Zusammenfassung

Enery is seeking a Senior Fullstack Developer / Tech Lead in Vienna to build the internal platform’s application layer with ownership from data model to UI. You’ll guide a small IT and Data team, defining services, authentication, and dashboards, and you’ll ensure smooth production with strong incident handling.

You will work across Python-based backend and React/TypeScript frontend, leverage Snowflake/dbt, and shape platform decisions while collaborating with an international team.

Qualifikationen

• 6+ years of professional full-stack experience shipping web applications used by internal or external customers, at least 2 of them in a senior or lead role.
• Experience operating production systems under an availability commitment — you have carried an SLA, run incident response, and written the post-mortem.
• Strong Python, including web application work — Streamlit, FastAPI, Django or similar.
• Comfortable building and operating long-running services, not just request-response endpoints.
• Professional experience in at least one language beyond Python.
• Working knowledge of relational databases and SQL; comfortable reading and writing performance-sensitive queries.
• Hands-on experience with a cloud provider (AWS preferred; GCP or Azure acceptable) and with CI/CD tooling (GitHub Actions or equivalent).
• Product judgement — willing to say "this is enough for the first release" and defer the rest, willing to argue for more when it matters.
• Fluent English C1

Aufgaben

• Build the shared foundations of the platform — authentication, navigation, access control — and the business-facing pages on top of them (monitoring, forecasting and reporting tools)
• Ship features end-to-end: define the data model in Snowflake, wire the backend, build the UI, take it to production
• Own the frontend on the modules you build, working alongside our existing dashboard engineer
• Set up and maintain the CI/CD pipeline that every future platform module will deploy through
• Take technical responsibility for the platform in production — availability targets, incident response, and the post-incident work that keeps the same fault from returning
• Contribute to platform decisions: authentication, access control, service boundaries, developer experience
• Pair with a senior backend engineer joining the team on shared services (identity, logging, integrations)
