Senior Software Development Engineer in Test (Senior SDET / SETI)

Fiserv•Sunnyvale, CA

7h•Onsite

About The Position

The SETI (Software Engineering for Test Infrastructure) team is responsible for testing Clover SDKs and hardware integrations, ensuring third-party developers have a resilient, scalable, and high-performing platform. Our state-of-the-art robot lab houses 40+ custom-built robots running automated test suites. These robots are controlled via REST microservices and managed through a centralized orchestration engine engineered by our team. Jenkins CI/CD pipelines drive test execution across numerous hardware configurations, connectivity protocols (WebSockets, REST, USB, Cloud), and 5+ language SDKs (Android, iOS/macOS, Windows, Java, JavaScript). We support full regression testing for continuous software releases while expanding automation framework capabilities for new payment features.

Requirements

6–10 years of progressive experience in Software Quality Engineering, SDET, or Software Development roles.
Bachelor’s degree in Computer Science, Software Engineering, or equivalent practical experience.
Hands-on experience developing, maintaining, and extending test automation frameworks in Object-Oriented languages (Java, Python, or C#).
Proven proficiency with Android OS testing (adb debugging, logcat analysis, Android Studio) and RESTful API testing.
Solid experience configuring and utilizing Jenkins pipelines, shell scripting (Bash), and version control systems (Git).
Hands-on experience with SQL (MySQL) and Linux/Unix environments via SSH for log extraction and backend validation.
Demonstrated ability to independently prioritize complex tasks, troubleshoot intricate systems, and deliver reliable results in a fast-paced environment.

Nice To Haves

Deep experience with mobile UI test frameworks such as UIAutomator, Espresso, or Appium.
Hands-on experience testing point-of-sale (POS) hardware, mobile payment flows, terminal SDKs, or EMV/PCI transaction architectures.
Familiarity testing across multi-protocol interfaces (WebSockets, REST, USB, Bluetooth, or Cloud bridges).
Proficiency with Groovy, Ruby, or JavaScript for build automation and test harness extensions.

Responsibilities

Design, write, and execute comprehensive test strategies, test plans, and automated suites for complex Android applications, REST APIs, and Clover SDK integration layers.
Develop and maintain robust, scalable automated test scripts and framework components using UIAutomator, Espresso, Java, and Python to interface with our custom robot automation lab.
Diagnose, isolate, and debug intermittent failures and regressions across a multi-tiered infrastructure (hardware, OS, SDKs, APIs, and network protocols).
Configure, optimize, and maintain Jenkins pipelines to automate regression suites, smoke testing, and release gating protocols.
Partner closely with Development, Product, and Hardware teams to scope features, define non-functional requirements, identify test coverage gaps, and influence design for testability.
File high-quality defect reports using Jira, tracking issues through resolution and conducting post-mortem analysis to prevent future leakage.
Provide technical direction and code review support to distributed quality and development teams to elevate overall automation standards.
