Senior Software Engineer - Grading Operations

Collectors • Santa Ana, CA

3d • Remote

About The Position

The Grading Operations software engineering team builds and operates the internal software that runs our grading and authentication business. This includes the applications our operations teams use daily, the supporting services and APIs, scheduled and event-driven processes for the grading lifecycle, and integrations with other platform systems. As grading operations expand globally, the team needs to address challenges of both volume and distance. The role is ideal for a backend-focused engineer who is also comfortable with frontend development to deliver complete features.

Collectors is a leading creator of technology for collectors worldwide, grading, authenticating, vaulting, and selling collectibles. With subsidiaries like PSA, PCGS, and Beckett, the company has graded millions of items since 1986 and employs over 3000 people globally.

Requirements

• 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 Haves

• 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

Responsibilities

• 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

Benefits

• Equal employment opportunity regardless of race, color, ethnicity, ancestry, religion, national origin, gender, sex, gender identity or expression, sexual orientation, age, citizenship, marital or parental status, disability, veteran status, or other class protected by applicable law.
