mendix technical lead.

developer and architect who will drive the technical success of our Mendix applications. This job
exists to provide deep Mendix platform knowledge and leadership in solution development. The Technical
Lead ensures that applications built on Client's Mendix platform are well-architected, meet business
requirements, and follow best practices for performance and maintainability.
We need this role to bridge business needs with the low-code technical implementation and solving complex
technical challenges on the platform. This role is essential to fully Through these responsibilities, the Technical Lead ensures each Mendix application is expertly crafted and
that the development teams are guided effectively, thereby delivering high-quality solutions quickly.

your tasks

Application Design & Architecture: Oversee the end-to-end technical design of applications built on Mendix. Work closely with business analysts, product owners and development teams to

understand functional requirements and solution architecture – including domain model (data

modeling), microflow design (business logic), page layouts (UI/UX), and integration interfaces 6 6.

Ensure the design aligns with Mendix best practices and meets scalability and maintainability criteria.

 

Integration of External Systems: Implement integrations between Mendix apps and external

services/databases. Use REST or SOAP connectors, OData services, JDBC/ODBC for direct

database connections, and leverage the Mendix App Store modules for specific integrations when possible. Handle data mapping and transformation within microflows to ensure seamless data exchange.

 

Code Reviews & Quality Assurance: Review the application models and configurations done by other Mendix developers at Client’s. Conduct thorough model reviews to ensure consistency with design principles, and that naming conventions, error handling, and logic are implemented correctly.

Use Mendix’s built-in Find errors and consistency checks to catch issues. Mentor the team by

providing constructive feedback and guidance on how to improve the solution.

 

Performance Tuning: Make sure all developments are being properly tested, analyzed and

optimized during development and testing phases.

 

Hands-on Development: More occasionally, the role holder might serve as a lead developer by

building key components of the application in Mendix Studio Pro. This may include creating entities, microflows, pages, navigation, and using Java actions or front-end custom code when necessary 1 .

The Technical Lead may also help on the development of the most technically challenging stories of some projects (e.g., implementing integrations with external systems or complex logic).

 

Testing & Validation: Establishing standard testing practices for Mendix apps and make sure there are properly conducted by development teams. Develop sample data and test cases to validate each component of the application. Automate tests when feasible (using Mendix ATS or Selenium for UI). Ensure that security tests (role-based access checks) are performed. The Technical Lead signs off that an application is technically sound and secure before it can be deployed to production.

 

Deployment Support: Although the Platform Owner manages the environments, the Technical Lead supports deployment by preparing release packages and environment-specific settings. The role owner uses the Mendix Developer Portal to transport applications between environments or resolve any issues that arise (like configuration differences or data initialization needed). After deployment, verify that the application is running as expected in the new environment (smoke testing).

 

Maintenance & Troubleshooting: Provide third level of support for Mendix applications after they go live. Checks with internal teams at Client's or with Mendix if the platform’s condition is identified as root cause.

 

Best Practice Champion: Act as the champion of Mendix development best practices and conventions. Create and maintain internal guidelines or a “playbook” for Mendix development for the team – covering things like module layering, usage of constants vs settings, error handling patterns, etc. Ensure that the team follows an agile methodology suited for low-code (frequent iterations, close feedback with users) and effectively uses Mendix collaboration features (stories, feedback management) to streamline development.

 

Mentoring and Leadership: Mentor junior Mendix developers by providing with hands-on coaching in using Mendix Studio Pro and Modeler. Organize peer programming or knowledge-sharing sessions to elevate the overall capability of the development team.

 

Continuous Improvement & Innovation: Keep abreast of new releases and features of the Mendix platform (such as product updates, new widgets, or AI-assisted development features). Evaluate how these can be leveraged in current or future projects. Similarly, look for opportunities to use the Mendix Marketplace components or share internally developed components for reuse across projects. The Mendix Technical Lead operates on both platform and application development contexts, making sure the platform is in perfect condition and applications are making the most of it from a technical standpoint.

Though this role does not have direct managerial authority over team members (unless the organization designates so), it wields technical leadership and influence.

 

Key context elements include:

Team Integration: The Technical Lead works closely with product owners, business analysts, UX

designers, and other developers from developing pods. The Technical Lead is often the go-to person for any technical question about how or what can be done in Mendix.

 

Project Scope: he handles multiple Mendix projects or modules at once, ensuring consistency,

reusability of component, and best practices across all these projects, effectively functioning as the global architect for Mendix solutions in our landscape.

 

Authority: In terms of technical decisions (e.g., how to implement a requirement in Mendix), the

Technical Lead has the final say, while aligning with enterprise architecture guidelines. For bigger

decisions affecting other systems (like introducing a new integration or data source), they

coordinate with the Platform Owner and enterprise architects.

 

Interdependencies: This role has a strong interdependency with the Mendix Platform Owner. The Technical Lead relies on the platform being available and efficient, and will coordinate on things like performance tuning (to distinguish if a slowdown is due to the app design or the infrastructure).

They also feed requirements to the Platform Owner, for instance, if an app needs a new

environment or if a certain monitoring metric would be useful. On the other side, the Platform

Owner might consult the Technical Lead when planning platform upgrades (to assess application

impact) or setting governance rules (to ensure they are realistic for developers).

 

Scope of Impact: The Technical Lead’s work directly impacts the success of individual Mendix

applications and, by extension, the business processes those apps support. Additionally, by

mentoring others, this role increases the capacity of the organization to deliver more Mendix apps

in parallel.

 

Challenges: The role must balance speed (one of the promises of low-code) with sound engineering. The Technical Lead often navigates trade-offs.

In essence, the Mendix Technical Lead’s context is that of a technical cornerstone in our low-code development efforts. This person ensures that rapid development does not come at the cost of quality or maintainability, and that the team is constantly learning and improving in the use of the Mendix platform.
