Job description

Overview

About Aviron

Aviron is building the next generation of applied AI for finance operations. Mid-market companies today run on “Frankenstein” stacks of ERPs, spreadsheets, and disconnected tools that don’t talk to each other. The result is teams bogged down in manual work, lost productivity, and talent that never gets to do its best work.

Our AI-agent platform plugs into that existing environment in days and becomes the place where financial and administrative operations actually get done. Agents handle routine workflows end-to-end – from processing invoices to reconciling accounts – while employees remain in control for approvals, oversight, and exceptions. The outcome is a digital co-worker that learns your processes, improves continuously, and frees people to focus on creativity, strategy, and growth.

As builders and problem solvers, we partner closely with our clients to identify high-impact opportunities, quantify ROI, and deliver solutions that drive measurable business outcomes. Our unique approach combines technical excellence with deep business acumen, ensuring that every implementation creates lasting value through increased revenue, reduced costs, or enhanced operational efficiency.

With every workflow automated and every team empowered, Aviron is moving closer to becoming the AI operating system for mid-market companies.

Our Mission

To create a future where humans and AI agents work side by side in true collaboration – a partnership that amplifies human strengths, unlocks potential, and enables human flourishing. We believe the real promise of AI is not replacement, but empowerment: freeing people from repetitive tasks so they can focus on creativity, insight, and impact. By pairing human ingenuity with intelligent agents, we are building a world where work is more meaningful and every individual has the opportunity to thrive.

What we value

• Customer obsession
• Speed of execution, great tooling
• Simplicity and cutting the cruft
• Collision of ideas to produce better ones
