Qwoted

<div>
 Qwoted is transforming how the media and the communications world connect. Every day, thousands of journalists and PR professionals rely on Qwoted to surface the right expert, at the right moment, with the right insight. We&rsquo;re scaling fast &mdash; enriching millions of articles, building powerful vector-based matching engines, and delivering AI-driven tools that help both media and communicators do their jobs better. As we expand our engineering team, we&rsquo;re looking for a senior technical leader who wants to sit at the heart of this transformation.
 
 
 We are looking for a frontend specialist to lead the transformation of our product into a modern, JavaScript-heavy, cross-platform experience. We&rsquo;ve already built a solid foundation of APIs (Postgres + Rails + Supabase), and our backend team is in place. Now we need someone to own and architect the frontend layer: rewrite our web application, create our first cross-platform mobile app, and deliver polished, consumer-ready interfaces.
 
 
 This is not a backend or full-stack role. If your passion is databases or Rails, this isn&rsquo;t for you. We want a frontend-first developer who thrives in React, loves building beautiful interfaces, and knows how to bring web technologies to mobile through Capacitor.
 
 
 Our inspiration is the LinkedIn + LinkedIn Mobile App experience &mdash; but laser-focused on the media industry. This is your chance to help define the user-facing side of an enterprise social network from the ground up.
 
 We need someone with passion and a vision for the future of Qwoted.
 
 
 
 
 What You'll Do
 
 
 
 <ul>
 <li>
 Lead and mentor a team of front-end and full-stack engineers; set coding standards, conduct reviews, and cultivate a high-performance culture.
 </li>
 <li>
 Architect and build Qwoted&rsquo;s first mobile app (iOS &amp; Android) using Capacitor
 </li>
 <li>
 Rewrite and modernize our frontend web application, aligning it with the same technologies and UX patterns used in mobile
 </li>
 <li>
 Work closely with our UX designers to deliver interfaces that are responsive, accessible, and delightful
 </li>
 <li>
 Collaborate with backend engineers by consuming APIs, not building them
 </li>
 <li>
 Push UX forward &mdash; animations, accessibility, responsiveness, and performance tuning
 
 
 
 
 </li>
 </ul>
 
 Our Current Stack
 
 
 
 <ul>
 <li>
 React 18.3.1 with 150+ components
 </li>
 <li>
 ESBuild for bundling
 </li>
 <li>
 Supabase + Postgres/Rails APIs
 </li>
 <li>
 Bootstrap 5 + React Bootstrap
 </li>
 <li>
 Algolia for search
 </li>
 <li>
 OneSignal for push notifications
 </li>
 <li>
 Jest + React Testing Library for testing
 
 
 
 
 </li>
 </ul>
 
 Who We're Looking For
 
 
 
 <ul>
 <li>
 Deep React expertise (5+ years)
 </li>
 <li>
 Cross-platform mobile development experience, preferably with Capacitor
 </li>
 <li>
 Strong grasp of modern JavaScript/TypeScript
 </li>
 <li>
 Ability to turn designs into elegant, performant, accessible experiences
 </li>
 <li>
 Experience working with UX designers to deliver consumer-quality interfaces
 </li>
 <li>
 Independent, self-directed problem solver who can take high-level requirements and run with them
 </li>
 <li>
 Proven history of leading engineering teams, mentoring developers, and driving execution
 </li>
 <li>
 The ability to produce impeccable code that requires very little review by our CTO
 </li>
 <li>
 Experience building beautiful and performant apps that are available from the app store
 
 
 
 
 </li>
 </ul>
 
 Bonus Points For
 
 
 
 <ul>
 <li>
 Experience with PWAs, push notifications, or real-time interfaces
 </li>
 <li>
 Familiarity with Algolia, Storybook, or modern CSS patterns
 
 
 
 
 </li>
 </ul>
 
 What Makes This Role Different
 
 
 
 <ul>
 <li>
 You&rsquo;ll be the first dedicated frontend/mobile specialist at Qwoted
 </li>
 <li>
 You&rsquo;ll set the tone for how we build client-side software going forward
 </li>
 <li>
 You&rsquo;ll focus on frontend only &mdash; with less need to context switch into backend concerns
 </li>
 <li>
 You&rsquo;ll help define our mobile-first strategy from scratch
 
 
 
 
 </li>
 </ul>
 
 Success Looks Like
 
 
 
 <ul>
 <li>
 Launching the Qwoted mobile app within 6 months
 </li>
 <li>
 Launching Version 2 of our frontend web application
 </li>
 <li>
 Establishing a reusable component system that works across both web and mobile
 </li>
 <li>
 Driving measurable adoption through improved UX and performance
 
 
 
 
 </li>
 </ul>
 
 Please Include These Things In Your Application
 
 
 
 <ul>
 <li>
 Your resume or CV so we can learn about your background
 </li>
 <li>
 A portfolio of React/web/mobile apps you&rsquo;ve built (GitHub, demos, or App Store/Play Store links)
 </li>
 <li>
 A brief note on your preferred cross-platform mobile approach
 </li>
 <li>
 A quick summary of what excites you about frontend development and UX
 
 
 
 
 </li>
 </ul>
 We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans. If you would like more information about how your data is processed, please contact us.
 
 
 This is a full-time employment opportunity. We offer a competitive salary and benefits package.

A little about us&hellip;
Knit is building the agentic AI platform that helps enterprise brands run end&#8209;to&#8209;end consumer research. We orchestrate specialized AI agents for surveys, data collection, analysis, and reporting, delivering decision-grade insights to Fortune 1000 brands in hours, not weeks. 
 
In under two years, we&rsquo;ve partnered with 50+ leading enterprise brands, including Amazon, Mars, NASCAR, JBL, ESPN, and Paramount. Knit has grown 500% in the last 12 months and raised $30.6M to date, including a $16.1M Series A in July 2025. Here are example case studies that demonstrate the value of our platform. A product demo can be found here.
Overview
We&rsquo;re building our foundational NYC engineering team from scratch and looking for exceptional builders who are resourceful, deeply technical, and thrive in high-ownership environments. 
 
As one of the first in-house engineers, you&rsquo;ll shape the core of our platform and the culture of a team that will scale to 20+ over the next 18 months. You&rsquo;ll build and orchestrate AI agents, pioneer new UX paradigms, and tackle some of the hardest problems in applied AI with autonomy and end-to-end ownership.

Own 0 1 and 1 N features across the stack, from design docs to building high-throughput data pipelines and scalable FastAPI services.</li><li>
Architect and own the core agent orchestration engine, designing complex, multi&#8209;agent LLM workflows (routing, tool&#8209;use, memory, evaluation) with deterministic fallbacks, guardrails, and auditable actions required by enterprise users.</li><li>
Build AI&#8209;native, human&#8209;in&#8209;the&#8209;loop UIs. Craft React/Next.js interfaces that let users collaborate safely with agents, with transparency and explainability by design.</li><li>
Develop the &quot;factory for the factory&quot;. Build our experimentation platform: CI/CD for prompts and agents, offline/online evals, drift detection, safety layers, and rollout controls.</li><li>
Ship fast, safely. You&rsquo;ll instrument everything for reliability, write concise design docs, add robust tests, and build dashboards and alerts for features you launch.</li><li>
Partner cross&#8209;functionally with Product, AI, Design, CS; talk to customers and SMEs, and turn ambiguous problems into shipped product.</li><li>
Obsess over performance, optimizing for latency across the system: caching, model selection, distillation, batching, vector search, and infrastructure efficiency (GPU/CPU).</li><li>
Operate what you build. This includes on&#8209;call ownership, leading incident response, and driving learning through blameless postmortems.</li></ul><h3 class="jobSectionHeader">

You believe speed and quality aren&rsquo;t opposites and can articulate the tradeoffs you make.</li><li>
You communicate crisply. You share your ideas effectively and thrive in tight feedback loops with product, design, and customers.</li><li>

This role is NOT for you if...</h3><ul><li>
You see a hard line between &quot;frontend,&quot; &quot;backend,&quot; and &quot;product.&quot;</li><li>
