Senior Software Engineer, Full-Stack

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.

- 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.

- 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.

- 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)

- 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.
