-
- Ensure systems are observable, secure, and compliant, incorporating metrics, logs, and alerting into every layer.

- Mentor and support engineers on your immediate team, helping them grow in their technical careers and navigate complex challenges.
REQUIREMENTS

- Strong proficiency in Go and Python for building backend services and automation tools.
- Proven experience designing, deploying, and operating cloud-native systems (e.g., Kubernetes, service meshes, autoscaling infrastructure).
- Deep understanding of distributed systems, networking, caching, and resilient design patterns.
- Expertise in CI/CD pipelines, containerization (Docker), and orchestration (Kubernetes).
- Experience with observability tooling (e.g., Prometheus, Grafana, OpenTelemetry, Datadog).
- Familiarity with Infrastructure-as-Code tools (e.g., Terraform, Pulumi, Ansible).
- Demonstrated technical leadership across engineering teams, especially in the context of shared platforms or infrastructure.
- Proven experience mentoring engineers within your team and helping foster a culture of technical growth.
- Experience with zero-downtime deployments and blue/green or canary rollouts.
- Prior work with high-throughput, low-latency systems at scale (millions of users or transactions).
- Contributions to open-source infrastructure tools or frameworks.
- Familiarity with compliance frameworks (SOC 2, HIPAA, etc.) in cloud infrastructure.
- Hands-on experience integrating with billing platforms like Zuora, including API usage, data synchronization, and operational monitoring.
