You will lead the development of innovative data-driven software solutions to help our clients overcome a variety of science and engineering challenges, all related to the capture, storage, visualisation and analysis of complex data. Projects can span a range of activities and your responsibilities will include:

  • Oil and gas expertise: use your domain knowledge to understand the complex analytics challenges affecting our clients.
  • Requirements capture: work closely with clients to help clarify their analytics needs and suggest technical solutions and business approaches to address those needs.
  • Technical leadership: lead teams of first-class data scientists and consultants as they develop innovative analytics solutions using their expertise in data analysis, modelling and simulation, visualisation, artificial intelligence and machine learning.
  • Client facing: build strong relationships, collaborate with clients and colleagues and communicate clearly about project goals, challenges and results.
  • Project Management: successfully manage projects to ensure they are efficiently delivered within budget, on time and meet – or exceed – client expectations.


During your career at Tessella, you will be expected to learn and develop your skills, but before you join us you should have:

  • Bachelors, Masters or PhD in science, mathematics or engineering.
  • An understanding of how complex data is interpreted using a variety of analytical, statistical or machine learning techniques.
  • Exposure to computational modelling, algorithm development or software engineering in Python, R or Matlab or any of our other core languages: Java, C, C#, C++.
  • Excellent interpersonal skills and the ability to explain complex concepts to clients and colleagues from all backgrounds.
  • The eagerness and capacity to quickly learn new domains and technologies.
  • Project Management and/or Business Analysis experience or qualifications would be desirable.
  • While not essential, any experience with data analysis tools such as Hadoop or Spotfire would be an advantage.

Career Development and Training

We offer excellent prospects for your future. While we do offer traditional career paths, most staff end up shaping their own based on their aspirations, the skills they have developed and the projects they have worked on. We take personal development seriously and all staff receive an annual training allowance of 150 hours, which can be used to learn new technical and soft skills, often leading to recognised professional qualifications.

Our work is at the cutting-edge of high-tech R&D and our projects are varied and rewarding. For example, in pharmaceutical companies we solve computational problems for chemists at the early stages of drug discovery and development, allowing them to get a head start when they begin their experiments in the lab, ultimately getting drugs to market faster. We help consumer goods companies model and simulate new product ideas and perform data analysis to improve their processes. We also support oil and gas engineers with the computational challenges of exploration and production, from reservoir modelling to writing control systems. In space and defence, we have written algorithms and solved complex mathematical problems to control satellites and radar systems.
