Founding CTO Engineer (iOS-First, Mobile Builder)
About Solve
Solve, an AI-powered marketplace that connects people to real-world help instantly.
Finding someone reliable for small tasks today is slow and fragmented. Solve removes search entirely. Users post a need, and the system automatically matches them with the best person nearby based on availability, skills, and behavior.
The goal is to build the infrastructure layer for real-world task matching.
The Role
This is a Founding CTO / Founding Engineer role.
The responsibility is to build the product entirely from scratch, end-to-end.
This is a hands-on role. There is no team at the beginning. You will build the first version of the product independently.
A core requirement is the ability to build a mobile app from 0 (iOS first, ideally also Android/Google Play).
What You’ll Do
Build the iOS app from scratch (core priority)
Develop a mobile-first product
Build backend systems and APIs
Design and implement the real-time matching system
Implement:
Notifications and real-time updates
Payments and escrow system
User trust and reputation system
AI-based ranking and matching logic
Own all technical decisions (architecture, stack, infrastructure)
Ship fast and iterate continuously
Requirements
You have personally built and shipped mobile apps
You can build both mobile and backend systems
You are comfortable building alone in the early stage
Strong builder mindset: you execute, not just plan
Experience with iOS (Swift) or cross-platform mobile frameworks
Ability to operate in a 0→1 environment
High ownership and willingness to go all-in
Important:
This role requires hands-on mobile development. If you have not built mobile apps yourself, this is not a fit.
Commitment
Full-time
In-person in San Francisco during the early phase
First technical hire, building the initial product independently
Compensation
Equity-based at the beginning
Transition to salary after fundraising (pre-seed / seed)
Why This Role
Build the product from zero
Define product and technical direction
Large market with early validation signals
Applicants should be able to build and ship the first version of the product independently.
