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

1. Partner with traders, researchers, and business stakeholders to turn complex workflows into effective products.
2. Own solutions end to end, from requirements and technical design through delivery, production support, and iteration.
3. Build high-performance React and TypeScript applications for real-time trading, analytics, and operational workflows.
4. Design, build, and operate production Go services, APIs, and backend integrations.
5. Develop robust real-time data flows and data-rich interfaces for large, frequently updating datasets.
6. Create reusable UI components, shared libraries, and extensible platform capabilities.
7. Drive architecture and performance decisions across frontend, backend, and data flows.
8. Ensure applications are reliable, maintainable, well tested, and observable in production.
9. Work in a fast-paced, collaborative environment with a high degree of ownership.

Requirements

1. 4+ years of professional full-stack software engineering experience, with clear production ownership across frontend and backend systems.
2. Strong production experience with Go/Golang.
3. Strong TypeScript, React, HTML, and CSS skills; experience with Svelte or Vue is also relevant.
4. Experience building responsive, data-intensive web applications with real-time updates.
5. Good understanding of WebSockets and/or Server-Sent Events.
6. Experience optimising frontend performance, including rendering, browser memory, and large-scale data handling.
7. Experience building reusable components, shared abstractions, SDKs, or platform capabilities.
8. Strong software design, testing, API design, and cloud-infrastructure fundamentals.
9. Excellent communication skills and the ability to work effectively with technical and non-technical users.
10. Comfortable working autonomously in a fast-moving environment.

Nice to Have

1. Experience with trading systems, market data, financial platforms, or other performance-critical software.
2. Exposure to event-driven systems, Kafka, Protobuf, relational or columnar databases, and microservice architectures.
3. Experience with data grids, charting, visualisation, or real-time dashboards.
4. Familiarity with Docker, CI/CD, observability tooling, and production operations.
5. Strong UI/UX judgement for dense, workflow-driven applications.
6. Experience using AI-assisted development tools responsibly in a production engineering environment.
