Job summary

SUMO Services Corporation is seeking a senior Test Engineer to lead and expand automated testing across our engineering stack in Metro Manila. You will own tests for high-risk financial data flows, build scalable test infrastructure, and act as a quality gatekeeper on pull requests while uplifting the team’s testing capabilities.

The role is hands-on and requires you to implement an end-to-end testing strategy, including a full CI/CD pipeline with GitHub Actions, and to mentor developers in

Qualifications

• 5+ years of software engineering or test engineering experience.
• Proven experience building or significantly expanding a CI/CD pipeline, ideally with GitHub Actions.
• Strong experience with integration testing (e.g., containerized test environments such as Testcontainers) and end-to-end testing tools (Playwright, Cypress, or similar).
• Comfortable reading and writing code in our stack: [Backend language/framework], [Frontend framework]
• Track record of growing and scaling automated testing practices on an engineering team.
• Strong communication and mentoring skills — you'll be reviewing others' work and teaching, not just writing tests solo.

Responsibilities

• Design and implement our CI/CD pipeline using GitHub Actions, including branch protection so tests must pass before merge
• Build integration and end-to-end test infrastructure (e.g., Testcontainers, Playwright or Cypress)
• Write and maintain automated tests for our most critical business flows, including approval workflows and financial/accounting data exports
• Define and enforce testing standards across the team, including deliberate failure-path and fault-injection testing
• Review pull requests for test coverage and quality on critical systems
• Establish and maintain a regression suite, plus smoke tests for post-deployment sanity checks
• Mentor our engineering team on writing effective unit, integration, and end-to-end tests
• Introduce security and performance/load testing as the team matures
• Report on testing health and coverage to engineering leadership

Job description

Job Overview

We're a growing engineering team looking for our first dedicated Test Engineer to lead and expand our automated testing practice. We already have some automated testing in place (for example, regression testing for data extraction), and we're looking for someone to build on that foundation: extending coverage to integration and end-to-end testing, standing up a full CI/CD pipeline, and raising testing standards across the team. This is a hands-on, senior-level role — you won't just coach from the sidelines. You'll write and own tests for our highest-risk systems (including financial/accounting data flows), build integration and end-to-end testing infrastructure, and act as a quality gatekeeper on pull requests, while raising the testing skills of the wider team.

This is a senior, hands-on role for someone with strong engineering experience who has built out testing practices and infrastructure before, and who is comfortable being both an individual contributor and a mentor.

How You'll Spend Your Time (approximate, evolves over time)

• 35% — Writing and owning tests directly for our highest-risk areas (approval workflows, accounting/financial data exports)




• 25% — Reviewing pull requests and gatekeeping test quality, especially for critical flows




• 20% — Regression testing, smoke testing, and release-level checks — expanding our existing regression coverage (currently focused on data extraction) to more areas of the system




• 20% — Coaching developers and building shared infrastructure: CI/CD pipeline, test frameworks, standards, and checklists

Key Responsibilities

• Design and implement our CI/CD pipeline using GitHub Actions, including branch protection so tests must pass before merge




• Build integration and end-to-end test infrastructure (e.g., Testcontainers, Playwright or Cypress)




• Write and maintain automated tests for our most critical business flows, including approval workflows and financial/accounting data exports




• Define and enforce testing standards across the team, including deliberate failure-path and fault-injection testing




• Review pull requests for test coverage and quality on critical systems




• Establish and maintain a regression suite, plus smoke tests for post-deployment sanity checks




• Mentor our engineering team on writing effective unit, integration, and end-to-end tests




• Introduce security and performance/load testing as the team matures




• Report on testing health and coverage to engineering leadership

Requirements

• 5+ years of software engineering or test engineering experience, with significant hands-on automated testing work




• Proven experience building or significantly expanding a CI/CD pipeline, ideally with GitHub Actions




• Strong experience with integration testing (e.g., containerized test environments such as Testcontainers) and end-to-end testing tools (Playwright, Cypress, or similar)




• Comfortable reading and writing code in our stack: [Backend language/framework], [Frontend framework]




• Track record of growing and scaling automated testing practices on an engineering team




• Strong communication and mentoring skills — you'll be reviewing others' work and teaching, not just writing tests solo




• Experience testing systems handling sensitive or financial data is a strong plus

Nice to Have

• Experience with security testing or performance/load testing




• Experience in fintech, accounting software, or another regulated/high-stakes data domain




• Familiarity with contract testing for service-to-service integrations
