Backend Engineer, Marketplace

What You’ll Build

• Backend services that power candidate-job matching, routing, and marketplace workflows
• APIs and internal systems for search, eligibility, scoring, allocation, and fulfillment
• Data models and system abstractions for a rapidly evolving labor marketplace
• Infrastructure for real-time and asynchronous decisioning at high volume
• Operational systems and tooling that keep product-critical workflows reliable, observable, and easy to evolve

Example Problems

• Build the systems that determine which candidates are eligible for which opportunities
• Design matching and allocation infrastructure that balances speed, quality, and fill rate
• Improve the performance and reliability of APIs serving marketplace decisions in real time
• Develop workflow engines for onboarding, vetting, routing, and placement
• Design backend abstractions that let product and ML teams iterate quickly without degrading system quality

What We’re Looking For

• Track record of building and operating reliable backend systems in production
• Strong judgment in system design, performance, reliability, and data modeling
• Comfort working on high-throughput APIs, distributed systems, and asynchronous workflows
• Ability to translate product and marketplace requirements into clean technical systems
• High engineering standards and a bias toward simple, durable abstractions

Nice to Have

• Experience with search, recommendation, matching, scheduling, or marketplace systems
• Experience supporting ML-powered products or integrating model inference into production systems
• Familiarity with event-driven architecture, queues, caching, and observability tooling
