Remote Fullstack Engineer AI Experience

Tóm tắt công việc
An AI-native platform that lets Swiss fiduciary firms manage client bookkeeping, payroll and compliance through a WhatsApp-first workflow, backed by a [protected info] application and n8n automation. We're hiring a backend-leaning full-stack engineer to close a critical security backlog, stabilise the platform for production use, and lay the operational groundwork, CI/CD, observability, staging are needed to onboard more customers safely. You will work directly inside the existing single-contributor codebase, take full ownership of the n8n automation layer, and be one of two engineering hires driving the technical roadmap (the other being an AI/Agent Engineer).
Responsibilities
Remediate the platform's active security exposure: enforce authentication and row-level security (RLS) on every API route; close public database policies exposing payroll and client data; fix a tenant-isolation bug that allows cross-tenant access
Replace n8n's direct database master-key access with an authenticated ingestion API that derives tenant identity server-side, removing the single largest operational risk in the automation layer
Design and implement a background job queue for heavy, currently synchronous document processing (PDF/XLSX extraction, multi-account imports) to remove request-timeout failures
Make cloud storage private (signed URLs, UUID paths) and put the database schema into version control, paired with a real staging environment
Build CI/CD pipelines, automated tests, including tenant-isolation regression tests and baseline observability (logging, monitoring, alerting)
Harden and maintain the n8n workflows that run the WhatsApp document-intake and accounting-automation flows, including error handling, idempotency, and a dead-letter/retry path
Implement data-subject-rights tooling (export/erase) and an append-only accounting ledger with reversal entries, in coordination with the company's external data-protection advisor
Redact personal data from application logs and enforce least-privilege access patterns throughout the stack
Collaborate with the AI/Agent Engineer on backend integration points for the LLM-driven agent, tool authorization checks, audit logging of agent actions.
