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.

• 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.

• 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.

• 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.
