What You'll Be Doing
* Lead the development of Alphix’s LLM-powered features and services – from prototype to production – enabling automation, summarisation, semantic insights and next-gen user experiences.
* Design and build vector database solutions for scalable semantic search, contextual analysis, and real-time decision-making.
* Work cross-functionally with product, engineering and data teams to deploy machine learning models in a production environment, with real users and measurable impact.
* Research and implement novel AI/ML techniques– from RAG pipelines and embedding optimization to custom LLM tuning – to solve real-world marketing challenges.
* Champion ML best practices, robust pipelines (MLOps), and high-quality model monitoring.
* Constantly explore emerging tools and integrate them where they create real business value.
About You
* You’re a creative builder, excited by the chance to develop intelligent systems that didn’t exist before.
* Deep hands-on experience with:
* Deployment of ML models at scale
* You’ve built and deployed AI/ML solutions that had real, measurable impact for clients or internal users, and you can talk us through them.
* You have a strong foundation in machine learning, NLP, data engineering and model architecture.
* Curious, collaborative and self-directed, you thrive in environments where ambiguity = opportunity.
* You care about user experience and business outcomes as much as you do about algorithmic elegance.
Why Join Alphix?
* Break new ground: We’re building the next generation of marketing intelligence from first principles, not retrofitting old tech.
* Own your impact: Your work will touch real users, drive decision-making, and be a core part of the product roadmap.
