This is not an enterprise role for someone who works behind heavy layers of management or hides behind ticket boards. We are scaling a high-throughput, event-driven platform built on Golang, Node.js, Kafka, and GCP, and we need an engineer who can own features end-to-end-from initial system design to production deployment in Kubernetes. You must bring deep, real-world experience handling high-concurrency event streams and complex data layers. If you have a true startup builder's grit, take pride in high-impact coding exposure, and have the hands-on technical chops to conquer rigorous architectural assessments, we want to build with you., * Dual-Language Proficiency (Golang + Node.js): 5+ years of deep backend engineering experience with elite Golang proficiency as your main tool, plus strong production experience in JavaScript/TypeScript (Node.js). * Proven Kafka Expertise: Extensive, hands-on experience architecting and maintaining production event streams using Apache Kafka. You understand consumer groups, offset management, message delivery guarantees, and race conditions. * GCP & Kubernetes (K8s) Production Chops: Real-world experience deploying, running, and debugging containerized Go services within Google Cloud Platform (GCP) and Kubernetes. * High-Performance NoSQL Data: Advanced understanding of data modeling, caching strategies, and indexing in Redis and MongoDB. * Startup / 0-to-1 Track Record: Prior experience working in small, fast-moving engineering teams or early-stage startups where high coding volume, self-direction, and end-to-end feature ownership were required. * Assessment Readiness: Ability to pass a rigorous, hands-on technical assessment evaluating real-world Go concurrency, system design, and Kafka event handling. Preferred Qualifications (Nice to Have) * Quantitative/Math Aptitude: Strong mathematical background or intuition for solving complex calculation problems related to gaming ecosystems, mechanics, or financial data layers. * AI & Automation Curiosity: Basic exposure to or interest in integrating LLMs, autonomous agentic workflows, or meta-prompting strategies into microservices. * Timezone Alignment: Availability to align working hours between EST and Eastern Europe (EET) business hours for high-bandwidth engineering communication. ## Description * Core Distributed Backend Architecture: Design, write, and maintain high-throughput backend microservices utilizing Golang as your primary language, backed by Node.js (TypeScript). * Event-Driven & Kafka Mastery: Own and evolve our event-streaming infrastructure using Apache Kafka, handling complex partition strategies, message-ordering edge cases, and asynchronous workflows under heavy load. * Database & In-Memory Performance: Architect, scale, and optimize core data layers with heavy reliance on Redis for caching/pub-sub and MongoDB for flexible document indexing. * Production Deployment & Cloud Alignment: Deploy and manage your services within Google Cloud Platform (GCP) and Kubernetes (K8s) environments, taking complete ownership of service reliability. * 0-to-1 Feature Execution: Rapidly translate ambiguous product requirements into clean, scalable RESTful and GraphQL APIs without waiting for hand-holding. * Algorithmic & Quantitative Problem Solving: Solve complex backend calculations natively within business logic (e.g., gaming mechanics, payout engines, or financial transaction loops). ## Related Videos - [Leveraging Real time data in FSIs](https://www.wearedevelopers.com/videos/806-leveraging-real-time-data-in-fsis) - [Inside Bitpanda's Tech Stack: Scaling a European Fintech Leader - Markus Dorner](https://www.wearedevelopers.com/videos/1979-inside-bitpanda-s-tech-stack-scaling-a-european-fintech-leader-markus-dorner) - [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) - [Go with the Flow: Stop the Leaks Before Your Memory's a Waterfall!](https://www.wearedevelopers.com/videos/100073-go-with-the-flow-stop-the-leaks-before-your-memory-s-a-waterfall) - [Scoring 2000 Products per Request: Performance Pitfalls in Golang](https://www.wearedevelopers.com/videos/2073-scoring-2000-products-per-request-performance-pitfalls-in-golang) - [Monoskope: Developer Self-Service Across Clusters](https://www.wearedevelopers.com/videos/329-monoskope-developer-self-service-across-clusters) ## Related Articles - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [7 Most Popular Web Developer Jobs in Europe](https://www.wearedevelopers.com/magazine/163-7-most-popular-web-developer-jobs-in-europe) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline)
