Job Description

Remote | Active SECRET Clearance Required | U.S. Citizenship Required

A role for engineers who like building real systems.

Most job postings say “full stack” but end up meaning mostly frontend or mostly backend. This role is actually full stack.

You will design, build, deploy, and operate production software that integrates geospatial data, external APIs, and cloud infrastructure. These systems support mission‑driven environments where reliability, performance, and security matter.

Because of the work we support, an active SECRET clearance is required. If you already operate in cleared environments, you know what that means. Disciplined engineering, thoughtful architecture, and systems that need to work when people rely on them.

Tech Stack

Core Development

• C# / ASP.NET
• Node.js
• REST and GraphQL APIs

Data

• SQL Server
• MySQL
• Azure Cosmos DB

Cloud and DevOps

• Microsoft Azure
• Azure DevOps CI/CD
• Azure Key Vault
• Azure Cache for Redis

Geospatial

• ArcGIS
• Leaflet

The Kind Of Developer Who Will Enjoy This Role

Like owning features from idea through deployment, moving comfortably between backend services, databases, and infrastructure, preferring building working software over sitting in meetings, caring about how systems actually run in production, and comfortable jumping across the stack. Debugging a Node service, improving a query, or helping refine a deployment pipeline are all part of the job.

What You Will Work On

Full Stack Development

• Build and maintain applications using C# / ASP.NET and Node.js
• Integrate mapping technologies such as ArcGIS and Leaflet
• Build and consume REST and GraphQL APIs

Data Systems

• Design schemas and write queries across SQL Server, MySQL, and Cosmos DB
• Improve performance through query tuning and indexing

Cloud and DevOps

• Work with Azure DevOps pipelines and CI/CD workflows
• Deploy and operate services in Azure environments
• Manage secrets and infrastructure components such as Key Vault and Redis

Production Operations

• Support incident response and root cause analysis
• Improve monitoring, logging, and system reliability

Qualifications

What you need to qualify:

• At a minimum an ACTIVE SECRET CLEARANCE
• 5 plus years of experience as a Software Engineer developing applications with C# and ASP.NET
• Experience developing services or applications using Node.js
• Experience working with relational and NoSQL databases including SQL Server, MySQL, and MongoDB or Azure Cosmos DB
• Experience integrating systems through REST or GraphQL APIs

Bonus points if you have the following

• Hands on experience implementing GIS or mapping technologies such as ArcGIS or Leaflet
• Experience with Azure DevOps and CI/CD pipelines
• Experience with Azure Key Vault and Redis
• Database administration experience in production environments
• Experience working in DoD or other regulated environments
• Azure certifications such as AZ 204 or AZ 400
• Experience with Docker, AKS, or Azure Container Apps
• Infrastructure as Code such as Terraform, ARM, or Bicep
