This team is responsible for developing AI-powered modernization pipelines that help migrate and evolve complex legacy applications, including scientific and engineering codebases, into modern cloud-native architectures.\nThis is a highly applied engineering role. You will work at the intersection of software engineering, AI systems, developer tooling, and modernization automation. Success is measured through production impact, scalability, reliability, and the ability to accelerate modernization across Bentley's portfolio of products.\nWhat You'll Do\nDesign and build AI-driven software transformation pipelines for large-scale legacy codebases.\nDevelop and improve agentic AI workflows that support code understanding, refactoring, validation, and modernization.\nModernize existing desktops, simulation, and engineering applications into cloud-native services and modern architectures.\nUse loop engineering approach to improve quality, reduce costs and accelerate the conversion/test/correction process.\nEvaluate and improve AI systems for accuracy, reliability, performance, observability, and cost efficiency.\nCreate automated tooling, validation frameworks, and testing strategies to ensure correctness of transformed code.\nPartner with architects, product leaders, and engineering teams to identify modernization opportunities and drive adoption.\nContribute to technical direction, best practices, and reusable modernization frameworks that can be leveraged across Bentley.\nHelp establish and share expertise in a rapidly evolving AI domain.\nThis role does not require travel.\nRequires sitting or standing at will while performing work on a computer (or any other physical requirements).\nRequired Qualifications\nStrong software development background with ownership of production systems.\nExperience building, maintaining, or modernizing complex software applications.\nDemonstrated understanding of software performance, reliability, scalability, testing, and failure modes.\nPractical experience applying AI, machine learning, inference pipelines, optimization techniques, or intelligent automation to real-world problems.\nSystems-oriented mindset with the ability to bring structure to ambiguous technical challenges.\nExperience designing pipelines, feedback loops, iterative systems, or large-scale developer tooling.\nStrong communication skills and the ability to collaborate with technical and non-technical stakeholders.\nPreferred Qualifications\nExperience with Rust, C++, C, or Fortran.\nExperience modernizing legacy systems or migrating applications to cloud-native architectures.\nBackground in DevOps, CI/CD pipelines, testing frameworks, simulation systems, benchmarking, or validation tooling.\nExperience working with engineering, scientific, mathematical, or simulation software.\nFamiliarity with cloud platforms and distributed systems.\nInterest in emerging AI development patterns, agentic workflows, and software transformation technologies.\nWhat Success Looks Like\nSuccessful candidates will demonstrate the ability to:\nModernize existing systems rather than only building greenfield solutions.\nMake thoughtful tradeoffs between performance, reliability, latency, maintainability, and cost.\nApply AI in practical, production-oriented ways.\nNavigate ambiguity while maintaining engineering rigor.\nBuild systems that continuously improve and scale over time.\nWho Thrives in This Role\nEngineers who enjoy applying AI to real-world engineering challenges and measuring success through production impact.\nBuilders who are comfortable working within large, evolving codebases.\nGeneralists who enjoy moving across languages, tools, and technical domains.\nEngineers who embrace continuous learning as AI capabilities and modernization approaches evolve.\n\nThis is a Hybrid role.\n\nWhat We Offer:\nStep into a collaborative work environment where ideas flourish, and teamwork propels us forward towards shared success.\nAn attractive salary and benefits package.\nBentley Impact Day: take a day off from work to volunteer with an organization of your choice.\nCelebrate milestone achievements and moments that matter through our colleague recognition award programs and our Bentley Achievers platform.\nA commitment to inclusion, belonging and colleague wellbeing through global initiatives and resource groups.\nBe part of a company committed to making a real difference by advancing the world’s infrastructure for better quality of life, where your contributions help build a more sustainable, connected, and resilient world.
