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?

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 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

Founding Full-Stack Engineer

On-site Engineering, Product & Tech Full time San Francisco, California, United States

Our client is a stealth, seed-stage startup building an AI-powered wearable platform for industrial field technicians - running a real-time computer-vision and agentic AI system directly on smart-glasses hardware, live today with major data-center, energy, and industrial customers across multiple countries. Backed by a $5M seed round and founded by researchers from Harvard/NASA (computer vision, published at NeurIPS and ICCV) and MIT (machine learning, ex-quant researcher).

The bet: computer vision and agentic vision-language models (VLMs) grounded in real integrations with legacy enterprise systems (ServiceNow, SAP, Salesforce) - not another LLM wrapper. The industrial data this generates is also laying the groundwork for robotics automation down the line.

As Founding Full-Stack Engineer, you'll own the product layer end-to-end: the real-time video/data pipeline connecting wearable hardware to the AI core under tight latency budgets and unreliable connectivity, the backend APIs and data layer, and the frontend/mobile client customers actually touch.

What you'll do
  • Build and own the real-time pipeline linking wearable hardware to the AI system
  • Design and ship backend APIs and the core data layer
  • Build the frontend/mobile client customers use daily
  • Work directly with the founding team in a small, high-ownership environment
Location & culture

Fully on-site in the SF Bay Area. The founding team lives and works together for the first several months in a shared house before moving to a standard office - expect an intense, in-person, roughly 9-9-6 pace. Hours flex for exceptional, senior talent; the priority is getting the right person, not saving on salary.

Requirements

Essential

  • 2-5 years shipping scalable production systems end-to-end, ideally at an early-stage startup
  • True full-stack range: backend/API/data layer AND frontend/mobile (React, React Native with native bridges)
  • Real-time/low-latency systems experience - either streaming platforms (e.g. Twitch, YouTube, Mux, Cloudflare, Agora, LiveKit) or hardware-constrained domains (drones, robotics, autonomous driving)
  • Some exposure to hardware-constrained/on-device work

Particularly valuable

  • Real-time video specifically
  • On-device/edge experience
  • Strong front-end/UX craft
  • Has shipped an AI/LLM/agent pipeline into production

Benefits

Compensation & benefits

    • Base: $180K-$240K
    • Equity: 0.25%-0.75%
    • Visa sponsorship available (O-1, TN, E-3, H-1B1, H-1B transfer, F-1 OPT/STEM OPT)

How to apply: submit your resume and a brief note on the most real-time/latency-sensitive system you've shipped.
