Software Development Engineer in Test (SDET)

Job Responsibilities:

• Develop, implement, and maintain distributed stress test / load test / performance test scripts written in NodeJS (JavaScript) / Rust against HTTP APIs, WebSockets, and gRPC services.
• Execute distributed stress tests, analyse and compile results, and communicate findings to product managers, development teams, and DevOps teams to support release and capacity decisions.
• Investigate stress and load test outcomes — throughput limits, latency degradation, error rates, and resource saturation — and work with development and DevOps teams to pinpoint root cause and validate fixes.
• Develop, implement, and maintain the QA team's automated testing platform, spanning backend services and frontend dashboards — covering test case orchestration, scheduling, distributed execution, and result reporting.
• Build and maintain automated test suites for web and mobile applications using Playwright, Appium, CDP, and ADB, including real-device execution.
• Develop, implement, and maintain small/medium-scale automation projects on an on-demand basis.

Job Requirements

• Bachelor's in Computer Science, Software Engineering, or equivalent
• 1+ year of hands-on experience in software automation, SDET, or QA engineering
• Strong programming skills and coding knowledge in automation
• Proficient in JavaScript (NodeJS) and Python3
• Working knowledge of HTTP APIs, WebSockets, gRPC, MongoDB, and ReactJS
• Experience with Rust and Redis; Playwright, Appium, CDP, or ADB is an advantage
• Excellent analytical and problem-solving skills, with a methodical approach to debugging
• Fantastic communication and presentation abilities
• Required Language(s): English, Mandarin (candidate needs to liaise with Mandarin-speaking counterparts)
• Candidates with EQUIVALENT technical skills are ENCOURAGED to apply

How this career will benefit you:

This is a permanent role with a clear growth path into Senior QA engineering, SDET, or performance engineering specialisation.

• Breadth beyond typical QA. You won't just write test scripts — you'll build and own the tooling and platforms the QA team runs on, spanning backend services, frontend dashboards, and device automation. You leave with real software engineering experience, not just testing experience.
• Work at scale. Design and run distributed stress and load tests against production-grade systems, and get direct exposure to how large systems actually behave under pressure — the kind of insight most engineers don't get until much later in their career.
• Modern, in-demand stack. Hands-on with NodeJS, Python3, Rust, ReactJS, MongoDB, Redis, HTTP/WebSocket/gRPC APIs, plus real-device automation (Appium, Playwright, CDP, ADB) and cloud infrastructure.
• AI-assisted automation. Work on the emerging edge of QA — LLM-driven test analysis, self-healing test execution, and intelligent failure diagnosis.
• Real ownership and visibility. You'll present findings directly to product managers, development, and DevOps teams. Your analysis influences release and capacity decisions, so your work is seen and it matters.

Benefits of this role:

• Permanent, full-time position
• 13th Month Salary (upon Company Declaration)
• Project Incentive (upon Company Declaration based on project performance)
• Fixed Allowance (upon Confirmation)
