Senior .NET Software Engineer - £700-750pd (Inside IR35)

We are partnering with a Lead Energy Trading Client who are searching for a Senior C# Developer with ETRM experience to join their team.

Key Responsibilities:

  • Develop and enhance integrations with the ION Openlink (Endur) platform (experience with any external third party ETRM is ok!)
  • Design, build and maintain enterprise-grade applications using C#/.NET.
  • Perform system testing, validation and troubleshooting to ensure successful deployments.
  • Collaborate with Front Office, Risk, Operations and Middle Office stakeholders to understand business requirements.
  • Deliver high-quality solutions within challenging project timelines.

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.
