Role Overview
I'm working with a highly successful buy-side investment manager that's investing heavily in software engineering, data platforms and AI as part of a firm-wide technology transformation.
They're looking for a Senior Software Engineer to join a small, high-performing team where engineers have genuine ownership, work directly with investment, finance and operations teams, and deliver technology that has a visible impact across the business.
This isn't a role where you'll spend years maintaining a single application. You'll lead projects from design through to deployment, building modern business systems, cloud data platforms, APIs, automation and AI-enabled solutions that support the firm's investment platform.
The business has embraced AI-assisted engineering, with developers actively using Claude Code, OpenAI Codex and modern AI tooling as part of their day-to-day development process while exploring agentic workflows across the organisation.
What You'll Be Working On
Reasons to use Rodeo
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.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
