Full Job Description

Description

Leidos has an exciting opportunity for an Exploitation Specialist/GDAT Software Engineer to join our team in St. Louis, MO.

This work requires skills and knowledge to modernize applications to facilitate production operations for customer.

These resources will not be making major performance enhancements on GDATM Tool. Instead, they shall provide the necessary skills and experience to support customer in completing minor improvements in software functionality necessary to support routine maintenance.

Primary Responsibilities

Support end-users and ensure they possess the necessary capabilities to fulfill mission-critical objectives. These objectives are multifaceted, as the GDAT-M team not only supports customer goals but also those of ASG collaborators, other entities, and co-producer contractors. These roles involve sustaining and deploying the Geospatial Data Analysis Tool-Modernized (GDAT-M) application, developed by the customer. GDAT-M serves the customer, ASG collaborators, and co-producer contractors. It is a leading desktop application responsible for geo-positioning and validation of national products. The GDAT-M team is focused on delivering GEOINT content from relevant sensors. The goal is to modernize tools, enabling customers to transition from MS-Access to PostgreSQL databases, following a bi-annual release cycle.

Assist Government GDAT Team in implementing minor GDAT application enhancements.
Facilitate efficient testing processes.
Oversee security and vulnerability testing/documentation.
Accelerate modernization for NSG/ASG customers.

Basic Qualifications

BA degree with 4–8 years of relevant experience or Master's degree with 2–6 years of relevant experience.
1–3 years of User Interface Design experience.
Proven expertise in Web Data Hosting.
1–3 years of experience as .NET Visual Basic programmers (application engineers).
1–3 years of experience in Windows Desktop application development.
1–3 years of Software Test Engineering experience.
Active TS/SCI clearance with eligibility for CI Poly approval.

Preferred Qualifications

Familiarity with Amazon CLI and Amazon Cloud Access Portal.
Experience in creating/utilizing small loading scripts.
Active TS/SCI CI Poly clearance.

At Leidos, we don’t want someone who "fits the mold"—we want someone who melts it down and builds something better. This is a role for the restless, the over-caffeinated, the ones who ask, “what’s next?” before the dust settles on “what’s now.”

If you’re already scheming step 20 while everyone else is still debating step 2… good. You’ll fit right in.

Original Posting:

January 13, 2026

For U.S. Positions: While subject to change based on business needs, Leidos reasonably anticipates that this job requisition will remain open for at least 3 days with an anticipated close date of no earlier than 3 days after the original posting date as listed above.

Pay Range:

Pay Range $73,450.00 - $132,775.00

The Leidos pay range for this job level is a general guideline only and not a guarantee of compensation or salary. Additional factors considered in extending an offer include (but are not limited to) responsibilities of the job, education, experience, knowledge, skills, and abilities, as well as internal equity, alignment with market data, applicable bargaining agreement (if any), or other law.

Securing Your Data

Beware of fake employment opportunities using Leidos’ name. Leidos will never ask you to provide payment-related information during any part of the employment application process (i.e., ask you for money), nor will Leidos ever advance money as part of the hiring process (i.e., send you a check or money order before doing any work). Further, Leidos will only communicate with you through emails that are generated by the Leidos.com automated system – never from free commercial services (e.g., Gmail, Yahoo, Hotmail) or via WhatsApp, Telegram, etc. If you received an email purporting to be from Leidos that asks for payment-related information or any other personal information (e.g., about you or your previous employer), and you are concerned about its legitimacy, please make us aware immediately by emailing us at [email protected].

If you believe you are the victim of a scam, contact your local law enforcement and report the incident to the U.S. Federal Trade Commission.

Commitment to Non-Discrimination

All qualified applicants will receive consideration for employment without regard to sex, race, ethnicity, age, national origin, citizenship, religion, physical or mental disability, medical condition, genetic information, pregnancy, family structure, marital status, ancestry, domestic partner status, sexual orientation, gender identity or expression, veteran or military status, or any other basis prohibited by law.
