DevSecOps Engineer

DevSecOps Engineer / AWS Cloud Engineer (Serverless, CI/CD, IaC, ECS Fargate) Location: Remote Role Summary We are seeking a highly skilled AWS Cloud / DevSecOps Engineer to design, build, and maintain secure, scalable, highly automated cloud-native environments on AWS. This role will lead the engineering of production-grade serverless APIs , event-driven workflows , and containerized services , while embedding security and operational excellence into every stage of the delivery lifecycle (infrastructure, pipelines, runtime, and monitoring). You will partner closely with application engineers (frontend and backend), architects, and security stakeholders to deliver mission-critical systems with strong reliability, performance, and governance. Key Responsibilities Cloud architecture & delivery Design and implement cloud-native architectures on AWS, emphasizing serverless-first patterns where appropriate. Build and maintain production-ready serverless APIs using AWS Lambda, API Gateway , and related integration patterns (authorizers, throttling, request validation, WAF integration as needed). Create event-driven workflows and orchestration using AWS Step Functions , including retries, error handling, idempotency, and observability. Design and maintain containerized workloads using Docker and Amazon ECS on Fargate , including task definitions, scaling, service discovery, and secure networking. Infrastructure as Code (IaC) & environment management Develop and manage infrastructure using AWS CloudFormation (and/or complementary IaC practices as applicable), ensuring reusability, composability, and environment parity (dev/test/prod). Implement guardrails for consistent provisioning: tagging standards, baseline security controls, secrets handling, and standardized logging/monitoring. Manage VPC, subnets, routing, security groups, NACLs , endpoints, and connectivity patterns for secure, least-privilege architectures. CI/CD & automation (DevSecOps) Build and maintain GitLab CI/CD pipelines for automated testing, security checks, deployments, and rollbacks across multiple environments. Automate release workflows for serverless and container platforms (blue/green or canary strategies where applicable). Implement pipeline-integrated security controls (e.g., dependency scanning, container scanning, IaC scanning, policy-as-code where applicable) and ensure audit-ready traceability. Security engineering (built-in, not bolted-on) Architect secure AWS environments leveraging IAM (least privilege, role-based access, permission boundaries where useful), encryption (KMS), and secure secrets management. Implement logging and detection best practices using services such as CloudWatch Logs/Metrics/Alarms , CloudTrail , and centralized log aggregation patterns. Ensure secure configuration and operational readiness: patching/immutability strategies, secure image practices, runtime hardening, and incident response readiness. Data & persistence Design and maintain MySQL / Amazon RDS environments, including backups, parameter tuning, maintenance windows, read replicas (if needed), and secure connectivity. Support application teams with data-access patterns, migrations, and reliability considerations (connection management for serverless, pooling/proxy patterns where applicable). Required Qualifications Hands-on expertise building serverless solutions with AWS Lambda , API Gateway , and Step Functions in production. Strong experience with AWS CloudFormation for provisioning and managing environments. Strong CI/CD experience, specifically building and operating GitLab CI/CD pipelines . Strong container expertise with Docker and running workloads on ECS Fargate (services, tasks, scaling, networking). Demonstrated experience architecting secure AWS environments using IAM , VPC/networking , encryption , and logging/auditing best practices. Experience designing/operating MySQL / Amazon RDS in production. Strong scripting/automation skills (e.g., Python and/or Bash) to streamline workflows and reduce toil. Ability to collaborate effectively with frontend/backend engineering teams and translate requirements into secure, automated platform capabilities. Security+ or higher certification AWS Cloud Practitioner certification or higher TS security clearance or the ability to obtain one Preferred Qualifications (Nice to Have) Familiarity with AWS CDK or Terraform (even if CloudFormation remains primary). Experience with API security patterns: OAuth/OIDC integration, JWT authorizers, rate limiting/throttling, WAF, mTLS (where required). Experience with secrets management (e.g., AWS Secrets Manager / SSM Parameter Store ) and key management ( KMS ). Observability stack experience beyond basics: structured logging, tracing (e.g., X-Ray/OpenTelemetry patterns), metrics-driven alerting. Experience implementing policy-as-code and governance (e.g., SCPs/Organizations, config rules, control frameworks). Experience with performance/cost optimization for ser
