Senior AWS DevOps (Part-time)

We are looking for a Senior AWS DevOps Engineer to join our team on a part-time basis. In this role, you will take architectural and execution ownership of a mature cloud ecosystem, focusing entirely on infrastructure modernization, automation, and scaling.

About the project: You will be working on a mobile-first communication and engagement platform designed for large-scale enterprise workforces (enabling secure real-time messaging, broadcasts, and community features). The system architecture is a highly resilient, multi-tenant cloud ecosystem featuring a fast-evolving Generative AI layer (built on advanced RAG models and vector databases). It processes high-volume transactional data, handles massive media asset delivery, and maintains strict industry compliance standards.

Our Tech Stack

• Cloud: AWS (EC2, ECS/Fargate, Lambda for event-driven workloads and AI agent runtime, VPC, Route 53, CloudFront);
• IaC: Terraform, Ansible;
• Data Layer Infrastructure: PostgreSQL (RDS), OpenSearch / OpenSearch Serverless, Amazon S3, RDS Proxy;
• CI/CD & Tools: GitLab, Jenkins.
  
  

Responsibilities

• Architect and implement fully automated, repeatable release pipelines, replacing legacy patterns with modern DevOps best practices;
• Own the deployment and infrastructure orchestration for our Python-based AI agent runtime on AWS Lambda (Graviton/ARM64 architectures);
• Design and lead the infrastructure roadmap for migrating core data storage to a highly scalable serverless architecture to handle peak traffic spikes efficiently;
• Lead the transition of primary transactional databases to high-availability (Multi-AZ) configurations ensuring zero downtime;
• Proactively manage cost optimization, infrastructure right-sizing, security monitoring, and compliance standards.
  
  

Requirements

• Extensive hands-on experience managing core AWS services (including EC2, ECS/Fargate, Lambda, VPC, RDS, and Route 53) within a commercial production environment;
• Solid understanding of hosting, monitoring, and scaling serverless applications and event-driven architectures on AWS Lambda;
• Strong commercial expertise in Terraform for building and maintaining infrastructure as code (experience with Ansible is a plus);
• A solid conceptual understanding of database scaling, multi-tenant pool models with metadata isolation, and serverless compute paradigms;
• Prior experience working within, or maintaining infrastructure for, strict industry compliance frameworks (such as SOC 2 Type II) is highly desirable;
• Ability to write custom Python or Bash scripts for cloud automation, data migrations, and interacting with cloud SDKs.
  
  

Our Benefits

• Flexible part-time hours matching your schedule;
• Professional and career growth promotion;
• Competitive compensation based on tracked hours or fixed retainer;
• Internal Medical Program;
• Program for veterans;
• Regular technical training at our office;
• English courses.
