About the Position

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
