Staff Software Development Engineer in Test (SDET)

About Us

We’re building the next generation of urban mobility in Southeast Asia. Our car-sharing platform connects drivers with vehicles seamlessly, managing complex logistics, real-time tracking, payments, and user experiences at scale.

We are a lean, fast-moving engineering team that ships features users rely on daily.

Role Overview

As a Staff SDET, you will own the quality and test automation strategy across our entire product ecosystem — including mobile applications (iOS & Android), web platforms, and backend APIs.

You will serve as the hands-on technical authority for testing, responsible for designing automation frameworks, integrating them into CI/CD pipelines, and continuously raising the engineering quality bar.

This is an individual contributor (IC) role. You will lead through technical excellence and automation-first thinking.

Key Responsibilities

• Design and build a scalable test automation platform (frameworks, tooling, test data, reporting)
• Develop and maintain automated test suites across UI (mobile & web), API, integration, and performance layers

• Own end-to-end QA strategy across mobile, web, and backend systems
• Define and enforce quality standards, testing processes, and release criteria
• Champion a strong quality culture and promote shift-left testing practices

• Integrate automated testing into CI/CD pipelines for fast and reliable deployments
• Support continuous delivery with high confidence in releases

• Design and execute performance and load testing strategies to ensure scalability
• Identify, troubleshoot, and resolve quality issues through root cause analysis

• Work closely with engineering teams to resolve defects and improve product quality
• Communicate risks, trade-offs, and recommendations clearly to stakeholders
• Perform exploratory and end-to-end testing, including real-world scenarios where applicable

• Minimum 8 years of experience in software testing, automation, or quality engineering
• Strong expertise in white-box, grey-box, and black-box testing
• Proficient in at least one programming language (preferably JavaScript/TypeScript)

• Web automation frameworks (e.g. Playwright, Cypress, WebdriverIO)
• Mobile automation tools (e.g. Appium, Detox, Maestro, XCUITest, Espresso)
• API testing (REST, GraphQL)
• CI/CD tools (e.g. GitHub Actions, CircleCI, Fastlane)

• Experience building QA automation platforms from scratch
• Strong understanding of QA strategy (balancing coverage, speed, and cost)
• Familiar with Agile methodologies (Scrum, TDD, BDD)
• Excellent communication skills with both technical and non-technical stakeholders

• Experience in security testing and penetration testing
• Familiarity with code quality tools (e.g. SonarQube, ESLint)
• Performance testing tools (e.g. k6, JMeter, Gatling)
• Observability tools (e.g. Datadog, Grafana, Sentry)
• Valid driving licence (for real-world testing scenarios)
• Additional language proficiency beyond English

• Greenfield opportunity — build the entire QA automation platform from scratch
• High impact role — directly improve reliability of thousands of daily car-sharing trips
• Lean team environment — low bureaucracy, fast decision-making
• Hands-on work (80–90%) — focus on coding, building, and problem-solving
• Collaborative culture — high trust, strong engineering team
• Competitive salary package with flexible work arrangements and professional development support
