Lead Software Engineer

About the role

We are seeking a highly skilled and experienced Lead Software Engineer to join the Digital Onboarding technology team. This role will focus primarily on backend application development, APIs, integration services, and cloud-native engineering capabilities that support Digital Onboarding applications and customer onboarding workflows.

The ideal candidate will have strong hands-on experience with Java, Spring Boot, REST APIs, microservices, and AWS, with the ability to lead technical delivery, mentor engineers, troubleshoot complex application issues, and ensure high-quality production releases. A strong focus of this role is building secure, vulnerability-free code and actively addressing OWASP Top 10, HackerOne, WAF, penetration testing, static scan, dynamic scan, open-source dependency, and other application security findings.

Responsibilities

• Lead backend development for Digital Onboarding applications, APIs, customer workflows, and integration services.
• Design, develop, test, debug, and maintain scalable backend services using Java, Spring Boot, REST APIs, microservices, and cloud-native architecture patterns.
• Build and support secure, resilient, and high-performing services deployed on AWS.
• Participate across the full software development lifecycle, including requirements analysis, solution design, development, code reviews, testing, deployment, production support, and continuous improvement.
• Troubleshoot and debug software defects, technical issues, production incidents, integration failures, performance problems, and security vulnerabilities.
• Implement unit tests, integration tests, API validation, and automated checks to improve software quality and reduce regression risk.
• Prioritize work across feature delivery, defect resolution, technical debt, security remediation, and production support needs.
• Stay current with evolving backend technologies, AWS services, secure coding practices, vulnerability management expectations, and AI-assisted engineering tools.

Requirements

• 7+ years of experience designing, developing, and supporting enterprise software applications.
• Strong hands-on experience with Java, Spring Boot, REST APIs, microservices, and backend application development.
• Strong experience building secure backend applications with a focus on vulnerability-free code, secure coding practices, and application security remediation.
• Experience remediating findings related to OWASP Top 10, HackerOne, penetration testing, static application security testing, dynamic application security testing, dependency vulnerabilities, and secure configuration issues.
• Experience with AWS services and cloud-native application development.
• Experience with AWS capabilities such as ECS/EKS, Lambda, S3, API Gateway, CloudWatch, IAM, Secrets Manager, or related services.
• Strong understanding of API design, distributed systems, service integration, authorization, authentication, secrets handling, input validation, error handling, logging, observability, and production support.
• Experience with relational databases, SQL, persistence frameworks such as JPA/Hibernate, and application-level data modeling.
• Experience with Git-based workflows, Maven or Gradle, CI/CD pipelines, automated builds, release processes, and deployment automation.
• Experience writing unit tests and integration tests using JUnit, Mockito, or similar frameworks.
• Practical understanding of secure software delivery, including code reviews, dependency management, vulnerability scanning, remediation tracking, and retesting.
• Strong debugging, troubleshooting, and problem-solving skills in complex application environments.
• Experience working in Agile teams and collaborating with product owners, QA, architecture, DevOps, AppSec, and business stakeholders.
• Ability to mentor engineers, influence technical direction, and communicate technical concepts clearly to both technical and non-technical stakeholders.
