Mendix Developer Jobs (NOW HIRING)

Presales Solution Architect - Mendix Private Platform (Specialist) 

About the Role 

We are looking for a specialist Presales Solution Architect to help organizations adopt Mendix low-code development on Private Mendix Platform - Mendix's fully self-managed platform for customers who need to run the complete development and deployment lifecycle inside their own Kubernetes or OpenShift environment, including air-gapped and sovereign deployments. 

This role sits at the intersection of application platform and infrastructure. You will partner with prospects, customers, sales teams, and partners in regulated and security-conscious industries - government, defense, financial services, healthcare, and critical infrastructure - to demonstrate how Mendix and Private Mendix Platform deliver rapid application development without compromising on data residency, compliance, or operational control. You will lead technical discovery, architect deployment topologies, build proof-of-concepts, and act as a trusted advisor throughout the customer journey. 

What You'll Do 

Solution Architecture & Customer Engagement 

• Lead technical discovery sessions to understand customer challenges, infrastructure constraints, security requirements, and modernization initiatives. 

• Design end-to-end solution and deployment architectures for Private Mendix Platform on customer-managed Kubernetes or OpenShift - including cluster topology, PostgreSQL databases, file storage, container registries, ingress/TLS, and namespace strategy. 

• Guide customers through security and compliance conversations: FIPS-compliant encryption, secret management (AWS Secrets Manager, Azure Key Vault, HashiCorp Vault), SSO/IdP integration (OIDC and SAML), and control frameworks such as NIST 800-53. 

• Conduct technical workshops, architecture sessions, and executive briefings; serve as a trusted advisor throughout the sales cycle. 

Demonstrations & Proof of Concepts 

• Deliver compelling business and technical demonstrations of Mendix application development and the Private Mendix Platform portal - project management, private Marketplace, CI/CD, and governance capabilities. 

• Stand up proof-of-concept and pilot environments: install and configure the Mendix Operator, Private Cloud License Manager (PCLM), and optional components such as webhooks (Svix), the Build agent, PDF document generation, and Maia AI-assisted app creation. 

• Build prototype Mendix applications that showcase integration with enterprise systems, APIs, and databases inside the customer's environment. 

• Demonstrate best practices for application governance, scalability, security, and lifecycle management in self-managed deployments. 

Platform Adoption & Enablement 

• Help customers plan the operational side of ownership: platform upgrades, component management, licensing via PCLM, backup and environment strategies. 

• Position the roadmap from disconnected (air-gapped) to Connected mode deployments where appropriate. 

• Enable partners and customer platform teams on installation, configuration, and day-2 operations. 

Sales & Field Partnership 

• Partner with Account Executives on opportunity strategy, technical qualification, and deal progression. 

• Respond to RFPs, RFIs, and security/technical questionnaires - often deep infrastructure and compliance-focused. 

• Support marketing events, webinars, conferences, and partner enablement sessions. 

• Share field learnings with product and engineering teams to influence roadmap priorities. 

What You'll Bring 

• 5+ years of experience in presales, solution architecture, platform engineering, or technical consulting in a customer-facing role. 

• Hands-on experience with Kubernetes and/or OpenShift: deployments, Helm, operators, ingress, storage, registries, and troubleshooting with kubectl. 

• Working knowledge of the surrounding enterprise stack: PostgreSQL, object/file storage (S3, Azure Blob), container registries, TLS/certificates, and networking. 

• Ability to lead security and compliance conversations with infrastructure, security, and platform teams as comfortably as with business stakeholders. 

• Excellent communication and storytelling skills - able to translate deep technical capability into business value for practitioner and executive audiences. 

• Ability to independently build and deliver demos, installs, and prototypes under deal timelines. 

• Willingness to travel up to 30% within the United States. 

• [Work authorization / clearance requirements - note: if this role serves defense or federal customers, specify citizenship or clearance eligibility here.] 

Preferred Qualifications 

• Experience with Mendix application development, architecture, or consulting - ideally including Mendix on Kubernetes or Private Mendix Platform deployments. 

• Experience deploying software in air-gapped, sovereign, or highly restricted network environments. 

• Familiarity with enterprise secret management (AWS Secrets Manager, Azure Key Vault, HashiCorp Vault) and IdP integration (OIDC, SAML, SCIM). 

• Experience selling into or delivering for regulated industries (government, defense, financial services, healthcare). 

• Familiarity with compliance frameworks such as NIST 800-53, FedRAMP, or FIPS 140 requirements. 

• Knowledge of CI/CD tooling and Git-based version control workflows in enterprise settings. 

Bonus Points If You 

• Are already a certified Mendix Developer, Advanced Developer, or Expert. 

• Have installed or operated Private Mendix Platform, the Mendix Operator, or Mendix on Kubernetes in a customer or enterprise environment. 

• Have built customer-facing demo environments or reference architectures for self-hosted platforms. 

• Enjoy working where application development meets infrastructure - and can move fluently between Studio Pro and a kubeconfig.
