TalentCo are delighted to be working with a fast-growing Agentic AI startup looking to hire several high-calibre Senior Backend Engineers into their growing engineering team in the UK, having recently closed a significant seed funding round.
This hire can be based fully-remote anywhere in the UK, for this Silicon Valley headquartered startup.
You will be at the forefront of building and scaling AI-powered applications, transforming how enterprises interact with intelligent agents. You’ll focus on developing scalable back-end systems that power real-time AI-driven workflows.
This role requires strong software engineering skills, a deep understanding of backend development, and the ability to work in a fast-paced, AI-first environment. You’ll collaborate with AI engineers, AI researchers, full-stack engineers and product teams to build enterprise-grade solutions that enable seamless AI-human interactions.
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

- Ship robust, minimal-dependency code that performs efficiently in enterprise environments.
- Continuously iterate and refine AI-driven products, balancing user needs with technical feasibility.
We want to hear from you if you have:
- 6+ years of hands-on experience building production applications, having worked in high-bar engineering environments, particularly startups or scale-ups.
- A backend focus, with proficiency in modern web technologies, namely Node.js and Typescript.
- Strong knowledge of cloud infrastructure (AWS, GCP, or Azure) and scalable architectures.
- Understanding of AI-powered applications, including LLMs, chat interfaces, and agentic workflows.
