Senior Platform Engineer

ABOUT US

Rifa AI https://rifa.ai is building the AI agents platform for contact centers in regulated industries.

Enterprises in these industries want AI agents handling their customer operations and mostly can't deploy them. It's not a model problem. Horizontal platforms lack governance, release processes, and change management, and in a domain where every call can be reviewed by a regulator, that's disqualifying. Building an AI agent has never been easier. Deploying one an enterprise can trust has never been harder. That harder problem is the one we work on.

Our platform turns a company's written procedures into AI agents: voicebots that hold real-time conversations, take actions in the client's CRM, and stay within the limits the client has set. Every release is gated by an automated testing suite, and every conversation feeds a post-analysis platform. We're live in production today, handling debt collection calls for US financial services clients.

The engineering convictions behind it: evaluation methodology, not model capability, is the bottleneck. Every rule and decision trace becomes part of a company's context graph. Observability goes beyond logging. And our Agent Studio lets engineers, non-engineers, and auditors collaborate to build and improve AI agents with the right guardrails to achieve the expected business outcomes.

Rifa was founded by Sameer Fulzele https://www.linkedin.com/in/sameerfulzele/ (IIT Bombay). We're a small team of exceptionally capable, passionate engineers with paying enterprise clients and growing revenue, backed by Seaborne Capital https://www.seabornecap.com, a founder-first firm of exceptional industry operators that works closely with its founders, and by angel investors who are veterans of enterprise software and operators in the accounts receivable industry.

ABOUT THE ROLE

While Agent Engineers own individual client deliveries, you own the platform underneath all of them: the runtime that agents execute on, the voice infrastructure that keeps live calls fast and stable, the enterprise capabilities that get us through security reviews, and the intelligence layer that turns millions of conversations into insight. This is the highest-leverage engineering seat in the company: every improvement you ship reaches every client at once.

You'll work directly with the founder on architecture and own your decisions end to end, from design through production and the incident channel.

WHAT YOU'LL DO

- Build the agent platform primitives. Design and evolve the runtime, orchestration engine, and the systems behind Agent Studio: how agents are defined from written procedures, how they reason and take actions, and how guardrails make out-of-bounds behavior impossible rather than unlikely. Building agents is its own engineering discipline, and you'll be building the tooling that discipline needs.

- Own the voice infrastructure.
