Senior Full-Stack Realtime Software Engineer (Trading / Web3 / Performance)

APEING is building the social execution layer of DeFi, combining real-time trading, , social narrative, and high-performance market infrastructure into one platform.

We are building for speed, scale, and user experience. Our core product includes real-time DEX data, meme markets, launchpads, fast terminal interactions. We are looking for a highly capable engineer who can help us build a product that feels instant, polished, and category-defining.

We're hiring a Senior Full-Stack Realtime Engineer to help architect and optimize the parts of the product that matter most to users:

• fast rendering

• real-time data flow

• low-latency frontend interactions

• memory efficiency

• streaming market data

• scalable full-stack architecture

This is not a generic full-stack role. We want someone who understands how to build systems that feel more like a trading terminal, gaming product, or high-performance realtime app than a traditional SaaS dashboard.

You should be comfortable owning performance across both frontend and backend layers.

What You'll Work On

Optimize rendering performance across terminal, charts, watchlists, meme pages, and launchpad flows

Improve memory usage and eliminate client-side performance bottlenecks

Architect scalable real-time data pipelines for frequently updating DEX / trading data

Design efficient WebSocket / subscription systems for live market data

Improve lazy loading, virtualization, pagination, and large dataset handling

Work closely with frontend and backend engineers to ensure clean data contracts and low-friction UX

Help make the app feel instant, responsive, and stable across desktop and mobile/PWA environments

Contribute to production architecture decisions around scale, caching, realtime updates, and user experience

What We're Looking For

5+ years of experience as a software engineer

• Strong full-stack experience with TypeScript / JavaScript

• Strong frontend experience with React / Next.js

• Strong backend experience building scalable APIs, websocket systems, or realtime services, Rust

Experience working on realtime products, such as:

• trading apps

• market data platforms

• gaming products

• live dashboards

• forex / crypto terminals

• betting or streaming products

• Deep understanding of:

• rendering optimization

• memory leaks / memory management

• large dataset performance

• lazy loading / virtualization

• websocket architecture

• caching / batching / throttling

• High ownership and ability to move fast in a startup environment

• Strong Plus If You Have

• Web3 / crypto product experience

• DEX, trading, or market data platform experience

• Experience with charting libraries and live updating interfaces

• Mobile web / PWA optimization experience

• Experience with Redis, Kafka, ClickHouse, or similar realtime data infrastructure

• Familiarity with Solana / DeFi ecosystems

What Success Looks Like:

• The platform feels fast, clean, and responsive under heavy live data load

• Users can navigate the terminal, memes page, launchpad, and live rooms without lag or friction

• Data updates feel realtime without breaking UI performance

• The system is built in a way that scales as product usage grows
