FTSE Russell, a leader in global indexing and analytics, is seeking a skilled and motivated Software Engineer to build robust, scalable applications that support trillions in assets. The ideal candidate will have a deep understanding of software development, the ability to drive complex projects to successful completion, and a willingness to learn.

As the Software Engineer, you will be involved in developing and supporting the delivery of various engineering and automation initiatives. You will be responsible for delivering high-quality software on time and fostering a culture of innovation and continuous improvement.

  • Develop clean, efficient, and secure backend code in C#.NET and cloud-native architectures.
  • Create intuitive, responsive UIs using Angular and modern JavaScript frameworks.
  • Implement RESTful APIs, microservices, and automated CI/CD pipelines for rapid delivery.
  • Work with big data systems and databases like SQL Server, Sybase, and PostgreSQL.
  • Help shape a world-class engineering culture.
  • Partner with global teams to define new solutions across cloud, data, and analytics.
  • Analyse production problems and provide troubleshooting and support.
  • Work with upstream and downstream development teams to implement functionality.
  • Work with QA teams to design test cases and implement automated test drivers.
  • Promote a culture of teamwork, high performance, and quality via code reviews, ensuring standards and best practices are followed via agile methodologies.
  • Communicate with clarity, precision, and influence, presenting complex information in a clear and concise format that is appropriate for the audience.
  • Drive a culture of engineering excellence and promote standard methodologies in software design and development.

Frontend: Angular, JavaScript, HTML5/CSS

Cloud: AWS (EC2, Lambda, Glue, EKS, SQS, SNS)

Databases: SQL Server, Sybase, PostgreSQL

Testing: MSTest, tSQLt, BDD tools (Cucumber, Mocha)

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

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.
