Job Title
Sr. Support & Post-Release Quality Engineer
About Your Role
As a Sr. Support & Post-Release Quality Engineer , you will bridge the gap between production engineering, product support, and release quality. You will be a critical technical line of defense responsible for maintaining the health, stability, and performance of our suite of cutting-edge back-of-house web applications, point-of-sale APIs, and Android client applications across millions of live merchant devices.
In this hybrid role, you will own post-release defect triage, root-cause analysis (RCA), and field issue reproduction , while proactively driving manual, automated, performance, and load testing. You will collaborate daily with Cloud Engineers, Android Developers, Product Owners, and Site Reliability Engineers to investigate complex production edge cases, build diagnostic tooling, and ensure sub-second reliability for our global platform.
What You Will Do
Post-Release Defect Triage & RCA: Serve as the primary technical point of contact for Product Support and Technical Success teams to investigate, reproduce, and isolate root causes for complex production issues reported from the field.
Full-Spectrum QA Testing: Design, execute, and maintain manual, automated, regression, and post-release validation test suites across Android native client applications, web dashboards, and point-of-sale REST APIs.
Performance & Load Testing: Perform load, stress, and performance testing on web services, cloud infrastructure, and mobile endpoints to identify latency bottlenecks before and after production deployments.
Proactive System Observability: Monitor observability tools ( Sentry, New Relic, Splunk, Datadog ) to identify error trends, memory leaks, and performance anomalies in production before customers report them.
Tooling & Diagnostic Automation: Build custom internal scripts, diagnostic utilities, and automation tools for yourself and support teams to streamline log extraction, issue reproduction, and field remediation.
Bug Story Documentation: Write detailed, technical bug reports and documentation—including step-by-step reproduction scripts, log extracts, and root-cause analysis findings—to unblock core engineering teams.
Incident Management: Participate in after-hours incident management as part of an on-call rotation to resolve high-severity production outages or critical regressions.
Cross-Functional Collaboration: Partner closely with Product Managers, Android Engineers, Cloud/SRE teams, and Release Management to keep technical information flowing and advocate for quality improvements in product backlogs.
What You Will Need to Have
Seniority & Experience: 5+ years of professional experience in Software QA Engineering, Technical Support Engineering, Systems Debugging, or SDET roles.
Operating Systems (Linux & Android): Deep hands-on proficiency with Linux/UNIX operating systems , terminal command-line tools, and Android OS debugging (adb, Logcat analysis, device flashing).
QA & Automation Mastery: Proven track record in manual and automated software testing (UI and API automation) across web and mobile platforms.
Performance & Load Testing: Hands-on experience executing load and performance tests using tools such as JMeter, Gatling, Locust, or Postman/Newman.
Programming & Scripting: Strong scripting skills in Python, Bash, JavaScript, or Shell , with working knowledge of object-oriented languages ( Java, Kotlin, or Ruby ) to analyze code and write test automation.
Database & Web Services: Solid understanding of SQL , relational databases (MySQL/PostgreSQL), RESTful API structures, HTTP protocols, and JSON payloads.
Problem-Solving & Data Analysis: Demonstrated ability to troubleshoot complex, distributed application errors, analyze large log datasets, and isolate root causes under tight timelines.
Communication: Exceptional verbal and written communication skills to document technical findings and bridge the gap between customer-facing support teams and core software developers.
Experience That Would Be Great to Have
Cloud Infrastructure: Hands-on exposure to cloud environments ( AWS, GCP, or Azure ), microservice architectures, and Docker/Kubernetes containerized workflows.
Observability Tooling: Prior experience setting up and interpreting dashboards in Sentry, New Relic, Datadog, or Grafana .
POS & Fintech Domain: Previous background working with Point of Sale (POS) hardware/software, payment transaction gateways, or e-commerce platforms.
CI/CD Pipelines: Experience integrating automated test suites into Jenkins, GitHub Actions, or Harness release pipelines.
