• Observability and networking: Prometheus, Grafana, OpenTelemetry, Elasticsearch, VictoriaMetrics, gNMI, SNMP, NETCONF, and vendor APIs

Responsibilities

• Lead the architecture, design, implementation, and operation of complex backend Python services, APIs, and data-processing workflows.
• Design asynchronous and event-driven integrations and establish scalable patterns for API and event contracts.
• Make and document technical decisions that balance delivery speed, operational risk, maintainability, scalability, and long-term platform direction.
• Lead design and code reviews, establish practical standards for Python, testing, security, observability, and documentation.
• Improve CI/CD practices and partner with SRE and DevOps on container images, Kubernetes deployments, and infrastructure as code.
• Define production-readiness expectations through service-level indicators, metrics, dashboards, alerts, performance testing, capacity analysis, and resilience testing.
• Lead complex incident investigations, address root causes and corrective actions.
• Coordinate technical dependencies across internal projects and platforms.

Qualifications

• Advanced Python development experience, including structuring, testing, packaging, and operating long-lived backend applications.
• Experience leading the design or delivery of distributed services, APIs, data platforms, network tools, or automation systems.
• Strong knowledge of relational databases, SQL, data modeling, transaction behavior, indexing, and controlled schema migrations.
• Hands-on experience with Linux, Docker, containerized services, CI/CD pipelines, and automated software-quality and security controls.
• Experience implementing production observability and diagnosing complex problems across application code, infrastructure, databases, messaging systems, and external dependencies.
• Demonstrated ownership of production software through delivery, deployment, monitoring, incident response, and continual improvement.
• Demonstrated technical leadership through architecture, mentoring, project leadership, design reviews, code reviews, or cross-team influence.

Preferred Qualifications

• Experience developing software solutions within the telecommunications industry.
• Experience with FastAPI, Pydantic, SQLAlchemy, Alembic, gRPC, Protobuf, or comparable technologies.
• Experience with NATS, Kafka, RabbitMQ, Redis, or another production messaging platform.
• Experience with Kubernetes, Helm, Terraform, GitLab CI, GitOps, or progressive-delivery tooling.
• Experience with Prometheus, Grafana, OpenTelemetry, Elasticsearch, Loki, VictoriaMetrics, service-level objectives, or advanced performance and resilience testing.
• Experience with network telemetry protocols such as gNMI, SNMP, or NETCONF.
• Experience processing high-volume operational telemetry or building software for NOC, SRE, infrastructure, network-engineering, or telecommunications environments.

Education And Experience

• Minimum of seven (7) years of professional software development experience, or equivalent demonstrated experience designing and operating complex production systems.
• Bachelor's degree in Computer Science, Information Technology OR equivalent relevant professional experience.
