Staff Full-Stack Engineer (more Backend and Architecture tasks)

Що робити

Take ownership of architectural decisions across backend services, including service boundaries, data ownership, idempotency, outbox patterns, caching, and failure handling.
Document important technical decisions and revisit them as requirements and system constraints evolve.
Design and evolve financially sensitive functionality, including double-entry wallet accounting, payments and withdrawals, inventory settlement, and auditable outcome-generation mechanisms.
Work across layers when necessary, from database schemas and Drizzle migrations through domain logic, Fastify APIs, asynchronous consumers, and React interfaces.
Provide technical leadership for the internal operations platform supporting catalog, fulfillment, finance, and customer-support workflows.

8–9+ years of professional software engineering experience, including several years with direct responsibility for architecture and technical decisions in production systems.
Proven experience defining service boundaries, selecting appropriate storage technologies, and scaling production systems.
Practical understanding of capacity planning, caching strategies, database connection management, performance bottlenecks, and production debugging.
Ability to evaluate architectural trade-offs such as consistency vs. availability, synchronous vs. asynchronous communication, caching vs. source-of-truth access, and build vs. buy decisions.
Strong server-side engineering background with Node.js/TypeScript, .NET, or Java. Engineers coming from .NET or Java should be comfortable transitioning to TypeScript.
