Interested in expanding your technical impact. Love solving tough problems. Come architect the answers.

Leidos has an immediate opening for a Solutions Architect to join our Mission Solutions team within the Intelligence Sector and serve as a key technical contributor within the CTO organization.

This role is for technically curious problem-solvers who want to tackle challenges bigger than any one technology or system. If you enjoy understanding how secure networks and systems work, identifying vulnerabilities, defending against cyber threats, or solving complex security challenges, this role offers an opportunity to think bigger. Apply your technical experience to architect solutions that bring together cybersecurity, network and systems engineering, communications, AI, and emerging technologies to solve critical mission problems.

We're looking for someone with a strong technical foundation, curiosity, systems thinking, and the ability to learn. You don't need to know every technology or mission domain. You just need to be comfortable asking questions, working with subject matter experts, evaluating alternatives, and turning an ambiguous problem into a well-reasoned technical approach.

This position reports to the CTO for the Mission Solutions Business Area.

• Solve Complex Technical Problems: Help analyze mission needs and requirements, break down complex problems, and contribute to well-reasoned solution approaches.

• Contribute to Capture and Proposal Efforts: Support capture and business development activities by contributing to technical narratives, whitepapers, concept papers, and proposal sections under the guidance of experienced solution architects.

• Research and Evaluate Emerging Technologies: Assist in evaluating new capabilities such as AI-driven analytics, cyber resilience frameworks, cyber security operations, communications architectures, automation tools, or modeling and simulation technologies, and help assess how they may fit into mission solutions.

• Communicate Technical Concepts: Participate in technical discussions and briefings, helping articulate solution approaches to engineers, program teams, and leadership.

• Collaborate Across Domains: Work with SMEs across various emerging technical domains to build cohesive, multi-domain solutions.

• Strong analytical and problem-solving skills, with the ability to interpret requirements and contribute to well-reasoned technical approaches.

• Experience working within or supporting the Intelligence Community (IC), with an understanding of its missions, operational environments, and technical challenges.

• Experience communicating technical concepts clearly to engineers, analysts, and program teams through briefings, documentation, or design discussions.

• Ability to research unfamiliar technical areas, learn new concepts quickly, synthesize information from multiple sources, and apply that knowledge to solving technical problems.

• Familiarity with systems engineering practices, enterprise architecture concepts, or mission communications environments.

• Experience contributing to technical documentation such as design artifacts, concept papers, architecture discussions, whitepapers, or proposal sections.
