Middle DevOps Engineer

AppRecode is looking for a Middle DevOps Engineer to lead infrastructure modernization for a client transitioning from a hybrid setup to a fully cloud-native architecture.

This is a hands-on role with strategic impact — you'll be analyzing existing infrastructure, designing AWS migration paths, and building developer-enabling solutions from the ground up. The client operates a Node.js + Vue.js application with multi-tenant deployments on Kubernetes, and needs an experienced engineer to simplify complexity, complete the AWS transition, and establish self-service deployment workflows for their development teams.

Project Overview

Our client operates a hybrid infrastructure application (Node.js + Vue.js) split between AWS and on-premises environments. The current setup includes multiple development instances and separate deployments for each client (20+ instances) running on Kubernetes, with CI/CD pipelines in GitLab. We're looking for a Middle DevOps Engineer to lead the infrastructure modernization effort: analyzing the existing setup, designing a simplified cloud-native architecture, completing the AWS migration, and enabling developer self-service deployments.

Responsibilities

• Analyze current hybrid infrastructure (AWS + on-premises) and document the existing architecture, deployment patterns, and pain points
• Design and implement complete AWS migration strategy for all workloads currently running on-premises
• Build production-grade AWS infrastructure from scratch using Infrastructure as Code (Terraform)
• Optimize Kubernetes architecture to support multi-tenant deployments efficiently
• Implement ephemeral environments for PR testing to enable developers to validate changes before merging
• Redesign and optimize GitLab CI/CD pipelines for developer self-service deployments
• Create comprehensive documentation for development teams covering infrastructure components, deployment workflows, and critical integration points (including AI-powered features)
• Work with existing development team (including handover from previous infrastructure owner) to ensure smooth knowledge transfer
• Establish monitoring, logging, and alerting infrastructure for production and development environments

Nice to Have

• Experience with multi-tenant Kubernetes architectures
• Knowledge of cost optimization techniques for AWS workloads
• Familiarity with GitOps practices and tools (ArgoCD, Flux)
• Experience with Node.js and Vue.js application deployment patterns
• Background in migrating legacy systems to cloud-native architectures
• Experience creating developer-focused documentation and runbooks
• Experience with observability tools (Prometheus, Grafana, ELK stack)
• German language skills (for direct communication with existing dev team)

Candidate Profile

• 3-4 years of hands-on AWS experience (EC2, ECS/EKS, RDS, VPC, IAM, CloudWatch)
• 2-3 years of Kubernetes experience in production environments
• Proven track record of AWS migrations and building infrastructure from scratch
• Strong Infrastructure as Code skills (Terraform preferred)
• Experience with GitLab CI/CD or similar platforms
• Excellent documentation and communication skills
• Ability to work independently and drive technical decisions
• English: Upper-Intermediate or higher (for communication with German development team)
• Availability: 3+ months with high possibility of extension

What AppRecode offers

• 20 days of paid annual leave plus public holidays.
• 5 paid sick days per year.
• Remote-first work environment.
• Friendly and supportive team culture.
• Personal development plans and access to experienced mentors and technical leaders.
• Reimbursement for sports activities and professional certifications (after probation).
• Ongoing learning opportunities: internal trainings and knowledge-sharing sessions.
• Free English classes if you want to further improve your communication skills.
