Preferred Experience * Experience engineering distributed double-entry ledgers, transactional wallets, or high-volume payment processing engines. * Hands-on work with high-frequency sports data feeds and dynamic leaderboard calculation engines. * Experience decoupling monolithic architectures into scalable event-driven services. ## Description We are looking for a Senior Backend Engineer to design, scale, and maintain high-throughput, mission-critical distributed systems serving millions of concurrent users. In this role, you will lead the architecture of core platform domains-ranging from high-frequency real-time event streaming and financial ledgers to complex sports data ingestion pipelines and identity services., * Scalable Architecture & Design: Architect resilient, low-latency microservices in Go capable of handling peak burst traffic during high-profile live events. * High-Throughput Streaming & Real-Time Engines: Build and optimize end-to-end data ingestion pipelines, WebSocket/SSE engines, and event streams for real-time match processing, analytics, and instant state synchronization. * Transactional Integrity & Financial Systems: Design double-entry wallet/ledger architectures, token economies, and payment pipelines with strict zero-loss consistency, idempotency, and auditability. * Data Layer Optimization: Own database modeling, partitioning strategies (sharding/range partitioning), query optimization, and connection lifecycle management in high-load PostgreSQL environments. * Platform Security & Compliance: Enforce enterprise-grade security standards across identity (OAuth 2.0/OIDC), PII protection, and compliance boundaries (PCI-DSS, SOC 2, KYC). * System Reliability & Observability: Implement comprehensive distributed tracing, metrics, and alerting to maintain 99.99% system availability under volatile loads. * Technical Leadership: Lead system design reviews, drive engineering best practices, and mentor intermediate engineers across backend squads. ## Related Videos - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [Reducing LLM Calls with Vector Search Patterns - Raphael De Lio (Redis)](https://www.wearedevelopers.com/videos/1714-reducing-llm-calls-with-vector-search-patterns-raphael-de-lio-redis) - [Scaling: from 0 to 20 million users](https://www.wearedevelopers.com/videos/676-scaling-from-0-to-20-million-users) - [Get started with securing your cloud-native Java microservices applications](https://www.wearedevelopers.com/videos/123-get-started-with-securing-your-cloud-native-java-microservices-applications) - [Delay the AI Overlords: How OAuth and OpenFGA Can Keep Your AI Agents from Going Rogue](https://www.wearedevelopers.com/videos/1637-delay-the-ai-overlords-how-oauth-and-openfga-can-keep-your-ai-agents-from-going-rogue) - [Tracking vehicles at scale](https://www.wearedevelopers.com/videos/1999-tracking-vehicles-at-scale) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [The 7 Most Popular Backend Frameworks for Developers](https://www.wearedevelopers.com/magazine/403-the-7-most-popular-backend-frameworks-for-developers) - [20 Essential Tools For Backend Development](https://www.wearedevelopers.com/magazine/218-20-essential-tools-for-backend-development) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [The Best X (Twitter) Accounts for Developers](https://www.wearedevelopers.com/magazine/294-the-best-x-twitter-accounts-for-developers) - [What’s the Difference Between Frontend and Backend Development?](https://www.wearedevelopers.com/magazine/240-what-s-the-difference-between-frontend-and-backend-development)
