Job description

• The project is focused on improving the security, release reliability, maintainability, and operational resilience of business-critical banking applications.
• Forward Deployed Engineers will conduct targeted, hands-on engagements with development teams that are facing challenges with vulnerability remediation, automated testing, legacy technology, production stability, or achieving a safe and rapid release cadence.
• The role combines senior software engineering, DevOps, SRE, test automation, application security, and legacy modernization. Approximately 70% of the work involves hands-on coding and configuration.
• The technical scope includes building effective automated test suites, remediating security vulnerabilities, performing dependency and reachability analysis, upgrading Java and NPM runtimes, modernizing Spring and legacy middleware applications, improving CI/CD pipelines, containerizing applications, automating deployments, and introducing standard observability and resilience patterns.
• The Expert FDE is expected to lead complex engagements, work directly with development and client stakeholders, define the technical remediation approach, implement critical changes personally, and enable client teams to maintain the improved engineering practices.

Responsibilities

• Collaborate directly with development teams to identify and resolve issues related to testing, security, release, deployment, resilience, and legacy technologies.
• Review application code, dependencies, test coverage, runtime configurations, deployment processes, logs, monitoring systems, and CI/CD pipelines.
• Write, debug, test, review, and enhance production application code and configurations.
• Develop and maintain automated unit, integration, component, regression, and deployment smoke tests.
• Apply Test-Driven Development practices and select appropriate testing approaches with guidance as needed.
• Source test data and apply masking techniques to protect sensitive information in lower environments.
• Investigate vulnerabilities and dependency risks, identify root causes, implement secure remediation, and conduct regression testing.
• Upgrade Java/JVM or NPM runtimes, Spring components, libraries, dependencies, base images, operating systems, and installed software.
• Assist in implementing automated and continuous dependency updates using Renovate or comparable tools.
• Support modernization efforts for legacy applications and middleware stacks, including WebSphere or WebLogic when applicable.
• Containerize applications using Docker and deploy or support them on OpenShift platforms.
• Enhance Git workflows, branch management, pull requests, and code-review processes.
• Implement and improve CI/CD pipelines, automated quality gates, deployment validation, and rollback procedures.
• Support application and environment automation through Ansible or equivalent tools.
• Apply secure coding patterns and adhere to standards for secrets management, authentication, authorization, and handling sensitive data.
• Improve structured logging, exception handling, health checks, metrics, tracing, dashboards, and operational alerts.
• Support highly available and resilient deployment strategies.
• Troubleshoot production and non-production issues using code analysis, SQL, logs, metrics, traces, and diagnostic tools.
• Communicate progress, risks, technical decisions, blockers, and dependencies to engineering, security, architecture, operations, project management, and client stakeholders.
• Document implemented solutions and facilitate knowledge transfer to development and support teams.
• Own a defined technical workstream from assessment and implementation through testing, deployment, and stabilization.
