About C5i
Founded in 2000, C5i enables organisations to make the most effective strategic and tactical moves relating to their customers, markets and competition, at the pace the digital business world demands. We build AI products: Agent5i, our enterprise agentic AI system; Compete, digital shelf analytics for brands selling through retail; Incivus, creative effectiveness for marketing teams; and Synthetic Audiences, virtual respondents for research teams who need an answer faster than a panel can return one. Each has its own users, roadmap, release cycle and stack today, running across Azure, AWS and GCP.
What We Seek
You own the product surface across all four products. Architecture authority and delivery accountability sit in the same seat: you define how the products are built, and you build them. The remit spans the full application layer. Frontend and interaction design for agent-driven interfaces. Backend services and APIs. Agent orchestration, tool and function calling. Integration with the systems tenants already run. Test strategy and release.
Everything a user touches passes through your design.
You hold that across four products rather than one line, so your decisions have to generalise and your conventions have to actually get reused. Agent-facing product patterns are not settled anywhere in the industry, so there is limited prior art to copy. You will make design calls on incomplete information, ship them, learn from production and revise. Doing that without ego, and without treating a reversal as failure, is a requirement of this role rather than a soft preference. Two things this seat is measured on: whether a convention written for one product gets used by the next, and whether an interface still holds after a model provider changes underneath it. Product engineering has run for a decade and is being pivoted to agent-native surfaces now, so you will replace as much as you build.
You lead nine engineers across full stack, frontend and backend. De
