious engineers who want to start their own companies someday or want to take on leadership roles.
 
What You'll Do
  • Work closely with product and frontend teams to align on integration logic and data modeling.
  • Build and deploy LLM-based agents using GCP infrastructure
  • Design and evolve scalable relational data models for complex medical and operational data.
  • Work across a dual backend stack:
  1. NestJS (TypeORM, Swagger, Supabase, Vercel AI SDK)
  2. FastAPI (Pydantic, uvicorn, OpenRouter integration)
  • Develop and maintain tool-calling orchestration libraries and context assembly pipelines
  • Design and orchestrate data pipelines using GCP services to transform, move, and expose data efficiently.
  • Implement and evolve Model Context Protocol (MCP) compliant clients and servers
  • Optimize memory, latency, and cost of streaming prompt pipelines
  • Connect core data infrastructure to APIs that serve both frontend and AI consumption needs.
  • Build and maintain clean, modular, and reusable components.
  • Own the full lifecycle of features: from Figma translation to production deployment.
  • Implement responsive design patterns with strong breakpoint awareness (mobile/desktop).
  • Work in a Cursor-based dev environment and promote best practices for collaboration.
  • Integrate and maintain 3rd-party APIs and SDKs into our backend services.
  • Build internal API wrappers and tools to standardize and scale integrations.
  • Develop secure, efficient, type-safe RESTful APIs that expose integrated data to our frontend and AI layers.
 
Tech Stack:
  • GCP: Vertex AI, LLM
  • Infra: OpenRouter, AI Vercel SDK, tool-calling libraries (LangChain, custom), MCP clients/servers
  • Backend: Python, TypeScript
  • Frontend: React, Next.js (App Router), Tailwind CSS, TanStack Query (React Query), Vercel SDK
