Job description

Overview

Capita is on the lookout for a skilled Java Developer to help shape a cutting-edge business scheduling solution built on data-driven optimisation. You’ll collaborate across disciplines to deliver innovative outcomes that maximise business value through robust algorithmic design.

Job title: Senior Java developer

What you’ll be doing

This hands-on role will involve:

• Supporting the development and implementation of a solution incorporating mathematical optimisation
• Translating customer needs into structured data for use in an optimisation engine — from definition and implementation to testing and documentation
• Collaborating with Business Analysts to understand client requirements
• Working alongside service designers and optimisation specialists to shape the solution
• Building an initial prototype and minimum viable product
• Delivering associated tasks including the full testing cycle and documentation
• Carrying out other tasks as required to meet client needs
• Proactively identifying and addressing inefficiencies within scope

What we’re looking for

Essential:

• This role requires eligibility for Security Clearance. Applicants must have been resident in the UK for the past five years.
• Strong coding experience in Java (essential)
• Practical experience building solutions to real-world optimisation problems using tools such as Cplex, Gurobi, or Xpress
• Solid understanding and practical experience of Agile methodologies (essential)
• Experience in evaluating and tuning performance of data extraction and manipulation functionality
• Experience of linear programming and mixed integer programming
• Familiarity with algorithmics beyond mathematical programming, such as graph algorithms, approximation algorithms, heuristics, constraint programming, and dynamic programming
• Understanding of parallel processing and hardware implementation aspects of mathematical algorithms
• Experience in performance tuning of optimisation solutions
• A background in Government or Secure Services, or experience on similar projects, is desirable but not essential. However, experience working with data in highly secure and regulated environments is critical.
