About the Role
We are looking for a Senior DevOps Engineer with strong cloud infrastructure expertise (GCP / AWS / Azure) using Terraform and deep MongoDB Atlas ownership experience to design, operate, and scale a cloud-native infrastructure powering a large enterprise SaaS platform.

This is a high-ownership, architecture-level role, not just execution. You will be responsible for designing and running production systems end-to-end, with a particular focus on database infrastructure (MongoDB Atlas) and scalable cloud environments.
You will work in a fully remote, async-first environment, collaborating closely with engineering teams to ensure high availability, performance, and operational excellence across multiple environments.

Responsibilities:
• Design, implement, and operate cloud-native infrastructure across GCP, AWS, or Azure using Terraform.

• Take full ownership of MongoDB Atlas in production, including:

• Cluster architecture and scaling

• Replication and high availability

• Backup and disaster recovery strategies

• Performance tuning and query optimisation

• Security and access control

• Architect and manage containerised and serverless workloads (e.g., Cloud Run, ECS, Kubernetes, or equivalents).

• Design and operate event-driven systems (e.g., Pub/Sub, SQS/SNS, EventBridge, or equivalents).

• Build and maintain CI/CD pipelines with a strong focus on automation, reliability, and scalability.

• Develop reusable Infrastructure as Code (Terraform) modules and manage multi-environment setups.

• Collaborate with engineering teams on system architecture, scalability, and performance optimisation.

• Implement robust monitoring, alerting, and observability across distributed systems.

• Lead incident response and root cause analysis, driving long-term improvements.

• Own infrastructure decisions end-to-end, including architecture, cost optimisation, and performance.

• Document systems, create runbooks, and establish best practices.

• Mentor engineers and promote DevOps best practices across the organisation.

Requirements:
• 6+ years of DevOps / Infrastructure Engineering experience in production environments.

• Strong hands-on experience with at least one major cloud provider: GCP, AWS, or Azure using Terraform.

• Advanced experience with Terraform (modularisation, remote state, multi-environment setups).

• Proven experience designing and operating scalable cloud infrastructure.

• Mandatory: Deep MongoDB Atlas experience in production, including:

• Cluster configuration and scaling

• Replication and failover

• Backup and recovery strategies

• Performance tuning and indexing

• Security and access management

• Experience with containerised environments (Docker, Kubernetes, or equivalents).

• Experience building and maintaining CI/CD pipelines.

• Solid understanding of event-driven architectures.

• Strong knowledge of monitoring, logging, and observability in distributed systems.

• Ability to operate at an architect/owner level, not just execute tasks.

• Strong communication skills and ability to work in a remote, async-first team.

Nice to Have:
• Experience working across multiple cloud providers.

• Experience implementing GitOps practices.

• Familiarity with advanced observability tools (Datadog, APM, tracing).

• Experience supporting high-scale SaaS platforms.

• Interest in platform engineering and developer experience.

Benefits:
• Fixed Shifts: 12:00 PM - 9:30 PM IST (Summer) | 1:00 PM - 10:30 PM IST (Winter)

• No Weekend Work: Real work-life balance

• Day 1 Benefits: Laptop and full medical insurance provided

• Support That Matters: Mentorship, community, and collaboration

• True Belonging: A long-term career where your contributions are valued
