10x Software Engineer

• Extreme reliability (SLO-driven engineering)
• High-scale distributed processing (billions of data points)
• AI-native architecture (LLM + real-time intelligence)

• Design and operate high-throughput, event-driven pipelines across a 100+ microservice ecosystem handling billions of data points
• Build and scale distributed messaging systems with RabbitMQ, backpressure management, consumer scaling, and queue health
• Develop and maintain API gateway layers with advanced routing (multi-upstream, traffic splitting, environment isolation)
• Architect SSO and identity federation for enterprise clients, supporting multi-IdP routing with zero coupling to core services
• Define clean service boundaries across ingestion, processing, and delivery pipelines spanning Ruby and Python

• Diagnose and resolve complex production issues (e.g., deadlocks, queue exhaustion, connection pool saturation) — and eliminate root causes
• Optimize PostgreSQL for heavy write workloads, contention management, schema design, triggers, and connection scaling
• Design and tune Elasticsearch for search, indexing, and real-time Arabic relevance at scale
• Make informed trade-offs between multi-process and async architectures based on workload characteristics

• Build and maintain observability across a large-scale system using Grafana, Loki, distributed tracing, and SLOs
• Own production incidents end-to-end, tracing failures across queues, search systems, and external integrations
• Lead root cause analysis and implement preventative measures across multi-service pipelines
• Build internal tooling that improves engineering velocity, automation, deployment gating, and review enforcement
• Turn architectural principles into enforceable standards and guardrails, not just documentation

• Drive platform decoupling and service isolation across the system
• Contribute to Kubernetes migration and infrastructure modernization
• Standardize and improve CI/CD pipelines across services

• Strong foundation in distributed systems. You understand failure modes before you write the first line
• Hands-on experience with event-driven architecture and message queues in production
• Deep comfort with concurrency, backpressure, and fault tolerance
• Track record debugging complex production issues — not just fixing them, preventing them
• Experience with Rails or Python backends at meaningful scale
• You improve systems you weren’t asked to touch

• Read and understand an existing codebase by week one
• See a broken system and fix it before anyone asks you to
• Have strong opinions about architecture and can back them up with data
• Think in systems: latency, throughput, failure modes, and cost at scale
• Treat documentation, tests, and observability as non-negotiable defaults and not afterthoughts
• Ship fast and without breaking things. Speed and quality are not a trade-off for you
• Consistently exceed expectations where meeting the bar is a floor, not a target
• Are hungry for hard challenges and actively seek problems at the edge of your limits
• Feel a sense of urgency that doesn’t require external pressure
• Have rebuilt or stabilised something significant and can talk about it concretely

• Real scale with billions of events and not just toy systems
• Direct impact at CTO and executive level
• Pre-IPO with clear trajectory and your work has real impact on clients
