• Experience aggregating and visualizing observability data at scale.
• Prior experience operating mission-critical, high-availability systems.
• Strong documentation skills for architecture and design artifacts.

Job Responsibilities:

Design & Architecture

• Design scalable, resilient systems using C4 architecture models (Context, Container, Component, Code) and UML diagrams.
• Define backend, frontend, and data flow architectures with a strong focus on non-functional requirements (availability, latency, scalability, resiliency).
• Drive architectural decisions for SRE, observability, and reliability platforms.

Backend Engineering (Hands-on)

• Develop high-quality, production-grade Java/Python code for:
• Backend services, APIs, synthetic testing frameworks, and reliability tooling
• Observability data ingestion, aggregation, and enrichment pipelines
• Build RESTful and GraphQL APIs using frameworks such as Spring Boot, Django, Flask, FastAPI.
• Implement asynchronous and event-driven systems using Kafka, RabbitMQ, and async frameworks (e.g., asyncio).
• Design and optimize data pipelines that aggregate logs, metrics, traces, and synthetic signals before exposing them to the presentation layer.

UI & Frontend Engineering

• Build and customize rich, data-driven UIs using ReactJS or Angular.
• Develop observability dashboards, synthetic monitoring views, reliability scorecards, and operational insights.
• Integrate frontend applications with backend APIs and streaming data sources.
• Optimize UI performance and usability for large-scale metric visualization and analytics.

SRE, Observability & Reliability Engineering

• Apply Site Reliability Engineering (SRE) principles in system design and development:
• Reliability, Availability, Scalability, and TOIL automation
• Design and implement synthetic tests (availability, latency, user journeys) and expose results through dashboards
• Build solutions around SLIs, SLOs, and Error Budgets, embedding reliability signals directly into platforms.
• Integrate and extend observability tools such as:
• Prometheus, Grafana, Splunk, ELK/OpenSearch
• Aggregate logs, metrics, traces, and synthetic data into a unified observability data model.

Cloud, DevOps & Platform Engineering

• Build and deploy cloud-native applications on AWS, Azure, or GCP.
• Package and deploy services using Docker and Kubernetes / OpenShift.
• Implement CI/CD pipelines using Jenkins, GitHub Actions, GitLab CI.
• Use Infrastructure as Code (IaC) tools such as Terraform, Ansible, CloudFormation.
• Own production readiness, release hygiene, and operational stability.

Quality, Performance & Operations

• Write comprehensive unit, integration, and contract tests.
• Identify performance bottlenecks and optimize backend services, database queries, and UI rendering.
• Monitor production systems, analyze incidents, and drive continuous reliability improvements.

Technical Leadership

• Lead technical and design discussions with senior engineers and architects.
• Review code with a strong focus on clean code, testability, and maintainability.
• Mentor junior engineers and raise the overall engineering bar.
• Evaluate and introduce new technologies that improve reliability, observability, and developer productivity.
