We are looking for 2-3 AI engineers/developers to help us build/complete an AI go-to-market (GTM) tool that looks at both structured and unstructured data, runs it all through our AI engine, and provides insights and recommendations straight to sales people. The tool is able to handle large volumes of data and provide actionable insights for business decision-making. Our engine consists of a prioritization algorithm, pattern matching and sentiment analysis. We use our recommendation engine to deliver the output (insights) straight to our tool which is "Apple-simple", intuitive and gamified. No more sales time wasted on looking at dashboards and trying to agree on which insights are important and which should be acted on. What you'll do Own features end-to-end across theFastAPI backend (IEngine) and Next.js 15 / React 19 frontend— from Claude prompt design to UI polish. Extend the intelligence pipeline: meeting ingestion (Google Drive + Deepgram realtime), Claude-driven action card generation, Neo4j relationship graph, and Supabase-backed state. Build customer-facing dashboard surfaces — deals, gamification, coaching, trust graph — with TypeScript, Tailwind, shadcn/ui, and D3. Operate WebSocket transcription sessions and async job pipelines reliably under real meeting load. Instrument with Sentry, harden auth (NextAuth :left_right_arrow: JWT :left_right_arrow: FastAPI service-to-service), and keep deploy pipelines green. Build with simulators: when you can't test against live meetings, generate realistic synthetic transcripts through our simulator service. Stack you'll work in Backend: Python 3.11, FastAPI, Uvicorn, PyJWT, Anthropic SDK, Deepgram, Neo4j, Supabase (Postgres + realtime), WebSockets Frontend: TypeScript, Next.js 15 (App Router), React 19, NextAuth 5, Tailwind, shadcn/ui, D3, Stripe Infra: Fly.io, GitHub Actions, Sentry, Supabase AI: Claude (Opus/Sonnet) for transcript analysis, action card generation, and agentic dev workflows What we're looking for 4+ years building production web applications, ideally across Python and TypeScript. Comfort designing and shipping features against an LLM API — prompt iteration, structured outputs, evals, cost/latency tradeoffs. Real Claude or OpenAI production experience required. Experience with multi-tenant SaaS patterns, JWT auth, and one or more of: graph databases, realtime systems, audio/transcription pipelines. Comfort with AI-assisted development workflows (Claude Code, Cursor, etc.) — not just as a code-completion tool, but as a way to plan and ship features. Bias toward shipping. Small surface area, high ownership, no committee.

Senior React Native Engineer — Take Over & Launch a Consumer Social App We're looking for a senior React Native engineer to take ownership of an existing, fully-built consumer social media app and get it to App Store launch quality. The app already works. A previous developer built it end to end, and we have a complete, functioning codebase. What we need now is an experienced engineer to take the wheel, harden it, and ship it: tighten the design, fix the speed, clean up the backend, eliminate bugs, and make every feature work exactly as intended. This is a polish-and-launch role, not a build-from-scratch role, so we want someone genuinely strong at improving an existing codebase rather than rewriting it. This is a video-first social product — an infinite media feed, video upload and playback, user profiles, direct messaging, notifications, and engagement/retention mechanics. Think of the surface area of a modern social app, and our bar is that it should feel as smooth and fast as the top social apps on the store. Right now it's close, and we need someone to take it the last mile. What you'll own Performance & smoothness — profile and fix slow screens, janky scrolling, slow cold starts, memory issues, and re-render problems. Feed and video playback in particular must be flawless. Design polish — tighten spacing, animations, transitions, and component consistency so the UI looks and feels professionally finished. Backend cleanup — review and improve the backend: data models, queries, API/edge functions, security rules, storage, and the media pipeline. Efficient, reliable, and ready for real users. Bug elimination — hunt down and fix every bug; deliver a stable, well-tested app. Feature completeness — make sure all existing features work as envisioned, end to end, with proper edge-case and error handling. App Store launch — get it through Apple App Store review: build config, signing, App Store Connect, privacy/permissions, store technical requirements. (Android is a likely follow-on.) The stack you'll be working in Frontend: Expo + React Native + TypeScript, Expo Router (Reanimated and EAS Build/Submit a plus) Backend: a managed cloud backend with Postgres, authentication, file/object storage, realtime subscriptions, and row-level security (BaaS-style; comfortable with SQL, policies, and serverless/edge functions) Video: a managed video pipeline for direct uploads, transcoding, and adaptive HLS streaming, plus object storage and CDN delivery Notifications: push notifications (OneSignal or similar) Payments: Stripe integration experience is a plus Native device APIs: comfort with camera, media library, background tasks, location, and notifications; able to write/maintain native modules when needed Tooling: Git, EAS, environment management, basic CI/CD, crash/error monitoring (e.g., Sentry) Must-haves 4+ years building production React Native apps, with shipped App Store apps you can show us Deep, demonstrable experience profiling and optimizing React Native performance (list/image/video tuning, memoization, startup and bundle optimization) Strong with a Postgres / BaaS-style backend (schema design, SQL, security rules, serverless functions) Real experience with video upload and playback Have taken an app through Apple App Store review to a live release Excellent written English, proactive communication, and comfort owning a codebase someone else wrote Nice-to-haves Realtime/social feed and messaging at scale, Reanimated/gesture-heavy UI, Stripe or marketplace payment flows, crash analytics and feature flags, and prior experience launching a consumer/social app. How we work Small, fast-moving founding team with direct access to the founder and quick decisions. We'll start with a short paid trial task so we can both confirm fit before committing to ongoing work; strong performers move into an ongoing, long-term engagement. Some overlap with US Central time is required. An NDA is required before code access. To apply, please include: Links to 1–3 App Store apps you've built and your exact role on each A time you made an existing React Native app dramatically faster or smoother — what was slow, what you did, and the measured result Your experience with video upload/playback and with a Postgres/BaaS backend Your weekly availability and your US-Central overlap Start your reply with the word "SMOOTH" so we know you read this. Generic proposals will be ignored.
