Avantos is the AI native operating system for client management, delivering a new operating layer with AI agents that power onboarding, servicing, and growth while fitting seamlessly into your existing technology stack. Backed by Bessemer.
About the role
Avantos AI is shaping the future of client relationship management by reimagining it through the lens of artificial intelligence. We are building the industry’s first AI-native operating system for financial services, transforming how firms onboard clients, deliver advice, and manage critical servicing workflows. Our platform consolidates fragmented data, automates complex processes, and embeds intelligent decision-making throughout every stage of the client lifecycle.
What they're looking for
- 3+ years of engineering experience building production web applications
- Expert-level frontend depth — React + Next.js mastery (streaming, modern rendering patterns, state strategy)
- Proven ability to design high-performance, scalable, modern frontend systems with clarity and intentionality
- Solid backend competency — ideally Golang, but strong API design fluency is required
- Deep understanding of performance, caching, hydration, code splitting, bundling, deploy strategy, DX/UX tradeoffs
- Product and architecture instincts — you care about what should be built, not just how
