About the Company

We are a next-generation cryptocurrency exchange focused on building innovative and secure trading experiences for digital assets and derivatives. With a strong emphasis on perpetual trading and real-time market execution, we aim to redefine how traders interact with crypto markets — combining transparency, performance, and user-centric design.

Role Overview

We are seeking a Full Stack Developer experienced in perpetual trading platforms and Web3 ecosystems. The ideal candidate should have hands-on experience working with both frontend (React/Next.js) and backend (Node.js/Nest.js) systems and integrating decentralized perpetual trading APIs such as GMX, Hyperliquid, or similar. You will build end-to-end high-performance trading modules, ensuring low-latency execution, real-time data sync, and seamless user interaction.

Key Responsibilities

• Design, develop, and maintain full-stack trading modules and dashboards for perpetual and derivatives trading.
• Integrate decentralized perpetual trading APIs (GMX, Hyperliquid, Drift, etc.) and Web3 wallets (MetaMask, WalletConnect).
• Implement real-time order books, market data feeds, and trade execution flows using REST and WebSocket APIs.
• Build scalable backend services using Node.js / Nest.js / Express and connect them to the frontend.
• Manage database operations for user data, trade history, and performance analytics.
• Collaborate with UI/UX, blockchain, and DevOps teams to deliver high-performance trading experiences.
• Optimize both frontend and backend for speed, security, and low latency.
• Write clean, maintainable, and modular code following modern development practices and standards.

Required Skills & Experience

• 3+ years of experience as a Full Stack Developer, preferably in crypto, DeFi, or trading platforms.
• Strong proficiency in React.js / Next.js, Node.js / Nest.js / Express, and TypeScript / JavaScript (ES6+).
• Proven experience integrating perpetual trading or DeFi APIs (GMX, Hyperliquid, Drift, etc.).
• Experience with WebSockets for live order books and trade updates.
• Understanding of Perpetual Trading, Futures, and DeFi trading mechanics.
• Hands-on experience with Web3 libraries (ethers.js, web3.js) for wallet and smart contract integration.
• Strong understanding of RESTful APIs, microservices, and database management (PostgreSQL, MongoDB, or similar).
• Familiarity with security best practices, API rate limiting, and user authentication (JWT/OAuth).

We’re seeking a highly skilled, hands-on Product Engineer with strong end-to-end product development experience - from concept (0→1) through iterative launch and scaling. You’ll own features across the stack (frontend, backend, infra), with a strong sense of UX, design quality, and user empathy.

The ideal candidate has shipped real products publicly on Product Hunt, App Store, or live web platforms and can demonstrate thoughtful product decisions, iteration, and measurable user impact. You’ll work in a lean, high-velocity pod alongside ML and DevOps specialists, contributing not just code but direction, polish, and execution. This is a role for builders who thrive on accountability, autonomy, and the craft of taking products live.

Responsibilities:

• Full-Stack Product Ownership: Design, build, and ship features end-to-end - from concept to deployment - ensuring smooth, performant, and polished user experiences.
• Frontend & UX Craft: Implement high-quality, responsive, and performant interfaces. Own details like animations, progress indicators, and state management for media-heavy workflows.
• Backend & Infrastructure: Build robust APIs, real-time features, and integrations with ML pipelines. Ensure reliability, scalability, and maintainability.
• Media & Streaming Systems: Develop performant video workflows, upload/processing flows, streaming, and playback experiences with real-time progress tracking.
• AI/ML Integration: Collaborate with MLOps engineers to integrate and productionize ML features, handling data flows, inference endpoints, and user-facing AI interactions.
• DevOps & CI/CD: Manage efficient deployments using modern cloud tooling (preferably GCP) and maintain CI/CD pipelines for rapid iteration.
• Product Thinking & Iteration: Drive decisions grounded in user feedback and metrics. Balance trade-offs between polish, speed, and scalability.
• Collaboration & Initiative: Work closely with designers and specialists, proactively proposing improvements and solutions rather than just surfacing blockers.

Requirements

• Experience: Proven record of shipping live products (preferably 3+ years in product-focused engineering).
• Portfolio Evidence: Links to real products, public launches, or active projects (Product Hunt, GitHub, App Store, live demos).
• Full-Stack Skills: Proficient in modern frontend frameworks (Next.js, Firebase Storage SDK, React Query) and backend environments (NestJS, TypeORM, PostgreSQL).
• Media/Video Expertise: Experience with streaming, video processing, encoding, or real-time rendering systems.
• Cloud & CI/CD: Familiar with GCP, containerized deployments (Docker/Kubernetes), and automated pipelines.
• AI/ML Exposure: Comfortable integrating ML models or AI APIs into production features.
• Execution Mindset: Bias toward action, accountability, and high ownership of outcomes.
• Product Sense: Demonstrated ability to think from a user’s perspective — balancing technical feasibility with product value.

Benefits

• Best in class salary: We hire only the best, and we pay accordingly.
• Proximity Talks: Meet other designers, engineers, and product geeks — and learn from experts in the field.
• Keep on learning with a world-class team: Work with the best in the field, challenge yourself constantly, and learn something new every day.
