Description:

Role summary Own cloud deployment, backend/frontend engineering, web UX adaptation, and production operations for an OEM cloud and React web portal integrated with the IoT platform. You take a delivered baseline, ship it to staging/production, adapt the UI for the market, and keep the stack running - including code and infrastructure changes when platform or product needs require it. Responsibilities Cloud & operations (~40%) - Deploy and maintain staging and production on AWS (containers, CI/CD, secrets, Firebase). - Wire and operate integrations with DCF, CPS, MSF/KMS, CDP event workers. - Promote releases with rollback; keep environment matrices isolated. - Monitor APIs, workers, certs; handle incidents; apply security patches. - Maintain runbooks and monthly ops reporting. Backend & integration engineering (~35%) - Implement and maintain Node.js / Express API changes (bugs, security, small features, API contract alignment). - Adapt integrations when IoT services or SDKs change. - Own production blockers: auth/JWT, logging, CI gates, config externalization. - PostgreSQL / Redis / S3 as used by the stack; review and take code ownership after handover. Frontend / UX (~25%) - Adapt React + Vite SPA: branding, English copy, theme/config. - Align menus and screens with platform role specifications (phased by product priority). - Enforce UX safety rules (e.g. no remote actuation from web where prohibited). - Fix web defects from UAT; smoke-test critical flows before releases. Must-have skills - Node.js / Express APIs and React SPAs (Vite or equivalent). - AWS, containers, CI/CD (e.g. GitHub Actions); secrets and env management. - PostgreSQL; comfort with Redis and object storage. - Shipping production code changes (not only operating systems). - Incident response; clear written English. - Working with external delivery partners and shared Git repositories. Nice to have - IoT / device cloud (certs, webhooks, KMS, CoAP/HTTP gateways). - Firebase Auth; API and E2E automated tests. - Kubernetes / Helm or equivalent.
