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.

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.

Full-time

Re-posted 10 days ago


Job description

The Opportunity

EQL Tech is recruiting for a founding role within a venture-backed startup building the financial infrastructure for the future of education. Our client is developing the rails that allow families to access State education funds (ESAs), unlocking a $900B US Public Education budget. With $16M raised from top-tier VCs, the team is composed of elite engineers and specialists from Stripe, SpaceX, and Goldman Sachs.

The Role

As the Full Stack Lead, you will own the parent-facing mobile and web experiences from inception to launch.

  • End-to-End Ownership: Lead the reimbursements product across mobile (receipt capture, claims) and web (statementing).
  • System Design: Build for clarity and trust, ensuring families are never confused about eligibility or fund status.
  • Operational Integration: Tightly link the UI with backend and ops workflows to create a reliable payments machine with clean audit trails.
  • Data-Driven Growth: Instrument funnels and "confusion hotspots" to turn user behavior data into product improvements.
  • Setting Standards: Establish the architecture, code quality, and release processes for the app layer.

Requirements

To be successful in this founding role, you must meet the following criteria:

  • Relocation/Presence: You are willing to relocate to San Francisco, CA or Phoenix, AZ and work in-person with the team.
  • Proven Shipping Velocity: you have a history of shipping apps constantly to production, including personal side projects.
  • Technical Detail: You take pride in refining design and architecture to improve the user experience.
  • Product Intuition: You have a strong "taste" for intuitive AI and pay close attention to the psychology of features.
  • Collaborative Nature: You are willing to get "out of localhost" to engage in family visits and collaborate with government agencies.
  • High Standards: You have high expectations for yourself and a deep commitment to the quality of your work.

Benefits

Commitment, Compensation & Benefits

This will be a big commitment, and we're aiming high. It needs to be something you are energised about taking on, or this isn't the team for you.

  • Competitive Salary: $125,000 - $175,000 per year, commensurate with experience.
  • Generous Founding Equity: We compensate you well with equity.
  • Top-Tier Backing: We've raised $16M from top-tier VCs and angels.
  • Relocation Support: You are willing to relocate to San Francisco, CA, or Phoenix, AZ, and travel to visit customers. We're an in-person company and are in the office together.
  • Comprehensive Visa Sponsorship: If you do not have a visa, we can support you.
  • Unmatched Impact: The rare opportunity to directly shape how the $900B US Public Education budget is being opened up for parents to take control of their portion (avg. $7.5k/kid/year).
