About Morningstar

Our offerings include a wide range of data, research, and investment management services, with $300+ billion in assets under management. Operating in 32 countries, Morningstar supports financial advisors, asset managers, retirement plan providers, and more with comprehensive investment solutions.
The Role
We are looking for an amazing Developer to help us build and maintain our exchange connectivity software. This is a fixed-term contract for a year with a potential extension.
Market Data powers all of Morningstar, as well as our clients, so having the best technology to do this is critical to the company’s success. We receive billions of messages every day from our direct financial exchange connections, which we process into a form usable by our customers. At present, we process over 40 billion messages per day and with data volumes significantly increasing year-on-year, you can imagine how this needs a high level of engineering skill to keep it under control.
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.

You will need to work in an agile, multi-functional team of developers and testers to build and maintain our exchange connectivity components. You’ll need to be happy working in short cycles, with frequent deliveries while improving the overall quality of the development process.
Job Responsibilities
- Work within a team of approx. 4 developers and 2 QA, focused on building and maintaining our exchange connectivity software.
- You will need to be rigorous in writing efficient code and encourage continuous improvement of how we build, test, and deploy our system.
- You'll be working with a mix of experience levels so will have the opportunity to both learn and mentor depending on where you are in your career.
- There will be some out-of-hours 3rd line support, but we try to keep this to a minimum as we have a dedicated operations team who handle most issues.
Some key examples of the sort of work the team does:
- Data feed development for high volume low latency exchange connections
- Development and maintenance of key libraries used by the entire team
- Development of key underlying transport protocols for transmission of data
- Working with DevOps to improve automation in the development cycle
