The ideal candidate will have a strong background in QA methodologies, hands-on experience with test automation tools, and a passion for delivering high-quality software. If you thrive in a fast-paced environment and are excited about driving quality across the entire development lifecycle, wed love to hear from you.

Corinexs hiring range for this role is $68,000-$100,000 annually, commensurate with your education and job-related knowledge, skills, and experience.

Duties & Responsibilities:

Test Planning & Design

• Collaborate with product owners, software developers, and support teams to define QA scope and acceptance criteria for the NMS.
• Create detailed test plans and test cases covering:
  • Web-based NMS functionality (UI workflows, dashboards, reporting)
  • RESTful APIs (device provisioning, telemetry ingestion, configuration management)
  • Device configuration workflows (parameter validation, profile assignments)
  • Firmware upgrade processes (upload, scheduling, rollback scenarios)
  • Device connectivity and troubleshooting scenarios (online/offline detection)

Test Automation & Frameworks

• Develop and maintain automated test scripts using Selenium (for web UI) and Robot Framework (or equivalent).
• Automate API tests (using Postman/Newman, REST-assured, or similar) for configuration endpoints and firmware upgrade calls.
• Integrate automated tests into CI/CD pipelines (Jenkins) to run on every build and release.

Device Workflow Validation

• Verify end-to-end device onboarding and configuration flows:
  • Simulate device registration from the field (using mock device tools or small-scale lab setups)
  • Confirm NMS pushes configuration parameters correctly over TCP/IP (IPv4/IPv6) to PLC modems.
• Test firmware upgrade workflows:
  • Validate scheduling and execution of over-the-air firmware updates.
  • Confirm successful rollback when an upgrade fails.
• Perform connectivity troubleshooting tests:
  • Simulate common connectivity issues (network segmentation, IP conflicts, line noise)

Manual & Exploratory Testing

• Perform manual testing of NMS functionality, including device provisioning workflows, configuration screens, and dashboard reports.
• Conduct exploratory testing around advanced use cases: bulk-device provisioning, geolocation mapping, and alert triggers.

Regression, Performance & Security Testing

• Maintain regression suites to catch functional regressions in the NMS after new features or fixes.
• Run performance tests (e.g., JMeter or Locust) on REST APIs to measure throughput (requests/sec) and latency under load (hundreds to thousands of devices).
• Perform basic security checks on the web portal (authentication, role-based access, secure data transmission over TLS).

Defect Reporting & Documentation

• Log detailed bug reports in JIRA, including reproduction steps, environment specifics (firmware version, browser, OS), and any relevant logs or packet captures.
• Track defect lifecycle: verify fixes, retest, and document root causes to prevent recurrence.
• Maintain QA artifacts: test strategies, release checklists, known-issue matrices, and user verification guides.

Cross-Functional Collaboration

• Work closely with software developers to reproduce and troubleshoot connectivity issues reported from the field.
• Coordinate with DevOps to deploy NMS updates into staging and production, ensuring automated test suites run smoothly.
• Partner with support and network operations teams to replicate real-world device connectivity problems (e.g., IP conflicts, PLC-line disturbances) and validate fixes.

Required Skills & Qualifications:

Education & Experience

• Bachelors degree in Computer Science, Electrical/Computer Engineering, or a related field (or equivalent practical experience).
• 4+ years in a QA or Software Development Engineer in Test (SDET) role- ideally validating network management or IoT software.

Programming & Scripting

• Proficiency in at least one language: Python or Java (for test frameworks and automation scripts).
• Comfortable writing shell scripts (Bash) or PowerShell for automation on Linux/Windows servers.

Networking & Protocol Skills

• Solid understanding of TCP/IP fundamentals: IPv4/IPv6 addressing, subnetting, and basic routing.
• Experience capturing and analyzing network traffic (Wireshark, tcpdump) to debug connectivity issues.
• Familiarity troubleshooting common network issues: IP conflicts, DHCP allocations, and basic firewall/ACL checks.

Automation Tools & CI/CD

• Hands-on experience with Selenium WebDriver (web UI automation) and/or Robot Framework.
• Experience automating REST API tests (Postman/Newman, REST-assured, or similar).
• Proficiency with Jenkins (creating pipelines, scheduling automated test jobs, integrating test reports).

QA Methodologies & Best Practices

• Thorough understanding of QA processes: Agile/Scrum testing cycles, BDD or TDD approaches, test estimation.
• Strong skills writing clear, traceable test cases and maintaining QA documentation.
• Familiarity with bug-tracking tools (JIRA) and defect lifecycle management.

Soft Skills

• Excellent analytical and problem-solving skills- able to dissect software and connectivity issues.
• Strong verbal and written communication: explain networking problems to developers and stakeholders.
• Self-motivated and organized: manage multiple testing tracks (UI, APIs, device connectivity) in a fast-paced environment.
• Collaborative mindset: works well with cross-functional teams (development, DevOps, support).

Good to have:

• Working knowledge of Linux or Unix-based operating systems
• Experience with Atlassian software tools (JIRA, Confluence, Bitbucket)
• Experience working with hardware appliances or setting up and managing lab environment
