Senior Software Engineer, Backend

Peloton

SENIOR SOFTWARE ENGINEER, DATA FOUNDATIONS ABOUT THE ROLE At Peloton, we treat Data as a Product - a critical asset that powers every member interaction and business decision. The Datastores team’s mission is to provide a reliable, secure, highly available, and highly performant data persistence layer for application services across the company. Our guiding principles: 1. Protect the data, 2. Optimize for scale, speed, and reliability, 3. Eliminate toil. We are looking for a Senior Software Engineer with deep experience building and operating data-intensive systems to join our Datastores team. This role is ideal for a backend engineer who has built and operated production systems that rely heavily on databases, caching layers, and data pipelines, and who is excited to deepen their expertise in scalable, cloud-native data infrastructure. You will work at the intersection of application engineering and data platform reliability - partnering with service teams to improve how data is stored, accessed, scaled, and observed across Peloton’s ecosystem. YOUR DAILY IMPACT AT PELOTON You will: * Design, build, and operate backend systems that rely on scalable and highly available data persistence layers. * Partner with service teams to improve database design, query performance, and data modeling. * Contribute to automation around infrastructure provisioning using tools like Terraform and Backstage. Improve developer experience by building self-service tooling for databases and caching systems. * Work on observability, performance insights, and autoscaling strategies for production datastores. * Contribute to architectural decisions around multi-regional data persistence and global scalability. This role combines hands-on backend engineering with deep exposure to cloud data systems and platform reliability challenges. WHAT YOU BRING We’re looking for strong backend engineers who are “data-aligned” — meaning you’ve built systems where data performance, reliability, and modeling mattered. * 5+ years of software engineering experience building production backend systems. * Strong experience with relational databases such as PostgreSQL or MySQL, including schema design, indexing, and query optimization. * Experience working with NoSQL datastores such as DynamoDB, Redis, Elasticsearch, or Memcache. * Exposure to data pipelines, event-driven architectures, or systems that interface with streaming or batch processing frameworks. * Experience operating services in cloud environments (preferably AWS). * A strong understanding of distributed systems fundamentals: latency, consistency models, replication, and scaling strategies. * Experience running or tuning PostgreSQL or Aurora in production. * Experience with multi-region architectures. * Exposure to observability tooling (metrics, tracing, query insights). WHO YOU ARE * You think about data integrity first. * You care about performance and understand that small database decisions can have large system-wide impact. * You enjoy reducing manual toil through automation. * You collaborate well with application engineers and platform teams. * You want to grow deeper into database reliability, scalability, and cloud-native data systems.     ABOUT PELOTON: Peloton (NASDAQ: PTON) provides Members with expert instruction, and world class content to create impactful and entertaining workout experiences for anyone, anywhere and at any stage in their fitness journey.
