Software Engineer (Entry Level)

Double Holo is building the market intelligence platform for trading cards. They are seeking an early-career engineer who wants to grow fast by shipping real software to real users and will work across the full stack on various impactful features.

Responsibilities:

• Marketplace features across web and mobile: listings, live order books, checkout, seller tools
• API endpoints and background jobs that power pricing analytics, portfolio tracking, and market alerts
• Data pipelines that keep prices, sales history, and population data fresh across millions of records
• Production debugging: taking an error report from stack trace to root cause to shipped fix
• Internal tools that our team and vendors rely on every day
• Performance work: making dense data views feel fast on web and mobile

Requirements:

• Have a bachelor's degree in computer science or a related field
• Have built and finished real things: internships, substantial class projects, personal apps, open source
• Are solid in at least one of JavaScript/TypeScript or Ruby, and eager to work in both
• Communicate early and clearly, especially when you're stuck
• Take feedback well and iterate fast: our community reacts to what we ship within hours
• Want ownership and accountability earlier than a big company would ever give you
• Bonus points if you've worked with React, React Native, Rails, SQL, payments, or anything camera/computer vision
• Collecting trading cards is a plus - but definitely not required
