About the Role
Were looking for a Machine Learning Engineer to design, build, and optimise next-generation Conversational AI systems that power intelligent, human-like digital assistants across the public sector. This is a permanent position offering remote working and flexibility with occasional client visits, expenses covered.
Youll work on agentic AI workflows, fine-tune large language models, and ensure our systems are reliable, explainable, and secure - directly contributing to innovations that help government services run smarter and faster.
What Youll Do
* Design & Build: Develop agentic AI workflows using frameworks like LangChain or LlamaIndex for complex, multi-step reasoning.
* Model Optimisation: Fine-tune LLMs to improve accuracy, reduce latency, and lower infrastructure costs.
* Evaluation & Reliability: Build robust model evaluation frameworks to ensure consistency across model and code changes.
* Core Engineering: Develop scalable backend services in Python 3 with Git, FastAPI, or Django REST Framework .
* Cloud Integration: Work with Google Vertex AI, Amazon Bedrock, and Azure AI to integrate foundation models and APIs.
* Contextual Retrieval: Use vector databases and retrieval systems to enhance contextual understanding.
* Collaboration: Partner with data scientists, engineers, and designers to continuously improve agent performance and reasoning.
Who You Are
Youre a hands-on engineer whos excited by the intersection of AI, language, and systems engineering - someone who thrives in a collaborative, mission-driven environment.
You bring:
* Proven experience deploying machine learning models into production environments.
* Strong Python skills and experience with LLM frameworks (LangChain, LlamaIndex, HuggingFace Transformers).
* Knowledge of conversational AI platforms (Dialogflow, Lex, Rasa).
* Familiarity with TensorFlow, PyTorch, Keras, scikit-learn, and Pandas .
* Experience integrating with cloud-based AI services (AWS, Google Cloud, Azure).
* The ability to communicate complex technical concepts clearly and confidently.
Desirable (Not Essential)
* Experience with AI application interfaces (MCP protocol).
* Knowledge of multi-agent orchestration (LangGraph, AutoGen, CrewAI).
* Familiarity with AI safety and observability tools (TruLens, Helicone, Guardrails AI).
* Experience with Axolotl, LoRA, or QLoRA fine-tuning methods.
Why Join Us
* Work on cutting-edge AI systems that make a tangible difference in how public services are delivered.
* Fully remote, flexible culture.
* Contribute to meaningful projects in science, innovation, and technology.
* Rapid, 1-stage interview process no bureaucracy, just great conversations.
