Senior Software Engineer, Full-Stack

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.
