Job description

Description

Leidos is seeking a Senior AI Platform Engineer to join our DCSB Artificial Intelligence & Agent Development team supporting the U.S. Army C5ISR Center.

In this role, you will lead the technical strategy for building and accrediting a secure agentic AI platform within AWS GovCloud (IL5). You will combine deep cloud and platform engineering expertise with DoD security accreditation, RMF, ATO/cATO, and DevSecOps practices to ensure AI capabilities can be securely deployed into operational environments.

This is not a traditional AI/ML development position. Your primary challenge will be creating a secure, observable, and accreditable platform on which agentic AI capabilities can operate.

You will serve as a key technical interface between platform engineering, security engineering, ISSO/ISSM personnel, and Authorizing Official (AO) stakeholders. You will also help establish secure engineering patterns so accreditation is built into the platform from the beginning rather than addressed after development.

Location: Remote, however must be within commuting distance of Adelphi, MD to report on site as needed.

Clearance: U.S. citizenship with an active Secret Clearance and ability to obtain Top Secret clearance.

Primary Responsibilities:

• Lead the technical accreditation strategy for the agentic AI platform, including security controls for models, tools, and agent-to-agent interactions.
• Develop and maintain technical artifacts supporting ATO and continuous ATO (cATO), including control narratives, architecture diagrams, data flows, boundary definitions, POA&M inputs, and security scan evidence.
• Partner with security engineering, ISSO/ISSM personnel, and AO stakeholders to translate complex AI and cloud architectures into evidence supporting authorization decisions.
• Design, build, and operate a secure AWS GovCloud IL5 platform supporting agentic AI workloads.
• Deploy and manage containerized workloads using Kubernetes and Docker, including scaling, observability, resiliency, and failure recovery.
• Build and maintain CI/CD pipelines and Infrastructure as Code (IaC) using Platform One and technologies such as Terraform or CloudFormation.
• Support container hardening, image accreditation, and secure software delivery practices.
• Integrate Amazon Bedrock and other authorized AI/ML services, managing IAM, network boundaries, service quotas, and data flow controls.
• Implement logging, tracing, monitoring, auditability, and cost attribution for agent and tool activity.
• Apply MLOps practices including model and prompt versioning, deployment gating, monitoring, and rollback.
• Mentor engineers on secure, accreditable architecture and development practices.
• Develop and execute the platform technical roadmap aligned with program and mission objectives.

• Bachelor's or Master's degree in Computer Science, Engineering, Data Science, Mathematics, or a related technical field.
• 8+ years of hands-on experience in cloud, platform, DevOps, or MLOps engineering.
• U.S. citizenship with active Secret clearance with the ability to obtain and maintain Top Secret.
• Demonstrated experience supporting a system through formal security accreditation/RMF, including substantial contributions to security control documentation and direct interaction with security or authorization stakeholders.
• Experience operating within a DoD or federal accredited cloud environment, such as IL4/IL5, FedRAMP Moderate/High, or comparable.
• Hands-on experience with AWS, Kubernetes, Docker, and Infrastructure as Code.
• Experience designing, building, and maintaining CI/CD pipelines.
• Proficiency in Python.
• Working knowledge of how ML/LLM workloads are deployed, scaled, secured, and monitored.
• Strong communication skills with the ability to explain and defend technical architecture and security decisions.

• Active TS/SCI clearance.
• Experience supporting national security, defense, or DoD environments.
• Direct experience with continuous ATO (cATO), continuous monitoring, and pipeline-based security evidence.
• Experience with Platform One, Iron Bank, or Big Bang.
• Experience with AWS Bedrock, Bedrock AgentCore, SageMaker, or similar managed AI/ML services.
• Experience securing or accrediting systems involving LLMs, autonomous decision logic, agentic AI, or dynamic service interactions.
• Experience with cybersecurity operations, security engineering, or DoD cyber environments.
• DoD 8570 IAT Level II certification or equivalent.

How to prepare and behave

This is editorial guidance, not information from the employer.

• Read the whole description and match your examples to its requirements; use the same words the posting uses where they are true for you.
• Research the employer before the interview: what it does, who its customers are and recent news; prepare two or three questions about the work.
• Arrive early (or log in early for a video call), dress one step above the daily dress code, and test your camera and audio beforehand.
• Answer with short stories: the situation, what you did and the result. Give numbers when you have them and never invent them.
• 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.
• Send a short thank-you message within a day, mentioning one thing you discussed.
• The listing mentions a remote or flexible location. Confirm with the employer whether remote work applies to your state: taxes, licensing and benefits can depend on where you live.
• Have code, data work or projects you can show, and be ready to think aloud: many technical interviews test how you reason, not only the answer.

• U.S. Department of Labor: Wage and Hour Division

The city

The job is in Hyattsville, MD. Below is what the official statistics say about living and working there.

How Hyattsville compares. Among the 80 largest places in Maryland, Hyattsville is #67 by population, #15 for remote work (#1 = most), #64 for homeownership (#1 = highest), #63 for long commutes (#1 = fewest). Its county, Prince George's County, is #6 of 24 counties for average pay ($73,373).

The place in numbers

Hyattsville has 20,966 residents (ACS 2020–2024), about 0.3% of the population of Maryland. It covers 3 square miles of land, which works out to roughly 7,751 people per square mile. The median age is 35.6, 10% younger than the state median (35.6 against 39.4).

Housing

The median gross rent is $1,835 a month (rent plus utilities), 8% above the state median ($1,835 against $1,705). Over a year that is 24.0% 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 $481,500, which is 5.2 times the median household income ($91,941); a ratio above 5 usually means buying is out of reach without savings or a second income. 48.4% of households own their home, 28% below the state average (48.4% against 67.6%). A low ownership share points to a rental-heavy market with more apartments and shorter stays.

Work and pay

The Washington-Arlington-Alexandria, DC-VA-MD-WV metropolitan area has 3,136,190 jobs in the BLS wage survey, and the median pay across all occupations is $71,060 a year, 39% above the national median ($71,060 against $50,980). The biggest occupation groups are business and financial operations (369,190 jobs, median $105,260); management (319,760 jobs, median $165,010); office and administrative support (290,050 jobs, median $53,250). The area is most specialised in legal (2.6 times) and computer and mathematical (2.2 times), where the share of workers is well above the national share. The best-paying groups with at least 5,000 jobs are legal ($175,070) and management ($165,010). In 2026M09 the unemployment rate of Prince George's County was 4.0%. 75.4% of residents aged 16 and over are in the labour force. The city lies in Prince George's County; its jobs, pay by industry and GDP are on the county page.

Getting around

Among workers, 51.8% drive alone, 10.5% use public transit, 2.9% walk, 25.9% work from home. 28.8% of workers commute 45 minutes or more, 19% above the state average (28.8% against 24.2%). Remote work is more common than in the state as a whole, which widens the set of employers a resident can work for without moving.

People and education

50.7% of adults aged 25 and over hold a bachelor's degree or higher, 17% above the state share (50.7% against 43.5%). 37.2% of residents were born outside the United States, 124% above the state share (37.2% against 16.6%). The poverty rate is 11.6%, 23% above the state rate (11.6% against 9.4%).

Climate

The warmest month is Jul, averaging 78°F (25.8°C), and the coolest is Jan at 32°F (0.1°C). About 1,152 mm (45 inches) of precipitation falls in a year; Jun is the wettest month (118 mm) and Jan the driest (67 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.
