We’re looking for a seasoned Senior Full Stack Engineer with 6-7 years of hands-on experience to join our engineering squad. You will be responsible for maintaining and optimizing a high-traffic hi-tech application used by thousands of users.
· Mobile Ecosystem Expert: You will own the stability and performance of the React Native mobile application, ensuring that native features, cross-platform components, and mobile-specific integrations function flawlessly for a global user base.
· Surgical Precision: You will dive into a complex Ruby on Rails and React ecosystem to resolve high-priority "Break-fix" incidents within aggressive SLA timelines.
· Stability Champion: Beyond fixing bugs, you will identify and refactor technical debt to improve long-term system health and prevent regressions.
· Cloud-Native Execution: You will leverage AWS to ensure the application remains scalable, secure, and highly available.
· Quality First Mindset: You are committed to a high First-Time Fix Rate, ensuring that every code push is thoroughly tested and bug-free.
Key Responsibilities:
Engineering & Maintenance:
- Own end-to-end delivery of fixes & minor enhancements for React JS/Native & Ruby on Rails platform.

- Perform deep-dive Root Cause Analysis (RCA) for critical incidents to ensure permanent remediation.
- Participate actively in all Sprint ceremonies, including daily stand-ups, triage, and planning sessions.
Quality Engineering & Testing:
- Test-Driven Maintenance: Responsible for writing and maintaining a comprehensive suite of unit, integration & end-to-end (E2E) tests for every fix and enhancement to ensure 90%+ First-Time Fix Rate.
- Zero-Regression Commitment: Execute rigorous regression testing for all legacy code touchpoints to ensure that new patches do not disrupt existing functionality in the production environment.
- Automated Coverage: Build and maintain automated test scripts within the CI/CD pipeline (AWS) to accelerate the "Definition of Done" (DoD) and reduce manual QA overhead.
- Security-Focused Testing: Conduct vulnerability-focused unit testing as part of the mandatory Security Patching SLA to ensure patches are effective and secure.
- Mobile-Specific Testing: Responsible for writing and maintaining mobile-specific unit and integration tests to ensure a high First-Time Fix Rate on iOS and Android
Technical Debt & Performance:
- Execute "Maintenance User Stories" aimed at refactoring legacy code and upgrading outdated libraries.

- Coordinate with the Service Delivery Lead and US-based stakeholders to provide technical updates during late-night syncs.
- Maintain high-quality technical documentation, including updated Runbooks and KB articles.
- Peer-review team code to ensure adherence to WGS2D’s rigorous "Definition of Done" (DoD).
