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. Requirements Qualifications Required * Bachelor’s degree in Computer Science, Engineering, Data Science, or a related field (or equivalent experience) * 3+ years of professional software development experience * Strong Python programming skills * Hands-on experience with machine learning frameworks: PyTorch, TensorFlow, Scikitlearn * Experience working with LLMs, embedding models, or AI APIs (OpenAI, Azure OpenAI, HuggingFace, etc.) * Knowledge of building and consuming APIs (REST, GraphQL) * Experience with version control (Git) and modern development workflows * Strong problemsolving and communication skills Preferred * Experience fine-tuning large language models using HuggingFace or similar frameworks * Experience running local models with Ollama or similar inference platforms * Experience with RAG pipelines and vector databases (Pinecone, FAISS, Chroma) * Background in NLP, computer vision, or deep learning * Experience optimizing models for performance or cost (quantization, distillation) Benefits * Hybrid working options * Access to cutting-edge AI technologies and cloud environments * Opportunities to shape AI strategy and build impactful solutions * A supportive, collaborative, and innovation-driven culture Please submit your CV and a short statement of interest. Applications will be reviewed on a rolling basis.
