Job Family : IT Architecture/Cloud Travel Required : None Clearance Required : Ability to Obtain Public Trust Job Description Summary The Senior Technical Lead / Solution Architect will provide senior, hands-on technical leadership for a large-scale agile software development and platform modernization program supporting a large Federal contract. Working under the architectural direction of the integrated architecture team, this role will translate approved architectures, designs, patterns, and standards into actionable implementation guidance for multiple workstreams, vendors, and delivery teams. The Senior Technical Lead / Solution Architect will collaborate with the architects on solution design, ensure teams implement solutions as intended, verify adherence to architectural and engineering standards, and identify and escalate deviations or risks. The role will help ensure delivered capabilities are secure, scalable, maintainable, interoperable, and aligned with the program’s target architecture. What You Will Do : We are seeking a seasoned Senior Technical Lead / Solution Architect to lead the technical implementation of a platform modernization effort. Working within the direction and guardrails established by the integrated architecture team, this individual will collaborate on solution designs, communicate approved designs to delivery teams, provide day-to-day technical guidance, and oversee implementation across multiple workstreams, vendors, and Scrum teams while supporting continuity of critical legacy operations throughout the transition. The Senior Technical Lead / Solution Architect will be accountable for turning approved architecture into consistent, high-quality implementation. This leader will partner with the integrated architecture team to clarify designs, assess implementation options, and surface delivery considerations while ensuring engineering teams follow established architecture decisions, interface contracts, data standards, security requirements, and development practices. The role requires strong technical judgment, hands-on delivery leadership, and the ability to coach teams, review technical work, resolve implementation issues, and escalate proposed deviations for architectural review and approval. Serve as the senior implementation-focused technical lead for a large-scale platform modernization program delivered through iterative agile execution. Work under the direction of the integrated architecture team and collaborate with them to refine solution designs, evaluate implementation considerations, and translate approved architecture into actionable technical guidance. Communicate approved solution designs, reference architectures, design patterns, data standards, interface contracts, and engineering guardrails to development and vendor teams. Provide day-to-day technical leadership to engineers implementing APIs, data exchanges, shared services, workflow automation, cloud-native solutions, DevSecOps capabilities, and incremental migrations. Review detailed designs, code, configurations, interfaces, and technical deliverables to verify that implementation aligns with approved architecture and established engineering standards. Establish practical implementation checkpoints, code and design review practices, technical acceptance criteria, and traceability mechanisms that reinforce architectural compliance throughout delivery. Identify architectural deviations, implementation risks, technical debt, and standards violations; work with teams on remediation and escalate exceptions to the integrated architecture team for decision and approval. Coordinate technical implementation across Scrum teams and vendors to maintain consistency in service boundaries, interfaces, data handling, security controls, reusable components, and shared platform capabilities. Resolve complex implementation issues and cross-team dependencies while protecting the intent of the approved architecture and engaging the architects when design-level decisions are required. Mentor technical leads and engineers, strengthen engineering discipline, and promote consistent use of approved patterns, tools, and development practices. Provide clear implementation status, risks, compliance concerns, and recommended corrective actions to the Enterprise and Data Architects, program leadership, Product Owners, and delivery stakeholders.
