The Opportunity
The Economist Group is a global media and information services company committed to championing progress. We equip individuals and organisations with expertise, insights, and perspectives to navigate change and drive growth.
This is a full-time role at the centre of our new AI Lab, a small team exploring how generative AI might shape the future of Economist journalism. This role will focus on building and fine-tuning LLM-powered systems with a particular focus on editorial tone, style transfer, retrieval workflows, and multimodal generation (especially audio).
You’ll ship products from zero-to-one and see your ideas directly influence how millions of readers interact with our journalism. If you enjoy working close to design, iterating fast, and building novel interactions across text, voice, and visuals, we’d love to hear from you. You'll be one of the first three engineers in a dedicated lab, working alongside the Tech Lead, Design Lead, and Product Lead.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You’ll Do
- Fine-tune large language models (LLMs) for style and tone alignment with The Economist’s editorial voice
- Design, curate, and manage datasets used for fine-tuning, including versioning and annotation workflows
- Build and evaluate RAG pipelines that incorporate retrieval from structured content
- Prototype and test TTS (text-to-speech) pipelines for use in audio-first products (leveraging tools like ElevenLabs, OpenAI TTS, etc)
- Collaborate with infra, frontend, and design leads to ship internal tools and demos that explore GenAI capabilities
- Own quality evaluation pipelines (BLEU, ROUGE, editorial scoring, custom evals), including human-in-the-loop feedback loops
- Support product experiments where real-time generation, summarisation, or personalisation are being tested
- Partner directly with journalists and editors to develop novel evaluation metrics that capture the nuances of The Economist's tone and style
What We Are Looking For:
- 3+ years experience building with LLMs or NLP pipelines (ideally hands-on with OpenAI, Claude, Cohere, Gemini, Mistral, HuggingFace)
- Experience with supervised fine-tuning (SFT), prompt tuning, or instruction tuning on proprietary datasets
- Strong understanding of fine-tuning paradigms, from SFT to the principles behind RLHF/RLAIF preference modeling
- Strong Python skills, including working with LangChain, HuggingFace Transformers, and data pipelines (Pandas, DVC, Weights & Biases)
- Comfortable defining and tracking generation quality with eval metrics like BLEU, ROUGE, and building editorial-specific evaluators
- Exposure to STT / TTS tools for prototyping (e.g., Whisper, ElevenLabs, Bark, etc.)
- Strong communication and collaboration mindset — able to work closely with editorial and product stakeholders
- Curious and exploratory — comfortable working in ambiguity and pushing the boundaries of GenAI capabilities
Strong Candidates Might Also Have
- Experience fine-tuning models for style or persona (e.g. chatbots with specific character voices)
- Exposure to LangSmith or similar observability tools for prompt / LLM testing
- Knowledge of voice synthesis, cloning, or emotion conditioning in audio pipelines
- Previous work in media, journalism, podcasting, or content production contexts
- Familiarity with multi-modal generation (text + image + audio), or interest in pushing toward that frontier
- Contributions to open-source LLM tools or libraries
- An interest in the ethical, editorial, and philosophical questions raised by AI-generated content

More About the Economist AI Lab
We believe AI will fundamentally change both our business and the world around us, making our mission more vital than ever. While we already use AI across The Economist Group, we think the changes to come in the next few years could be even more far-reaching.
This is why we are launching the Economist AI Lab - to reimagine Economist journalism for an AI-driven world. It is a deliberately ambitious project, exploring new ideas and possibilities beyond our existing AI initiatives and engineering roadmap.
A small, dedicated team, the AI Lab will serve as an innovation engine for The Economist – investigating bold new ideas that will shape how we serve our global audience in the future.
