About

We’re looking for an Interactive Sound Designer who thrives on creating fun, rewarding, and memorable audio experiences. You’ll be designing exciting popping sound effects for our gamified app’s flows, features, and actions, similar to Duolingo’s correct-answer cues, post-lesson summaries, and our own game-like rank-ups. This is a contract role to deliver a set of sound effects; the exact scope and pricing will be discussed and agreed upon together. What You’ll Do Create a set of polished, engaging sound effects and short jingles that enhance key in-app moments (e.g., rank-ups, feature unlocks, button taps, streak completions). Deliver finalized files in standard audio formats (.wav and/or .mp3) optimized for mobile use. Work with our design team to align sound effects with the app’s playful, gamified aesthetic. About Us At Liftoff, we're reimagining the way people stick to fitness. Our mobile app turns working out into a gamified experience, ranking lifts like a video game and visualizing progress through interactive features such as levels, streaks, quests, and an in-app shop. We've grown to over 1 million users worldwide with a 4.9 App Store rating, fueled by metrics and community feedback. We move fast, learn even faster, and double down on what works. If shaping the future of fitness excites you, you'll love working with us.
