C. Mack Solutions is seeking a Product Architect with strong full-stack development experience to join our team and support a complex program providing Agile development, operations, and maintenance for critical systems on a mission-critical Federal Government program. This is primarily a hands-on development role: you'll build and maintain full-stack features across the front end (React, TypeScript, JavaScript) and back end (Java/Spring Boot, PostgreSQL, AWS), while also taking on meaningful technical leadership within your product team — helping shape implementation approach, reviewing code, mentoring less experienced developers, and representing your team's work to stakeholders. This is a mid-to-senior individual-contributor role with room to grow into more leadership over time, not a full enterprise-architecture ownership position; day to day, most of your time will be spent writing and reviewing code.

As a Product Architect, here's what you'll be doing:

• Design, build, and maintain full-stack features end to end — from React/TypeScript front-end components to Java/Spring Boot services and PostgreSQL data models
• Actively participate in Agile ceremonies, including sprint planning, breaking stories into tasks, demos to the Product Owner, and retrospectives
• Write clean, tested, secure, maintainable code, and help ensure your team's overall code quality through code reviews
• Collaborate with the SecDevOps team to build, onboard, and maintain applications on cloud-based infrastructure (AWS)
• Work with business analysts and the Product Owner to translate business requirements into concrete, well-scoped tasks for the team
• Take on day-to-day technical leadership within your product team — reviewing pull requests, helping remove blockers, and providing guidance and mentoring to less experienced developers
• Contribute to technical documentation for the features and services you build, including design notes and diagrams
• Flag technical risks, quality concerns, or architectural questions that arise in your area of ownership to the broader technical leadership
• Collaborate with Developers, Program Managers, Testers, UI/UX, and Production Support Engineers to deliver solutions iteratively
• Occasionally represent your team's work in stakeholder demos and updates
• Stay current with relevant industry trends and technologies

You must live within the DC, MD, VA area.

U.S. Citizenship is required. Candidate must have an Active CBP Public Trust clearance.

• 7+ years of overall software development experience, with hands-on full-stack development as a developer, and some experience (or clear readiness to take on) technical/project leadership within a team
• A bachelor's degree in computer science, software engineering, or a related field
• Hands-on, production experience with Java (Spring/Spring Boot), React, TypeScript, JavaScript, and PostgreSQL
• Proficiency with browser technologies such as HTML, HTTP, and CSS, and a JavaScript framework such as Kendo UI
• Strong working knowledge of design patterns, object-oriented programming (OOP), and other software design practices that produce modular, maintainable systems
• Experience with RESTful APIs — designing, implementing, and integrating APIs securely and efficiently
• Experience with relational databases (for example, PostgreSQL), data modeling, and data storage best practices
• Experience with cloud platforms (for example, AWS) and a working understanding of distributed-system concepts such as scalability and fault tolerance
• Familiarity with common architectural styles (client-server, microservices, event-driven, layered) and their trade-offs
• Experience with DevOps practices, including CI/CD tools such as Harness, Jenkins, or GitLab
• Experience with containerization (Docker) and orchestration tools (Kubernetes)
• Understanding of common software security vulnerabilities and mitigation strategies (input validation, secure coding practices, encryption)
• Professional experience working within cross-functional Agile/Scrum teams
• Able to work a hybrid schedule with an on-site requirement of 1–2 days a week in Ashburn, VA

Preferred Skills and Experience:

• Experience with TypeScript at scale, Postgres Streams, WebRTC, geospatial software, or generative AI integration (for example, Gemini) — exposure to one or more of these is valuable given this program's application portfolio
• Experience migrating legacy applications to a microservices architecture in the cloud
• Prior experience as a technical lead for a product team, or clear interest in growing into that scope
• Experience contributing to (not necessarily owning) enterprise architecture standards
• Skills in analyzing and optimizing software performance (profiling, benchmarking, code optimization)
• Experience with baseline management and version-control/merge best practices
• AWS Certified Solutions Architect or Google Cloud Professional Cloud Architect certification a plus
• Excellent verbal and written communication skills, with the ability to explain technical topics clearly to non-technical stakeholders
• Strong problem-solving skills, with the ability to analyze complex issues and develop practical solutions
