Rivio <> AI Engineer (Agents)
Job Description: Software Engineer at Rivio
: San Francisco
: Hybrid - 2 days/week in person
: Full-time
: Backed by Gradient Ventures (Google AI Fund) and S32
Job Requirements:
5+ years of professional software engineering experience.
Proficiency with AI coding assistants (e.g., Claude Code, Cursor) is mandatory.
Strong grasp of agentic AI fundamentals: context management, retrieval grounding, tool/function calling, and multi-agent orchestration.
Hands-on experience with public cloud (AWS, GCP, or Azure) and building/operating data pipelines.
Proven ability to deliver in fast-paced, rapidly evolving environments.
Mission-Driven Objective / What You Will Do:
As our AI Engineer you will build AI Agents that functions as a full-time procurement manager— not just a tool. You will:
Own the agent loop end-to-end: ingest → retrieve → reason → act → learn.
Deliver grounded answers from large, overlapping corpora; extract key terms/SLAs/pricing into structured schemas.
Build action tools to execute in ERP/AP/procurement systems with audit trails, RBAC, and safe rollback.
Ship evals + observability (task success, precision@1, latency, cost) and enforce guardrails for privacy and policy.
You build it, you run it—own reliability, incident response, and continuous iteration.
What We Believe:
Problem-Solving: autonomously solve complex technical challenges and proactively address issues, always seeking to challenge the conventional ways and innovate.
Ownership: Take full ownership of projects and initiatives, especially those you’ve never worked on before. Embrace a growth mindset to continuously learn and adapt.
Adaptability: Thrive in a fast-paced, ambiguous environment typical of early-stage startups. Wear multiple hats and spearhead projects end-to-end.
Mentorship & Collaboration: Inspire and guide team members. Influence peers and stakeholders through clear communication across various levels of the organization.

It handles everything from contract analysis and communication with suppliers. We’re tackling a $1.5T market by creating the procurement workforce of the future.
We’re looking for a driven software engineer to join a team with experience from leading teams at Apple, Meta, Google and top Silicon Valley startups.
What We Offer:
Competitive salary and equity, based on experience[$150K - $200K + 0.5%-1.5% equity]
Dynamic, fun, and collaborative work environment where you can be yourself.
Major opportunities for professional growth.
Significant impact on an early-stage startup.

Why you shouldn’t join
You are not ready for the occasional 60-hour work week
You are not comfortable working without clear structure
You are not ready for a risky career opportunity. Even with our growth, we are still an early-stage startup. If you need something more predictable, this is not the right fit.
You are an ML Engineer
You don’t have GenAI experience
