• Design and execute queries against PostgreSQL; collaborate on schema design and migrations for new UI features.
• Partner with product management and development engineers to translate monitoring/management workflows into intuitive UIs.
• Profile and troubleshoot web UI to identify bottlenecks and inefficiencies.
• Collaborate with QA, DevOps, and product teams to ensure robust feature delivery.
• Participate in code reviews and contribute to continuous improvement of code quality and architecture.
• Support ongoing code maintenance, refactoring, and technical debt reduction.

About You:

• TypeScript & Components: Solid experience with TypeScript; component‑based development using Stencil (or similar web component frameworks).
• Back-End Web: Proficiency with Node.js and ExpressJS for building RESTful/streaming endpoints; understanding of middleware, routing, and error handling.
• CGI & Scripting: Comfortable reading/writing Perl or Python CGI scripts, form handlers, and templating in server‑rendered flows.
• Web Server Ops: Practical experience configuring Nginx (reverse proxy, caching, compression, HTTP/2/3, TLS, upstreams).
• Databases: Working knowledge of PostgreSQL (schemas, indexing, joins, migrations, performance basics).
• Containers: Experience building and running services in Docker, composing multi‑container environments.
• Testing & Tooling: Familiarity with Playwright or similar; linting, formatting, and CI (e.g. Jenkins, GitHub Actions, GitLab CI).
• Security & Performance: Understanding of CSP, CORS, CSRF, XSS mitigation; profiling and performance optimization for production UIs.
• Collaboration: Version control with Git, code reviews, and clear technical communication.
• Strong communication skills and ability to work effectively in Agile teams.

The following experience is considered an asset:

• Real‑time/Streaming UI: SSE/WebSockets experience; visualization of telemetry or alarms.
• Streaming media: video playback in the browser.
