Back-End Software Engineer

We run a marketplace with over 300,000 active sellers and fulfillment centres in four regions. Since 1992, the company has expanded from listings into payments, shipping and seller financing.

Overview:

This is a new role. The team has doubled in size over the past year. You'll work mostly on server-side code: services, queues, databases and the glue between them. Little to no frontend work. We are headquartered in Hillsboro and have been hiring remotely since 2020. Contract role, full-time hours, paid in USD at the end of each month. Our standups are at 9:00 AM Pacific.

In this role you will:

• Review code for correctness, performance and failure handling
• Handle on-call for services the team owns and lead incident follow-ups
• Coordinate with frontend and mobile engineers on API contracts and versioning
• Secure endpoints with OAuth 2.0, JWT validation and proper input checks
• Add caching with Redis where it actually helps, and remove it where it doesn't
• Implement background jobs and event consumers using Kafka, SQS or RabbitMQ

Minimum qualifications:

• 2+ years of backend development experience in a production environment
• Experience designing and versioning HTTP APIs
• Clear written communication, including design docs
• Working knowledge of message queues or streaming platforms

What you get:

• Monthly internet allowance
• Paid time off
• Annual rate review
• Flexible hours
