About The Position

XPECT Solutions is seeking a Senior Solutions Architect – Lead to support our Federal Government Customer with delivering secure, cloud-based mission systems. The Lead Architect will own the end-to-end technical design across full-stack applications, microservices, and AWS infrastructure, setting architectural direction and guiding a team of engineers through delivery. This role spans front-end (React, JavaScript, HTML/CSS), back-end (Java, Spring Boot, Python, Apache Camel, GraphQL), data, and cloud layers — translating mission requirements into scalable, maintainable solutions that meet federal compliance requirements (NIST 800-53, FedRAMP, DHS 4300A). The ideal candidate is a hands-on technical leader who can move fluidly between whiteboard design, code review, and stakeholder briefings, and who has a track record of leading architecture for complex distributed systems in regulated environments. As a Hybrid position, there is an onsite requirement of one day per week.

Responsibilities

Lead the end-to-end architecture for secure, cloud-based mission applications, spanning front-end, back-end, microservices, data, and AWS infrastructure layers.
Define and maintain reference architectures, design patterns, API contracts, and architectural decision records (ADRs) that guide the engineering team and ensure consistency across the program.
Architect microservices-based solutions using Java, Spring Boot, and Apache Camel, with well-defined integration patterns over REST, GraphQL, XML, and JSON.
Direct front-end architecture using React, JavaScript, and HTML/CSS, establishing component standards, state-management patterns, and accessibility/Section 508 compliance.
Design database schemas and data engineering solutions across multiple platforms (relational and NoSQL), including data modeling, performance tuning, and migration strategy.
Architect AWS deployments using EC2, ECS, EBS, RDS Postgres, ALBs, Lambda, S3, and Amazon MQ — defining networking, scaling, resilience, and cost-optimization strategies.
Provide hands-on technical leadership: review code and infrastructure-as-code (Terraform), conduct design reviews, and resolve cross-team architectural issues.
Establish CI/CD and DevSecOps standards in partnership with platform teams, leveraging Git, Jenkins, Terraform, and Vault to automate secure build, deploy, and release workflows.
Embed security and compliance controls (NIST 800-53, FedRAMP, DHS 4300A) into all architectural designs, supporting ATO activities and POA&M remediation.
Mentor and develop senior and mid-level engineers, fostering a culture of technical excellence, code quality, and continuous improvement.
Engage directly with government stakeholders to present architectural decisions, trade-off analyses, and roadmap recommendations, translating technical concepts for non-technical audiences.
Evaluate emerging technologies, conduct proofs-of-concept, and recommend strategic investments aligned to long-term mission needs.
