Sr SW Dev Eng- Puppet+Python

Job Summary

Sr Software Engineer - Infrastructure Platform (Python+Puppet) Location - Customer Office, Bangalore.

We are seeking an experienced Platform Engineer to lead the modernization of our core infrastructure services. You will be responsible for redesigning our global Puppet ecosystem-migrating from legacy Puppet 5 to Puppet 7+-while simultaneously scaling and advancing the Puppet infrastructure ecosystem to meet global enterprise needs. You will work across hardware, networking, and platform teams to build scalable, automated, and reliable infrastructure services. This role requires strong Python development skills to build robust, API-driven tools that orchestrate our infrastructure workflows.

Responsibilities

• Redesign Consolidate: Lead the architectural redesign of the Puppet ecosystem, migrating legacy Puppet 5 systems to Puppet 7+.
• Technology Consolidation: Consolidate multiple configuration management technologies (Ansible, Puppet) into a unified, enterprise-standard, and at-scale solution.
• IaC Implementation: Maintain reusable playbooks/modules and templates to enforce configuration standards, security baselines, and repeatable deployments across environments.
• PuppetDB Hiera Optimization: Architect and manage PuppetDB for high availability and performance. Optimize complex Hiera hierarchies and data lookups to ensure efficient configuration management at scale.
• Development Workflows: Improve Puppet code development lifecycles by implementing robust testing frameworks (e.g., RSpec, Beaker) and streamlining CI/CD pipelines for configuration changes.
• Global Scalability: Design and maintain a geographically distributed Puppet architecture that supports thousands of nodes across global datacenters with minimal latency and high reliability.
• Python Automation Platform Integration API-First Development: Develop enterprise-grade Python tools and APIs to orchestrate infrastructure workflows (compute, storage, network, cloud).
• Self-Service Workflows: Build automation to support self-service workflows, reducing manual operational tasks and improving deployment script efficiency.
• Orchestration: Integrate internal/external APIs to facilitate automated service provisioning and resource management.
• Observability Reliability Monitoring: Implement and improve monitoring, alerting, and dashboards for infrastructure health (e.g., Prometheus, Grafana, ELK/Nagios).
• Incident Response: Participate in incident response, perform root cause analysis, and implement long-term fixes/runbooks. Define and track key metrics (availability, latency, capacity) to drive data-based improvements.

Requirements

• Python Programming: 5+ years of enterprise software development experience, focusing on automation scripts, internal tooling, and REST API integrations.
• Puppet Expertise: Deep, hands-on knowledge of Puppet 5/7 ecosystems, including both user and development experience.
• Advanced Puppet Mastery: Expert-level experience in Puppet architecture, including advanced Hiera data modeling and complex custom module development.
• Configuration Management: Strong experience with IaC tools such as Ansible, Terraform, or Puppet.
• Infrastructure: Proficiency with Linux systems administration, bare-metal provisioning, and hypervisor deployment. Familiarity with CMDB systems as a source of truth.
• Collaboration Mindset: Strong operational mindset with a focus on reliability, correctness, and supportability. Experience working cross-functionally with hardware, software, storage, and SRE teams. Ability to drive ambiguous technical problems to clear, automated, and scalable solutions.

Plus Points / Preferred Qualifications

• CI/CD Pipeline Experience: Exposure to tooling such as Jenkins, GitHub Actions, ArgoCD, or GitLab CI.
• SRE/DevOps: Background in SRE methodologies, observability, and incident management (e.g., Incident Commander systems).
• Cloud Kubernetes: Experience with large-scale internal platforms, Kubernetes deployment, and hybrid/multi-datacenter environments.
• Infrastructure as Product: Experience operating self-service platforms and developer enablement
