Job Description

**Role Overview**

You’ll own core pieces of our product from Day 1. You’ll build consumer-grade

APIs. This is a high-ownership, high-intensity role working directly with the
founding team.

* Lead development across the frontend and backend.
* Integrate directly with leading DeFi protocols, aggregators, bridges, and data providers.
* Contribute across the stack (Node.js, Postgres) to ship features end-to-end.
* Operate with urgency and independence—identify problems, propose solutions, and execute.

**What We’re Looking For**

* Raw Intelligence & Drive — We hire for brains, grit, and commitment over pedigree. Ten years of mediocrity can’t beat raw talent and obsession.
* Proven Web3 Experience — 3–5+ years in crypto/Web3 (DEXs, wallets, aggregators), or exceptional proof of raw talent and curiosity.
* Crystal clear communication—no translators.
* Backend Brilliance — clean, secure, and scalable.
* Front-End Expertise — Next.js, React, TailwindCSS. You can build interfaces people love.
* Integration Mindset — You’ve connected sytems to crypto APIs, DeFi protocols, and aggregators.
* Full-Stack Ability — Comfortable in Node.js/TypeScript, Postgres.
* **Startup Killer DNA — Self-starter, thrives in chaos, relentless problem-solver.**

**Nice to Haves**

* Account abstraction (ERC-7702 smart wallets).
* Solana experience (Anchor, Web3.js).
* Deep knowledge of DEX/AMM mechanics, bridges, liquidity.
* Built products at scale (100k+ users).
* UI/UX sensibility.

**What to Expect**

* Ownership from Day 1 — You’ll own core parts of the product. **Don 't sit around waiting.**
* Direct Impact — Your code will shape how thousands interact with our platform.
* High-Performance Environment — Maniacal urgency, no fluff, no politics.
* Growth Potential — This role is a fast-track to technical leadership.
* Mission First Culture — We demand excellence. Camaraderie is secondary to winning.

**Our Tech Stack**

* Frontend: Next.js, React, TailwindCSS
* Backend: Node.js (TypeScript), REST/GraphQL, WebSockets, PostgreSQL, Redis
* Web3: Ethers.js, Viem, integrations with DEXs, aggregators, bridges, yield protocols
* Infra: Docker, Render, GitHub Actions, Cloudflare, PostHog

**Application Requirements**

* Links to live products you’ve built or contributed to (highlight your role).
* Evidence of Web3 integration work (code, screenshots, detailed writeups).
* A list of APIs, protocols, and platforms you’ve integrated with.
* (Optional) Design systems, UI libraries, or side projects that show your expertise.
