Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Sr Software Engineer - **Company:** The Playlist LLC - **Location:** United States (Remote available) - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** .NET Framework, Artificial Intelligence, Amazon Web Services, Microsoft Azure, C Sharp (Programming Language), Continuous Integration, Cloud Services, Software Factory, Web Applications, ReactJS, AI Coding Agents, Backend, Agentic-AI, Front End Software Development, Claude, Legacy Systems - **Published:** November 13, 2026 - **Apply:** https://arc.dev/remote-jobs/j/redirect/pyvtmhf532 ## About the Role * 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. ## Description * 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. Have we piqued your curiosity? Sound like the role for you? We'd love to hear from you!
