We give Entrepreneurs time back to focus on what they love doing - growing their business and being with customers. With a surging number of Entrepreneurs globally, we are innovating in a highly lucrative space.

    We operate 3 business segments:

    Corporate Secretary: Automating the company incorporation, secretarial, filing, Nominee Director, mailroom and immigration processes via custom online robots and SleekSign. We are the market leaders in Singapore with ~5% market share of all new business incorporations Accounting & Bookkeeping: Redefining what it means to do Accounting, Bookkeeping, Tax and Payroll thanks to our proprietary SleekBooks ledger, AI tools and exceptional customer service FinTech payments: Overcoming a key challenge for Entrepreneurs by offering digital banking services to new businesses Sleek launched in 2017 and now has around 15,000 customers across our offices in Singapore, Hong Kong, Australia and the UK. We have around 500 staff with an intact startup mindset. We have recently raised Series B financing off the back of >70% compound annual growth in Revenue over the last 5 years. Sleek has been recognised by The Financial Times, The Straits Times, Forbes and LinkedIn as one of the fastest growing companies in Asia. Backed by world-class investors, we are on track to be one of the few cash flow positive, tech-enabled unicorns based out of Singapore. We are looking for an SDET that is excited about the below Mission and Outcomes. Mission: At Sleek, we are on a mission to deliver intelligent, resilient, and high-performance software systems that transform user experiences across industries. We are seeking a SDET who is passionate about quality, automation, and architectural excellence to pioneer our next-generation test automation strategy. If you're eager to drive innovation in test engineering, collaborate cross-functionally, and lead the transformation of quality assurance in a complex, cloud-native, real-time environment, this is your calling.

    Outcomes:

    • Develop deep domain expertise by collaborating with squads and acquiring core business knowledge of Sleek to ensure meaningful and relevant test coverage.
    • Accelerate feedback loops by executing automated tests upon code commit to support a fail-fast engineering culture.
    • Ensure robust test coverage, maintaining over 80% automated test coverage for all features within the automation scope at all times.
    • Support strategic initiatives such as Sleek 2.0 by designing and implementing targeted automated test cases.
    • Improve issue resilience by adding negative validations or test scenarios for production issues within two weeks of occurrence.
    • Guarantee quality in critical flows, achieving 100% test coverage (happy and negative paths) for all business-critical journeys before each release.
    • Maintain test reliability with a 100% pass rate for automated test executions; proactively raise and resolve any failures.
    • Incorporate non-functional requirements into the automation suite, such as ensuring page load times remain under 3 seconds.
    • Promote a shift-left testing culture by enabling developers to independently maintain and initiate automated tests once developed.
    • Enhance visibility and reporting by improving the existing automation framework to support customized test execution reports mapped to source code.

    Optimise execution efficiency by ensuring tests run in parallel with a maximum execution time of 10 minutes per module and 30 minutes for the full regression suite. Minimise defect leakage, keeping it below 5% of the total defects identified during testing. To do this, you will have a minimum of 5 years experience in software development, and 1+ years in testing, with primary programming language being NodeJS.

    We're also looking for the following:

    • Deep experience with test automation frameworks (e.g., Selenium, Cypress, Playwright, TestNG, Robot Framework).
    • Proven success integrating test automation with CI/CD tools (e.g., Jenkins, GitHub Actions, GitLab CI, Azure DevOps).
    • Experience in microservices testing, API validation (e.g., Postman, REST-assured), and backend automation.
    • Familiarity with container orchestration tools (Docker, Kubernetes) and cloud platforms (AWS, Azure, GCP).
    • Hands-on knowledge of performance testing, security testing, and real-time streaming validation is a plus.
    • Strong understanding of software architecture, testing pyramid, and risk-based testing.
    • Strong debugging skills and ability to conduct root cause analysis on failures of both automation tests and code
    • Experience with AI/ML in testing and tools for visual/UX validation is a strong plus.
    • Excellent decision making skills, mentoring, problem-solving, and communication skills.
