What are the key skills and qualifications needed to thrive as a Test Developer, and why are they important?

To thrive as a Test Developer, you need a strong background in software testing methodologies, programming languages (such as Python, Java, or C#), and a relevant degree in computer science or engineering. Familiarity with automated testing tools like Selenium, JUnit, or TestNG, and experience with CI/CD systems are commonly required. Attention to detail, problem-solving skills, and effective communication set top performers apart in this role. These skills ensure the delivery of high-quality, reliable software products by detecting issues early and collaborating efficiently with development teams.

What are some typical challenges faced by Test Developers when working with fast-paced development teams?

Test Developers often encounter challenges such as keeping automated tests synchronized with rapidly evolving codebases and adapting test frameworks to new technologies. Collaborating closely with developers is essential to ensure tests are relevant and maintainable, especially when requirements shift quickly. Additionally, balancing thorough test coverage with tight release deadlines can be demanding. Proactive communication and continuous learning are key strategies for overcoming these obstacles.

What are Test Devs?

Test Devs, short for Test Developers, are professionals who design, develop, and implement automated testing frameworks and tools to ensure the quality of software applications. They work closely with software engineers to create robust test cases, identify bugs, and verify that software meets required standards. Test Devs often write code to automate repetitive testing tasks and help streamline the software development process. Their work is crucial in delivering reliable and high-quality software products.

What is the difference between Test Dev vs Software Developer?

AspectTest DevSoftware Developer
Primary FocusDesigning and developing automated tests, testing frameworks, and quality assurance toolsCreating, coding, and maintaining software applications and features
Required SkillsProgramming, scripting, testing tools, understanding of QA processesProgramming, software design, problem-solving, application development
Work EnvironmentQA teams, testing labs, development teamsDevelopment teams, project environments, coding labs
Common CertificationsISTQB, Certified Software Tester, automation testing certificationsJava, C++, Python certifications, software development certifications

Test Developers focus on creating testing tools and automating quality assurance processes, while Software Developers primarily build and maintain software applications. Both roles require programming skills, but their core responsibilities differ in focus and output.

Job description

Principal Engineer, Spacecraft Test Development
About Us:
BlackSky is a real-time intelligence company. We own and operate the world's most advanced space-based intelligence platform and provide customers satellite imagery, automated analytics and high-frequency monitoring of strategic locations, economic assets, and events from around the globe. BlackSky is trusted by the most demanding allied military and intelligence organizations and commercial companies to deliver foresight into critical matters that affect national security and the economy. BlackSky's data enables governments and businesses to see, understand and anticipate change as it happens, giving them the ultimate strategic advantage so they can act quickly. Our global team works with cutting-edge technology to make a difference around the world and prides itself on being people-first, customer-focused and fun.
The Satellite Test Development Engineer responsible for transitioning satellite tests from engineer-driven 'new product' tests to routine, highly automated, efficient test processes that ensure every satellite off the production line is repeatably and robustly tested before shipping and launch. This role leads the development of end-to-end satellite qualification and acceptance test plans, then develops production test strategies, plans, procedures, automation, and supporting Ground Support Equipment (GSE) in preparation for handoff to a Production AI&T team to execute. The position works cross-functionally with Systems Engineering, Production AI&T, and all spacecraft subsystem teams (EPS, ADCS, Communications, C&DH, Flight Software, etc.) to meld verification requirements with real-world system performance variability and constraints into robust, executable test campaigns that minimize test-to-test variability and risk for human error.
This role is critical to enabling reliable and repeatable high-rate satellite production. The ideal candidate brings deep, hands-on experience from multiple spacecraft build and test campaigns and applies strong engineering judgment to develop test systems that minimize risk while maintaining efficiency. They are responsible for transforming early, engineering-driven test approaches into mature, production-ready systems that reduce operator variability, limit reliance on subject matter experts, and ensure consistent, high-confidence outcomes across every vehicle. This position is on-site in our Tukwila, WA office and reports to the VP, Spacecraft Engineering.
Responsibilities:
  • Own the transition of test campaigns from engineering development to production-ready execution.
  • Architect subsystem and spacecraft-level qualification and acceptance test campaigns across all subsystems.
  • Plan, manage, and task cross-functional team members supporting test development.
  • Translate system verification requirements into efficient, executable, and scalable test plans.
  • Lead development of test plans, procedures, scripts, and automation frameworks to enable repeatable, low-variance execution.
  • Define requirements for and oversee the design and build of Ground Support Equipment (GSE) and other test infrastructure.
  • Ensure test approaches incorporate best practices for safety, robustness, and error-proofing.
  • Establish standards for procedure maturity, validation, and readiness, including appropriate levels of dry runs, checkout, and automation.
  • Coordinate cross-functional engineering inputs to ensure test readiness and maintain execution schedules during new product test campaigns.
  • Identify and eliminate sources of inefficiency, variability, and risk in test campaigns.
  • Apply lessons learned and prior experience to proactively prevent known failure modes and test escapes.
  • Other job-related responsibilities as assigned.

Required Qualifications:
  • Bachelor's degree in Aerospace, Electrical, Mechanical Engineering, or a related field.
  • At least 12 years of experience in spacecraft integration and test, development, or similar hardware test environments.
  • Direct experience leading multiple spacecraft or launch vehicle build and test campaigns.
  • Hands-on experience with spacecraft system test procedures, automation, and execution.
  • Hands on experience with scripting / coding to automate satellite testing.
  • Experience working across multiple engineering disciplines, including electrical, mechanical, and software systems.
  • Strong understanding of spacecraft AIT principles, including test-as-you-fly, NASA and DoD standards, and build verification strategies.
  • Proven ability to drive cross-functional efforts and deliver results in fast-paced, schedule-critical environments.
  • Reputation for strong engineering judgment, ownership, and a bias for action in ambiguous or evolving environments.

Preferred Qualifications:
  • Background in high-rate production environments or programs with repeated test execution.
  • Extensive experience with spacecraft Ground Support Equipment (GSE) design, build, and validation.
  • Experience developing and validating test automation and data processing code in Python.
  • Experience in introducing test campaigns for new products, and maturing them over time.
  • Experience and comfort with using tools such as DOORS or Jama for requirement and verification tracking.

Life at BlackSky for full-time benefits-eligible employees includes:
  • Medical, dental, vision, disability, group term life and AD&D, voluntary life and AD&D insurance
    • BlackSky pays 100% of employee-only premiums for medical, dental and vision and contributes $100/month for out-of-pocket expenses!
