About the role

  • You will take full ownership of the API layer, cloud architecture, and backend services that move complex 3D scene data from mobile capture through processing and delivery via Quidient Reality®.
  • This is a hybrid position, meaning that you will need to live within easy driving distance to our Technology Center in Columbia, Maryland.

Responsibilities

  • Own and evolve the backend API layer that enables commercial partners and internal applications to integrate with Quidient's 3D reconstruction and processing platform.
  • Design and maintain microservice architectures that handle the flow of 3D scene data from mobile capture through cloud-based processing and delivery.
  • Build and operate cloud infrastructure on AWS - including compute, storage, networking, and serverless components - with a focus on reliability, security, and cost efficiency.
  • Implement and maintain CI/CD pipelines, containerized deployments (Docker), and infrastructure-as-code to streamline the software delivery process.
  • Monitor system performance, troubleshoot backend and cloud issues, and maintain platform uptime for production workloads.
  • Design and implement systems for computational offloading - moving high-performance, low-latency processing from edge devices to cloud infrastructure.
  • Implement security best practices including IAM policies, encryption at rest and in transit, and authentication protocols (OAuth/OpenID).

Requirements

  • Bachelor's degree in Computer Science or a related field - or equivalent demonstrated experience.
  • Strong experience with AWS at the application layer - Lambda, API Gateway, S3, EC2, ECS/EKS, CloudFormation, or equivalent services.
  • Hands-on experience with Docker, containerized deployments, and microservice architecture.
  • Experience with CI/CD pipelines, automated testing, and infrastructure-as-code.
  • Must-Have Qualifications:
  • 4+ years of professional experience building and maintaining backend systems and APIs in production environments.
  • Solid backend architecture skills - you can design APIs, data models, and service boundaries that hold up under real production load.
  • Strong Python and/or Node.js skills in a production backend context.
  • This position is not eligible for H-1B sponsorship.
  • Willingness to work on-site in Columbia, MD, in a hybrid capacity.
  • Meet Quidient, customer, and government security requirements, which may include, but are not limited to a background check, citizenship verification, and Criminal Justice Information Services verification.
  • Nice-to-Have Qualifications:
