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.
Integrate cleanly with backend services and contribute to Golang APIs when needed — not just consume them.
Collaborate tightly with product and design on experience decisions — not just implementation.
Influence architecture, reliability, performance strategy, and engineering standards.
Write high-quality, clean, well-structured code — and enforce that quality in reviews.
Act as a technical force multiplier — mentoring, unblocking, and setting the technical bar.
Minimum Qualifications
8+ 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.
Preferred Qualifications
AI, fintech, or data-intensive product experience.
Experience shaping design systems, frontend platforms, or reusable architecture patterns.
Edge rendering, observability tooling, or event-driven architecture familiarity.
Experience with relational databases (Postgres)
What We Offer
Competitive compensation + meaningful equity.
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.
