Description

RVO Health is seeking a high-end Senior Backend Engineer to help identify, remediate, and prevent security vulnerabilities across applications, starting with the Perks application. This is a senior engineering role at the intersection of backend development, cloud infrastructure, application security, architecture, and AI—security remediation is a meaningful part of the work, not exclusively a dedicated security SME role. The engineer will review scanner findings, determine the remediation approach, implement the necessary code/infrastructure/config changes, and validate results using AI-assisted development tools.

Responsibilities

• Design, develop, and maintain backend applications and services using TypeScript and NestJS

• Provide senior-level expertise across backend development, architecture, cloud infrastructure, and application security

• Contribute to application architecture and technical design decisions

• Develop and modify cloud infrastructure using Terraform (infrastructure-as-code)

• Support applications and infrastructure running across Microsoft Azure and AWS

• Review vulnerability findings from application, code, cloud, and infrastructure security scanning tools

• Analyze vulnerabilities and select the appropriate technical remediation strategy

• Implement remediation via application code, Terraform/infrastructure configuration, and cloud configuration changes

• Address vulnerabilities involving dependencies/third-party packages, APIs, authentication/authorization, secrets/credentials, cloud infrastructure/configuration, and application configuration

• Apply patches and other security fixes based on findings

• Work primarily on backend remediation, with UI-related support when necessary

• Partner with engineering, infrastructure, and security teams to drive remediation

• Validate that vulnerabilities are successfully remediated

• Use AI models and AI coding assistants to support development and security remediation

• Help improve secure development and infrastructure practices across teams

Benefits

• Senior-level opportunity to combine backend engineering, cloud infrastructure, application security, and AI-assisted workflows

• Remote 6-month contract with potential to extend
