Sr Software Engineer
Confirmed on the employer's own hiring board on Nov 10, 2026. First seen by Alion on Nov 10, 2026. Playlist scores B on the Alion truth index.
About the Company:
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.
Playlist is building the infrastructure behind the experience economy. It's the company behind ClassPass, Mindbody, Booker, EGYM and Kite. Booker is our booking and business software for spas, salons and wellness businesses. Booker has been in maintenance mode for a few years, but it is now the product Playlist sells by default for spa businesses, and the company is putting more investment into it.
What we're looking for
- High agency senior backend engineers (C#/.NET) or frontend engineers (React) who like making legacy systems better, not just writing new code from scratch.
- 6 to 12 years engineering experience.
- 6+ years of industry experience in programming web applications, mobile and/or large-scale enterprise products.
- Folks who use AI coding tools every day and want to design the systems that write code.
- Experience with AWS or Azure, CI/CD, testing and observability.
Why join
- A real modernization, with AI doing much of the heavy lifting. We're moving a 20-year-old .NET platform and a set of cloud services onto a modern architecture. Engineers set the target and review the work, and AI agents do most of the migration. Our new point-of-sale app was rebuilt with AI and loads 14× faster than the one it replaced.
- The team already works AI-first. Most of our code is written with Claude, and the team built its own AI-driven release monitoring. Next we're building a "software factory": agents that build, test and ship in parallel, while engineers review the spec, the code and the product.
- Hard problems that matter to customers. The work covers availability search, payments, memberships, orders and high-volume online booking.
- Momentum you can measure. In 2026 the team cut user-facing errors by 91% and stuck orders by 96%, and merchant NPS turned positive from -22 to +3.
- A high-leverage team. Booker sits inside a portfolio of products, so a small team gets to build on shared platform components it could never build alone, like design systems, infrastructure and AI products such as AI Concierge. Over the long term, Booker will move fully onto Playlist's shared payments, identity and infrastructure, so every improvement a platform team ships, we get for free.
- Ownership and autonomy. Engineers own the services they run, and decisions sit with the people closest to the work.
