About the role
- We're looking for a Senior Full Stack Engineer with a strong frontend core - someone who thinks in React/Next.js first, but is fully capable of contributing at the backend layer using Golang when needed.
Responsibilities
- Lead frontend architecture and experience design - owning React/Next.js interfaces end-to-end, with a focus on performance, UX, and scalability.
- Collaborate tightly with product and design on experience decisions - not just implementation.
- 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.
- If you thrive on client impact, innovative product design, and tackling complex problems, Avantos is the place for you.
Requirements
- Solid backend competency - ideally Golang, but strong API design fluency is required.
Nice to have
- AI, fintech, or data-intensive product experience.
- Edge rendering, observability tooling, or event-driven architecture familiarity.
- Experience with relational databases (Postgres)
- Opportunity to define the technical foundation of a greenfield AI platform.
- A culture optimized for engineering excellence, focus, deep work, and ownership - not ticket factories.
Compensation
- Competitive compensation + meaningful equity.
Benefits
