C Mack Solutions LLC•Ashburn, VA

1d•$150,000 - $175,000•Hybrid

About The Position

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.

Requirements

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

Nice To Haves

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

Responsibilities

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
