Staff Software Engineer, Full-Stack

What You’ll Do:

Design and build scalable cloud-based systems on AWS that power core collectibles platforms and experiences

Develop APIs and backend services that enable seamless web and mobile customer journeys across buying, selling, authentication, and grading

Own technical architecture and delivery of end-to-end features, from design through deployment, with staff-level influence across teams

Work on highly intricate grading and authentication workflows that ensure trust, accuracy, and consistency at scale

Improve and evolve existing systems, identifying opportunities to enhance performance, scalability, and reliability

Leverage modern AI tools and techniques to accelerate development, improve engineering velocity, and explore new ways of building

Provide technical leadership through design reviews, code reviews, and mentorship, raising engineering quality across teams

Who You Are:

7+ years of software engineering experience building web applications, APIs, and distributed systems at scale

Experience at product-driven, tech-forward companies building service-oriented or microservice-based systems

3+ years of hands-on AWS experience, including serverless and event-driven architectures

Use modern AI tools (e.g. Claude Cowork, Codex) as a crucial part of your development workflow to accelerate delivery, improve engineering velocity, and explore new approaches to building that drive team-wide productivity and innovation

Strong fundamentals in engineering (OOP, design patterns, testing, security, observability), with deep proficiency in at least one object-oriented language and ability and willingness to work across languages such as Python, C#, or Java

Familiarity with modern client-side frameworks (e.g., React, Next.js) and delivering consumer-facing digital experiences
