Mid-Level Full Stack Developer

Own features end-to-end across DMS, LMS and Active Directory modules — schema to React UI, with a compliance-first mindset.

About the platform

KOŚA is an enterprise-grade, GxP-compliant SaaS platform for the pharmaceutical industry — combining a Document Management System (DMS) and Learning Management System (LMS) on a unified regulated infrastructure. Built to 21 CFR Part 11, EU Annex 11, GAMP 5 and ALCOA++ standards, KOŚA manages SOP lifecycles, GxP training records, electronic signatures and immutable audit trails.

Stack: React 18, TypeScript (strict), Vite, Zustand, Tailwind CSS, Node.js/Express, AWS Lambda, Supabase (PostgreSQL + RLS), AWS (S3, KMS, SES, EKS, CloudWatch, WAF), Redis, GitLab CI/CD, Vercel.

Role overview

We are looking for a mid-level full stack developer with 3–7 years of hands-on experience to own features end-to-end on the KOŚA platform. You will work across the DMS, LMS and Active Directory modules — designing database schemas, building React UIs, writing backend APIs and ensuring all code meets GxP compliance requirements. You are expected to work with minimal supervision, mentor junior team members and contribute to architecture decisions within your domain.
