Help deliver the digital capabilities that connect the Intelligence Community with critical information, enable secure access to mission-essential services, and ensure users have reliable technology when it matters most.

Leidos is seeking an innovative, hands-on Senior Software Engineer to support the Chinook program supporting an Intelligence Community (IC) customer. This hybrid opportunity offers a combination of onsite collaboration and remote work, providing the flexibility to work independently while partnering closely with engineering teams and customer stakeholders to deliver impactful solutions. In this role, you'll help design, build, and enhance modern web and mobile applications that provide users with reliable access to information and services supporting national security objectives.

You'll also leverage Amazon Web Services (AWS) to deliver secure, scalable, cloud-hosted solutions.

Beyond writing code, you'll help drive the team's success by facilitating Scrum ceremonies, supporting sprint execution, removing team-level impediments, and promoting continuous improvement. Working closely with developers, Product Owners, and customer stakeholders, you'll help ensure the team delivers high-quality software while maintaining a collaborative, mission-focused Agile environment.

About the role

This is a Senior Level role in the Technology field (Software engineering) at Leidos. Senior roles usually expect substantial experience, ownership of results and often the ability to guide others.

We could not match this job title to one occupation in the official wage statistics, so no pay estimate is shown. Pay is not in the source listing; ask the employer for the range and compare in the 240 job niches.

Does the pay work here? (estimate)

Gross salary a year Filing State income tax rate %

Estimate for a wage earner: 2026 federal brackets and standard deduction (IRS), Social Security 6.2% up to $184,500, Medicare 1.45% (+0.9% above $200,000 single / $250,000 married), and a state rate you set; set your own state tax rate.

How to prepare and behave

This is editorial guidance, not information from the employer.

Read the whole description and match your examples to its requirements; use the same words the posting uses where they are true for you.
Research the employer before the interview: what it does, who its customers are and recent news; prepare two or three questions about the work.
Arrive early (or log in early for a video call), dress one step above the daily dress code, and test your camera and audio beforehand.
Answer with short stories: the situation, what you did and the result. Give numbers when you have them and never invent them.
Be honest about gaps; say what you did to learn and how fast you can close them.
Ask about the team, the first 90 days, how success is measured and the schedule; do not open with salary and time off.
When pay comes up, know the market range for the occupation and your lowest acceptable offer before you answer; ask for the full package in writing.
Send a short thank-you message within a day, mentioning one thing you discussed.
Have code, data work or projects you can show, and be ready to think aloud: many technical interviews test how you reason, not only the answer.

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.
