AI Engineer [Middle]

Our AI Team is focused on two exciting goals: using AI tools to automate business processes across the company, and bringing AI solutions to everyone to boost productivity and spark interest in AI concepts among decision-makers.

We use AWS, Go, Python and cloud-based models, yet still flexible to mix ready-made tools and ship our custom solutions.

We're all about building systems that deliver real, valuable results for our organization. Our team has successfully pioneered a portfolio of AI solutions, including customer care chatbot, voice solutions, speech-to-text services, and an integrated HR automation ecosystem.

You will be a key specialist in a cross-functional team, working closely with backend and other LLM engineers.

Challenges that await you:

• Develop and manage AI/ML pipelines using Large Language Models. Your focus will be on model selection, configuration, creating robust wrappers, and designing the overall pipeline for data storage and retrieval

• Work with advanced prompts, set up RAG-oriented data sources for efficient retrieval, and evaluate model outputs to ensure accuracy, relevance, and quality

• Implement and refine advanced OCR solutions to automatically read, analyze, and validate business documents. This includes tasks such as identifying and extracting key entities, verifying their attributes, and ensuring data consistency across documents.

• Design and execute experiments and A/B tests to systematically compare the performance of different prompts, pipelines, and model configurations. You will use metrics to drive product decisions and continuous improvement cycles

• Work with the rest of the team to solve complex AI implementation challenges, review code, and ensure we deliver top-notch solutions.
