  • Develop and improve agentic AI workflows that support code understanding, refactoring, validation, and modernization.
  • Modernize existing desktops, simulation, and engineering applications into cloud-native services and modern architectures.
  • Use loop engineering approach to improve quality, reduce costs and accelerate the conversion/test/correction process.
  • Evaluate and improve AI systems for accuracy, reliability, performance, observability, and cost efficiency.
  • Create automated tooling, validation frameworks, and testing strategies to ensure correctness of transformed code.
  • Partner with architects, product leaders, and engineering teams to identify modernization opportunities and drive adoption.
  • Contribute to technical direction, best practices, and reusable modernization frameworks that can be leveraged across Bentley.
  • Help establish and share expertise in a rapidly evolving AI domain.
  • This role does not require travel.
  • Requires sitting or standing at will while performing work on a computer (or any other physical requirements ).

 

Required Qualifications

  • Strong software development background with ownership of production systems.
  • Experience building, maintaining, or modernizing complex software applications.
  • Demonstrated understanding of software performance, reliability, scalability, testing, and failure modes.
  • Practical experience applying AI, machine learning, inference pipelines, optimization techniques, or intelligent automation to real-world problems.
  • Systems-oriented mindset with the ability to bring structure to ambiguous technical challenges.
  • Experience designing pipelines, feedback loops, iterative systems, or large-scale developer tooling.
  • Strong communication skills and the ability to collaborate with technical and non-technical stakeholders.

 

Preferred Qualifications

  • Experience with Rust, C++, C, or Fortran.
  • Experience modernizing legacy systems or migrating applications to cloud-native architectures.
  • Background in DevOps, CI/CD pipelines, testing frameworks, simulation systems, benchmarking, or validation tooling.
  • Experience working with engineering, scientific, mathematical, or simulation software.
  • Familiarity with cloud platforms and distributed systems.
  • Interest in emerging AI development patterns, agentic workflows, and software transformation technologies.

 

What Success Looks Like

Successful candidates will demonstrate the ability to:

  • Modernize existing systems rather than only building greenfield solutions.
  • Make thoughtful tradeoffs between performance, reliability, latency, maintainability, and cost.
  • Apply AI in practical, production-oriented ways.
  • Navigate ambiguity while maintaining engineering rigor.
  • Build systems that continuously improve and scale over time.

 

Who Thrives in This Role

  • Developers who enjoy applying AI to real-world engineering challenges and measuring success through production impact.
  • Builders who are comfortable working within large, evolving codebases.
  • Generalists who enjoy moving across languages, tools, and technical domains.
  • Developers who embrace continuous learning as AI capabilities and modernization approaches evolve.

Développeur principal, modernisation du code par l’IA

Lieu : Hybride – Québec, Canada

Résumé du poste

Bentley met sur pied une équipe spécialisée en modernisation du code par l’IA, axée sur l’application de techniques avancées d’intelligence artificielle pour transformer des systèmes logiciels d’ingénierie à grande échelle. Cette équipe est responsable du développement de pipeline de modernisation alimentées par l’IA afin de contribuer à la migration et à l’évolution d’applications complexes, notamment des bases de code scientifiques et d’ingénierie, vers des architectures modernes infonuagiques.

Il s’agit d’un rôle d’ingénierie appliqué et non de recherche académique. Vous travaillerez à l’intersection du génie logiciel, des systèmes d’IA, des outils de développement et de l’automatisation de la modernisation. Le succès sera mesuré par l’impact en production, l’évolutivité, la fiabilité et la capacité à accélérer la modernisation dans l’ensemble du portefeuille de produits de Bentley.

Ce que vous ferez

  • Concevoir et bâtir des pipelines de modernisation logicielle pilotées par l’IA.
  • Développer et améliorer des flux de travail d’IA agentique qui soutiennent la validation et la modernisation.
  • Moderniser des applications « desktop » de simulation et d’ingénierie existantes en services infonuagiques et en architectures modernes.
  • Utiliser une approche d’ingénierie en boucle (« loop engineering ») pour améliorer la qualité, réduire les coûts et accélérer le processus de conversion, de test et de correction.
  • Évaluer les systèmes d’IA en matière d’exactitude, de fiabilité, de performance, d’observabilité et d’efficacité des coûts.
  • Créer des outils automatisés, des cadres de validation et des stratégies de test pour assurer l’exactitude du code transformé.
  • Collaborer avec les architectes, les responsables de produits et les équipes d’ingénierie afin d’identifier les possibilités de modernisation et d’en favoriser l’adoption.
  • Contribuer à l’orientation technique, aux pratiques exemplaires et aux cadres de modernisation réutilisables pouvant être mis à profit dans l’ensemble de Bentley.
  • Aider à établir et à partager une expertise dans un domaine de l’IA en évolution rapide.
  • Ce rôle ne nécessite aucun déplacement.
  • Exige de pouvoir rester assis ou debout au besoin pendant le travail à l’ordinateur ou toute autre exigence physique applicable.

Qualifications requises

  • Solide expérience en développement logiciel
  • Expérience dans la création, la maintenance ou la modernisation d’applications logicielles complexes.
  • Compréhension démontrée de la performance logicielle, de la fiabilité, de l’évolutivité, des tests et des modes de défaillance.
  • Expérience pratique dans l’application de l’IA, de l’apprentissage automatique, des chaînes d’inférence, des techniques d’optimisation ou de l’automatisation intelligente à des problèmes concrets.
  • Être orienté systèmes, avec la capacité de structurer des défis techniques ambigus.
  • Expérience dans la conception de pipeline de traitement, de boucles de rétroaction, de systèmes itératifs ou d’outils de développement à grande échelle.
  • Excellentes compétences en communication et capacité à collaborer avec des parties prenantes techniques et non techniques.

Qualifications souhaitées

  • Expérience avec Rust, C++, C ou Fortran.
  • Expérience en modernisation de systèmes patrimoniaux ou en migration d’applications vers des architectures infonuagiques.
  • Expérience en DevOps, pipeline CI/CD, cadres de test, systèmes de simulation, bancs d’essai ou outils de validation.
  • Expérience avec des logiciels d’ingénierie, scientifiques, mathématiques ou de simulation.
  • Familiarité avec les plateformes infonuagiques et les systèmes distribués.
  • Intérêt pour les nouveaux modèles de développement en IA, les flux de travail agentiques et les technologies de transformation logicielle.

À quoi ressemble la réussite

Les candidats retenus démontreront leur capacité à :

  • Moderniser des systèmes existants plutôt que de se limiter à créer de nouvelles solutions.
  • Faire des compromis réfléchis entre performance, fiabilité, latence, maintenabilité et coût.
  • Appliquer l’IA de manière pratique et orientée production.
  • Naviguer dans l’ambiguïté tout en maintenant une grande rigueur d’ingénierie.
  • Construire des systèmes qui s’améliorent continuellement et qui évoluent avec le temps.

Qui réussit dans ce rôle

  • Les développeurs qui aiment appliquer l’IA à des défis d’ingénierie concrets et mesurer le succès par l’impact réelle pour les utilisateurs.
  • Les développeurs qui sont à l’aise à faire évoluer des systèmes complexes.
  • Les généralistes qui aiment travailler avec différents langages, outils et domaines techniques.
  • Les développeurs qui sont comfortable à se garder à jour avec l’IA et les approches de modernisation qui évoluent rapidement.

Ce que nous offrons :

  • Une excellente équipe et une culture stimulante.
  • Une carrière passionnante au sein d’une société de logiciels de renommée mondiale qui fournit des solutions pour l’architecture, l’ingénierie et la construction.
  • Un salaire et un ensemble d’avantages sociaux concurrentiels.
  • Un engagement envers l’inclusion, l’appartenance et le bien-être des collègues grâce à des initiatives mondiales et à des groupes de ressources.
  • Une entreprise engagée à faire une réelle différence en faisant progresser les infrastructures mondiales pour une meilleure qualité de vie, où vos contributions aident à bâtir un monde plus durable, connecté et résilient.
