Senior Backend Engineer — Core Components

Company Description:

Dailymotion is more than a video app, it's a visual conversation in motion, based on a unique algorithm designed to broaden users' horizons. Dailymotion brings nuance to the debates that animate young people and puts listening, discovery, and kindness back at the heart of interactions to help build a better and safer Internet.

Dailymotion is also "Dailymotion Pro", a video hosting and broadcasting solution for professionals in all sectors; and "Dailymotion Advertising", a powerful, proprietary video advertising platform, offering a high-quality, secure environment for brands.

Our team is made up of 400 people in France, New York, Singapore, Milan, Madrid and London all united by the same ambition: to visibly shake up the global video platform ecosystem.

Job Description:

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 | GitHub

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

   

  Qualifications:

  Required

  • 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)
    
     

    Nice to have

    Experience migrating or modernizing legacy systems in a production environment

    Background in audit logging, traceability, and compliance-oriented architectures

    Familiarity with high-throughput systems handling millions of requests per day

    Strong interest and hands-on experience with Go,  it's a key part of Dailymotion's tech stack and will be central to many upcoming projects
