They are seeking a Senior Software Engineer to build the PSA Liquidity Platform, which connects supply and demand across their marketplace, enhancing buyer and seller experiences.
Responsibilities
- Lead development of our next-generation buyer platform: targeting, campaign management, budget controls, and analytics that let every type of buyer — from individual collectors to large-scale dealers — discover and acquire the right cards at scale
- Partner with Engineering and AI/ML to build a sophisticated, real-time targeting and ranking engine that maximizes GMV, conversion, and offer-to-sale velocity across channels
- Design and operate microservices and distributed, event-driven systems that power instant, accurate offers across millions of collectibles — with the low latency and reliability our customers expect
- Make it effortless for sellers to understand their options, price their items accurately, and complete a sale with minimal friction
- Use AI tooling across the development lifecycle to move faster and raise quality, and bring a strong point of view on how AI changes the way we design, build, and operate software
- Take projects from 0 to 1 — from an ambiguous problem to a shipped, instrumented, production product — and wear whatever hat the moment requires, whether that's frontend, backend, infrastructure, or data
- Translate strategy into clear technical plans, specs, and user stories. Coordinate delivery across dedicated and partner engineering teams, and keep stakeholders aligned and projects moving
- Ensure seamless liquidity handoffs across the broader PSA enterprise, from Grading to Collection Management to Vaulting, reducing friction and resolving cross-system dependencies that span payments, logistics, and risk
- From executive reviews to engineering standups, synthesize complexity, articulate tradeoffs, and bring people with you — clearly, in writing and in person
