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 fundamentals: RDF, OWL and SPARQL, with SHACL a plus
• Mendix Intermediate Developer certification or higher with at least one Mendix application shipped, and Advanced certification within 90 days of hire
• Significant experience designing and delivering enterprise software solutions, including leading technical discovery and solution architecture for complex projects
• US person, able to pass client background checks, working US time zones
• Ability to travel up to 20% for client workshops and onsite engagements

Preferred Capabilities

• Mendix Advanced or Expert Developer certification, including application design, domain modeling, integrations, security, deployment and performance
• Experience integrating applications with multiple enterprise systems through REST APIs, OData, events, middleware or similar technologies
• Experience with RDF graph platforms such as Stardog, Ontotext GraphDB or Amazon Neptune. Property graph experience (Neo4j, TigerGraph, Cypher, Gremlin) is useful background but not a substitute for RDF and SPARQL
• Understanding of modern AI concepts including large language models, retrieval-augmented generation, AI agents, context engineering, tool use and human-in-the-loop workflows
• Experience designing or implementing enterprise generative AI, RAG, machine learning or agentic AI solutions, with Python scripting inside pipelines
• Understanding of cloud architecture, identity and access management, application security, observability and enterprise deployment patterns
• Experience with Siemens technologies such as Teamcenter, Opcenter, NX, Polarion or Insights Hub
• Experience with Snowflake, Databricks or similar data platforms
• Experience in manufacturing, energy and utilities, transportation, engineering, aerospace and defense, life sciences or other complex enterprise environments
• Familiarity with concepts such as PLM, MES, digital thread, digital twin, BOM, engineering change management, manufacturing quality or asset lifecycle management
• Experience mentoring developers or providing technical leadership across delivery teams

The annual base salary range for this position is $160,000–$190,000, depending on experience.
