Senior Mendix Front-End Consultant

First, what is low-code? Low-code is a visual approach to software development that enables you to abstract and automate every step of the application lifecycle. Gartner predicts that “by 2024, low-code application development will be responsible for more than 65% of application development activity.” Mendix is repeatedly ranked a Leader in analyst reports from Gartner and Forrester. In the 2021 Gartner® Magic Quadrant for Multiexperience Development Platforms, Mendix placed at the very top of the Leaders quadrant. 

 

Mendix, the global leader in enterprise low-code, was created to promote collaboration between Business & IT teams. Thousands of forward-thinking companies around the world like Ford Auto, Rabobank Netherlands, Zurich Insurance, and Red Bull, can unleash their best ideas faster with the help of the Mendix Platform.

The Role

 

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.

You’re the Innovator We Need If You Have:

• 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.
