Senior Software Engineer, Grading OperationsAbout the RoleThe Grading Operations software engineering team builds and operates the internal software that runs our grading and authentication business. That means the applications our operations teams work in every day, the services and APIs behind them, the scheduled and event-driven processes that move items through the grading lifecycle, and the integrations that connect all of it to adjacent systems across the platform.
Volume climbs every year and the systems have kept up. As our grading operations reach more markets, keeping pace means solving for distance as well as volume.
We are looking for a Senior Software Engineer who can help build and evolve the services, event-driven pipelines, and internal applications that keep a high-volume physical operation running. This role is especially well-suited for an engineer who is strongest on the backend, but comfortable working in the frontend to take features all the way to the people who use them.
What You'll Do- Use AI tooling, with a preference for Claude, routinely across software design, architecture, and implementation, while owning the quality of what ships
- Build backend services, APIs, and data models that power the internal applications our grading and authentication teams rely on every day
- Work across a mix of architectures, from a large containerized .NET application to smaller serverless APIs and Python background processing jobs, and help decide which is the right fit for new work
- Design and implement event-driven and asynchronous systems that keep operational data flowing reliably at high volume
- Contribute to frontend application development using JavaScript, TypeScript, and Vue.js to deliver features end to end
- Collaborate with Product, Tech, and Operations teams to translate business requirements into clean technical designs across both backend and frontend systems
- Troubleshoot data, integration, service, and UI issues across a large, long-lived codebase
- Share in an on-call rotation supporting the services the team owns
- Contribute to technical documentation to improve maintainability, knowledge sharing, and team velocity
- Help raise the bar on system design, code quality, observability, and engineering best practices across the team
Who You Are- 5+ years of software engineering experience building production applications, with substantial experience in backend systems and some hands-on experience delivering frontend work
- 3+ years experience / strong proficiency in C# and .NET
- Routine use of AI tooling as part of how you design and build software, with the judgment to review and take responsibility for what it produces
- Experience designing and building RESTful APIs and service integrations
- Sound judgment about where code belongs, including how to draw module boundaries inside a large application and when a capability warrants its own service
- Experience writing and maintaining automated tests for services running in production
- Strong fundamentals working with relational databases and data modeling (e.g. SQL Server, PostgreSQL)
- Hands-on experience building and operating production services in the cloud, including container orchestration (e.g. Docker, Kubernetes, ECS), serverless compute behind an API gateway, and managed messaging and data stores
- Comfortable working in a modern frontend codebase, with hands-on experience in JavaScript, HTML, CSS, and a component-based framework
- Experience with CI/CD pipelines, Infrastructure as Code (e.g. Terraform, CloudFormation), and monitoring and observability tooling (e.g. CloudWatch, Datadog)
- Strong communication and troubleshooting skills, with the ability to document what you build
- Experience turning complex requirements from Product and Operations partners into clean, extensible systems
- Familiar with Agile/Scrum methodologies
Nice to Have- Experience designing asynchronous, event-driven, and distributed systems
- Experience with any of AWS, Python (including test frameworks such as pytest or unittest), Apache Kafka, DynamoDB, or Vue.js
- Experience partnering closely with Product, and comfort working directly with the operations and business teams who use what you build
- Experience making high-volume workflows faster, in the interface or behind it, where shaving seconds off a repeated task adds up across thousands of items
