Job description

At Playlist, life’s richest moments happen when people step away from screens to move, connect, explore, and play. We’re building the definitive platform for intentional living, connecting people with inspiring experiences in fitness, wellness, and beyond. With popular brands like Mindbody and ClassPass, Playlist empowers businesses and individuals, making it effortless for aspirations to become actions. Join us in reshaping technology’s role to foster meaningful, real-world connections.

Mindbody equips wellness entrepreneurs with technology to support thriving businesses and create exceptional experiences. Innovation and curiosity drive our culture, connecting businesses and individuals through cutting‑edge solutions. Join us if you’re passionate about enhancing wellness through technology.

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

Technologies You Could Be Working With

• Languages: C# and .NET / ASP.NET, React/Next.js/TypeScript
• Data: PostgreSQL / Amazon Aurora (Npgsql), Microsoft SQL Server, DynamoDB, EDW (Snowflake), Redis (AWS ElastiCache), FluentMigrator
• Architecture: Microservices on AWS including event driven (SNS, SQS, Lambda, EKS, Aurora, ElastiCache, CloudWatch, Secrets Manager, STS), with CDC pipelines and GraphQL
• Monitoring: New Relic, NLog, CloudWatch Logs
• This list is here to show how we work today. We do not expect you to have used every technology on it.
