Detroit, MI (Hybrid – 3 Days Onsite)
Contract-to-Hire

We are seeking a Principal Full Stack Engineer to provide technical leadership for a large-scale, high-volume enterprise platform undergoing significant modernization and cloud transformation efforts.

This role is ideal for a hands-on technical leader who enjoys solving complex engineering challenges, mentoring developers, and driving modernization initiatives across backend services, APIs, databases, and cloud infrastructure. While this is a full stack position, the primary focus is on backend architecture, integrations, and platform scalability.

What You'll Do

• Serve as the technical leader and subject matter expert across multiple engineering teams.
• Drive modernization efforts across Java services, APIs, databases, messaging platforms, and cloud infrastructure.
• Lead design and implementation of scalable microservices and enterprise integration solutions.
• Partner with engineering teams to improve platform resiliency, performance, scalability, and maintainability.
• Define and promote engineering best practices, coding standards, and architectural patterns.
• Mentor engineers through technical leadership, design reviews, and hands-on collaboration.
• Help guide the organization's migration from on-prem/containerized environments to AWS cloud solutions.
• Collaborate with Product, Architecture, Security, and Engineering stakeholders to solve complex business and technical challenges.

Required Qualifications

• 10+ years of software engineering experience with increasing technical leadership responsibilities.
• Strong hands-on experience with Java and modern backend development frameworks.
• Experience designing and building microservices-based applications.
• Strong experience with RESTful API design, development, and integration.
• Deep understanding of SQL and enterprise database technologies, including Oracle.
• Experience working with messaging and event-driven architectures (Kafka or similar technologies).
• Proven ability to lead technical initiatives across multiple teams without direct people management responsibility.
• Strong communication skills with the ability to influence technical direction and mentor engineers.

Preferred Qualifications

• Experience with AWS cloud technologies and cloud migration initiatives.
• Experience with OpenShift, Kubernetes, Docker, or containerized environments.
• Familiarity with identity and access management solutions such as Okta.
• Exposure to Angular and/or React applications.
• Experience working in large-scale, high-availability enterprise environments.
• Experience with multi-tenant or white-label application architectures.
