Having a culture built on outcomes and delivery at the core of the business, Capnexus is providing its customers with a complete suite of services for software development, system analysis, integration, implementation, and support, as well as the option to engage a single team to perform all the services they require. Who You Are and What You'll Do: Capnexus is looking for a highly motivated and experienced AWS DevOps Engineer to join our growing team. This is an exciting opportunity for a driven professional passionate about building cutting-edge cloud, automation, and AI-enabled infrastructure solutions in enterprise AWS environments. We are specifically looking for candidates with deep hands-on AWS DevOps experience, ideally including experience working with or alongside AWS Professional Services (AWS ProServe) teams. Responsibilities: • Design and maintain CI/CD pipelines to support automated testing, deployment, and change management across CDP, data lake, marketing cloud, and migration. • Provision and manage AWS environments (S3 buckets, Glue jobs, networking, IAM, VPCs) for non-production development and staging, ensuring environments are logically segregated with no public internet access per SOW requirements. • Implement and enforce infrastructure as code (IaC) using AWS CDK or Terraform to ensure reproducible, auditable environment configurations across all workstreams. • Manage MLOps lifecycle on Amazon SageMaker — including model versioning, deployment automation, endpoint monitoring, and automated retraining triggers for lead scoring, predictive maintenance, underwriting, and audience segmentation models. • Support Amazon Bedrock integration deployments — managing prompt versioning, model configuration, and API endpoint reliability. • Implement and maintain data lake security infrastructure using AWS Lake Formation, including row-level security, column-level encryption, and IAM permission boundaries. • Support Azure to AWS migration execution — provisioning target AWS environments, coordinating AWS DataSync jobs, managing cutover procedures, freeze periods, and rollback plans. • Monitor pipeline health, data job execution, and ML endpoint performance across AWS Glue, Step Functions, Lambda, Kinesis, and SageMaker using CloudWatch and AWS-native observability tools. • Implement cost optimization practices across all AWS services; provide guidance on Azure resource decommissioning post-migration. • Coordinate change management processes per SOW requirements — documenting changes, obtaining approvals, executing peer-reviewed deployments, and maintaining rollback procedures. • Collaborate with Data/ML and Full Stack engineers to ensure smooth integration across data pipelines, ML inference, and application layers. • Contribute to operations runbooks, deployment guides, and infrastructure documentation. Qualifications: • 4+ years of DevOps or cloud infrastructure experience, with at least 2+ years on AWS. • Hands-on experience with CI/CD tooling (GitHub Actions, AWS CodePipeline, Jenkins, or equivalent) in a multi-environment AWS setup. • Proficiency with infrastructure as code — AWS CDK, CloudFormation, or Terraform. • Working knowledge of MLOps practices on Amazon SageMaker — model deployment, endpoint management, monitoring, and pipeline automation. • Experience with AWS IAM, Lake Formation, VPC, and security best practices for data environments. • Familiarity with AWS monitoring and observability tools — CloudWatch, CloudTrail, AWS Config. • Experience supporting data pipeline infrastructure — AWS Glue, Step Functions, Lambda, Kinesis, and S3. • Strong understanding of environment management, change control processes, and rollback procedures in enterprise delivery contexts. • Ability to work in Agile/Scrum teams alongside AWS Professional Services with structured change approval workflows. Nice to Have: • Experience with Azure infrastructure and Azure-to-AWS migration (DataSync, networking, decommissioning). • Familiarity with Amazon Bedrock deployment and API management. • Experience with Amazon Connect or omnichannel platform infrastructure. • Knowledge of data compliance and privacy controls (encryption at rest/in transit, access logging, audit trails). • AWS Certification (DevOps Engineer Professional, Solutions Architect, or Machine Learning Specialty). • Exposure to Kiro CLI or AI-assisted infrastructure tooling. • Background in real estate, property management, or enterprise SaaS environments. “Our Culture”: At Capnexus, the central principles that we all adhere to, and the glue that holds us together, are our keystones.
