[Hiring] AI-powered Web Application Developer @LetsData

Role Description

We are building a suite of AI-powered web tools and interactive experiences. Full product details will be shared with shortlisted candidates. We need a developer who can own the full stack end to end — from AI API integration and serverless backend logic through to frontend UX, email delivery pipelines, and lead capture flows.

• Building and deploying AI-powered web tools with secure server-side API integration
• Designing and building interactive experiences with branching logic and personalized result screens
• Setting up transactional email pipelines that deliver formatted content or PDFs to subscribers on trigger
• Embedding custom React components within Framer pages and maintaining consistency across mixed hosting environments
• Connecting subscriber data to a CRM or email list tool and ensuring end-to-end capture-to-delivery flows are reliable and measurable

Qualifications

• Familiar with React, JavaScript, Node.js, HTML / CSS, Git / GitHub
• Anthropic Claude API — prompt engineering, structured JSON output, handling streaming responses
• Serverless / edge functions (Vercel, Netlify, or Cloudflare Workers) — API keys must never be exposed client-side
• Basic rate limiting and abuse prevention on public-facing AI endpoints
• Transactional email API — Resend, Mailgun, SendGrid, or Postmark; HTML email templates, deliverability basics, and file attachment handling
• Subscriber list integration — connecting email capture to a CRM or list tool (e.g. Mailchimp, ConvertKit, Loops, or Airtable) via API or webhook
• Programmatic, branded PDF creation from dynamic content using pdf-lib, jsPDF, or a headless browser approach (Puppeteer / Playwright)
• Custom code components and overrides within Framer — understanding its constraints around external scripts, state, and API calls
• Comfortable working across a mixed setup — some pages on Framer, others on Vercel or a standalone host
• Multi-step, branching flows in React with state-managed logic and dynamic result screens based on user input
• Experience designing flows that convert visitors into subscribers

Requirements

• Lightweight database or storage layer — Supabase, Upstash, or Airtable for logging submissions and managing subscriber state
• Background in marketing tech or growth tooling — understanding lead capture, drip sequences, and subscriber segmentation in practice, not just in theory
• Experience shipping polished, conversion-focused web products (not just technical demos!)

How to apply

Please send a short note with links to one or two projects that demonstrate the relevant skills above — something that involves an AI API, an email pipeline, or a lead capture flow. No cover letter needed. Full product details will be shared after an initial conversation.

We are not looking for a generalist who has dabbled with AI wrappers. We want someone who can architect a secure, production-ready flow and has done it before.

Please answer pre-qualification questions.

Note: If you are unable to answer every question in detail, please do not be discouraged! We encourage you to submit your application regardless, as we consider the full scope of a candidate's experience and potential.

Before you submit:

• Check for spelling errors.
• Confirm that your application includes links to one or two projects that demonstrate a secure, production-ready flow involving an AI API, an email pipeline, or a lead capture flow, as requested in the application instructions.

We appreciate you taking the time to provide these details. We will review your responses and be in touch regarding the next steps.
