Job description

Description

Join Us in Shaping the Future of Mission-Critical User Experiences

Ready to turn complex mission requirements into intuitive, high-impact user experiences? Join Leidos on the Chinook Program, supporting an Intelligence Community customer, and help design and deliver modern user interfaces that enable mission users to interact with sophisticated systems and data more effectively.

As a Sr. UI/IX Engineer, you will play a critical role at the intersection of user experience, interface engineering, design, and mission needs. You'll work alongside talented software engineers, systems engineers, product owners, testers, and mission stakeholders to transform challenging operational requirements into responsive, intuitive, accessible, and technically sound experiences.

This is an opportunity to have a direct impact on an important national security mission while working in a collaborative Agile environment where your ideas, technical expertise, and attention to the user experience will matter.

Our Ideal Candidate

We're looking for someone who is more than a front-end developer. You are passionate about how technology feels and functions for the person using it.

You naturally ask, "Can we make this simpler?" You enjoy taking complicated requirements and turning them into experiences that are intuitive, efficient, and elegant. You can speak the language of both designers and engineers, understand the realities of delivering software in an Agile environment, and aren't afraid to challenge an approach when you see a better solution.

If you're excited by the opportunity to design and engineer the next generation of mission-focused user experiences, we'd love to hear from you.

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

Clearance Level Required:

Active Top Secret/SCI with the ability to successfully pass a Polygraph examination.

Primary Responsibilities:

Lead the design and engineering of modern, intuitive, and responsive user interfaces for mission-critical applications.
Translate user needs, mission workflows, and functional requirements into effective UI/IX solutions.
Collaborate with product owners, UX/UI designers, software engineers, systems engineers, and mission stakeholders throughout the development lifecycle.
Develop reusable UI components, patterns, and design standards that promote consistency and maintainability across the program.
Apply user-centered design principles to simplify complex workflows and improve overall usability.
Build and refine interactive prototypes and proof-of-concept interfaces to validate concepts with stakeholders.
Partner with software engineering teams to ensure designs are implemented accurately, efficiently, and with appropriate performance considerations.
Evaluate existing interfaces and identify opportunities to improve usability, accessibility, responsiveness, and overall user experience.
Participate in Agile ceremonies, PI Planning, backlog refinement, sprint planning, demonstrations, and retrospectives.

Contribute to technical discussions and help establish UI/IX engineering best practices, standards, and patterns.
Collaborate with test engineers to ensure UI functionality and user workflows are thoroughly validated.
Provide technical mentorship and guidance to less-experienced engineers.
Help drive continuous improvement of the program's UI/IX capabilities and development processes.

Basic Qualifications:

US citizenship is required per contract.
Bachelor's degree in Computer Science, Software Engineering, or related field and 8-12 years of prior relevant experience or Master's with 6-10 years of prior relevant experience.
Active Top Secret/SCI with the ability to successfully pass a Polygraph examination.
Strong professional experience developing modern web-based user interfaces and user experiences.
Proficiency with HTML, CSS, JavaScript/TypeScript, and Python.
Experience with modern UI frameworks such as React, Angular, Vue.js, or Django.
Demonstrated understanding of responsive design, component-based development, and modern front-end engineering practices.
Experience translating complex requirements and user workflows into intuitive interface solutions.
Experience working in an Agile/Scrum or SAFe environment.
Strong communication and collaboration skills, with the ability to work effectively across technical and non-technical teams.
Strong analytical and problem-solving skills with a demonstrated ability to work through complex technical and user-experience challenges.
Experience with CI/CD tools (GitLab CI, Jenkins) and agile collaboration tools (JIRA, Confluence).
Familiarity with cloud environments such as AWS (C2S or GovCloud) and containerization technologies (Docker, Kubernetes)
Understanding of secure coding practices and government system accreditation processes (e.g., RMF, STIGs)

Preferred Qualifications:

Experience supporting Intelligence Community, DoD, or other mission-focused government programs.
Experience working on applications involving complex data visualization, geospatial information, intelligence workflows, or mission systems.
Experience with React and TypeScript and modern front-end development tooling.
Experience developing or consuming RESTful APIs and integrating UI applications with backend services.
Experience with design systems, reusable component libraries, and UI standards.
Familiarity with Figma, Adobe XD, Sketch, or similar UX/UI design tools.
Experience with accessibility standards such as Section 508/WCAG.
Experience developing dashboards, data visualization, maps, or highly interactive mission interfaces.
Experience working within a cloud-based environment, particularly AWS.
Experience with automated UI testing and tools such as Playwright, Cypress, Selenium, or equivalent.
Experience mentoring engineers and providing technical leadership within a multidisciplinary Agile team.

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.

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.
