The Role

We’re looking for Senior Software Engineers to join our Joule Direct team, to help us build and improve our high-throughput, low-latency energy trading platform. You’ll be working with some amazing technologists to solve complex problems.

For us, teamwork is everything. We listen to each other, we adapt, we evolve and we strive to innovate. We are making significant investments in our business and we will invest in you.

Some of the work on any given day includes:

  • Improve how we connect to an Exchange or Broker (e.g. CME, ICE, EEX, etc)
  • Implement customer facing features via SDKs and APIs
  • Improve observability in hot paths
  • Implement a new Automated Trading feature
  • Benchmarking code to reduce latency and improve throughput
  • Mentoring and coaching junior engineers
  • Design, plan and execute complex features and raise RFC’s

Our Tech Stack

  • We use GitHub Copilot for agentic development
  • Our services are written in modern C# and Rust
  • We use a fair bit of SQL databases, Kafka, and RabbitMQ
  • We run some services on dedicated hardware and on AWS
  • We use Azure DevOps for build/deploy pipelines and story management
  • Our observability stack is Splunk, Grafana, Pyroscope and Prometheus

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.
