Job Summary
We are seeking an exceptional Senior Golang Engineer to architect and scale the core infrastructure powering our Online Travel Agency (OTA)(Hojuzat). You will be building the high-performance backend systems that process millions of daily flight and hotel searches aggregate live inventory from dozens of global suppliers and return unified results to our users in milliseconds.
This role requires a deep understanding of distributed systems aggressive caching strategies and highly concurrent execution. You will tackle complex challengessuch as standardizing massive datasets from disparate travel APIs implementing scatter-gather patterns for real-time pricing and ensuring sub-second response times across a global inventory of hotels and flights.
Key Responsibilities
Sub-Second Search Architecture: Architect and optimize our core search engine to instantly query millions of hotel properties room types and flight itineraries. Utilize memory-efficient data structures and search indices (e.g. Elasticsearch Redis) to ensure strict low-latency SLAs.
Supplier & GDS Integrations: Build fault-tolerant integrations with external travel suppliers Global Distribution Systems (GDS) and bedbanks (e.g. Amadeus Sabre Hotelbeds Expedia Affiliate). Handle complex mappings rate limits and slow third-party responses gracefully using circuit breakers and timeouts.
Concurrent Data Aggregation: Leverage Gos concurrency model (goroutines channels waitgroups) to execute highly parallel "scatter-gather" requests fetching live availability and pricing from multiple suppliers simultaneously and merging them in real-time.
Caching & Real-Time Availability: Design sophisticated multi-layered caching strategies to serve fast hotel searches while ensuring pricing accuracy and availability during the final booking flow.
Event-Driven Booking Flows: Develop robust asynchronous pipelines using message brokers (Kafka / RabbitMQ) to handle booking events payment confirmations and background inventory syncs without blocking the user journey.
Cross-Functional Leadership: Mentor mid-level engineers lead technical design document (RFC) reviews and collaborate with product teams to design scalable API contracts for our web and mobile clients.
Requirements
Experience: 6 years of software engineering experience with at least 4 years dedicated to building production-grade high-throughput backend systems in Go.
High-Performance Search & Caching: Strong hands-on experience with in-memory datastores (Redis) and distributed search/analytics engines (Elasticsearch / Meilisearch / OpenSearch) to power sub-second query responses.
Complex API Integrations: Proven track record of integrating disparate complex third-party APIs (REST gRPC and legacy SOAP/XML heavily used in the travel industry).
Concurrency & Go Mastery: Deep expertise in Gos concurrency patterns memory management and performance profiling (pprof) under sustained high-traffic load.
Resilient Systems: Experience implementing distributed system resilience patterns (Circuit Breakers Retries with Exponential Backoff Bulkheads) to protect our platform from third-party supplier outages.
Infrastructure: Proficiency with containerization and orchestration (Docker Kubernetes) and working within modern CI/CD pipelines.
Preferred Qualifications
Travel Tech Domain Knowledge: Previous experience working at an OTA meta-search engine or hospitality tech company. Familiarity with travel industry standards (NDC OTA XML schemas) is a massive plus.
Geospatial Search: Experience working with Geo-queries (PostGIS Redis GEO Elasticsearch Geo-shape) to power radius-based hotel searches and map views.
Revenue/Pricing Engines: Understanding of dynamic pricing algorithms markup rules engines or currency conversion systems.
Required Skills:
Technical Skills Strong understanding of: Security Operations & Incident Response Networking (TCP/IP DNS HTTP TLS) Linux systems Hands-on experience with: SIEM platforms (Splunk Elastic Wazuh Sentinel QRadar etc.) EDR / Endpoint Security Firewalls WAFs IDS/IPS Experience analyzing: Logs network traffic alerts and system behavior Cloud & Modern Environments Experience with cloud environments (AWS GCP Cloudflare) Familiarity with containers and Kubernetes security is a plus Understanding of IAM API security and application logs Regulatory Awareness (Highly Preferred) Knowledge of Saudi cybersecurity regulations: NCA ECC / CCC SAMA CSF (for regulated environments) CST requirements Experience supporting regulatory audits is a strong advantage. Qualifications Bachelors degree in Computer Science Information Security or related field 36 years experience in SOC security operations or incident response Certifications (preferred but not mandatory): GCIA GCIH GCED CEH Security ISO 27001 or SOC-related certifications Soft Skills Strong analytical and problem-solving skills Ability to stay calm under pressure during incidents Clear documentation and communication skills Team player with a security-first mindset High sense of ownership and accountability
