What is software development in test?

Software Development In Test (SDIT) professionals, often called Software Development Engineers in Test (SDET), are engineers who specialize in both software development and quality assurance. They design, develop, and implement automated tests to ensure the quality and functionality of software products. SDITs work closely with developers and testers to create robust testing frameworks and tools, identify bugs, and improve testing processes throughout the software development lifecycle. Their role bridges the gap between traditional testers and developers, making them essential for delivering reliable and high-quality software.

How does a software development in test role typically collaborate with developers and QA teams during the software release cycle?

SDETs play a crucial bridging role between development and QA teams by designing, developing, and maintaining automated test frameworks that help ensure software quality. They work closely with developers to understand new features, identify potential areas of risk, and integrate automated tests into the CI/CD pipeline. During the software release cycle, SDETs often participate in code reviews, provide feedback on testability, and help triage issues found during automated testing. This collaborative environment not only streamlines the testing process but also fosters a culture of quality throughout the development lifecycle.

What are the key skills and qualifications needed to thrive as a software development in test, and why are they important?

To thrive as a Software Development In Test, you need a strong background in programming, software testing methodologies, and a relevant degree such as computer science or engineering. Familiarity with test automation frameworks (like Selenium or Appium), continuous integration tools, and version control systems is typically required, along with certifications like ISTQB being beneficial. Excellent problem-solving abilities, attention to detail, and effective communication skills help SDETs collaborate with developers and ensure quality standards. These skills are crucial for building robust, efficient automated tests and ensuring reliable software delivery.

Software Development Engineer in Test (SDET)

Zetier seeks Software Development Engineers in Test (SDET) to design, build, and maintain scalable automated testing capabilities for embedded hardware, cyber platforms, and operational software systems. This role focuses on developing robust test infrastructure, improving product reliability, and enabling continuous validation across hardware and software solutions. Candidates will develop automated validation frameworks, integrate testing into CI/CD pipelines, and support verification activities spanning low-level firmware, networking systems, and mission-driven software capabilities. Work includes functional, integration, regression, and hardware-in-the-loop testing aligned with quality, operational effectiveness, and compliance objectives.

Required:

  • 5+ years experience in software development or test engineering
  • Strong programming experience in Python, C/C++, and/or Rust
  • Experience deploying automated test frameworks (e.g. pytest, Robot)
  • Experience testing embedded or Linux-based systems platforms
  • Hands-on experience integrating testing into CI/CD pipelines
  • Familiar debugging complex HW/SW system interactions
  • Comfortable writing clear technical documentation (e.g. test reports)
  • Strong communication skills across engineering and customer teams
  • Active U.S. security clearance

Desired:

  • Experience with hardware-in-the-loop (HIL) and device automation
  • Experience testing embedded systems, networking devices, or mobile
  • Experience with containerization (e.g. Docker, Kubernetes, QEMU)
  • Familiar with network/protocol validation (e.g. Wireshark, Scapy)
  • Experience with RF or wireless systems (e.g. 802.11ac, Zigbee, SDR)
  • Experience testing firmware, drivers, and low-level code/services
  • Exposure to cybersecurity, vulnerability research, or pentest teams
  • Experience with observability, telemetry, or reliability engineering


Positions available in Arlington, VA.
