Company Description: Rivulo.ai - VC-backed AI automation startup
As the first technical hire, you will own the architectural evolution of an agentic workflow platform. Transitioning the codebase from the technical co-founder, you'll build robust systems that convert real-world behaviours into reliable AI automations. You will bridge the gap between complex LLM orchestration and seamless user experiences for non-technical teams.
Location: London, UK
Why this role is remarkable:
- Take total technical ownership as the first engineering hire, working directly with experienced founders who have multiple successful exits.
- Experience a high-trust, radical transparency culture with self-management, full financial visibility, and the autonomy to make major architectural decisions without red tape.
What you will do:
- Evolve the platform architecture from v1 MVP to a scalable, production-grade system capable of handling thousands of concurrent AI workflows.
- Design and implement sophisticated LLM integrations, focusing on prompt engineering, token management, and real-time streaming reliability across OpenAI, Anthropic, and Google APIs.
- Collaborate directly with customers to understand friction points, translating messy real-world operational needs into elegant, automated agent-led systems.
The ideal candidate:
- Proven track record in AI Engineering, including hands-on experience with LLM context window optimization, rate limiting, and building resilient retry logic for real-time interfaces.
- Entrepreneurial builder who thrives in autonomous environments, possesses a founder mindset, and is comfortable jumping into product or support tasks to drive company growth.
