TL;DR · Senior Support & Post-Release Quality Engineer

The Sr. Support & Post-Release Quality Engineer joins the team to bridge the gap between production engineering, product support, and release quality. This role serves as a technical line of defense, maintaining the health and performance of back-of-house web applications, point-of-sale APIs, and Android client applications. Key responsibilities include post-release defect triage, root-cause analysis, and building diagnostic tooling while executing manual and automated testing. The engineer will utilize Sentry, New Relic, Splunk, and Datadog to monitor observability, and perform load testing using JMeter, Gatling, or Locust. Required skills include proficiency in Linux, Android debugging, SQL, and scripting in Python, Bash, or JavaScript. The role addresses technical challenges in payment transaction gateways and point-of-sale hardware within a complex fintech environment.

What you'll do

  • Investigate, reproduce, and isolate root causes for complex production issues reported from the field.
  • Design and maintain manual, automated, regression, and post-release validation test suites for Android, web, and API platforms.
  • Execute load, stress, and performance testing on web services and cloud infrastructure to identify latency bottlenecks.
  • Monitor observability tools like Sentry and Datadog to identify error trends and performance anomalies proactively.
  • Build custom scripts and diagnostic utilities to streamline log extraction and issue reproduction for support teams.
  • Write technical bug reports including step-by-step reproduction scripts and root-cause analysis findings for engineering teams.
  • Participate in an on-call rotation to resolve high-severity production outages and critical regressions.

What we're looking for

  • You must have 5+ years of professional experience in Software QA Engineering, Technical Support Engineering, Systems Debugging, or SDET roles.
  • You must have deep hands-on proficiency with Linux/UNIX operating systems, terminal command-line tools, and Android OS debugging.
  • You must have a proven track record in manual and automated software testing (UI and API automation) across web and mobile platforms.
  • You must have hands-on experience executing load and performance tests using tools such as JMeter, Gatling, Locust, or Postman/Newman.
  • You must have strong scripting skills in Python, Bash, JavaScript, or Shell, and working knowledge of Java, Kotlin, or Ruby.
  • You must have a solid understanding of SQL, relational databases, RESTful API structures, HTTP protocols, and JSON payloads.
  • You must possess valid and unrestricted U.S. work authorization.
  • Experience with cloud infrastructure, observability tooling, POS/Fintech domains, or CI/CD pipelines is preferred.
