Job description

Level Shoes runs its backend on Vapor-based microservices, and this Server-Side Swift Developer role joins that team to build and operate the services powering iOS, Android and web storefronts across six GCC markets in English and Arabic. Production ownership runs deep here, covering design, implementation, code review, deployment and how services actually behave under sale-day load or when integrated systems misbehave. You'll build and maintain the RESTful APIs behind commerce flows like accounts and authentication, catalogue, cart, checkout, payments and orders, ensuring correctness across every store, market and locale. Third-party integrations span the commerce platform, order management, search, CMS and payment or BNPL gateways, including webhook handling and safe degradation when those systems slow down or go offline. Concurrency-safe, idempotent processing keeps operations running correctly across multiple service replicas, while MongoDB handles data modelling and query optimisation and Redis powers caching and session strategies. Search and listing functionality runs on Elastic Search, tuned and implemented directly, with behaviour changes shipped behind feature flags through staged, measured rollouts. Investigating production issues from logs and metrics happens routinely, fixes get validated against evidence, and CI/CD pipelines and deployment workflows on Kubernetes stay maintained throughout. AI-driven capabilities like vector search for personalisation get explored too, and every piece of code goes through teammate review before merge, regardless of seniority. Six or more years of professional software development experience is required, including at least 3 years building production backend services in server-side Swift with Vapor, since client-side Swift alone doesn't satisfy this requirement.
