Backend Engineer, UI Platform

The shape of it

In the posting’s own words

The UI Platform team, known as Sail, builds the foundations behind Stripe’s Dashboard and many other user interfaces. Sail Services owns the systems that evaluate feature flags and experiments, ingest frontend analytics, and improve Dashboard load times for Stripe’s largest merchants.

What it asks for · 6

• Fluency in using AI-assisted and agentic development tools as part of day-to-day software engineering, including critically reviewing, validating, and improving generated code
• 2+ years of professional software engineering experience, or equivalent practical experience, building, shipping, and operating production systems
• Strong knowledge of backend technologies and infrastructure, including the fundamentals of APIs, data storage, distributed systems, and production operations
• Ability to independently scope and deliver open-ended software projects, making practical technical and product tradeoffs with limited oversight
• Strong problem-solving and debugging skills, with attention to testing, maintainability, reliability, and user impact
• Strong written and verbal communication skills and the ability to collaborate effectively with frontend engineers, product engineers, and infrastructure partners

Also a plus

• Experience building backend-for-frontend systems, UI platform services, developer platforms, or shared infrastructure
• Experience designing or integrating APIs, including GraphQL APIs
• Experience with high-throughput event ingestion, feature flag or experimentation systems, or other latency-sensitive platform services
• Familiarity with caching, asynchronous systems, configuration systems, or data-consistency tradeoffs
• Experience executing large migrations using automated validation, shadow traffic, feature flags, or staged rollouts
• Experience using data, developer feedback, or operational signals to improve a platform or developer-facing product

What the job covers

• Take end-to-end ownership of software projects, aligning on priorities and then independently scoping problems and carrying solutions through design, implementation, testing, rollout, and operation
• Design, build, and operate reliable, scalable APIs and backend systems that support Stripe’s Dashboard, mobile applications, and other user interfaces
• Help modernize Stripe’s UI architecture through incremental migrations, automated validation, shadow traffic, and carefully controlled production rollouts
• Improve the reliability, observability, performance, and operability of services on critical user paths
• Partner with frontend, backend, and infrastructure engineers to understand their needs and turn recurring problems into reusable platform capabilities
• Use AI-assisted and agentic development workflows to improve implementation, testing, validation, and delivery
• Contribute thoughtful code reviews, technical discussions, documentation, and runbooks that improve the quality of the team’s work
