Founded in 2022, we've grown to nearly 200 team members and were named one of LinkedIn's 2025 Top 50 Startups in the United States. We move fast, think big, and love bold ideas that push boundaries (and buttons). From new rewards to fresh game mechanics, every challenge is a chance to innovate and have fun doing it. Our culture is collaborative, curious, and full of laughter because great ideas grow best between coffee, code, and a few epic high‑fives.

• Familiarity with A/B testing, web analytics, and responsive design
• Strong communicator with a proactive, team‑oriented approach
• Experience building or supporting high‑traffic applications or gaming platforms is a plus
• Bachelor's degree in Computer Science or equivalent experience
