Senior Software Engineer (Backend)

• On this team, you will participate in major campaigns, contribute to our critical backend services, support multiple platforms, and play a key role in shaping and refining the overall backend architecture
• We are looking for a software engineer who is proactive, collaborative, and pragmatic with a passion for solving real-world problems. In this role, you will:
• Design and implement high-performance backend services in Elixir
• Architect and evolve microservices and distributed systems in Kubernetes
• Optimize systems for scale, resilience, observability, and security
• Collaborate with cross-functional teams to deliver pragmatic solutions to complex problems
• Explore and integrate AI-based development tools into daily workflows
• Work across service boundaries, own critical architecture/service design, and help evolve Tubi’s backend system
• This role goes beyond traditional engineering: you will extensively use AI to build the backend stack. The goal is to unlock smarter execution, faster delivery, and automation at scale, while ensuring responsible use of these technologies. This includes but not limited to:
• AI-Augmented Backend Development: Using AI-assisted coding tools (Claude Code, Cursor, etc.) to accelerate development while maintaining rigorous standards for correctness, security, and performance. You will set the bar for how backend engineers harness AI to iterate faster, write safer code, and document systems more effectively
• AI-Enhanced Architecture & Optimization: Exploring how AI can assist in system design, performance tuning, and anomaly detection across Tubi’s distributed backend. You will prototype and integrate AI-powered optimizations that improve throughput, reduce latency, and detect inefficiencies in large-scale microservice architectures
• AI-Driven Developer Experience: Contributing to internal tools and platforms that use AI to improve the daily developer workflow, ranging from automated code reviews and test generation to smarter observability dashboards. You will help evolve Tubi’s backend development culture into an AI-native practice
