Senior Backend Engineer, Dailymotion

• 5+ years of backend engineering experience building and operating production systems at scale
• Polyglot engineering mindset : you've worked with multiple languages throughout your career and pick the right tool for the job (e.g., Python, Go, PHP, Java, TypeScript)
• Strong backend fundamentals : API design (REST, GraphQL), authentication/authorization, distributed systems, async processing, and queueing systems
• Hands-on experience with AI-assisted development workflows : you know how to use AI tools strategically while understanding their limitations
• Database expertise across relational and NoSQL systems : data modeling, query optimization, and operational trade-offs
• Cloud & infrastructure fluency : (AWS, GCP, or Azure) with hands-on experience in containerized environments (Docker, Kubernetes)
• Architectural judgment : you can dissect a legacy system, identify what matters, and design a pragmatic path forward
• Ownership & communication : you drive topics end-to-end and communicate clearly with both engineers and non-technical stakeholders
• Fluent in French (Mandatory)
• Don't check every box? Apply anyway
• We're looking for the right person to join the team, not just a perfect resume. If this role excites you but your experience doesn't align perfectly with every requirement, we still want to hear from you

Desirable

• 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
• 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 | GitHub
• Coming soon : Go is joining the stack with multiple upcoming projects, so experience with it is a strong plus

• HR Interview with Marvin (30 min): Get to know each other, discuss your motivations, and align on role expectations
• Manager Interview with Raphaël, your future manager (45 min): Deep dive into the role requirements, assess your technical background and problem-solving approach, and challenge your skills through concrete scenarios
• Technical Case Study (1 hour) : Work on a take-home case study followed by a presentation to Raphaël and a team member, this gives you a chance to showcase your technical thinking and understand what you'd be working on, while helping us evaluate the fit with our needs
• Leadership Interview with N+2 (1 hour) : Discuss long-term career goals, understand how this role fits into Dailymotion's broader strategy, and explore growth opportunities within the organization
