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

Confidential client — a Pre-seed startup (1-10 employees) building AI coworkers for IT teams: a security-focused product where an agent registers as a governed identity in a customer's directory, requests scoped access per task, escalates for human approval, and drives systems it was never given an API for. Raised a $6M seed round, backed by a strong bench of operator-angels from across IT and security. Several design partners today and a founding team of three. Full-Time, In-person, San Francisco, CA. Experience: 4+ years. Salary: $200,000-$300,000/yr. Visa sponsorship: H-1B, O-1, OPT.

About the Role: This is a backend- and systems-heavy founding engineering role where "full-stack" means owning the product and system end to end. You'll build the workflow engine for long-running human and agent work (durable state, retries, idempotency, approvals, replay, compensation, auditability), and design identity and authorization for humans, services, and agents (principals, delegation, scoped sessions, tenant isolation, traceable authority). You'll build a versioned policy engine for who or what can perform which action on which resource under what context; own secure storage and use of customer production keys, OAuth tokens, and admin credentials (isolation, rotation, ephemeral injection, revocation, blast-radius containment); own the boundary between probabilistic model behavior and deterministic execution (validation, evals, release gates); build isolated virtual environments and dev boxes for agents (reproducible state, observability, resource controls, safe teardown); and ship the interfaces and APIs to author, approve, inspect, debug, and operate these systems in production.

What You'll Own:

- The workflow engine for long-running human + agent work: durable state, retries, idempotency, approvals, replay, compensation, auditability

- Identity and authorization for humans, services, and agents: principals, delegation, scoped sessions, tenant isolation, traceable authority

- A versioned policy engine (who/what can do which action on which resource, under what context)

- Secure storage and use of customer keys, OAuth tokens, and admin credentials: isolation, rotation, ephemeral injection, revocation, blast-radius containment

- The probabilistic-to-deterministic execution boundary: validation, evals, release gates

- Isolated virtual environments and dev boxes for agents: reproducible state, observability, resource controls, safe teardown

Company stage: Pre-seed. Work type: In-person (San Francisco, CA).
