10x Software Engineer

Lucidya

About The Position

Lucidya is a leading AI-powered Customer Experience Management (CXM) platform in the MENA region, enabling enterprises to understand, engage, and serve customers across digital channels at scale. As we move toward IPO-scale, we are rebuilding parts of our platform to achieve: Extreme reliability (SLO-driven engineering) High-scale distributed processing (billions of data points) AI-native architecture (LLM + real-time intelligence) We don’t optimize for titles, we optimize for impact! Whether you are junior or senior doesn’t matter and what matters is your ability to move faster and think deeper than the average engineer. We operate with extreme ownership. Problems don’t belong to teams or tickets where they belong to whoever sees them. The right person for this role doesn’t walk past a broken system. If something is failing, you fix it even if it’s not “your job.”

Requirements

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

Responsibilities

Microservices & Distributed Architecture
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
Performance & Systems
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
Observability & Reliability
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
Platform Evolution
Drive platform decoupling and service isolation across the system
Contribute to Kubernetes migration and infrastructure modernization
Standardize and improve CI/CD pipelines across services
