Position Summary
We are looking for a full-stack engineer with strong Python or Java experience to help modernize our backbone voice infrastructure. The resource will design and build cloud-native services and tooling on AWS, run workloads on Kubernetes, and implement Infrastructure-as-Code and Configuration-as-Code with Terraform and GitOps. This work will enable resilient, observable, and secure voice services at scale, partnering closely with voice and/or network engineering teams.
Scope of Work to Be Performed
• Design, build, and maintain microservices and APIs in Python or Java to support provisioning, routing, monitoring, and control-plane functions for backbone voice services.
• Develop web UIs and dashboards (e.g., React or Angular with TypeScript) for self-service configuration, operations, and observability.
• Containerize and operate services on Kubernetes (preferably EKS), including Helm charts and/or Kustomize, autoscaling, RBAC, and workload security.
• Implement Infrastructure-as-Code using Terraform (modular patterns) for AWS networking, EKS, IAM, compute, storage, and observability stacks.
• Adopt Configuration-as-Code and GitOps for Kubernetes (e.g., Helm, Kustomize, Argo CD/Flux) to enable versioned, auditable rollouts of services and network configurations.
• Build event-driven and streaming integrations (e.g., Kafka and/or SQS) to capture call events, metrics, and operational signals for real-time insights.
• Partner with voice and network engineers to integrate with SIP and/or Clients, PBX and/or call recording, and voice QoS (jitter, packet loss, MOS), implementing secure signaling and/or media (TLS and/or SRTP).
• Establish CI and/or CD pipelines (e.g., GitHub Actions, Jenkins, GitLab CI), automated testing (e.g., unit, integration, contract, and/or load), and security scanning.
• Implement end-to-end observability, including but not limited to:
o Metrics,
o Logs,
o Tracing (e.g., Prometheus, Grafana, and/or OpenTelemetry),
o SLOs and/or SLIs, and/or
o Actionable alerting.
• Embed security best practices, including but not limited to:
o IAM least privilege,
o Secret management,
o mTLS,
o Network segmentation,
o Audit trails, and/or
o Compliance-by-design.
• Contribute to SRE practices, including but not limited to:
o Incident response,
o Root-cause analysis,
o Capacity planning,
o Service hardening, and/or
o On-call participation.
