Crypta is an early‑stage startup looking to bring the gambling and trading worlds together with the first probability‑based decentralised exchange (DEX). We are building a platform that connects a fast‑paced gambling exchange, a Bitcoin lottery and a provably fair online crypto casino to an open Bitcoin liquidity pool that lets anyone be the house.
Instead of traditional order books or opaque casino odds, Crypta's exchange lets users trade highly volatile synthetic assets whose prices evolve from random cryptographic hashes rather than buy and sell orders. This makes the system provably fair and naturally resistant to market manipulation.
If you're excited by innovation, crypto, and building something genuinely new in the gambling/trading space, you'll fit right in.
About the Role
We're looking for a full‑stack developer who can comfortably own features end‑to‑end: from the React UI through to Node.js APIs and database design. You'll be the kind of person who is confident working across backend, frontend, and mobile layers.
You'll work closely with the founders to design and build:
The first fast‑paced gambling exchange where assets move based on cryptographic hashes
An innovative online crypto casino and Bitcoin lottery
Eventually converting the exchange into a decentralised exchange (DEX) on a public blockchain (Solana, Ethereum, Polygon etc.)
This is a hands‑on builder role in a small team. You'll have significant influence on architecture, tooling, and the overall product direction.
What you'll do:
Own features end‑to‑end
Design, implement, and ship new product features across front end and back end
Translate product requirements into technical specs and tasks
Front End (Typescript + React + Vite)
Build responsive, performant UI for casino games, trading markets, dashboards, and admin tools
Integrate with REST/JSON APIs and websockets for real‑time prices & game events
Implement reusable components, state management, and smooth UX flows
Build and maintain Node.js services for authentication, user balances, and game/exchange logic
Design and optimise PostgreSQL schemas, queries, and migrations
Integrate with blockchain services, payment providers, and third‑party APIs (where required)
Quality, Security & Reliability
Write tests and participate in code reviews
Use observability tools (logging, metrics, tracing) to monitor systems
Help design secure systems around wallets, deposits/withdrawals, and game fairness
Contribute to technical design for moving from CEX architecture to DEX (e.g. smart contracts, on‑chain order settlement, oracle integration)
Help identify parts of the system that should be on‑chain vs off‑chain
Work closely with founders, product and design
Help set standards and best practices from the ground up
Tooling: Git & GitHub, VSCode
What you'll need:
Please only apply if the following are true:
Full‑Stack Experience
You have built real products across both frontend and backend
React Framework with Vite builder
Strong experience building SPAs/frontends using React
Comfortable using build tools such as Vite
Experience building APIs/services in Node.js
Familiar with common backend patterns (routing, auth, validation, error handling)
Typescript for Frontend
Strong Typescript skills on the front end
Comfortable with types, interfaces, generics, and catching bugs at compile time
VSCode or similar IDE
Proficient with VSCode or a comparable modern IDE (debugging, extensions, formatting)
Confident using Git for version control, pull requests, branching, and code reviews
Comfortable working with a GitHub based workflow
Familiar with SQL (PostgreSQL)
Able to design tables, write queries, and understand indexes
Experience with PostgreSQL specifically is a strong plus
Gambling / Trading Platforms
Background in online betting, casino platforms, exchanges, or trading systems
Understanding odds, trading markets, and risk management concepts
Crypto / Web3
Experience integrating with blockchain networks, wallets, or smart contracts
Understanding of on‑chain vs off‑chain design, oracles, and general DeFi primitives
DevOps
Experience with CI/CD pipelines for builds, tests and deployments
Familiar with dockerised containers for packaging and deployment
Debugging techniques
Use of Chrome Devtools and attached debuggers for tracing and resolving bugs
Monorepo
Understanding of monorepo (Turborepo) structures for managing shared packages.
What we offer:
A competitive base salary + significant equity incentives will be offered for the right candidate
Fully remote or hybrid working arrangements
Flexible hours and outcome‑focused culture
Opportunity to innovate and shape the next wave of on‑chain gaming and DeFi
