Salary and Compensation

The official Berry role page on Y Combinator lists compensation as:

$50,000–$85,000 per year

0.10%–1.00% equity

This makes the role attractive for developers who want both salary and potential startup equity. The final offer may depend on experience, technical strength, interview performance, and how closely the candidate fits the company’s needs.

What the Role Involves

As a Founding Full Stack Engineer at Berry, the selected candidate will work closely with the founders and help build the company’s AI-powered SaaS product. This is not a narrow backend-only or frontend-only position. It is a full-stack role that may involve building product features, improving system architecture, working with AI-powered workflows, and shipping customer-facing tools.

The company says it is looking for a founding engineer to join an experienced team whose members have worked at major technology companies and startups, building systems used by large numbers of users.

Required Skills and Experience

Berry lists the role under Engineering, Full stack, with required skills including Python, TypeScript, and Machine Learning. The official YC job page also lists 6+ years of experience for the role.

Strong candidates should have:

Strong full-stack software development experience
Solid experience with Python and TypeScript
Ability to build clean, reliable, and scalable software
Interest in AI, LLMs, and applied AI products
Good product thinking
Strong communication skills
Ability to work independently in a small remote team
A strong drive to ship quality code

Berry states that applicants do not need to have worked with LLMs before, although it may be a plus. The company says it welcomes candidates from different backgrounds, as long as they have strong fundamentals and a willingness to learn.

Why This Job Stands Out

This role stands out because it is a founding engineering position. That means the selected developer may have more influence on technical decisions, product direction, and engineering culture than in a larger company.

Berry is also operating in the AI and SaaS space, which makes the role useful for developers who want to gain deeper experience in applied AI products. The company describes itself as a small, dynamic team building AI onboarding and customer success technology for SaaS companies worldwide.

Who Should Apply?

This role is best suited for experienced full-stack developers who want to work in an early-stage startup environment.

You may be a strong fit if you:

Have strong Python and TypeScript experience
Can work across frontend and backend
Enjoy building products from early stages
Want to work with AI-powered SaaS tools
Can communicate clearly in a remote team
Are comfortable taking ownership
Want a role where your work has direct product impact

Because this is a founding engineer role, candidates should be prepared for high ownership, fast execution, and close collaboration with the founders.

How to Apply

Interested candidates should apply through Berry’s official Y Combinator job listing.

Before applying, prepare:

Updated resume
LinkedIn profile
GitHub profile or portfolio
Examples of full-stack projects
Python and TypeScript project experience
Short explanation of your interest in AI or SaaS products
Any startup, product, or remote work experience

The Berry Founding Full Stack Engineer role is a strong global remote opportunity for experienced developers who want to work in AI, SaaS, and early-stage product development. With a listed salary of $50,000–$85,000 per year, equity between 0.10% and 1.00%, and remote hiring availability, the role may appeal to developers looking for more ownership than a traditional software engineering position.

For full-stack developers with strong Python, TypeScript, and product-building experience, this is a role worth considering.
