Unification: bring dozens of fragmented systems under one standard (data models, auth, account linking, filters, pagination) On-prem: connect to SQL-, DLL- and API-based systems built 20-40 years ago and add real-time communication and webhooks where none exist Scale and speed: millions of API requests a day, caching and storage layers, shipping code daily Operational excellence: a reliable, SLA-backed API layer with testing across 1k+ endpoints Front end too: build apps that dog-food the APIWhat they're looking for:1-5 years as a back-end or full-stack engineer who can work independently Undergrad CS degree Recent Seed-Series D startup experience, or a clear desire to join a startup Familiarity with AWSSelf-motivated, high ownership, low ego Tech: PostgreSQL, Redis, AWS
