Purpose of this Position
The Senior Solution Architect is responsible for designing and guiding enterprise solutions that bring together Mendix applications, connected enterprise data, AI capabilities, knowledge graphs, integrations and intelligent workflows.
This role serves as the technical leader for complex client engagements and establishes VeilSun's capabilities across the Siemens and Altair platform stack: Mendix, Graph Studio (formerly Altair Graph Studio and Anzo) and AI Studio (formerly Altair RapidMiner). The position requires someone who can move from business problem to technical architecture, determine how the three layers of the platform should work together, build the first versions personally, and provide hands-on guidance to the teams implementing those solutions.
This person will work closely with clients, project teams, developers and practice leadership to ensure solutions are practical, scalable, secure, maintainable and aligned with business outcomes.
Business Outcomes
Success in this role means VeilSun can confidently design and deliver enterprise AI and knowledge graph solutions, technical teams have clear architectural direction, and clients receive solutions that effectively connect applications, enterprise data, AI and business processes.
You will be measured on:
Successful architecture and delivery of Mendix, Graph Studio and AI Studio solutions
Quality, scalability, security and maintainability of solution designs
Ability to translate complex business problems into clear technical approaches
Effectiveness of technical leadership provided to project teams
Growth of VeilSun's internal enterprise AI and knowledge graph expertise, standards, reusable patterns and delivery capabilities
Ability to identify appropriate uses of AI, agents, knowledge graphs, workflow automation and traditional application logic
Successful collaboration with clients, developers, project managers and other technical stakeholders
Contribution to discovery, solutioning, estimation and presales activities
Core Responsibilities
Lead technical discovery and solution architecture for Mendix, enterprise AI and knowledge graph engagements
Translate client objectives, business processes, data and system constraints into scalable technical solutions
Personally build the first Graph Studio models and AI Studio pipelines on early engagements, then turn them into patterns the team can repeat
Build knowledge graphs in Graph Studio: onboard data from ERP, PLM and SQL sources, design or extend ontologies, write SPARQL, deploy and tune
Build and deploy machine learning pipelines and AI agents in AI Studio, AI Hub and Agent Builder, with guardrails and governance
Determine how application logic, workflow automation, AI agents, machine learning and human decision making should work together within a solution
Design secure and maintainable integration patterns using APIs, events, middleware and other enterprise integration approaches
Provide architectural direction throughout the full delivery lifecycle, including discovery, design, implementation, deployment and support
Work directly with developers to review implementations, resolve complex technical issues and reinforce development and architecture standards
Ensure appropriate consideration of security, identity, permissions, governance, observability, performance and scalability
Partner with project managers and client stakeholders to identify technical risks, dependencies, assumptions and tradeoffs
Support estimates, technical solutioning, proposals and presales conversations for enterprise AI, knowledge graph and Mendix opportunities
Establish reusable patterns, reference architectures, standards and best practices for Mendix, Graph Studio and AI Studio delivery
Mentor Mendix developers and other technical team members as VeilSun expands its enterprise AI and knowledge graph capabilities
Stay current with changes across the Mendix, Siemens and Altair ecosystems, including Graph Studio and AI Studio, and help determine when new capabilities should be adopted
Decision Authority
You have authority to:
Define and recommend the technical architecture for assigned Mendix, Graph Studio and AI Studio solutions
Determine appropriate architectural patterns, integration approaches and technology usage within established project and organizational constraints
Recommend whether a business capability should be implemented using traditional application logic, workflow automation, AI, machine learning, agentic capabilities or a combination of approaches
Establish technical standards and implementation guidance for project teams
Require remediation of architectural, security, scalability or maintainability concerns that create meaningful delivery or client risk
Escalate technical risks, dependencies or scope concerns that may impact successful delivery
Recommend reusable components, reference architectures, tools and patterns for broader practice adoption
Provide technical input into project estimates, staffing needs, delivery approaches and solution feasibility
Desired Behaviors and Attributes
Thinks in terms of the complete business and technical system rather than a single application or technology
Is comfortable working through ambiguity and turning loosely defined business problems into clear technical approaches
Balances technical sophistication with practical delivery needs and avoids unnecessary complexity
Can communicate complex technical concepts clearly to developers, business stakeholders and client leadership
Stays hands-on: builds, validates technical decisions and helps teams through difficult implementation challenges
Approaches AI pragmatically and understands that AI is not the right solution for every problem
Considers security, governance, maintainability, supportability and long-term ownership as part of architecture decisions
Coaches and develops others rather than becoming a bottleneck for technical decisions
Proactively identifies risks, assumptions, dependencies and areas where additional discovery is required
Continuously learns as the Mendix, Siemens, Altair, enterprise AI and knowledge graph ecosystems evolve
Failure Patterns We Avoid
Treating enterprise AI and knowledge graph work as simply another Mendix development project
Defaulting to AI or agentic solutions where straightforward application logic or workflow would be more reliable
Designing technically impressive solutions that are unnecessarily difficult to build, support or maintain
Building AI capabilities without sufficient attention to security, data access, governance, auditability or human oversight
Creating knowledge graphs or semantic models without a clear business purpose
Making architecture decisions without considering existing enterprise systems, integration constraints or client capabilities
Designing in isolation without involving the developers and teams responsible for implementing and supporting the solution
Allowing architectural standards to become theoretical documentation that does not influence actual implementation
Becoming a required approval point for every technical decision instead of enabling teams to operate independently
Overcommitting to unfamiliar platform capabilities without validating feasibility, effort or delivery risk
Required Qualifications
Hands-on project experience with at least two of Graph Studio (Altair Graph Studio or Anzo), AI Studio or Altair RapidMiner, and Agent Builder, or completed Siemens partner enablement on these platforms with a build to show for it
Knowledge graph fund
