About Timo

Launched in 2015, Timo pioneered digital banking in Vietnam with a mission to make banking faster, simpler, and more accessible.

Today, as part of one of Southeast Asia’s leading digital financial services platforms, Timo is building secure, scalable, and customer-first digital banking experiences for millions of users across Vietnam.

We are looking for curious minds and driven talents from fintech, digital banking, and technology companies who are excited to move fast, build meaningful products, and help shape the future of banking in Vietnam.

About the Role

We are looking for a Senior Software Engineer in Test (SDET) to help shape and drive Timo's test automation strategy across mobile, backend, and integration layers.

You will own the design, build, and continuous improvement of our automation frameworks — partnering closely with Engineering, QA, and DevOps to raise the bar on release confidence, system reliability, and overall product quality. Beyond writing tests, you will define how Timo tests at scale and mentor others to do the same.

You will report to QA Lead.

What You Will Do

Define and own Timo's test automation strategy across mobile apps, backend services, and integrations
Design and build scalable, reusable automation frameworks across UI, API, integration, and data layers
Identify high-risk areas and critical user journeys, and ensure they have proper automated coverage
Integrate automated tests into CI/CD pipelines (Jenkins, GitLab CI) to enable continuous testing
Analyze test results and drive quality improvements, close coverage gaps proactively
Collaborate with Engineering, QA, and DevOps to improve system reliability and release confidence
Mentor team members through code reviews, pairing, and knowledge sharing
Continuously improve testing processes, frameworks, and tooling

\n\n## Your skills and experience\n\n

What We Are Looking For

5+ years in test automation, with strong hands-on experience designing automation solutions
Proven experience testing across multiple layers: UI, API, and system integration
Comfortable working in agile, cross-functional product teams

Strong programming skills
Hands-on with automation tools/frameworks: Selenium, Appium, Playwright, Robot Framework, or equivalent
Solid understanding of test automation strategy: test pyramid, risk-based testing, and the boundaries between unit, API, and E2E testing
Experience integrating tests into CI/CD pipelines: Jenkins, GitLab CI, or similar
Experience with version control (Git) and modern development workflows
Strong debugging, analytical, and problem-solving skills
Professional working English: daily collaboration with Timo leadership and Kredivo's regional teams

\n\n## Why you'll love working here\n\n

Our deliverable is a leading software that is changing the way people do banking. You will be proud of your work and you will share with everybody that you helped to build Timo.

You’ll be joining a team of experts who are technically savvy, creative, and who share the intention of reinventing banking in Vietnam. You work closely with international architects and front-end consultants, product managers, and designers to develop the system. You will learn a lot from them.
