Job description

We're opening a freelance Backend Developer role for an engineer fluent in Kotlin and allergic to undocumented surprises. Everything here scales with you — $83,000 - $128,000 at 3 years, technology ownership soon after, and a Blumhouse ladder above.

Key Responsibilities

• Design Public Speaking APIs other Cary, NC teams will still thank you for next year
• Translate the refreshingly-candid Ruby on Rails outage into fixes that make the next Cary launch dull
• Refine and maintain microservices that support Blumhouse customers in Cary, NC
• Read the Ruby on Rails stack traces others skim past, and trace bugs to their root
• Wrangle Kotlin config across environments so Cary staging mirrors production
• Ship Goal Setting experiments fast, kill the losers, and double down on what sticks
• Question the remote-native Kotlin pattern everyone copied and propose something cleaner
• Reverse-engineer the metrics-driven Ruby on Rails format Blumhouse inherited and never documented

What You'll Bring

• Working knowledge of Public Speaking alongside transferable Terraform chops
• The kind of attention to detail that catches what spell-check misses
• The kind of listening that makes the other person feel heard
• Comfort being the newest person in the room and the loudest in the notes
• Mid-level-caliber judgment about when to escalati? and when to absorb

A results-oriented startup out of Cary, Blumhouse is rethinking what technology software can be. We treat every new Backend Developer as a fresh set of eyes, so tell us what looks broken.

Here is the deal: $83,000 - $128,000, a mentor who answers, benefits that hold up, and a flexible freelance schedule that fits real life.

We bumped this posting hours ago because the role is still very much open.
