Junior Application Developer Jobs in Spring Hill, FL

About the Role: AFS is searching for Principal Kubernetes Solutions Architect to drive the design, deployment, and automation of Kubernetes-based platforms. This leadership role focuses on architecting secure, scalable, and highly available container orchestration environments to support business-critical workloads. The ideal candidate excels at building robust Kubernetes clusters and enabling development teams to maximize platform capabilities.  

As a recognized expert in Kubernetes, you will leverage your deep experience in cluster management, security, and scaling to deliver resilient containerized solutions. Your advanced skills in Infrastructure as Code, CI/CD pipelines, and cloud-native automation will empower development teams to efficiently utilize self-service Kubernetes platforms.  

While the primary focus is Kubernetes, expertise with hybrid and private cloud environments such as VMware vSphere or OpenShift further distinguishes candidates.  

Responsibilities:  

• Architect, build, and maintain Kubernetes clusters with an emphasis on scalability, reliability, and security, utilizing best practices for cluster lifecycle management.  

• Manage core Kubernetes services, including networking, storage, workload scheduling, and RBAC for access control.  

• Oversee containerized workloads, ensuring high availability, efficient scaling, and robust security for multi-tenant environments.  

• Architect, build, and maintain Kubernetes clusters with a strong focus on scalability, reliability, and security, applying best practices for cluster lifecycle management while overseeing core Kubernetes services including networking, storage, workload scheduling, and RBAC for access control.  

• Design, implement, and manage Kubernetes Operators to automate operational tasks and lifecycle management of complex applications. Leverage both custom-built and existing Operators to streamline deployment, monitoring, and maintenance of workloads, ensuring consistency and reliability across environments. 

• Drive Infrastructure as Code (IaC) initiatives using tools like Terraform to automate Kubernetes resource provisioning.  

• Design, implement, and optimize CI/CD pipelines for containerized applications, embedding security controls throughout the pipeline.  

• Build custom automation tools and scripts (Python, Go, Bash) to enhance Kubernetes operations and minimize manual tasks, leveraging APIs for integration.  

• Serve as the Kubernetes subject-matter expert, mentoring development teams and guiding optimal use of container orchestration technologies.  

• Collaborate with stakeholders to assess new Kubernetes-native solutions and recommend enhancements to platform efficiency and capabilities.  

• Promote best practices in Git workflows and the use of AI tools to accelerate the development and troubleshooting of container-based applications.  

• Break down large projects into actionable tasks for junior team members.  

Required Skills & Experience:  

• 10 years of relevant experience in any of the following:

• Advanced proficiency with Infrastructure as Code (IaC), especially Terraform, including, but not limited to targeted applies, imports, and complex module usage.  
• Significant experience architecting, deploying, and managing Kubernetes clusters (Amazon EKS or equivalent).  
• Strong command of Kubernetes RBAC, security policies, and best practices.  
• Demonstrated experience designing, building, and maintaining automated CI/CD pipelines for containerized workloads.  
• Thorough understanding of Kubernetes networking, Linux/Unix systems, and platform security.  
• Proficiency with Git and GitOps workflows for Kubernetes resource management.  

• Must hold and maintain DoD 8140 certifications.  

Preferred Qualifications:  

• Experience with VMware vSphere or OpenShift in hybrid or private cloud contexts.  

• Proven experience building custom Kubernetes operators. 

• Familiarity with configuration management tools (e.g., Ansible).  

• Exposure to public cloud platforms (AWS, Azure, GCP) and DevOps methodologies.  

• Advanced programming skills in Python, Go, or JavaScript/TypeScript.  

• Understanding of authentication protocols including OIDC, OAuth2, LDAP, and SAML.  

• Contributions to open-source Kubernetes or DevOps projects.  

Relevant certifications: 

• Kubernetes certifications such as Certified Kubernetes Administrator (CKA), Certified Kubernetes Application Developer (CKAD), Certified Kubernetes Security Specialist (CKS), and Kubestronaut.
