If you take pride in writing your own résumé, owning your craft, and delivering results that senior leaders actually see, you’ll thrive here.\nWe’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.\nAnd 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.\nWhy This Role Stands Out\nHigh Impact: Your work directly supports a widely used application that drives real-time decision-making\nHigh Visibility: Partner with engineering teams and key stakeholders across programs\nCareer Growth: Expand your expertise in large-scale data systems, performance optimization, and advanced SQL engineering\nChallenging Work: Tackle complex data problems, not routine queries\nKey Responsibilities\nDevelop advanced, high-performance SQL queries across large, complex datasets (multi-table joins, window functions, aggregations)\nOptimize query performance using execution plans, indexing strategies, and query refactoring\nEnsure data accuracy and integrity across reporting datasets\nTroubleshoot and resolve data issues across database and application layers\nShape and structure data for efficient and intuitive dashboard visualization\nCollaborate with ETL engineers and dashboard developers to ensure reliable, end-to-end data delivery\nBasic Qualifications\nBachelor’s degree with 8-12 years of experience, or Master’s with 6-10 years of experience\nU.S. Citizenship\n Active TS/SCI with the ability to successfully pass a Polygraph\nExpert-level SQL skills, including:Complex joins across large datasets\nQuery optimization and execution plan analysis\nAggregations, subqueries, and window functions\n\nStrong experience with relational databases (PostgreSQL, MySQL, Oracle, or similar)\nExperience working with large-scale data supporting analytics/reporting\nProficiency in Linux environments\nAbility to work independently and solve complex data challenges\nPreferred Qualifications\nExperience with Grafana or similar visualization tools\nPython for data manipulation (pandas, scripting, automation)\nExperience with materialized views, caching strategies, or query acceleration techniques\nIf 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.\nOriginal Posting:\nOctober 26, 2026For 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.\nPay Range:\nPay Range $107,900.00 - $195,050.00The Leidos pay range for this job level is a general guideline only and not a guarantee of compensation or salary.
