The Role
Etraveli Group is scaling agentic AI across software engineering, finance, sales analytics and beyond. To support this we are looking for an AI Solutions Engineer to serve as a primary technical point-of-contact for our AI initiatives.
Together with AI Business Analysis that will identify what we should build, you are responsible for the How. You will both support prototyping and transforming concepts into robust, scalable and production-ready AI systems. Hence, you will bridge the gap between rapid PoCs and core engineering, ensuring all components are reliable, secure and deeply integrated into our tech ecosystem. You will also work closely with Data and Machine Learning Engineers, Product Managers, and business stakeholders across the organisation.
This is not a purely technical role. The right person can understand the underlying business needs and answer questions on feasibility and delivering value by selecting the latest AI technologies, agentic frameworks and orchestration patterns that don’t just conceptually look good, but actually solve high-stakes complexities within Etraveli.

Technical Consulting & Advocacy
Stay on top of latest LLM and agentic AI developments and bring relevant capabilities to the attention of the team
Lead technical evaluations of new frameworks with regard to their potential of enabling new initiatives
Act as the technical subject matter expert for AI within the tech organization supporting the organisation's transition to working with LLMs and agentic AI tools – helping teams move from curiosity to confident, productive use
Requirements
3–5 years with a solid foundation as a Machine Learning Engineer or Backend Engineer focused on ML systems
Understanding of core architectural components in modern AI systems
Proficiency in Python with the ability to build scalable high performance services and integrated complex ML and AI logic into production environments
Proven experience in deploying open source LLMs on on-prem infrastructure or building using external LLMs
Strong understanding of RAG, vector databases and the infrastructure required to support data-heavy AI applications
Exposure to concepts like CI/CD and Orchestration and a basic understanding about service monitoring and alarms as well as secrets management
Nice to have
Hands-on experience with agentic frameworks like LangChain to build autonomous, multi-step reasoning workflows
Familiarity with modern data stacks (SQL, Spark, Dremio) and the ability to collaborate and put requirements on data pipelines that feed AI solutions
Previous experience with NLP prior to the LLM era
Experience deploying ML workloads using Kubernetes and Docker
Exposure to data privacy in LLM workflows and an awareness of common vulnerabilities like jailbreak attacks and prompt injection
