Solutions Engineer (Core AI)

Mendix, a Siemens business, powers hybrid agentic workforces by enabling organizations to build, scale and orchestrate agents and applications faster by combining low-code, AI, data, and integrations into a unified platform. The Technical Solutions Marketing team builds technical credibility for Mendix through validated architectures, reusable proof points, and real-world implementations. In this role, you will work directly with customers and the field to prove high-value use cases through lighthouse implementations, then package what works into reusable patterns, components, and technical narratives that scale across GTM and delivery ecosystems.

Responsibilities

Design and implement customer-facing prototypes and lighthouse implementations to validate high-value AI and integration use cases; Lead strategic workshops and technical deep dives with customers and field teams, especially for agentic AI workflows and complex integrations; Turn validated customer work into reusable assets: reference architectures, blueprints, accelerators, and repeatable patterns; Serve as the deep technical owner for agentic system design, including tool use, orchestration, and multi-agent patterns; Design and maintain complex integration architectures across enterprise platforms and data systems; Ground GTM positioning and storytelling in validated technical proof points, supporting high-impact moments like executive demos and analyst briefings.

Requirements

Demonstrable, hands-on experience designing and building agentic AI systems in production-realistic environments (tool use/function calling, orchestration/planning, multi-agent patterns where appropriate); Strong practical knowledge of LLM application architecture, including retrieval (RAG), grounding, prompt/system design, and structured outputs; Experience implementing evaluation and reliability loops (test harnesses, offline/online evals, monitoring, feedback, iteration) and guardrails (safety, policy, data controls); Proven ability to integrate agentic workflows with enterprise systems and data (APIs, events, identity, governance) and to design complex integration architectures; Strong background in system architecture and end-to-end solution delivery (security, scalability, reliability, observability, deployment readiness); Experience with enterprise platforms and ecosystems (Siemens stack a plus), data platforms, and modern AI tooling; Ability to translate complex technical capabilities into reusable patterns, reference architectures, and clear technical narratives for GTM and customer contexts; Strong communication and collaboration skills across Product, GTM, engineering, and customer stakeholders.
