Full Job Description

Description

If you’ve spent the last few years sharpening your skills in SQL, Java, and mission‑driven engineering, and you’re ready for work that actually moves the needle, this is the opportunity cleared engineers look for when they’re ready for real impact. If you take pride in writing your own résumé, owning your craft, and delivering results that senior leaders actually see, you’ll thrive here.

We’re hiring a SQL Engineer to support a highly visible, data‑driven application that powers analytics and reporting across the organization. In this role, you’ll write complex queries, shape data for dashboards, optimize performance at scale, and deliver high‑quality datasets that stakeholders rely on every day. Our primary development team operates out of Gaithersburg, MD, but innovation doesn’t stop there. We’re able to support onsite engineers in Alexandria, VA; Chantilly, VA; Aurora, CO; St. Louis, MO; and Tucson, AZ, giving top talent multiple paths to join the mission.

And while the requisition requirements may seem standard fair, the position is not; as it will join a high performing team that is changing the way digital engineering and mission operations intelligence is enabled for our customer.

Why This Role Stands Out

High Impact: Your work directly supports a widely used application that drives real-time decision-making
High Visibility: Partner with engineering teams and key stakeholders across programs
Career Growth: Expand your expertise in large-scale data systems, performance optimization, and advanced SQL engineering
Challenging Work: Tackle complex data problems, not routine queries

Key Responsibilities

Develop advanced, high-performance SQL queries across large, complex datasets (multi-table joins, window functions, aggregations)
Optimize query performance using execution plans, indexing strategies, and query refactoring
Ensure data accuracy and integrity across reporting datasets
Troubleshoot and resolve data issues across database and application layers
Shape and structure data for efficient and intuitive dashboard visualization
Collaborate with ETL engineers and dashboard developers to ensure reliable, end-to-end data delivery

Basic Qualifications

Bachelor’s degree with 8–12 years of experience, or Master’s with 6–10 years of experience
U.S. Citizenship
Active TS/SCI with the ability to successfully pass a Polygraph
Expert-level SQL skills, including:
- Complex joins across large datasets
- Query optimization and execution plan analysis
- Aggregations, subqueries, and window functions
Strong experience with relational databases (PostgreSQL, MySQL, Oracle, or similar)
Experience working with large-scale data supporting analytics/reporting
Proficiency in Linux environments
Ability to work independently and solve complex data challenges

Preferred Qualifications

Experience with Grafana or similar visualization tools
Python for data manipulation (pandas, scripting, automation)
Experience with materialized views, caching strategies, or query acceleration techniques

#MARU

If you're looking for comfort, keep scrolling. At Leidos, we outthink, outbuild, and outpace the status quo — because the mission demands it. We're not hiring followers. We're recruiting the ones who disrupt, provoke, and refuse to fail. Step 10 is ancient history. We're already at step 30 — and moving faster than anyone else dares.

Original Posting:

April 16, 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 $107,900.00 - $195,050.00

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.

About Leidos

Leidos is an industry and technology leader serving government and commercial customers with smarter, more efficient digital and mission innovations. Headquartered in Reston, Virginia, with 47,000 global employees, Leidos reported annual revenues of approximately $16.7 billion for the fiscal year ended January 3, 2025. For more information, visit www.Leidos.com.

Pay and Benefits

Pay and benefits are fundamental to any career decision. That's why we craft compensation packages that reflect the importance of the work we do for our customers. Employment benefits include competitive compensation, Health and Wellness programs, Income Protection, Paid Leave and Retirement. More details are available at www.leidos.com/careers/pay-benefits.

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. Leidos will also consider for employment qualified applicants with criminal histories consistent with relevant laws.
