We’re reimagining how users interact with SaaS products and looking for a founding engineer to help build the first version from zero alongside a founder with experience building at HubSpot, Asana, and Datadog.

Role

We are hiring a Founding Engineer with strong frontend, product, and design instincts. You will work directly with the founder to shape the product, prototype quickly, make architecture decisions, think through user problems, and turn an early thesis into a working product.

The ideal person is a builder — someone who can move from an ambiguous idea to prototype, from prototype to usable product, and from usable product to scalable architecture. You should be excited by the opportunity to change how users interact with software and, eventually, the internet itself.

What You’ll Build

You will help build the first version of our core product, including:

- An SDK powered by frontier AI models and modern product experience protocols
- Backend services with rules, resolution logic and intent inference
- Early prototypes that help us test different wedges with customers
- Production-ready systems as the product direction becomes clearer

This role will likely span React, TypeScript, Next.js, backend APIs, databases, event tracking, and AI-assisted workflows.

Required Experience

- 2–5 years of software engineering experience, or equivalent demonstrated ability
- Strong frontend engineering experience with React and TypeScript
- Ability to design clean, scalable frontend component architecture
- Experience with backend APIs and databases
- Experience taking ambiguous product ideas and turning them into working software

Strong Plus

- Experience building 0-to-1 products
- Experience at an early-stage startup




- Experience building SaaS products

What Success Looks Like

In the first 30 days, you will:

- Understand our thesis, target customer, and product direction
- Help refine the first product wedge
- Build and iterate on early prototypes
- Set up core frontend and backend foundations
- Move quickly across product, design, and engineering decisions

In the first 60–90 days, you will:

- Ship the first usable product prototype
- Help build demo experiences that clearly communicate the product vision
- Create the first version of the adaptive frontend architecture
- Help test the product with early users, customers, or design partners
- Identify what should become production-grade versus what should remain experimental

Leadership Opportunity

This is a founding role with significant upside.

For the right person, robust performance can lead to a leadership position as the company grows. We are looking for someone who can become a long-term technical and product partner — someone who can help build the first version, shape the architecture, hire future engineers, and potentially lead major parts of the engineering organization.

This is an opportunity to join at the earliest stage and help define both the product and the company.

Why Join

- Build from zero with high ownership
- Work directly with the founder
- Help create a new category of software
- Own meaningful technical decisions from day one
- Opportunity to join the leadership team as the company scales

Skills:- React.js, TypeScript, NextJs (Next.js), frontend, backend, Software Testing (QA), Database Design, Software architecture, Systems architecture, Artificial Intelligence (AI), Machine Learning (ML), Product Management and Prototyping
