Our Applications business unit focuses on delivering a suite of advanced communication tools designed to enhance customer engagement. From cloud contact centers to feature-rich unified communications solutions, our Applications team is dedicated to providing businesses with the tools they need to streamline operations and improve customer experiences.
Authentication and identity are the front door to every Vonage product — and the Cerberus team is the engineering team that keeps that door secure, reliable, and scalable for hundreds of thousands of business users worldwide. Sitting at the heart of the Vonage Business Communications and Vonage Contact Center platforms, we own the full identity stack — OAuth 2.0 / OIDC, SSO, MFA, SCIM, RBAC/ABAC, fraud detection, and more — processing hundreds of thousands of requests per minute in production. This is not a supporting role; it is core infrastructure where a single decision can affect the security and availability of Vonage's entire product suite. As a Software Engineer joining a team of 6 senior engineers, you will take end-to-end ownership of mission-critical microservices, contribute to the modernization of the VCC identity platform, and help shape the technical direction of a fast-moving, security-first team — with real impact visible at scale from day one.
Design, develop, and maintain authentication and authorization microservices (backend-heavy, full-stack) serving the VBC and VCC platforms
Take full ownership of features end-to-end — from requirement kick-off and solution design through implementation, code review, testing, production deployment, and post-deploy monitoring
Participate actively in Agile ceremonies — daily stand-ups, sprint planning, retrospectives, and design discussions — contributing concrete technical insights and surfacing risks early
Manage production deployments using CI/CD pipelines (GitHub Actions / Bolt), including smoke tests, E2E test execution, log analysis (Kibana / Grafana), and incident response
Implement and maintain security-critical flows including OAuth 2.0, OIDC, SAML 2.0, JWT, MFA, passkey/FIDO, SCIM, and inter-service authentication patterns
Write and maintain technical documentation — architecture decision records, playbooks, runbooks, and knowledge-transfer materials
Participate in on-call rotation (OpsGenie), responding to production alerts, investigating issues, and driving root cause analysis
Leverage AI-assisted development tools (e.g., GitHub Copilot, Claude Code) to enhance personal productivity, code quality, and delivery speed.
Required:
Full-Stack developer with a strong server-side orientation — comfortable owning backend services while able to contribute to frontend when needed
Proficiency in Node.js — ability to design, build, and maintain scalable backend services in JavaScript/TypeScript
Hands-on AWS experience — working knowledge of core AWS services (EKS/Kubernetes, EC2, Secrets Manager, WAF, S3, CloudFront, Lambda, ElastiCache)
Microservices architecture — experience designing and operating distributed microservice systems, including service-to-service communication, event-driven patterns (Kafka), and API design
PostgreSQL / relational databases — proficiency in schema design, query optimization, and database best practices
AI-augmented development — active user of AI coding assistants (GitHub Copilot, Claude Code, Cursor, or equivalent) as part of everyday development workflow
Experience we consider a plus:
NestJS — experience building backend services with the NestJS framework (the team's emerging standard for VCC services)
DevOps practices — familiarity with CI/CD pipelines, GitHub Actions, infrastructure-as-code (Terraform / CloudFormation / Helm charts), and Kubernetes manifests
