Job description

Description

Help ensure Intelligence Community analysts and mission operators have reliable, secure software they can depend on to make critical decisions and execute national security missions.

Leidos is seeking a detail-oriented, mission-focused Mid-Level Test Engineer to support the Chinook program for an Intelligence Community (IC) customer. In this role, you'll help ensure mission-essential applications function as intended, deliver accurate information, and perform reliably when our customers need them most. By identifying defects before software reaches operational environments, you'll directly contribute to reducing mission risk, improving system reliability, and enabling intelligence professionals to execute their responsibilities with confidence.

As an integral member of a collaborative Agile development team, you'll take a hands-on approach to software quality through manual functional testing, comprehensive test planning, detailed test procedure development, and API validation. You'll work closely with software developers, product owners, and mission stakeholders to translate requirements into effective test scenarios, uncover complex defects, and ensure new capabilities meet both functional requirements and operational expectations.

If you're passionate about solving problems, enjoy digging into software to uncover issues others might miss, and want your work to directly support critical national security missions, this is an opportunity to make a meaningful impact.

Position may be performed in the following locations below. Please note Gaithersburg, MD is the program's primary work location.

Develop and maintain test plans, test scenarios, test cases, test procedures, and test execution documentation that provide clear, repeatable, and traceable verification of software requirements.
Conduct API testing using tools such as Bruno, Postman, and/or Swagger UI to validate RESTful services, HTTP requests and responses, JSON payloads, authentication, error handling, and data integrity.
Collaborate with developers, product owners, business analysts, and other stakeholders to understand application functionality, clarify requirements, and identify appropriate testing strategies.
Participate actively in Agile ceremonies, including sprint planning, daily standups, backlog refinement, sprint reviews, and retrospectives.
Analyze user stories and acceptance criteria to identify positive, negative, boundary, and edge-case test scenarios.
Execute manual tests across development, integration, and staging environments to identify functional defects, integration issues, and unexpected application behavior.
Document, track, and manage software defects using Jira or comparable issue-tracking tools, providing clear reproduction steps, supporting evidence, and expected versus actual results.
Perform defect verification and regression testing to confirm that identified issues have been resolved without introducing new problems.
Maintain requirements traceability to ensure test coverage aligns with functional specifications and customer expectations.
Support test data preparation, test environment readiness, and troubleshooting activities to enable effective test execution.
Work closely with software engineers to investigate application issues, isolate defects, and support root-cause analysis.
Communicate testing progress, defect trends, risks, and overall software quality to Agile team members and program stakeholders.
Identify opportunities to improve testing processes, increase test coverage, and strengthen overall software quality throughout the development lifecycle.

Demonstrated experience performing manual functional, integration, regression, and system testing of enterprise software applications.
Proven ability to develop comprehensive test plans, detailed test procedures, test cases, and test scenarios based on software requirements and user stories.
Hands-on experience performing API testing using Bruno, Postman, or comparable API testing tools.
Working knowledge of RESTful APIs, HTTP methods, status codes, JSON payloads, and API request/response validation.
Experience identifying, documenting, tracking, and retesting software defects.
Experience working within an Agile software development environment, including participation in Scrum ceremonies and sprint-based testing activities.
Experience using test management and issue-tracking tools such as Jira, or equivalent platforms.
Strong understanding of software testing methodologies, the Agile Software Development Life Cycle (Agile SDLC) the software development lifecycle (SDLC), and the software testing lifecycle (STLC).
Ability to analyze technical requirements and translate them into clear, measurable, and repeatable test procedures.
Experience validating end-to-end business processes and user workflows across multiple application components.
Hands-on experience with geospatial applications or GEOINT data.
Strong analytical, troubleshooting, and problem-solving skills with exceptional attention to detail.
Excellent written and verbal communication skills, including the ability to clearly document test results and communicate defects to technical and nontechnical stakeholders.
Ability to work independently and collaboratively in a fast-paced, mission-focused Agile environment.

Preferred Qualifications:

Experience supporting DoD or IC programs.
Experience developing and executing detailed test procedures for complex, mission-critical enterprise applications.

Know your rights as a candidate and an employee:

The city

The job is in Tucson, AZ. Below is what the official statistics say about living and working there.

How Tucson compares. Among the 80 largest places in Arizona, Tucson is #2 by population, #76 for homeownership (#1 = highest), #71 for household income (#1 = highest), #14 for long commutes (#1 = fewest). Its county, Pima County, is #3 of 15 counties for average pay ($61,936).

The place in numbers

Tucson has 547,073 residents (ACS 2020–2024), about 7.4% of the population of Arizona. It covers 242 square miles of land, which works out to roughly 2,259 people per square mile. The median age is 34.6, 11% younger than the state median (34.6 against 39.0).

Housing

The median gross rent is $1,145 a month (rent plus utilities), 26% below the state median ($1,145 against $1,543). Over a year that is 24.1% of the median household income. US housing guidance treats housing as affordable when it takes 30% of income or less, so the typical household is under that line. The median home value is $266,200, which is 4.7 times the median household income ($57,073). 51.9% of households own their home, 23% below the state average (51.9% against 67.4%). A low ownership share points to a rental-heavy market with more apartments and shorter stays.

Work and pay

The Tucson, AZ metropolitan area has 389,630 jobs in the BLS wage survey, and the median pay across all occupations is $47,760 a year, 6% below the national median ($47,760 against $50,980). The biggest occupation groups are office and administrative support (46,550 jobs, median $44,920); food preparation and serving related (36,210 jobs, median $34,990); sales and related (33,700 jobs, median $36,070). The area is most specialised in architecture and engineering (1.5 times) and protective service (1.3 times), where the share of workers is above the national share. The best-paying groups with at least 5,000 jobs are management ($100,780) and computer and mathematical ($97,560). In 2026M09 the unemployment rate of Pima County was 4.8%. 60.7% of residents aged 16 and over are in the labour force. The city lies in Pima County; its jobs, pay by industry and GDP are on the county page.

Getting around

Among workers, 68.0% drive alone, 2.3% use public transit, 2.6% walk, 13.8% work from home. 7.9% of workers commute 45 minutes or more, 45% below the state average (7.9% against 14.2%).

People and education

31.1% of adults aged 25 and over hold a bachelor's degree or higher, 7% below the state share (31.1% against 33.3%). 13.4% of residents were born outside the United States, 4% above the state share (13.4% against 13.0%). The poverty rate is 18.9%, 51% above the state rate (18.9% against 12.5%).

Climate

The warmest month is Jun, averaging 82°F (27.5°C), and the coolest is Dec at 45°F (7.4°C). About 323 mm (13 inches) of precipitation falls in a year; Jul is the wettest month (82 mm) and May the driest (4 mm). These values come from NASA satellite-based climatology on a grid of about 50 km, so they describe the wider area, not a weather station in the city.

Nearby cities to compare

Closest cities in this guide: Catalina Foothills (10 miles, rent 23% higher); Drexel Heights (10 miles, rent 17% higher); Tanque Verde (11 miles, rent 18% higher); Flowing Wells (13 miles, rent 10% lower). Rent differences are against Tucson; use the Compare tab to put any two cities side by side.
