Data Scientist - Optimisation & Applied Analytics

Contract duration: 6months (12months of work road mapped)

Day rate: 800 Inside IR35

Location/Hybrid: 2-3 days per week to Heathrow Airport

A major global airline, undergoing a multi‑million‑pound data and optimisation transformation, is looking for a Data Scientist to join their high‑performing Decision Support & Optimisation function.

This role is end‑to‑end, hands‑on, and deeply embedded in the business. You'll work at the start of new product builds, shaping and delivering AI‑powered optimisation tools that keep people and aircraft moving efficiently in one of the most operationally complex industries in the world.

What You'll Do

Build and deploy applied statistics, machine learning and optimisation models that support mission‑critical operational decisions. Work closely with data engineers, understanding their workflows and collaborating to take models from ideation all the way into production environments. Craft and define optimisation problems from scratch: decision spaces, constraints, objective functions. Use strong data visualisation and communication skills to influence stakeholders at all levels. Partner with operational teams to embed tools directly into workflows and measure real‑world impact. Own delivery end‑to‑end with far better working hours than typical consulting-while still delivering meaningful change.

What We're Looking For

Technical Expertise

Degree or Master's in Maths, Statistics, Data Science, Operational Research, or similar fields. Strong applied statistics background. Experience working with messy or complex datasets Hands‑on exposure to integer programming, MIP, MILP, and applied optimisation. Experience with optimisation tools such as CPLEX, MATLAB, OR‑Tools, or similar. Some exposure to machine learning methods. Ability to build and industrialise Python‑based data products. Exceptional communication and storytelling abilities-able to interrogate both data and stakeholders. Ability to articulate trade‑offs, design decisions and model assumptions clearly to non‑technical audiences.

Guidant, Carbon60, Lorien & SRG - The Impellam Group Portfolio are acting as an Employment Business in relation to this vacancy.

How Many AI Tools Do You Need to Know to Get an AI Job?

If you are job hunting in AI right now it can feel like you are drowning in tools. Every week there is a new framework, a new “must-learn” platform or a new productivity app that everyone on LinkedIn seems to be using. The result is predictable: job seekers panic-learn a long list of tools without actually getting better at delivering outcomes. Here is the truth most hiring managers will quietly agree with. They do not hire you because you know 27 tools. They hire you because you can solve a problem, communicate trade-offs, ship something reliable and improve it with feedback. Tools matter, but only in service of outcomes. So how many AI tools do you actually need to know? For most AI job seekers: fewer than you think. You need a tight core toolkit plus a role-specific layer. Everything else is optional. This guide breaks it down clearly, gives you a simple framework to choose what to learn and shows you how to present your toolset on your CV, portfolio and interviews.

What Hiring Managers Look for First in AI Job Applications (UK Guide)

Hiring managers do not start by reading your CV line-by-line. They scan for signals. In AI roles especially, they are looking for proof that you can ship, learn fast, communicate clearly & work safely with data and systems. The best applications make those signals obvious in the first 10–20 seconds. This guide breaks down what hiring managers typically look for first in AI applications in the UK market, how to present it on your CV, LinkedIn & portfolio, and the most common reasons strong candidates get overlooked. Use it as a checklist to tighten your application before you click apply.

The Skills Gap in AI Jobs: What Universities Aren’t Teaching

Artificial intelligence is no longer a future concept. It is already reshaping how businesses operate, how decisions are made, and how entire industries compete. From finance and healthcare to retail, manufacturing, defence, and climate science, AI is embedded in critical systems across the UK economy. Yet despite unprecedented demand for AI talent, employers continue to report severe recruitment challenges. Vacancies remain open for months. Salaries rise year on year. Candidates with impressive academic credentials often fail technical interviews. At the heart of this disconnect lies a growing and uncomfortable truth: Universities are not fully preparing graduates for real-world AI jobs. This article explores the AI skills gap in depth—what is missing from many university programmes, why the gap persists, what employers actually want, and how jobseekers can bridge the divide to build a successful career in artificial intelligence.
