Sr Developer, Application Development

TransUnion is looking for a Senior Java Full Stack Developer with over eight years of experience in designing and delivering scalable, enterprise-grade applications. This hybrid role is part of the TCSVIZ team, which manages four key products: Certified Caller Insights, Robocall Mitigation Insights, TrustID Insights, and Intelligent Call Control portals. The position requires a combination of virtual and in-person work, with a minimum of two days per week onsite at a TransUnion office. The successful candidate will take ownership of the entire software development lifecycle, including architectural design, technical specifications, coding, code reviews, and cloud deployment on AWS or GCP.

Key Responsibilities
Develop production-ready, robust code across the full stack, working with Java/Spring Boot on the backend and modern JavaScript/TypeScript frameworks on the frontend. Deploy, optimize, and manage containerized services on cloud platforms such as AWS or GCP. Lead peer code reviews, enforce best practices, secure coding standards, and maintain high test coverage through unit, integration, and end-to-end testing. Provide technical leadership by mentoring mid-level and junior engineers, resolving complex technical challenges, and driving agile delivery processes. Collaborate closely with DevOps teams to design and maintain automated build, test, and release pipelines that support continuous integration and continuous delivery (CI/CD).

Required Qualifications
A minimum of eight years of full-lifecycle software engineering experience is essential. Strong backend expertise in Java (versions 11, 17, or 21), Spring Boot, Spring Cloud, Hibernate/JPA, and building RESTful or GraphQL APIs is required. Proficiency with modern frontend frameworks such as Angular, React, or Vue.js, along with TypeScript, HTML5, and CSS3, is necessary. Hands-on experience with cloud platforms—either AWS (including ECS, EKS, Lambda, S3, RDS, SQS/SNS) or GCP (GKE, Cloud Run, Cloud Functions, Pub/Sub, Cloud SQL)—is expected. Solid knowledge of relational databases like PostgreSQL, MySQL, or Oracle, and familiarity with NoSQL databases such as MongoDB and Redis, is important. A strong understanding of microservices architecture, distributed systems, event-driven design, and messaging queues like Kafka is required. Proficiency with containerization and orchestration tools including Docker and Kubernetes, as well as CI/CD tools such as Harness, GitLab CI, or Jenkins, is essential. Candidates should demonstrate a commitment to engineering best practices including Test-Driven Development (TDD), Behavior-Driven Development (BDD), clean architecture, SOLID principles, and system design.

Preferred Qualifications and Benefits
Experience with Infrastructure as Code tools such as Terraform, CloudFormation, or AWS CDK is a plus. Cloud certification in AWS or GCP is advantageous. Familiarity with observability and monitoring tools like Prometheus, Grafana, and OpenTelemetry is also preferred. TransUnion fosters a culture that empowers employees to innovate and contribute to meaningful outcomes for communities and customers. The company prioritizes professional growth and work-life flexibility, offering resources that support collaboration and excellence worldwide. Joining TransUnion means working alongside talented professionals on pioneering products and cutting-edge technology as part of the Workforce for Good initiative.
