Software​/Analytics Engineer

Description

Must have an active DOE Q or DOD Top Secret clearance. Active, meaning the individual granted a clearance is briefed and currently occupies a position for which the clearance is required.

Leidos is hiring a Software/Analytics Engineer to support a Federal Program Office within the Stockpile Sustainment Directorate for the National Nuclear Security Administration (NNSA). The successful candidate will serve as a senior technical contributor responsible for designing, developing, and sustaining advanced analytical software applications that directly support decision‑making, production planning, and strategic analysis across the NNSA. The role provides the technical backbone for mission‑critical tools—including applications such as Enterprise Capacity Analysis (ECA)—and supports long‑term supply‑versus‑demand assessments, scenario evaluations, and enterprise‑wide planning activities.

We are looking for an experienced software engineer with a strong background in Python‑based analytical application development, data engineering, database interaction, and user‑facing analytical interfaces. The successful candidate excels at transforming analytical workflows into maintainable, scalable, and secure production software. They will collaborate extensively with federal and support staff, analysts, and leadership across the Nuclear Security Enterprise (NSE) to define requirements, improve analytical tools, and deliver sustainable software solutions that strengthen enterprise decision support.

The successful candidate will integrate domain‑specific modeling and analytical concepts into robust software systems, enabling analysts and senior leadership to rapidly explore data, compare scenarios, and generate actionable insights. The work directly supports national defense objectives by improving the quality, reliability, and accessibility of enterprise analytical capabilities.

Location:

This position will be onsite in Albuquerque, NM (preferred) or Washington, DC.
