Product Architect

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, Type Script, 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.

• Design, build, and maintain full-stack features end to end — from React/Type Script 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 Sec Dev Ops  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, Type Script, 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 (e.g., PostgreSQL), data modeling, and data storage best practices
• Experience with cloud platforms (e.g., 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 Dev Ops practices, including CI/CD tools such as Harness, Jenkins, or Git Lab
• Experience with containerization (Docker) and…
