Sr Software Engineer - Playlist

Job Description

The Role You'll Play

You’ll build and operate the backend systems that power Playlist. This is a senior, hands-on role focused on distributed systems, data modeling, and pragmatic system design—delivering reliable services at scale while keeping the architecture simple and maintainable. You’ll also operate at the edge of what’s possible by leveraging AI (LLMs and agentic tooling) to accelerate delivery, improve quality, and push system capabilities forward.

• Partner with Product and Design to deliver features from ideation through deployment, iterating based on feedback and outcomes
• Design and ship backend services and APIs end-to-end, owning system design and architecture decisions across service boundaries, data ownership, consistency models, failure modes, and others
• Model and store data thoughtfully: schema design, indexing/partitioning, migrations, and performance tuning
• Promote engineering excellence by driving simplicity, strengthening operational health, and upholding quality through automated testing, code reviews, and monitoring/observability
• Mentor teammates and raise the bar for engineering rigor and clarity, including best practices for responsible AI usage

What We're Looking For

• 8+ years building and operating backend systems for high-traffic and high-reliability products
• Strong system design skills across distributed systems (latency, throughput, durability, backpressure, idempotency, retries, timeouts)
• Deep understanding of data modeling and persistence (relational and/or NoSQL), including tradeoffs around normalization, transactions, and consistency
• Experience designing service-oriented architectures (microservices or modular monoliths), including service-to-service communication patterns
• Solid CS fundamentals and engineering judgment, proficiency in an OO language (e.g., Java/Kotlin/C#), and a solid understanding of SDLC and Agile methodologies
• AI-native builder mindset with strong judgment; understanding of AI tooling such as MCPs, evals, RAG are good to have
• Strong communication and collaboration across functions

Tools and Systems

You don’t need experience with every item below—what matters is strong fundamentals and the ability to learn quickly.

• Languages and Frameworks: Java/Kotlin/C#, SpringBoot/NetCore. async/concurrency, RPC/REST
• Data: PostgreSQL/MongoDB/DynamoDB, Redis, schema migrations, indexing, partitioning/sharding
• Runtime & tooling: gradle, monorepos, CI/CD
• Testing: unit/integration/e2e testing (JUnit/Mockito/TestContainers)
• Observability: metrics/logging/tracing; New Relic/Datadog/Kibana/Grafana
• AI tooling: Claude Code/ Cursor/ Codex-style coding assistants; MCPs; agent/orchestration frameworks; safety harnesses
• Engineering Practices: automated testing, code reviews, CI/CD, observability, on-call, incident management — with AI-accelerated workflows where appropriate
