Industry: Technology, Information and Media
Seniority level: Associate level
Salary range:
$150K - $210K &
0.50 % -
1.00 % equity Experience: 1-4+ YoE ₹1,50,000 - ₹2,10,000 a year
We’re building
self-improving software
— AI that continuously creates, tests, and optimizes in-app experiences without human intervention. Our mission is to
automate the entire lifecycle of product experimentation , starting with onboarding for consumer apps and expanding to every stage of the user journey.
We already power experiences for
some of the world’s largest and fastest-growing consumer apps , serving millions of users daily. Backed by
Y Combinator ,
Gradient Ventures , and leaders from
Uber, OpenAI, Meta , and more, we’ve raised
$5M+
to bring this vision to life.
This is an opportunity to
build foundational systems
at the intersection of AI, personalization, and massive-scale product delivery.
The Role
As a
Founding Full-Stack Engineer , you’ll design and ship AI-driven features that reach millions of users — working directly with the founders and owning your work from idea to deployment. You’ll move fast, experiment aggressively, and see your work in production within days, not months.
Location:
San Francisco (in-person, Mon–Sat)
Eligibility:
US work authorization required (O-1 visa sponsorship available for exceptional candidates)
What You’ll Do
Build an
AI-powered paywall editor
used by millions — spanning a high-performance Python backend and a modern
Next.js
front-end
Integrate cutting-edge AI models, APIs, and tools to power real-time personalization and automated experimentation
Architect backend services in Python capable of handling
thousands of global requests per second
Collaborate with founders, customers, and designers to shape product direction and deliver high-impact features
Contribute across the stack — from data pipelines to frontend UI to deployment automation
Help define engineering culture, processes, and technical standards for the team
What We’re Looking For
1–4+ years
of engineering experience shipping real-world products
Strong
full-stack expertise
— Python on the backend, React/ Next.js
on the frontend
Proven ability to
turn ambiguous problems into shipped features
Experience building
user-facing products
and collaborating directly with customers
Comfort owning features
end-to-end
— from design to deployment
Strong communication skills and a collaborative, problem-solving mindset
Bonus Points
Experience integrating
AI/ML/LLMs
into production products
Background with
design tools, chat interfaces, or creative coding
Prior
startup or founding team
experience
Mobile development skills ( Swift, Flutter, Expo )
Tech Stack
Frontend:
Next.js
(React/TypeScript), Zustand, Tailwind/Shadcn
Backend:
Python,
Fly.io , Supabase
Mobile:
Swift, Flutter, Expo
Some Challenges You’ll Work On
AI-driven personalization
using reinforcement learning — dynamically optimizing prices, paywalls, and onboarding flows
Autonomous experimentation
— building systems that generate and run A/B tests automatically
Scalable content delivery
— backend services that serve AI-generated experiences to millions of devices with sub-second latency
Mobile webview optimization
— delivering native-like performance across multiple stacks
Why You’ll Love It Here
Founder-level impact:
Every decision you make shapes the product, tech stack, and company direction
Immediate scale:
Your work will be in the hands of millions of users right away
Cutting-edge AI:
You’ll work directly with frontier AI models and emerging technologies
High ownership:
Small team, massive responsibility, zero bureaucracy
Career-defining opportunity:
This is the ground floor of something industry-defining #J-18808-Ljbffr
