We are working with a lean, rapidly scaling startup that is at the forefront of innovation, building a cutting-edge workflow and intelligence platform. This platform is powered by advanced agentic AI, sophisticated multimodal analysis, and deep domain-specific insights, poised to disrupt its industry.

The Role

  • Develop and implement end-to-end architecture, security, performance, and integrations for AI applications.
  • Build production systems leveraging deep Firebase expertise (Firestore, Cloud Run, Auth, Security Rules).
  • Work closely with the Head of Product to transform specifications and prototypes into production-grade code.
  • Lead the growth of the engineering function, including hiring, structuring, and mentoring a team.
  • Drive the technical vision and strategy, with a clear trajectory to assume the CTO position as the company expands.

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.
