Full Job Description
Company Overview 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. Supported by Bessemer Ventures and MIT’s investment arm, our team comprises execution-focused, design-driven, product-centric founders and leaders from Wharton, MIT, top design programs, and unicorn SaaS companies. We move swiftly, tackle deep industry challenges, and build technology that empowers users to take charge of their workflows.

Minimum Qualifications - 8+ years of engineering experience building production web applications. - Expert-level frontend depth — React + Next.js mastery (streaming, modern rendering patte
