Job description

You will build our own CRM product, the one already running a four-brand visa and travel group out of a single inbox: unified conversations with per-brand tags, needs-reply and gone-quiet queues, AI-drafted replies, contacts, cases, pipeline, payments and job applications. It has real users on it today, so every change you make lands on people who will tell you within the hour whether it helped.

Responsibilities

• Design and build CRM modules end to end: inbox, contacts, cases, pipeline, payments and knowledge base.
• Model the data properly in Postgres and keep migrations clean as the product grows.
• Integrate email, payment gateways and third-party APIs so they survive retries, duplicates and webhook chaos.
• Tune the AI layer: prompts, retrieval over the knowledge base, and the guardrails around drafted replies.
• Handle auth, roles and multi-brand isolation so one brand's inbox never leaks into another's.

Requirements

• 3 to 6 years of full-stack work, equally comfortable on the schema and on the screen.
• Strong TypeScript and real SQL: joins, indexes, and a theory for why a query got slow.
• You have shipped features into a product that had live users on it while you were changing it.
• Experience with an ORM and versioned migrations; we use Drizzle, but Prisma or TypeORM background transfers fine.
• You can explain a technical trade-off to a non-technical stakeholder in one paragraph.
