What you'll be doing We are looking for a Server-Side Swift Developer to join the backend team at Level Shoes. The team builds and operates the Vapor-based microservices that power our iOS, Android and web storefronts across six GCC markets in English and Arabic. This is a hands-on senior role with real production ownership. You will design, build, review and ship backend services, and you will be accountable for how they behave in production — including under sale-day load and when the systems we integrate with misbehave. • Design, develop and maintain scalable backend services in Swift using Vapor. • Own services end to end: design, implementation, code review, deployment and production health. • Build and maintain the RESTful APIs behind customer-facing commerce flows — accounts and authentication, catalogue, cart, checkout, payments and orders. • Ensure correctness across multiple stores and languages, where every request is scoped to a market and a locale. • Design and maintain integrations with third-party systems — commerce platform, order management, search, CMS, and payment/BNPL gateways — including webhook handling and safe degradation when those systems are slow or unavailable. • Build concurrency-safe, idempotent processing for operations that run across multiple service replicas and must never be applied twice. • Model data and optimise queries in MongoDB; implement caching and session strategies in Redis. • Implement and tune Elastic Search-backed search and listing functionality. • Ship behaviour changes behind feature flags with staged, measured rollouts. • Investigate production issues from logs and metrics, and validate fixes with evidence. • Maintain CI/CD pipelines and deployment workflows on Kubernetes. • Explore AI-driven capabilities such as vector search for personalisation. • Review teammates' changes; all code is reviewed before merge regardless of seniority. What you’ll need to succeed - 6+ years of professional software development experience, including at least 3 years building production backend services in server-side Swift (Vapor). Client-side Swift alone does not satisfy this requirement — the role requires Swift running on a server, under load, with a database behind it. Prior iOS/macOS or backend experience in other languages is welcome for the remaining years. • Strong command of Swift concurrency, protocol-oriented design and Codable, including decoding payloads from external systems. • Demonstrable experience with concurrency, race conditions and idempotency in services running as multiple instances — a specific production bug you found, diagnosed and fixed, not theoretical knowledge. • Strong understanding of RESTful API design, authentication and token lifecycle. • MongoDB in production, including data modelling, indexing and query performance. • Redis for caching and session state, including graceful behaviour when it is unavailable. • ElasticSearch for search and listing. • Experience integrating payment gateways and third-party APIs, including webhook-driven flows. • Kubernetes: deploying and operating containerised services, and reading logs and metrics to a defensible conclusion. • Git, CI/CD pipelines and automated testing; Swift Package Manager for dependency management. • Strong grasp of performance, scalability and security best practices. • E-commerce, payments or ano
