Indexed description

Alpha CRC is a dynamic translation and language services group, operating across multiple geographies and serving a diverse client base. With several businesses under our umbrella and offices in key global markets, we pride ourselves on delivering high-quality, culturally nuanced language solutions. We are looking for a skilled AI Engineer to design, build, and deploy AI-powered systems that enhance our products and operations. This role combines software engineering, machine learning, and practical problem-solving. You will work across the full lifecycle of AI development—from model integration and prompt optimization to pipeline deployment and monitoring. You will maintain high-quality code and evaluate the performance of the systems you develop.


Tasks

  • Implement multi-agent architectures using frameworks such as CrewAI to orchestrate complex AI tasks and workflows

  • Fine-tune transformer models using techniques such as LoRA, PEFT, or supervised fine-tuning to improve performance on domain-specific tasks

  • Evaluate model performance, run experiments, and optimize for accuracy, latency, and reliability.

  • Design and implement endtoend AI pipelines (data ingestion, feature engineering, inference).

  • Collaborate with cross-functional teams to define requirements and deliver AI solutions that meet business goals.

  • Implement retrieval-augmented generation (RAG), prompt engineering, or agent-based architectures as appropriate.

  • Maintain high-quality code through testing, documentation, and best practices.

  • Monitor and troubleshoot production AI systems, ensuring high availability.

  • Stay current with new AI frameworks, models, and tooling.
