• Strong programming skills in Python (Go or Java also welcome) with solid software engineering fundamentals.
• Strong analytical and problem-solving skills with good engineering judgement.
• Excellent communication skills - able to work with stakeholders to understand automation needs.
• Bachelor's degree in Computer Science or a related field; equivalent hands-on experience considered.

Nice to have

• Experience with at least one major cloud platform (AWS, GCP, or Azure) and containerisation (Docker).
• Experience integrating large language models and foundation models into products: fine-tuning, RAG, prompt engineering.
• Experience shipping language-model features (chat assistants, agents, copilots) to real users.
• Contributions to open-source projects or published technical writing.
