Senior Full-Stack Engineer (Go) at Nahc.io – Hong Kong | Jobyssey

A proprietary trading and research firm is hiring experienced full-stack engineers to build the user interfaces and services behind mission-critical financial applications, including visual analytics platforms and data-driven tools used by traders, researchers, and analysts. You will work on TypeScript front-ends and the Go services that serve them as the team evolves its applications into a modular, plugin-based platform that other engineers build on. Expect to build reusable UI modules, component libraries, and SDKs as much as end-user features, and to own your work from structured product requirements through to production. No trading or finance background is required; the team cares about engineering craft and will teach you the domain.

What You'll Do

Collaborate with traders, researchers, and product managers to translate complex workflows into elegant UI solutions
Design and implement high-performance, responsive front-end applications using a current-generation TypeScript framework such as Svelte, React, or Vue
Design, build, and operate Go back-end services with security and performance built into their design, owning service boundaries and data contracts end-to-end
Build reusable UI modules, component libraries, and SDKs for a modular, plugin-based platform, and integrate front-ends through typed SDKs and MCP-based interfaces
Build real-time UIs that ingest and render high-frequency market and on-chain data from multiple streaming sources, using canvas-based charting (for example uPlot or TradingView Lightweight Charts) and D3.js for bespoke views
Drive architecture and performance decisions for modular, extensible systems, maintain automated tests and code review, and mentor other engineers on best practices

Core Essentials

7+ years hands-on full-stack development, with production ownership on both back-end and front-end
Strong, current TypeScript, HTML, and CSS with one or more modern front-end frameworks (Svelte, React, or Vue), and adaptability to work in a team's chosen framework
Strong, current Go experience, able to design, build, and operate production Go services independently
Proven experience handling large datasets and real-time updates from back-end sources such as WebSockets or Server-Sent Events, plus building reusable, well-structured UI components and shared abstractions
Strong grasp of performance optimization and rendering strategies in data-heavy applications, including the JavaScript runtime
Solid testing discipline, with unit and integration tests as a normal part of delivery
Excellent cross-functional communication, plus familiarity with a major cloud platform (AWS, GCP, or Azure) and version control

Bonus Skills

Background or strong interest in trading systems or financial platforms, including prior hedge fund or proprietary trading work
Experience with real-time, streaming, or on-chain / crypto market data
Experience with MCP (Model Context Protocol) or other AI-native / agent integration
Experience building developer platforms, SDKs, or shared component libraries, and with CI/CD, Docker, and observability tools such as Datadog, Grafana, or ELK
