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
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Technical & Mobile Platform Strategy
- Set Technical Vision: Establish and communicate a technical vision that aligns with business goals, making pragmatic architectural decisions across web, cloud, and mobile platforms.
- Platform Evolution: Oversee our continued migration from an AWS EC2 monolith toward AWS EKS microservices, ensuring system reliability, security, and long-term scalability.
- Mobile Ecosystem Leadership: Drive high technical standards across our native and cross-platform mobile apps, mastering the nuances of mobile performance, deployment, and app store ecosystems.
- Champion Engineering Excellence: Establish high standards for code quality, continuous testing, and proactive management of technical debt with an AI-first lens.
Delivery, Operations & AI-First SDLC
- Transform to an AI-First Team: Lead the transition from traditional agile delivery to an AI-first software development lifecycle—leveraging developer tooling and CI/CD intelligence to fundamentally change how engineers work and what they achieve.
- Measure Progress: Utilize industry-standard framework metrics (such as DX Core 4) to track team performance, remove delivery bottlenecks, and validate the efficiency gains of our AI transformation.
- Cross-Functional Alignment: Partner closely with Product Management, Commercial teams, and executive leadership to balance feature delivery (especially mobile-first initiatives) with platform maintenance and technical debt.
- Incident & Vendor Leadership: Take the lead during high-priority technical incidents, coordinating calm, swift resolutions, while managing key vendor relationships and external software partnerships where required.
