Jobbeschreibung

For the NXTminds freelance talent pool, we are looking for experienced Senior AI Engineers with a proven track record in designing, building and implementing AI agent solutions within complex organisations.

You are a hands-on engineer with deep technical expertise. You have independently developed, or taken technical ownership of, AI agents that are successfully running in production and actively being used. You oversee the entire technical lifecycle, from architecture and development to integration, deployment and optimisation.

You are also a confident sparring partner for senior stakeholders. You understand the business context, make well-founded technical decisions and know how to successfully implement AI solutions within existing IT environments.

Through NXTminds, you will be considered for challenging freelance assignments with organisations looking to embed AI into their business processes and services.

Practical Information

• Contract type: Freelance / independent contractor (no temp-to-perm arrangements or payroll contracts)
• Location: Must be residing in the Netherlands (mandatory requirement)
• Seniority: Senior level, with demonstrable experience delivering AI solutions into production within enterprise environments

About the organisation

NXTminds connects experienced independent AI specialists with corporates, large family-owned businesses and (semi-)public organisations. Our clients seek professionals who go beyond experimentation and can successfully develop, implement and scale AI solutions within complex enterprise environments.

Assignments focus on challenging AI initiatives where technical expertise, security, integration with existing systems and senior stakeholder management come together.

Through NXTminds, you gain access to challenging freelance opportunities with organisations pursuing ambitious AI strategies. We offer complex enterprise projects where your technical expertise makes a tangible difference, access to an extensive network of clients seeking senior AI specialists, and personal engagement to match assignments with your expertise, availability and preferences.

All while maintaining the independence and flexibility that experienced freelance professionals value.

What are you going to do?

• Design and build AI agents: Develop robust agentic AI systems for complex business processes and workflows.
• Deliver end-to-end implementations: Take solutions from architecture and development through to production, including integrations with enterprise systems, APIs and data sources.
• Make technical decisions: Take ownership of architecture, LLM selection, agent orchestration, security and scalability.
• Ensure production-grade quality: Deliver reliable applications through testing, monitoring, evaluations, guardrails and CI/CD.
• Advise senior stakeholders: Independently engage with IT management, enterprise architects and business owners on technical opportunities, risks and business value.

We are looking for:

• Proven production experience: You have personally designed and built AI agents, or led their technical implementation, that are actively used within a larger organisation. You can clearly explain your individual contribution and the measurable impact achieved.
• Strong software engineering foundation: Excellent Python skills and extensive experience with software architecture, APIs, system integrations and cloud platforms such as Azure, AWS or GCP.
• Deep AI agent expertise: Hands‑on experience with LLM integrations, tool/function calling, agent orchestration and frameworks such as LangGraph, Semantic Kernel or AutoGen.
• Enterprise‑grade engineering: Experience with RAG, vector databases, security, testing, monitoring, CI/CD and the reliable deployment and management of AI solutions.
• Senior stakeholder management: You independently advise technical and business decision‑makers, clearly substantiate complex technical decisions and provide direction.
• Ownership: You work independently, take technical responsibility and drive complex initiatives from concept to fully operational solutions.
• Freelance status and location: You operate as an independent contractor and reside in the Netherlands.
• Language skills: Fluency in Dutch is a strong advantage. Fluency in English, both written and spoken, is required.

Important: demonstrable experience is essential

This talent pool is exclusively intended for experienced engineers with proven hands‑on experience delivering AI agents into production.

Experience limited to personal AI experiments, proofs of concept or participation in AI projects without substantial individual technical responsibility is not sufficient.

We are looking for engineers who can confidently demonstrate: I built this myself, it is running in production, it is actively being used, and this was my specific contribution.

This is how the process works when responding to a job as NXTmind
