The Role You'll Play

Playlist builds software for the wellness and services economy. Our platforms include Mindbody for fitness and wellness studios, Booker for appointment-based businesses, and Kite for large multi-location franchises, with more verticals on the way. Tens of thousands of businesses run their day-to-day operations on our products.

As a Software Engineer III on this team, you’ll help build the outbound marketing side of Playlist's CRM and Marketing platform — the tools our customers use to stay in touch with their clients and bring them back. That includes:

• Marketing campaigns

• Automated lifecycle journeys

• Re-engagement and retention automation

• Audience and subscriber management

Right now, much of this runs on a third-party marketing platform. We’re building those capabilities in-house, starting with a customer segmentation engine that lets businesses define and target audiences from their own data. There’s a lot to build, and we’re hiring engineers to make it happen.

What You'll Do

• Build and ship production code for services behind campaigns, journeys, and audience management

• Develop and test APIs, ensuring customer and subscriber records stay in sync through robust data pipelines

• Add features to segmentation and targeting tools, while fixing bugs and reviewing pull requests

• Collaborate closely with Product, Design, and senior engineers to shape solutions from well-defined tickets to larger system components

• Handle production issues with the team, contributing to reliability and resilience

• Grow into ownership of larger pieces of the system as you gain familiarity

Experience You Bring

• Strong coding mindset: you care about writing great code and solving the right problems

• Proficiency with languages like C#/.NET and TypeScript/JavaScript

• API design expertise and experience with microservice architecture

• Observability familiarity with tools like New Relic or Kibana

• Deep SQL knowledge and relational data modeling skills

• Agile mindset with strong grasp of software development lifecycle practices

• Ability to navigate complexity, assess tradeoffs, and execute with confidence

• Excellent communicator who brings others along and helps ideas stick
