People who believe success means growing together, learning from each other, and challenging the status quo.\nIf that sounds like you, keep reading.\nAs Application Architect you will be part of our Architecture team, with a specific focus on one of our domains: the Verified Data application landscape.\nYou’ll contribute to solution designs that meet both business and technical objectives, ensuring alignment with Isabel’s long-term vision. In addition to contributing to design and review activities, you’ll actively promote architecture documentation as code, using the C4 model to describe software systems at multiple levels of abstraction. This ensures that documentation remains accurate, version-controlled, and aligned with the development lifecycle, while fostering transparency and knowledge sharing across teams.\nWhat you’ll do\nEngage actively with all relevant parties to gather comprehensive requirements - encompassing user, technical, and performance specifications - and synthesize these into unified solution designs.\n\nChampion your architectural proposals, striving to achieve excellence in fulfilling stakeholder needs and maximizing the value of project outcomes.\n\nTake the helm during the project's initiation phase and provide ongoing leadership and expertise to the delivery teams throughout the execution phase, serving as the project's architectural lead when necessary.\n\nEnsure that the proposed solutions are aligned with the overarching technology strategy and comply with corporate governance standards.\n\nCultivate a practice of thorough documentation, guaranteeing that it is a true and clear reflection of active operations and is readily understandable and available to stakeholders.\n\nStay abreast of technology trends to drive innovation and continuous improvement within the application domain.\n\nPropose architectural patterns, assess modularity and dependencies, and identify improvement areas - without participating in hands-on development.\n\nUnderstand and deconstruct legacy and modern systems to inform design decisions, guide modernization efforts, and propose architecture roadmaps.\n\nRequirements\nWhat makes you a great fit\nThis role is ideal for someone who can analyze and understand complex, large-scale applications independently - not to develop them, but to extract architectural insights, assess design quality, and support strategic evolution of our application ecosystem.\nYou’ll thrive in this role if you:\nhave experience in architectural design patterns, microservices architecture, and creating system architectures that are scalable, resilient, and aligned with business needs.\n\nare able to identify, quantify, and strategize the reduction of technical debt.\n\nhave a track record in reliability engineering & performance optimization.\n\nhave an understanding of security best practices (you’ll be supported by a Security Architect).\n\nhave an understanding of cloud computing platforms, infrastructure as code, containerization, and orchestration technologies (you’ll be supported by a Infrastructure Architect).\n\nCapable of analyzing how data storage, access, and integration are handled in enterprise systems, particularly in high-availability financial environments.\n\ncan effectively communicate complex technical concepts to non-technical people and work with various departments to understand their needs and constraints.\n\nhave the ability to adapt to and work with various development and project management methodologies.\n\nare able to explore and understand unfamiliar, complex systems with minimal guidance, especially through source code and system documentation.\n\nAre fluent in English (knowledge of Dutch and/or French are a strong plus).\n\nWhy join us\nAt Isabel, we offer more than a job, we offer a place to grow, contribute, and thrive.\nA human-sized Belgian company (250 people) where your ideas and impact matter\n\n50% hybrid work, flexible hours, and autonomy to manage your time\n\nCoaching, training, and tailored development paths for every career stage\n\nA flat, collaborative structure with real ownership and cross-functional work\n\nCompetitive rewards: Flex Income Plan, annual bonus, insurance, meal vouchers\n\nA strong engagement culture and inclusive mindset\n\nEasy mobility options: our MOBI strategy supports flexible, low-footprint commuting, whether by bike, public transport, or electric car\n\nProfessional gatherings that encourage collaboration and networking, as well as fun and purposeful activities led by our BeFun team\n\nA certified Top Employer with 30 years of tech leadership and ambition\n\nReady to join us?\nYour voice, your vision, and your impact all have a place here.\nLet’s shape smarter solutions and a stronger digital economy.
