Your tasks

We are looking for a Machine Learning Engineer to join our growing ML team and strengthen our Conversational AI Squad — a group dedicated to creating Agentic AI use-cases that unlock the full potential of the DiliTrust suite through advanced, intelligent conversational interfaces.

In this role, you will work at the intersection of applied research and production-grade engineering - designing, developing, and deploying scalable ML systems that power real-world features.

You will collaborate closely with data scientists, backend engineers, and product managers to bring generative AI capabilities into our core products.

You'll contribute across two main areas:

1 - Advance Our Internal AI Capabilities

• Conduct applied research to push our internal state-of-the-art in generative and semantic AI.
• Design and maintain fine-tuning pipelines for LLMs, leveraging RLHF, GRPO, and domain-specific optimization techniques.
• Develop robust, reusable components and pipelines for experimentation, training, evaluation, and deployment.

2 - Design & Implement Agentic AI Use-Cases

• Collaborate with product and engineering teams to conceive, prototype, and deploy AI agents that deliver tangible value across product modules (e.g., contract analysis, board meeting preparation, cross-module reporting).
• Implement scalable model serving and deployment strategies for production environments.
• Benchmark, monitor, and iteratively improve agent performance through systematic evaluation.

What we are looking for

• Proven experience with LLM fine-tuning and prompt engineering for production use cases.
• Strong background in NLP, RLHF, or model optimization techniques.
• Skilled in building and maintaining ML pipelines in Python with modern frameworks (e.g., vLLM, Autogen, LangChain, ADK).
• Familiarity with CI/CD, MLOps best practices, and testing strategies for ML systems.

Our technical stack

• LLM Frameworks & Agent Tooling: vLLM, LangChain, Autogen, ADK
• Model Development & Fine-Tuning: PyTorch, Hugging Face Transformers, RLHF, GRPO, domain-specific optimization pipelines
• Experimentation & Tracking: MLflow, Tensorboard, Grafana
• MLOps & Deployment: Model serving with vLLM, torchserve and FastAPI, CI/CD for ML containerized workflows with Docker, orchestration via Kubernetes / CloudRun
• Infrastructure & Cloud: GCP, OVH
