About The Role
We are looking for a hands-on technical leader to lead Penta’s Data Science team: someone who still designs, builds and reviews real solutions while owning execution, delivery and team development. You will be accountable for turning data science capability into shipped, dependable value for our clients and advisory teams, in alignment with our product roadmap.
Penta’s technology makes client outcomes sharper, faster, more differentiated and harder to replace. The Data Science team’s success is measured by how much it improves live client work, not by technical elegance in isolation.
Our core data science focus is natural language understanding at scale, processing millions of articles daily across stakeholder sentiment, topic identification over time, competitive peer-set selection, summarisation, contextualisation and other processing of unstructured content. Most use cases are creative chains of multiple steps drawn from data processing, exploratory analysis, fundamental ML, NLP, SQL, LLMs and integration into our live systems.
What You’ll Do
Lead the team
Manage, coach and develop Penta’s Data Science team, setting priorities, planning capacity and creating a high-trust, high-output delivery culture. Translate the product roadmap and advisory needs into a focused data science plan, partnering with Product, Advisory, Database, Development and DevOps teams to keep delivery aligned with client outcomes. Raise the delivery bar for execution, quality, pace, maintainability and cost discipline.
Ship production data science and AI systems
Design, build and review data science solutions across NLP, LLM workflows, machine learning, SQL and large-scale content processing. Own technical design and architecture for data-science-enabled applications, ensuring solutions are maintainable, supportable, observable and easy to operate. Productionise delivery with DevOps and MLOps, automating deployment in AWS and puttinge evaluation, monitoring and provider-routing controls in place so AI outputs remain reliable and cost-effective.
Scale practical AI adoption
Design and implement AI workflows as skills, models and MCP tools in OpenWebUI, with cost control, provider routing and observability built in. Partner with other departments to turn AI capabilities into everyday workflows, reusable tools and knowledge layers that improve internal productivity and client delivery. Evaluate emerging AI tools, models and agentic patterns, bringing the useful ones into production quickly and responsibly.
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.
Success in this role
Means the Data Science team is shipping reliable, maintainable AI and analytics capabilities into live client and advisory workflows; team members are growing; delivery is predictable; and Penta’s applied AI capability is visibly improving across products and engagements.
The Team
Our Technology team supports Penta’s ambitious delivery plans, using technology to automate solutions, optimise outcomes and support continuous integration and deployment. The six-person Data Science team sits alongside Development, Engineering / DevOps & Platform Security, IT and the PMO, and works hand in hand with the Product team.
The environment is collaborative, pragmatic and delivery-focused. We move quickly, share ideas openly, and use regular hackathons and experiments to generate practical business value.
This is the hands-on leadership role for that team. Reporting to the CTO, You will lead a team working at the frontier of applied AI and data science, combining production LLM workflows, advanced prompting, agentic tooling, NLP, ML and large-scale content processing. You will set its direction, raise its delivery bar, grow its people through hands-on coaching, and lead from the front by actively shaping and delivering the work yourself.
Our approach to AI is practical
We are forward-thinking and ambitious in practically applying AI across client-facing work, corporate teams, technology and data science. We do not train our own foundation models; we apply, orchestrate and evaluate the best available models from major providers, engineering them into robust workflows that solve real business problems.
We validate and document our methodologies through white papers and technical explainers, setting out the academic and analytical foundations behind our products, and the evidence that supports their use. This helps build trust in our tools, why they work and shows how they can be applied.
We build on open-source AI software, including LiteLLM and OpenWebUI, to maximise the internal value of AI and build durable institutional capability. Reliability, cost control, observability, instruction-following, usability and adoption matter most.
The team designs reusable workflows, skills, models and MCP tools that support Penta’s move towards an AI-native advisory operating system. Keeping Penta at the forefront of practical AI in PR, communications and strategic consultancy is part of the role.
