Senior Backend Engineer Remote (10months FTC)

This role is ideal for a driven engineer who thrives on automation, optimization, and scalable infrastructure. You should bring deep backend experience and a strong understanding of LLMdriven workflows such as prompt engineering, RAG, and automated data pipelines.

Requirements:

• Design and deploy systems that eliminate manual processes, with strong emphasis on observability, reliability, and graceful failure recovery.
  
• Leverage LLMs to parse and process massive datasets, applying intelligent classification and refinement across iterative workflows.
• Build automation frameworks and tools that are scalable, maintainable, and reusable across Reddits content ecosystem

• What youll do:
  

  • Collaborate crossfunctionally with engineering, product, and data teams to align systems with product goals and longterm strategy.
    
  • Own the full development lifecycle: architecture, development, testing, experimentation, and launch.
    
  • Write clean, welldocumented code and contribute to design reviews, architecture decisions, and development standards.
    
  • Build and maintain APIs, middleware, and database structures to enable data interoperability across systems.
    
  • Troubleshoot performance bottlenecks, integration challenges, and ensure high system availability.
    
  • Uphold best practices in security, data privacy, testing, and documentation.
    
  • Proactively participate in agile rituals (planning, reviews, retrospectives), contributing to a hightrust, collaborative team culture.
    
  • Identify technical risks early and drive scalable solutions.

  • What youll do:
    

    • 8+ years of professional backend software development experience, ideally working on largescale distributed systems.
      
    • Expertise in Python (required), with proficiency in Go a strong plus.
      
    • Deep understanding of distributed systems, microservices architecture, and highthroughput application design.
      
    • Experience building and maintaining APIs (GraphQL and REST), as well as working with HTTP protocols.
      
    • Solid experience with technologies like Kafka, Redis, RabbitMQ, and both SQLNoSQL databases.
      
    • Familiarity with engineering best practices: CICD, test automation, AB testing, code reviews, and scalable documentation.
      
    • Strong system design skills with the ability to build maintainable data structures and workflows independently.
      
    • Clear, concise communication, comfortable collaborating in remote environments and across diverse teams.
      
    • BS in Computer Science or equivalent practical experience.

    • Bonus qualifications:
      

      • Handson experience with LLMs, RAG pipelines, or general MLAI infrastructure.
      • Previous work in content classification, search, or personalization systems.
      • Passion for building innovative tools in ambiguous, fastmoving environments.
