Role Overview

We are looking for a hands-on AI Engineer to design, build, and deploy intelligent systems across a range of client environments. This is a technically deep role suited to someone who thrives at the intersection of machine learning, software engineering, and product thinking. You will work across the full AI development lifecycle — from prototyping and model integration to production deployment and ongoing optimisation. The ideal candidate is fluent in modern AI tooling, thinks in systems, and can translate complex technical concepts into scalable, working solutions.

Key Responsibilities

Design and build AI-powered features, pipelines, and automation workflows from scratch

Integrate and fine-tune LLMs, embedding models, and other ML systems into production applications

Develop and maintain RAG pipelines, vector search systems, and agent-based architectures

Write clean, well-structured code across backend and API layers to support AI feature delivery

Evaluate, benchmark, and iterate on model outputs to ensure quality and reliability

Collaborate with cross-functional teams to scope requirements and architect AI solutions

Stay current with the rapidly evolving AI landscape and proactively introduce relevant tooling and approaches

Document technical designs, system behaviour, and deployment processes clearly and thoroughly

Required Qualifications

Strong programming skills in Python; solid understanding of software engineering fundamentals

Hands-on experience building with LLMs (OpenAI, Anthropic, Mistral, or similar) via API and SDK

Practical experience with RAG architectures, vector databases (Pinecone, Weaviate, Chroma, etc.), and prompt engineering

Familiarity with AI agent frameworks such as LangChain, LlamaIndex, AutoGen, or CrewAI

Solid understanding of REST APIs and experience integrating third-party services and data sources

Ability to work autonomously in a fast-paced remote environment with minimal hand-holding

Must have prior remote work experience, be fluent with remote collaboration tools and platforms (such as Slack, Zoom, Google Workspace, Asana, or similar), and have ideally worked with US or UK-based companies. Applications without this experience will not be considered.

Preferred Qualifications

Experience with model fine-tuning, RLHF, or custom training workflows

Familiarity with MLOps tooling and model deployment pipelines (Docker, cloud functions, etc.)

Exposure to multimodal systems (vision, audio, or document understanding)

Background in data engineering or working with structured/unstructured data at scale

Contributions to open-source AI projects or a strong public portfolio of AI work

Tools & Technology

Python, REST APIs, and relevant AI/ML libraries

LLM platforms: OpenAI, Anthropic, Mistral, Hugging Face

Vector databases and embedding infrastructure

Agent frameworks: LangChain, LlamaIndex, CrewAI, or similar

Cloud infrastructure (AWS, GCP, or Azure)

Google Workspace, Slack, Zoom, and remote collaboration tools
