## About the Role

* 6-8+ years of professional Java software development experience, including significant hands-on work building and supporting production applications and APIs.

 * Excellent working knowledge of the Spring Framework, including Spring Boot, Spring Security, and Spring Data, along with the relevant underlying skills (dependency injection, AOP, transaction management, and JPA/Hibernate).

 * Strong AWS expertise with hands-on experience in EC2, API Gateway, S3, and Lambda, plus working knowledge of IAM, VPC, CloudWatch, and related services.

 * Demonstrated ability to independently own CI/CD pipelines, including setup, maintenance, and troubleshooting of build and deployment failures.

 * Strong track record of building secure applications and APIs, with familiarity with the OWASP Top 10 and API Security Top 10.

 * Experience supporting mission-critical systems, including on-call or production incident response, performance tuning, and root-cause analysis.

 * Solid software engineering fundamentals: version control (Git), automated testing, code review, and design patterns.

 * Ability to work independently with minimal day-to-day direction while coordinating effectively with cross-functional teams.

 * Strong written and verbal communication skills, including the ability to explain technical tradeoffs to non-technical stakeholders.

 * Nice to have:

 * AWS Certification (e.g., AWS Certified Developer - Associate/Professional, AWS Certified Solutions Architect - Associate).

 * Experience with containerization and orchestration (Docker, Amazon ECS/EKS, Kubernetes).

 * Experience with infrastructure-as-code (Terraform, AWS CloudFormation, or AWS CDK).

 * Experience with messaging and event-driven architectures (SQS, SNS, Kafka, EventBridge).

 * Experience in a regulated industry (healthcare, financial services, government) with exposure to HIPAA, SOC 2, PCI-DSS, or similar frameworks.

## Description

UST is searching for a Senior Java Developer to independently develop, support, and maintain secure Java applications and APIs hosted on AWS.

What You'll Do

 * Independently design, develop, and maintain Java applications and RESTful APIs using the Spring Framework (Spring Boot, Spring Security, Spring Data, and related modules) hosted on AWS.

 * Build and support secure APIs with strong authentication and authorization (OAuth2/OIDC, JWT), input validation, secrets management, and encryption in transit and at rest.

 * Design and operate AWS-hosted services using EC2, API Gateway, S3, Lambda, and other relevant managed services, including IAM, VPC networking, load balancing, and CloudWatch monitoring.

 * Own CI/CD pipelines for build, test, and deployment (e.g., Jenkins, GitHub Actions, AWS CodePipeline/CodeBuild, or similar), and independently diagnose and resolve pipeline failures.

 * Provide production support for business-critical applications, including incident triage, root-cause analysis, performance tuning, and post-incident remediation.

 * Implement logging, auditing, and monitoring for applications and APIs to support traceability, compliance, and rapid incident response.

 * Write clean, well-tested code, including unit, integration, and contract tests, and enforce code quality through peer reviews and automated checks.

 * Participate in security reviews, threat modeling, and vulnerability remediation, and keep dependencies and runtime environments patched.

 * Mentor junior and mid-level engineers on Java, Spring, AWS best practices, and secure coding standards.

 * Document architecture, deployment procedures, and operational runbooks.
