AI Engineer (LLM Implementation Specialist)

Job Summary:

We are seeking a freelance AI Engineer with expertise in adapting and implementing Large Language Models (LLMs) for specific projects, products, and tasks. This is a remote, short term position with an initial contract of 3 months and potential for extension. Applicants must be proficient in professional-level English and work from a time zone within 3 hours of Japan Standard Time (JST). While there is no plan or promise of long-term or permanent hiring, long-term opportunities may arise depending on performance and team fit. The client company is a Japan based Digital Marketing firm with serval Saas products already in the market.

Key Responsibilities:

●        Adapt pre-trained LLMs (e.g., GPT, BERT, etc.) to meet project-specific requirements.

●        Implement LLM-based solutions to optimize workflows, enhance products, or address domain-specific challenges.

●        Develop efficient pipelines for integrating LLMs into applications, APIs, or platforms.

●        Fine-tune LLMs with domain-specific datasets for improved contextual accuracy.

●        Design and test prompt engineering strategies to maximize model output relevance and quality.

●        Troubleshoot and resolve issues related to model behaviour, scalability, or integration.

●        Collaborate with cross-functional teams to ensure LLM solutions align with business objectives.

●        Document workflows, best practices, and outcomes for team learning and knowledge sharing.

Qualifications:

●        Bachelor’s or Master’s degree in Computer Science, Artificial Intelligence, or related field (or equivalent experience).

●        Strong understanding of LLM frameworks and APIs (e.g., OpenAI, Hugging Face Transformers).

●        Proficiency in Python and familiarity with deep learning libraries such as TensorFlow or PyTorch.

●        Experience fine-tuning pre-trained models and managing large-scale datasets.

●        Knowledge of prompt engineering techniques and strategies.

●        Strong problem-solving skills with a focus on practical, scalable solutions.

●        Professional-level English proficiency, both written and spoken.

Preferred Skills (Nice-to-Haves):

●        Familiarity with cloud-based environments for AI model deployment.

●        Experience applying LLMs to specific industry use cases (e.g., customer service, summarization).

●        Understanding of ethical considerations in LLM usage, including bias mitigation and data privacy.

●        Basic Japanese language skills (not required but advantageous for communication and documentation).

Work Conditions:

●        Employment Type: Ideally Freelance, full time preferred, part-time (50% capacity, ~20 hours per week is also possible).

1 year or more fixed contract employment also possible for the right candidate already located in Japan.

●        Contract Duration: Initial 3-month contract, with potential for extension based on project needs and performance.

●        Location: Remote, with a time zone compatible with Japan Standard Time (JST) within 3 hours.

●        Wages: To be discussed and determined based on qualifications and project scope.

●        Smoking Policy: This position is remote; therefore, applicants should comply with the local smoking regulations of their country of residence.

Why Join Us?

●        Work with a dynamic & international team on innovative AI projects applying state-of-the-art LLM technology.
