Description & Requirements
Elder Research Inc., a wholly owned subsidiary of MANTECH international Corporation seeks a motivated, career and customer-oriented Junior Cloud Developer to join our team in Arlington, VA. This position is hybrid with 1-4+ days a month on site.
We are seeking a motivated Junior Cloud Developer to join our cloud infrastructure team. In this role, you will design, deploy, and maintain scalable cloud solutions on AWS, with a strong focus on Infrastructure as Code using AWS CloudFormation. You will work alongside senior engineers to build containerized workloads on ECS Fargate, package Python applications as production-grade Docker images, and contribute to a culture of operational excellence through observability, automation, and secure-by-default practices.
Responsibilities Include But Are Not Limited To

• CloudFormation & Infrastructure as Code (Primary)

• Author, review, and maintain CloudFormation stacks for ECS clusters, services, task definitions, ALBs, Target Groups, IAM roles/policies, and ECR repositories, while parameterizing stacks for portability across dev, staging, and production and ensuring compliance with organizational standards, security baselines, and ACES/CCoE governance patterns.
• Implement drift detection, manage stack updates, and utilize StackSets where appropriate; participate in stack reviews to ensure consistency, security, and reusability of infrastructure templates.

• ECS Fargate

• Design and deploy Fargate services using awsvpc networking, task roles, and service-level autoscaling, including configuration of ALB routing, target groups, health checks, and deployment strategies such as blue/green and canary releases.
• Define and maintain service-level observability using CloudWatch Logs, CloudWatch Metrics and Alarms, and AWS X-Ray tracing.

• Docker & Python

• Convert Python projects into production-grade Docker images using multi-stage builds, slim base images, and reproducible build patterns, and publish/manage images in Amazon ECR following tagging and lifecycle policy standards.
• Configure runtime settings and secrets via AWS Parameter Store and Secrets Manager, enforcing least-privilege access through task role–scoped IAM policies

• Lambda (Secondary)

• Build and maintain CloudFormation-deployed Lambda functions for lightweight control-plane tasks (e.g., policy orchestration, scheduled maintenance operations) while ensuring compliance with organizational controls and tagging policies per established operating procedures.

Minimum Qualifications

• Bachelor's degree in Computer Science, Information Systems, or related field — or equivalent practical experience.
• 1–2 years of experience with AWS services, including hands-on use of CloudFormation, ECS, ECR, IAM, and VPC networking.
• Must be a US Citizen and be able to obtain and maintain a Public Trust clearance prior to starting this position.
• Working knowledge of Docker: writing Dockerfiles, building images, and managing container lifecycles.
• Proficiency in Python; experience packaging Python applications for containerized deployments preferred.
• Familiarity with ALB configuration, target groups, listener rules, and health check behavior.
• Understanding of IAM fundamentals: roles, policies, trust relationships, and least-privilege principles.
• Basic familiarity with AWS CloudWatch for logging and monitoring.

Preferred Qualifications

• Exposure to ECS Fargate task definitions, awsvpc networking mode, and service autoscaling configurations.
• Experience with blue/green or canary deployment strategies via AWS CodeDeploy or similar.
• Familiarity with AWS Parameter Store and/or Secrets Manager for runtime secret injection.
• AWS Certified Cloud Practitioner or AWS Certified Developer – Associate certification (or in progress).
• Familiarity with Lambda development and event-driven architectures.
• Typescript

Clearance Requirements

• Must be a US Citizen and be able to obtain and maintain a Public Trust clearance prior to starting this position.
