Sr. Software Engineer - Kubernetes

About the Company
Armada is an edge computing startup that provides computing infrastructure to remote areas where connectivity and cloud infrastructure is limited, as well as areas where data needs to be processed locally for real-time analytics and AI at the edge. We're looking to bring on the most brilliant minds to help further our mission of bridging the digital divide with advanced technology infrastructure that can be rapidly deployed  anywhere .

About the role  We are looking for a highly experienced, collaborative, and detail-oriented Senior Engineer to join our growing Edge team. You will be responsible for the design, automation, optimization, and operation of our Kubernetes-based platform supporting our Galleon mobile data centers and Commander cloud integration. This is a critical role where you will leverage deep technical expertise in cloud infrastructure and Kubernetes while valuing mentorship, collaboration, and open communication.

You will work on building and managing resilient, secure, and scalable Kubernetes environments across diverse edge locations and cloud infrastructure, ensuring the reliability of our distributed computing platform.
Location.  This role is office-based at our Trivandrum, Kerala office.
What You'll Do (Key Responsibilities)

Architect, design, deploy, configure, and manage highly available Kubernetes clusters across edge (Galleon data centers) and cloud (AWS, Azure, GCP) environments. This includes designing the cluster layout, resource allocation, and storage configurations
Administer, maintain, and monitor the health, performance, and capacity of Kubernetes clusters and underlying infrastructure
Implement and manage Kubernetes networking solutions (CNI plugins, Ingress controllers) and storage solutions (PV/PVC, Storage Classes, CSI drivers)
Maintain and monitor containerized platform services running within the clusters and robust monitoring, logging, and alerting systems (e.g., Prometheus, Grafana, ELK stack)
Drive Infrastructure-as-Code (IaC) initiatives using tools like Terraform, Ansible, Helm, and potentially Kubernetes Operators, promoting automation, repeatability, and reliability
Support and troubleshoot complex issues related to the Kubernetes platform, containerized services, networking, and infrastructure
Implement and enforce Kubernetes security best practices (RBAC, Network Policies, Secrets Management, Security Contexts, Image Scanning)
Automate cluster operations, deployment pipelines (CI/CD integration), and infrastructure provisioning using Infrastructure as Code (IaC) tools (e.g., Terraform, Ansible)
Optimize Kubernetes clusters for performance, scalability, and resource utilization, particularly in edge environments
Develop and maintain comprehensive documentation for cluster architecture, configurations, operational procedures, and runbooks
Work in collaboration with software engineering, Dev Ops, security teams, and product managers to ensure seamless integration, deployment, and secure operation of applications on Kubernetes
Evaluate and integrate new technologies from the Kubernetes ecosystem
Contribute to the operational excellence of the platform, including participating in on-call rotations, incident management, and building self-healing capabilities

Required Qualifications

Bachelor's degree in computer science, Engineering, Information Technology, a related technical field, or equivalent practical experience
At least 7+ years of professional experience in infrastructure engineering, systems administration, or software development, with a strong focus (4+ years preferred) on building and maintaining production Kubernetes environments
At least 3+ years of professional experience using and administering Linux operating systems
Deep understanding of Kubernetes architecture, core components, operational best practices, and lifecycle management
Strong experience with containerization technologies (Docker)
Hands-on experience managing Kubernetes on at least one major cloud provider (AWS, Azure, GCP)
Strong understanding and proven experience with Infrastructure as Code (IaC) solutions, particularly Terraform and/or Ansible
Proficiency in scripting languages (e.g., Python, Bash) for automation
Experience configuring and managing monitoring/logging tools (e.g., Prometheus, Grafana, ELK Stack)
Solid understanding of Linux operating system, networking fundamentals (TCP/IP, DNS, Load Balancing, Firewalls, VPNs) and container networking (CNI)
Strong understanding of Kubernetes security concepts and implementation (RBAC, Network Policies, Secrets)
Ability to work independently and collaborate effectively with others to debug and solve problems

Preferred Experience and Skills

Experience with Red Hat Open Shift Container Platform (version 4+ is a plus)
Experience deploying and maintaining CI/CD solutions for Dev Sec Ops , such as Git Lab CI or Jenkins
Strong development experience using Docker, docker-compose, and/or Kubernetes
Experience developing Ansible playbooks for process…
