Senior Full Stack Engineer

Nimble's Platform team owns the infrastructure and product surface that the entire R&D org builds on - and that customers interact with every day.

We're looking for a Senior Fullstack Engineer with exceptional frontend depth, strong backend platform experience, and hands-on AI product skills. On the FE side, you'll own Nimble's frontend platform end-to-end - setting the architecture, standards, tooling, and guardrails that allow every R&D engineer to contribute UI code to production without compromising quality. On the BE side, you'll be a core contributor to the platform infrastructure that powers Nimble at scale - API Gateway, SDK, microservices, and platform-layer features. Two halves, one owner.

Requirements:

8+ years of backend experience, with meaningful time on infrastructure, microservices, and internal platform development - gained at large-scale web companies or fast-growing, successful startups.
8+ years of frontend experience - deep, production-grade, customer-facing. You are the person others come to when FE gets hard.
Proven experience building frontend platforms or enabling systems - not just shipping features, but building the foundation others build on top of.
Deep command of the modern web stack: TypeScript, React, Next.js, Vercel, Cloudflare, and the patterns around state, data fetching, testing, and automation.
Hands-on experience with FE automation: testing frameworks, CI pipelines, linting, and quality enforcement at scale.
Experience with AI product development - you've shipped AI-integrated features in production.
Strong product sense - you can tell when something is over- or under-built, and you push back on both.

Who You Are

Frontend-first, but full-stack capable - you lead with FE depth and back it up with solid backend instincts.
A multiplier - you think about how to make every engineer around you a better frontend contributor.
High ownership mentality - you identify what needs to be done and drive it without being asked.
A collaborator who raises the bar - mentors naturally, communicates clearly, and makes the teams they touch better.

Responsibilities:

Own Nimble's frontend architecture and platform - from design system and component library to CI/CD, testing automation, and contribution standards.
Build the tooling, guardrails, and workflows that enable every R&D engineer to ship FE code confidently and safely - regardless of their frontend depth.
Set and enforce frontend standards across the organization - code quality, performance, accessibility, and consistency.
Drive cross-R&D infrastructure: API Gateway, SDK design, versioning, and microservices standardization.
Own platform-layer features: Billing, RBAC, Authentication & Authorization, usage systems, and monitoring.
Contribute to AI-native platform capabilities including agentic features and MCP integrations.

About us:

Nimble is the real-time web search platform built for enterprise accuracy, completeness, and trust. We run Web Search Agents that actively navigate live websites using real browsers and reasoning, turning the public web into governed, decision-grade data for AI systems and high-stakes business use.

Unlike index-based “AI search” tools or brittle legacy scraping, Nimble makes the live web queryable on demand, delivering structured outputs that teams can verify and rely on. Our platform powers use cases where correctness matters: financial due diligence, real-time pricing and promotions, market intelligence, and AI systems that depend on fresh, complete data.

Trusted by leading enterprises like Home Depot, Uber, and Coca-Cola and backed by top-tier investors, Nimble sits at the intersection of AI, automation, and real-time web intelligence.

As demand accelerates across AI, LLMs, and data-driven decisioning, we’re scaling quickly and looking for high-energy, driven teammates who thrive in fast-moving environments and want to help define a new category.
