Join Barclays as a Back End Developer for our Loan IQ project and be part of an Agile, sprint-based environment where your impact truly matters. You’ll work within a POD-structured team aligned to clear streams of work, owning the full lifecycle from initial design and deep analysis through implementation and testing, while also mentoring and developing more junior developers. We’re looking for an experienced, confident back-end engineer who thrives in changing priorities, loves solving complex problems, and is adaptable and eager to learn new programming languages and technologies. Banking or Loan IQ experience is a plus (not a must), with nice-to-have exposure to MongoDB, Oracle, Tableau, Wholesale Lending, or XQuery — but above all, we value curiosity, learning mindset, and strong problem-solving skills over specific tech stacks.

To be successful in this role, you will need the following:

  • Software engineering background with experience in Java and/or XQuery.
  • Strong problem solving capability with the ability to investigate issues, identify root causes, design effective solutions, and constructively challenge requirements or proposed approaches to drive continuous improvement.
  • Ability to clearly explain complex or technical concepts to diverse audiences, ensuring shared understanding and alignment.
  • A proactive and enthusiastic approach to learning new technologies, programming languages, and methodologies.

Some other highly valued skills include:

  • Exposure to MongoDB and Oracle is desirable, with Tableau development experience considered an advantage.
  • Experience in Wholesale Lending and banking environments. Familiarity with Loan IQ and Wholesale Lending platforms is preferred.
  • Proven ability to operate effectively within Agile teams, contributing to iterative delivery, continuous improvement, and collaboration across functions.
  • Strong adaptability and prioritisation skills, with the ability to manage shifting priorities and adapt to changing business needs while maintaining high quality delivery.

You may be assessed on the key critical skills relevant for success in role, such as risk and controls, change and transformation, business acumen, strategic thinking and digital and technology, as well as job-specific technical skills.

The successful candidate will be based in Knutsford (Radbroke Hall).
