AI Prompt Engineer

Are you a Prompt Engineer who’s just as comfortable shipping production-grade LLM pipelines as crafting the perfect prompt? Join us in building AI systems that don’t just sit in a notebook, but actively power teams across Malta and Europe.

We’re looking for someone with hands-on experience in:

• Prompt design and optimisation – crafting, testing and iterating prompts for accuracy, consistency and cost-efficiency
• Context engineering
• Prompting techniques – Strategizing prompting techniques, and inventing on the fly when needed
• Hands-on software development experience, preferably in Python or Java, with the ability to build internal tools, develop analysis pipelines and automation scripts, interpret system specifications and technical documentation.
• Harness engineering and tooling
• Evaluating and selecting foundation models for specific use cases
• Establishing guardrails – content filtering, output validation, safety checks
• Building evaluation pipelines – automated test suites and regression testing to catch prompt/model drift
• Version-controlling prompts alongside code – prompt registries, CI/CD for prompt changes
• Monitoring production LLM behaviour – latency, token costs, output quality, failure rates
• Setting up A/B testing frameworks to compare prompt or model variants

Job requirements

Experience in the following areas will be considered an asset:

• Collaborating closely with developers to integrate LLMs into applications
• Agentic frameworks and orchestration tooling
• Evaluating foundation models across multiple providers
• CI/CD pipelines
• Working in agile teams
• Prior experience with fine tuning transformer-like models or local LLMs
• Dataset creation, curation and augmentation

Why join us?

• Work on meaningful AI projects with real-world impact
• Hybrid work model
• Be part of a collaborative, agile team environment
• Opportunity to grow your skills and work with cutting-edge LLM technology
• Culture that values quality, ownership and continuous learning
