Expert Mendix Developer

The Expert Mendix Developer is a senior, hands-on technical role responsible for the design, build, and long-term health of AIO Logic's Mendix applications, including AXIS, our AI-powered loan origination, servicing, and management platform. This person translates complex commercial lending business logic into scalable Mendix microflows, domain models, and UI components; extends the platform through custom Java actions, widgets, and integrations; and leads architectural decisions that keep the codebase clean, secure, and maintainable as AIO Logic scales. The role also carries a mentorship mandate, raising the bar for design, modularization, and coding standards across the development team.

AIO Logic is scaling its Mendix-based platform across banks, private credit funds, and specialty finance institutions that depend on it to run core lending operations. This role exists to ensure that growth doesn't come at the cost of quality — pairing deep Mendix expertise with financial services domain knowledge so the platform stays performant, secure, and architecturally sound while the team building it grows around consistent standards and mentorship.
