  • Automate infrastructure provisioning and deployment using tools such as CloudFormation, Terraform, and PowerShell.
  • Ensure compliance with FedRAMP, FISMA, and other regulatory requirements for AWS GovCloud environments.
  • Monitor, troubleshoot, and optimize migrated workloads for performance, cost, and reliability.
  • Document migration processes, configurations, and operational procedures for knowledge transfer and support.

  • Deep knowledge of AWS GovCloud and its security/compliance requirements.
  • Strong experience with AWS services, including EC2, S3, RDS, VPC, IAM, CloudFormation/Terraform, and CloudWatch.
  • Background in system integration, application dependency mapping, and performance optimization.
  • Proficiency with automation tools and scripting (PowerShell, Python, Bash).
  • Solid understanding of networking concepts (DNS, VPNs, firewalls, load balancing) and hybrid cloud connectivity.
  • Strong knowledge of security best practices, including IAM, encryption, and compliance frameworks (FedRAMP, FISMA).
  • Excellent communication and collaboration skills, with the ability to lead cross-functional teams.

For government reporting purposes, we ask candidates to respond to the below self-identification survey. Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file.

As set forth in Dev Technology’s Equal Employment Opportunity policy, we do not discriminate on the basis of any protected group status under any applicable law.

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
