Senior Full-Stack Engineer (Golang / React) - Tier 1 Buyside Firm – Remote (APAC)

Location: Hong Kong, Singapore, Australia

Are you interested in working closely with researchers and traders in a buyside firm?

My client is seeking a Senior Full-Stack Engineer to build and own mission-critical trading and analytics applications used daily by traders, researchers, and analysts.

You will work directly with end users to understand complex workflows and deliver intuitive, high-performance products. This is a genuinely full-stack role: designing responsive, data-intensive React applications; building the Go services and real-time APIs behind them; and taking systems through to reliable production operation.

The applications are real-time and performance-sensitive, where accuracy, responsiveness, and reliability directly matter to the business. Prior trading experience is not essential; strong engineering fundamentals, product ownership, and an interest in solving challenging technical problems are.

Responsibilities

• Partner with traders, researchers, and business stakeholders to turn complex workflows into effective products.

• Own solutions end to end, from requirements and technical design through delivery, production support, and iteration.

• Build high-performance React and TypeScript applications for real-time trading, analytics, and operational workflows.

• Design, build, and operate production Go services, APIs, and backend integrations.

• Develop robust real-time data flows and data-rich interfaces for large, frequently updating datasets.

• Create reusable UI components, shared libraries, and extensible platform capabilities.

• Drive architecture and performance decisions across frontend, backend, and data flows.

• Ensure applications are reliable, maintainable, well tested, and observable in production.

• Work in a fast-paced, collaborative environment with a high degree of ownership.

Requirements

• 4+ years of professional full-stack software engineering experience, with clear production ownership across frontend and backend systems.

• Strong production experience with Go/Golang.

• Strong TypeScript, React, HTML, and CSS skills; experience with Svelte or Vue is also relevant.

• Experience building responsive, data-intensive web applications with real-time updates.

• Good understanding of WebSockets and/or Server-Sent Events.

• Experience optimising frontend performance, including rendering, browser memory, and large-scale data handling.

• Experience building reusable components, shared abstractions, SDKs, or platform capabilities.

• Strong software design, testing, API design, and cloud-infrastructure fundamentals.

• Excellent communication skills and the ability to work effectively with technical and non-technical users.

• Comfortable working autonomously in a fast-moving environment.

Nice to Have

• Experience with trading systems, market data, financial platforms, or other performance-critical software.

• Exposure to event-driven systems, Kafka, Protobuf, relational or columnar databases, and microservice architectures.

• Experience with data grids, charting, visualisation, or real-time dashboards.

• Familiarity with Docker, CI/CD, observability tooling, and production operations.

• Strong UI/UX judgement for dense, workflow-driven applications.

• Experience using AI-assisted development tools responsibly in a production engineering environment.
