Arionkoder is an AI consulting firm helping companies build, embed, and own AI systems that drive real business outcomes. We combine Product Development, Artificial Intelligence, and Team Augmentation to craft digital products and solutions that create lasting impact — guided by a human-centric approach and a commitment to pushing the boundaries of what technology can do. We're hiring a Software Architect to own the end-to-end design of a complex software product. The role spans the full architectural surface (data, services, integrations, infrastructure, security, reliability) and sits at the intersection of engineering, product, and the customer environments the product runs inside. The right person treats constraints like multi-tenancy, legacy interoperability, cost, and regulatory exposure as first-class design inputs, not afterthoughts. This is a hands-on architect role, not a diagrams-and-handoffs role. You're equally comfortable working in the abstract (RFCs, system models, trade-off analysis) and in the concrete (debugging a memory leak, profiling a hot path,



rewriting an integration that's silently drifting). You're comfortable in ambiguity. You can join a product mid-flight, form a sharp view of what's load-bearing and what's incidental, and propose a direction the team can rally behind. You treat AI-augmented engineering as a force multiplier you wield with judgment, neither a gimmick nor a substitute for thinking.
