About The Company
Granton Hale Capital is part of a financial services group with operations across investment banking, business lending, and large-scale technology infrastructure. We operate across multiple countries and are building internal tools to support our growth.
About The Role
We need one developer to build our entire internal tool stack. You won’t be writing CRUD endpoints for someone else’s Saa S product. You’ll be the sole developer building a platform that powers real business operations at serious scale — millions of emails, millions of contacts, hundreds of thousands of accounts. Full autonomy. No committees. No sprint planning. You get specs, you build, you ship. Every tool you complete goes straight into production after it’s proven to work. There’s a backlog of 10+ projects. If you deliver, there are years of continuous work. We provide Claude Pro, Codex or Cursor Pro, and fast decisions. $750 – $1,000 USD/month depending on experience and output, paid monthly.
What You’ll Build Email verification engine — MX lookup, SMTP handshake, catch‑all detection, proxy rotation, anti‑detection, built to verify millions of addresses
Google Maps scraper — large‑scale structured extraction (business name, address, phone, email, category, reviews) with anti‑detection
Cold email sequencing platform — managing sends across hundreds of thousands of connected email accounts (Outlook/Google APIs), 1 M+ daily volume, random scheduling for deliverability, IMAP reply detection, webhook integrations, campaign management dashboard
Self‑hosted SMTP Inboxes
Linked In open profile scraper — bulk extraction of public profile data
Linked In automation tool — connection requests, messaging sequences, profile visits at scale
Apollo scraper — contact and company data extraction at volume
Internal enrichment and workflow engine — webhook in, verify, enrich, personalise with AI, push to sending infrastructure (our replacement for Clay)
Contact database platform — millions of records, searchable, deduplicated, with API access
Unified API layer — connecting all internal tools into one system What We’re Looking For
Someone who solves problems, not someone who reports them. If an IP gets blocked, you implement rotation and move on. If a scraper breaks, you fix it before we notice.
Required Strong Node.js and/or Python
Postgre SQL at scale (millions of rows, proper indexing)
Redis + job queues (Bull MQ, Celery, or similar)
Puppeteer / Playwright — headless browser automation, anti‑detection, proxy management
REST API development
Next.js / React for dashboards
SMTP / IMAP protocol knowledge, DNS (SPF/DKIM/DMARC)
Comfortable deploying on Linux / VPS
Uses AI coding tools daily (Claude Code, Cursor, Copilot) Nice To Have Built email verification or deliverability systems before
Linked In scraping / automation experience
High‑throughput architecture (horizontal scaling, worker pools) Compensation And Benefits $750 – $1,000 USD/month depending on experience and output, paid monthly
Claude Pro and Cursor Pro provided — we expect you to use AI tools to move faster
Continuous work — this isn’t a 3‑month contract. The backlog is deep and growing. The right person has years of projects ahead.
Full autonomy — no standups, no sprint ceremonies, no Jira tickets. You get specs, you deliver. You communicate fast and proactively.
Fast feedback — decisions come from one person, not a committee. No waiting around.
