Job description

Alana is building the next generation of AI technology to help businesses create more human, intelligent, and personalised customer interactions. We’re a company that thrives on real-world collaboration, with our headquarters based in London and expanding teams in New York and Miami. Our workplace is built on five guiding principles that shape our actions and relationships: Trust, Customer Commitment, Craft, Momentum, and Community. These are not slogans but expectations we live by every day.

What You’ll Be Doing

As an Agent / Data Engineer at Alana, you’ll build the conversational and data backbone that powers our AI agents voice and text alike. You’ll design systems that let our agents listen, understand, and respond with personality and precision. Your work will bridge data engineering, conversational design, and real-time systems to make every interaction feel alive.

Your work might include:

• Architecting pipelines that process and structure conversational data for training and evaluation
• Building frameworks for multi-turn dialogue management, context retention, and personality steering
• Developing metrics and feedback loops that improve agent accuracy, tone, and responsiveness over time
• Integrating and optimizing speech recognition, synthesis, and LLM-based reasoning for natural voice experiences
• Designing systems for retrieval-augmented and hybrid text+voice agents that adapt to context in real time
• Collaborating with product, research, and design to shape how agents think, speak, and evolve in production
• 4+ years of experience managing production-grade infrastructure

What you bring:

• 4+ years of experience in data engineering, ML infrastructure, or conversational AI systems
• Proficiency in Python or similar languages for data processing and pipeline orchestration
• Familiarity with modern data tooling (e.g.Kafka, Snowflake, vector databases)
• Comfort working with unstructured data (transcripts, embeddings, metadata)
• Experience integrating or fine-tuning LLMs and speech models
• A bias toward iteration—you believe the best systems are learned from real conversations
• A passion for human-computer interaction and what “natural” really feels like in voice and text

Extra Credit

• Experience with ASR/TTS systems
• Knowledge of RAG pipelines and agent orchestration frameworks
• Familiarity with observability, logging, and evaluation of LLM-based systems
• Experience working closely with design or research teams on conversational UX
• Contributions to open-source AI or data tooling projects
