Senior Backend Engineer — Core Components at Dailymotion

About the team  The Core Toolkit team sits within Core Video & Operations and acts as a force multiplier for engineering at Dailymotion. We build the self-serve APIs, platforms, and operational components that every team relies on daily to ship safely and efficiently.    Our scope covers four critical internal systems:  • Administration BFF :  the central gateway for all internal operations, with built-in security, request traceability, and full change historization  • Async task orchestration :  the backbone of our micro-service stack, handling scheduling, queuing, and orchestration for all asynchronous and recurring workloads across the platform  • Feature flipping system :  managing 500+ feature flags and enabling safe rollouts and experimentation across the entire platform  • Operational logging infrastructure :  providing audit trails and observability for internal operations  We're a small, autonomous team where each engineer has real ownership and direct impact on how Dailymotion operates at scale.    What you'll do 🏗️ Build and own critical infrastructure • Take full ownership of our administration BFF,  from security architecture and request traceability to change historization and API design that powers internal teams • Lead the evolution of our async task orchestration platform,  the backbone of our microservices ecosystem,  making it more reliable, scalable, and developer-friendly • Scale our feature flipping system to fuel experimentation across all product teams 🚀 Drive technical modernization • Dissect legacy architectures and craft pragmatic modernization strategies,  deciding what to refactor, rebuild, or strategically leave untouched • Shape the technical roadmap by partnering with internal stakeholders, turning their pain points into impactful improvements ⚡ Leverage cutting-edge tools and practices • Use AI-powered development tools (GitHub Copilot, Claude, ChatGPT) strategically to accelerate delivery, from development and testing to documentation and debugging • Elevate engineering standards through thoughtful code reviews, testing strategies, clean documentation, and active knowledge sharing 🤝 Enable and empower teams • Support engineers across the organization by providing expert guidance on the administration API, task orchestration, logging systems, and feature management  Our current stack • Core — Python (microservices), PHP (legacy) | REST, GraphQL, OpenAPI • Infrastructure — Docker, Kubernetes, Helm | AWS, GCP | JX (Jenkins X) • Data — Elasticsearch, MySQL, MongoDB | RabbitMQ, NSQ • Security — OAuth, JWT, RBAC, Vault • Observability — Datadog, distributed tracing | GitHubComing soon : Go is joining the stack with multiple upcoming projects, so experience with it is a strong plus
