Senior Backend Engineer

What You’ll Do

API & Backend Architecture

• 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.

Platform Reliability & Operations

• 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).

System Contribution & Collaboration

• Contribute production-quality code in Python and/or Node.js across backend services and infrastructure.
• Work closely with the platform engineering manager and cross-functional teams to prioritize backend work that unblocks product delivery.
• Identify and resolve technical debt, performance bottlenecks, and scalability gaps in the backend stack proactively.

What You Bring

Must-Have Qualifications

• Bachelor’s degree in Computer Science or a related field — or equivalent demonstrated experience.
• 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 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.
• Strong Python and/or Node.js skills in a production backend context.
• Experience with CI/CD pipelines, automated testing, and infrastructure-as-code.
• 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

• Familiarity with serverless architecture (AWS Lambda) and event-driven backend design.
• Solid understanding of networking concepts.
• Knowledge of security best practices including IAM, encryption, and OAuth/OpenID implementation.
• Background in 3D imaging, computer vision, or graphics processing pipelines.
• Experience with high-performance computing or low-latency data processing.
• Experience at an AWS consulting partner, service company, or in an AWS-heavy product engineering environment.
