Dans ce rôle, vous vous concentrerez sur l’infrastructure IA/ML (la formation des modèles étant prise en charge par nos ingénieurs ML), en garantissant la fluidité des données dans les pipelines et la fiabilité des services d’inférence. Vous soutiendrez le produits IA Roam de Stay22 en développant des API et des services backend scalables pour l’inférence et l’analyse en temps réel, tout en créant des API et outils facilitant l’expérimentation rapide de l’IA à l’échelle de l’entreprise.

Principales responsabilités
  • Concevoir, développer et maintenir des pipelines et services d’IA/ML de bout en bout, de la préparation des données au déploiement des modèles et aux moteurs d’inférence en temps réel, pour soutenir les produits IA de Stay22.

  • Développer le backend et les API pour le moteur Roam (redirection basée sur ML) en garantissant évolutivité, performance et fiabilité.

  • Créer et maintenir des couches internes client/passerelle pour grands modèles linguistiques (LLM), permettant aux équipes produit d’exploiter ces modèles pour des fonctionnalités comme la suggestion de contenu ou la classification.

  • Collaborer avec l’équipe d’ingénierie ML pour intégrer les modèles entraînés dans les services de production et avec l’équipe Data pour optimiser les pipelines alimentant les modèles.

  • Travailler avec l’équipe Forge/plateforme pour mettre en place et maintenir l’infrastructure cloud (GCP), les pipelines CI/CD, la surveillance/journalisation et les meilleures pratiques de sécurité pour tous les systèmes IA.

  • Développer des services et outils internes pour les développeurs afin de faciliter l’expérimentation et l’adoption de l’IA, servant de « plateforme » interne d’IA/ML pour les autres équipes.

  • Veiller à ce que les systèmes backend soient bien documentés, maintenables et performants à grande échelle, en identifiant et résolvant les goulots d’étranglement, en mettant en œuvre des optimisations si nécessaire et en maintenant des normes élevées de qualité et de tests.

Expérience requise

  • Une bonne connaissance de l’anglais est requise pour communiquer au quotidien avec des collègues et des employés sous votre supervision à l’international.

  • Licence ou master en informatique ou domaine similaire, avec plus de 8 ans d’expérience en développement logiciel orienté systèmes backend.

  • Expérience dans le déploiement de services sur des plateformes cloud (idéalement Google Cloud Platform) et maîtrise des technologies de conteneurisation (Docker, Kubernetes). La connaissance de services GCP comme Vertex AI est un avantage.

  • Bonne maîtrise des bases de données relationnelles et NoSQL (ex. PostgreSQL, MongoDB) et des systèmes de gestion de tâches asynchrones (ex. Celery), avec expérience en optimisation de schémas et de requêtes.

  • Connaissance des workflows ML et des défis liés à la mise en production de modèles (pipelines de données, latence d’inférence, etc.). Une expérience avec l’infrastructure ML (Vertex AI, TensorFlow Serving ou équivalent) est un atout.

  • Compétences en CI/CD, tests automatisés et monitoring/alerting (logs, métriques, traçage) pour assurer fiabilité et sécurité des systèmes.

  • Excellentes capacités de communication et de collaboration : travailler efficacement avec les équipes ML, data et plateforme pour harmoniser interfaces et standards.

  • Autonomie et capacité à résoudre les problèmes de manière indépendante dans un environnement hybride.

About Stay22

Based in Montreal, Stay22 helps ambitious creators and intent-rich digital platforms turn their existing traffic into incremental revenue, with technology that works quietly in the background.

Today, more than 6,500 creators and platforms rely on Stay22, with over $1 billion in annual transactions flowing through the platform. Originally built for travel, the company now supports partners across retail, lifestyle, publishing, events, and transport as it expands its monetization infrastructure for the modern creator economy.

Position overview

As a Senior Fullstack Developer on Stay22's Neuro team, you will design and build robust backend systems that power our AI/ML infrastructure. Neuro's mission is to design, develop, and maintain the Roam engine - our machine-learning redirect system - along with underlying services like ML pipelines, model hosting, and LLM gateways. In this role you'll focus on the infrastructure side of AI/ML (model training is handled by our ML engineers), ensuring that data flows smoothly through ML pipelines and that inference services run reliably. You'll support Stay22's AI Roam product by building scalable backend APIs and services for real-time inference and analytics. You will also build APIs and tools that enable rapid AI experimentation across the company.

Key responsibilities

  • Architect, implement, and maintain end-to-end machine learning pipelines and services - from data preparation and model deployment to real-time inference engines - to support Stay22's AI products

  • Own the backend and API development for the Roam (ML-based redirection) engine, ensuring these services are scalable, performant, and reliable

  • Create and maintain internal Large Language Model (LLM) client/gateway layers that allow product teams to leverage language models for features like content suggestions or classification

  • Partner with the ML engineering team to integrate trained models into production services and work with the Data team to consume and optimize data pipelines feeding ML models

  • Coordinate with the Forge/platform team to implement and maintain cloud infrastructure (GCP), CI/CD pipelines, monitoring/logging, and security best practices for all AI-related systems

  • Build internal developer-facing services and tools that accelerate AI experimentation and adoption, effectively acting as an internal AI/ML “platform” to help other teams integrate Neuro's services

  • Ensure backend systems are well-documented, maintainable, and performant at scale. Identify and address performance bottlenecks, implement caching or optimizations as needed, and uphold high standards for code quality and testing.

Requirements

  • English proficiency is required for daily communication with international colleagues and direct reports.

  • Bachelor's or Master's degree in Computer Science or related field, with 8+ years of software development experience focusing on backend systems

  • Strong proficiency in Python and modern backend frameworks (e.g. FastAPI), with a track record of designing and building scalable APIs and microservices. (Experience with TypeScript/Node.js is not required for this role but welcomed)

  • Experience deploying services on cloud platforms (preferably Google Cloud Platform) and using container technologies (Docker, Kubernetes, etc.). Familiarity with GCP services like Vertex AI is a plus

  • Proficiency with relational and NoSQL databases (e.g. PostgreSQL, MongoDB) and asynchronous task queues (e.g. Celery). Hands-on experience optimizing database schemas and query performance

  • Understanding of machine learning workflows and the unique challenges of serving ML models (data pipelines, inference latency, etc.). Experience with ML infrastructure (Vertex AI, TensorFlow Serving, or similar) is advantageous

  • Skilled in setting up CI/CD pipelines, automated testing, and monitoring/alerting (logs, metrics, tracing) to ensure system reliability and security

  • Excellent communication and teamwork skills. You should be able to work closely with ML engineers, data engineers, and platform teams to align on interfaces and standards

  • Self-driven problem-solver who can work independently in a hybrid environment
