[Hiring] Senior Mendix Front-End Consultant @Mendix

Role Description

Mendix is on a mission to enable anyone in any organization — from the marketing coordinator to the software developer to the CEO — to create things that are transformational for their company. We are fundamentally reinventing the way applications are created, and we need innovators like you to help lead the charge.

As a Frontend Developer on our Expert Services team, you’ll be the lead frontend developer on engagements with our customers — guiding them toward best-in-class UI experiences while serving as a trusted technical advisor throughout delivery. You’re someone who can challenge assumptions, pave the path for best practices, and make confident visual decisions when no designer is in the room.

You’ll Drive Digital Innovation By:

• Acting as the lead frontend developer on Expert Services engagements with Mendix customers, owning delivery quality and scalability.
• Advising and guiding customers in maximizing the user interface of their Mendix applications, enabling them to become self-sufficient on the platform.
• Developing reusable UI elements using CSS, SASS, HTML5, and React, leveraging the Mendix Atlas UI Framework across Responsive, PWA, and Native contexts.
• Making autonomous, informed visual and UX decisions on projects without dedicated design resources — ensuring applications remain polished, consistent, and user-centered.
• Translating business requirements directly into intuitive UI designs, owning the full journey from concept to implementation.
• Establishing and maintaining visual consistency across applications through self-directed application of design systems, typography, spacing, and color theory.
• Facilitating project meetings and Scrum ceremonies, championing Scrum methodologies with customer stakeholders.
• Contributing to internal documentation, UI patterns, and best practice sharing within the Expert Services team.
• Building your project portfolio and brand within the Mendix developer community by creating and sharing valuable frontend content.

Qualifications

• 4+ years of experience in frontend development and/or consulting and app delivery.
• Proficiency in CSS, SASS, HTML5, and React; React Native experience is a strong plus.
• A demonstrable design eye — the ability to make autonomous aesthetic and UX decisions that meet professional design standards without explicit designer guidance.
• A portfolio that showcases not just technical implementation but thoughtful, visually refined UI work. (Required as part of your application.)
• Familiarity with design tools such as Figma, with the ability to create wireframes or mockups independently when needed.
• Working knowledge of accessibility standards (WCAG) and responsive design principles to ensure quality outcomes regardless of project team composition.
• Experience developing mobile-friendly, responsive web applications.
• Mendix Advanced Certification (or willingness to obtain).
• Proven ability to build trusted client relationships and navigate complex project dynamics.
• Relevant degree in Computer Science or a related field.

Requirements

• $125,000 - $200,000 a year
• Total Comp 80/20 split
