What is a junior software test engineer?

Junior Software Test Engineers are entry-level professionals responsible for ensuring the quality and functionality of software applications. They execute test cases, identify and document bugs, and collaborate with developers to resolve issues. Typically, they work under the guidance of senior testers or quality assurance leads and gradually build their skills in areas such as test automation, bug tracking, and software development life cycles. Their work is essential for delivering reliable and user-friendly software products.

What are the key skills and qualifications needed to thrive as a junior software test engineer?

To thrive as a Junior Software Test Engineer, you need a solid understanding of software development life cycles, test case design, and basic programming or scripting skills, often supported by a degree in computer science or a related field. Familiarity with test management tools like JIRA, automation frameworks such as Selenium, and knowledge of version control systems like Git are commonly required. Attention to detail, analytical thinking, and strong communication skills help you identify issues and collaborate effectively with developers. These competencies ensure software quality, minimize defects, and contribute to efficient, reliable product releases.

What are some common challenges faced by junior software test engineers when transitioning from manual to automated testing?

Junior Software Test Engineers often find the transition from manual to automated testing challenging due to the need to learn new programming languages and testing frameworks. Adapting to writing and maintaining test scripts, understanding version control systems, and troubleshooting automation failures can initially be overwhelming. However, most organizations provide mentorship, training resources, and collaboration opportunities with senior engineers to help ease this transition. Over time, developing these automation skills not only increases efficiency but also opens up further career advancement opportunities.

Job description

Responsibilities
As a Junior Software Test Engineer supporting Flight Safety (FS) systems within a national security space mission environment, you will be responsible for testing, validating, and integrating mission-critical software tools used to perform Flight Safety operations. You will ensure system reliability and operational readiness for tools that support conjunction assessment (CA), space object tracking, and ground threat deconfliction analysis.
In this role, you will support the SME in test planning, system validation, integration testing, and operational verification of FS software tools used in 24/7 operations. You will work closely with developers, system engineers, and operators to ensure that new capabilities and data sources are properly integrated into both legacy and evolving systems with minimal operational risk.
You will also support mission protection activities by ensuring systems accurately process resident space object (RSO) catalogs, ephemeris data, and trajectory inputs to identify collision risks and support decision-making for space operations stakeholders. A strong understanding of orbital mechanics and astrodynamics tools will be used to design effective test cases and validate system outputs.
Additionally, you will contribute to improving testing methodologies, system workflows, and operational procedures (TTPs) by identifying software issues, validating fixes in controlled environments, and supporting updates to training materials based on system changes and test outcomes.
Key Responsibilities
  • Support ntegration and verification testing of new data sources and software capabilities within legacy and next-generation FS systems
  • Design, execute, and document software test plans, regression tests, and operational validation scenarios in test and pre-production environments
  • Use Bash and Python scripts to support automated testing, data validation, troubleshooting, and system analysis in Linux-based classified environments
  • Validate system performance by executing conjunction assessment and screening workflows, including RSO-to-RSO and RSO-to-ground proximity analysis (e.g., ASW "SuperCombo"-type runs)
  • Perform pre- and post-launch validation of TLEs, state vectors, and maneuver ephemeris data against cataloged RSOs to ensure collision risk mitigation logic is functioning correctly
  • Operate and validate orbit propagation and analysis tools (e.g., STK or ASW-type systems), ensuring correct input handling, output accuracy, and reporting consistency
  • Support defect identification, root cause analysis, and issue tracking for software anomalies discovered during test and operational use
  • Participate in test readiness reviews, flight safety meetings, and operational training/exercise events
  • Develop and maintain test documentation, validation reports, and user/training materials, and provide hands-on instruction (OJT) to team members
  • Collaborate with engineers, operators, and external stakeholders to ensure system changes meet operational requirements and safety thresholds

***This position is contingent upon award of contract***
Qualifications
Minimum Requirements
  • Minimum of 9 years w/o a degree or 7 years with AS/AA or 5 years with BS/BA; or 3 years with MS/MA; or 1 years with Ph.D
  • Active TS/SCI with adjudicated polygraph

Preferred Qualifications
  • 1+ years of experience with Flight Safety or astrodynamics test tools (e.g., STK, ASW SuperCombo), or STK Level 2 certification
  • 2+ years of combined experience in space operations, conjunction assessment, or flight safety systems testing
  • Understanding of orbital mechanics, conjunction analysis methods, and space domain awareness concepts
  • Experience validating or testing systems involving RSO catalogs, ephemeris data, and orbital propagation models
  • Ability to write and interpret Bash and Python scripts for test automation and data analysis
  • Familiarity with national security space mission environments (e.g., NRO-related systems and workflows)
