About the role

As a LLM Engineer you will be in charge of selecting and refining the ML models and interactions for our AI-powered assistant. You will design, develop, and optimize Promt (Prompt + Model) systems that facilitate natural and interactive human-AI interactions and focus on enhancing the quality, coherence, and relevance of AI-generated prompts and responses, ensuring that AI systems can understand user input, generate contextually appropriate outputs, and effectively engage in dynamic conversations.

Minimum qualifications

  • Bachelor's in Computer Science, Engineering, or related field.
  • 1-2 years of industry experience in natural language processing, dialogue systems, or related fields.
  • Proficiency with our core ML and LLM tech stack: Python ecosystem, Embeddings, Pytorch, Huggingface, Langchain, AWS (SageMaker, etc.) and text2SQL.
  • Strong understanding of language modeling, text generation, and machine learning techniques.
  • Experience with neural network architectures for NLP tasks, such as transformers, recurrent neural networks (RNNs), and sequence-to-sequence models.
  • Familiarity with dialogue management, context modeling, and conversational AI principles.
  • Hands-on experience with fine-tuning and optimization of pre-trained language models.

Preferred qualifications

  • Experience in the payments, banking or accounting sector is a huge plus
  • Experience with deploying AI systems into production environments.
  • Familiarity with cloud platforms (AWS) and containerization technologies.
  • Knowledge of reinforcement learning techniques for dialogue systems.

  • Collaborate with cross-functional teams to identify, design, and implement innovative ML solutions for real-time navigation and user interaction.
  • Work on using LLMs and tools like LangChain to build agent-based workflows.
  • Developing algorithms and strategies for generating and managing AI prompts and responses within a conversational context.
  • Researching, experimenting with, and iterating on techniques to improve the performance of Promt systems in terms of understanding user intent and generating coherent and relevant responses.
  • Fine-tuning language models to ensure alignment with user context and intent.
  • Developing methods for context-aware language generation, considering previous interactions and maintaining coherent conversations.
  • Implementing advanced neural network architectures, such as transformers, recurrent neural networks (RNNs), and sequence-to-sequence models, to improve language generation.
  • Participate in code reviews and provide mentorship to team members, fostering a culture of knowledge-sharing and continuous learning.


  • Well-funded and proven startup with large ambitions and competitive salaries.
  • Entrepreneurial culture where pushing limits, creating and collaborating is everyday business.
