- Develop and optimize PostgreSQL schemas, SQL queries, indexes, migrations, and data workflows.
- Deliver end-to-end product features using Node.js, TypeScript/JavaScript, PostgreSQL, and Angular.
- Troubleshoot production issues using logs, metrics, traces, and database execution plans.
- Work independently from Jira ticket → development → testing → QA → production.
- Use AI coding tools responsibly while maintaining strong engineering and code-quality standards.

Must Have:

- 5 years of senior-level software engineering experience.
- Proven experience shipping at least one LLM/AI feature to real users.

- Strong PostgreSQL & SQL — query optimization, indexing, transactions, migrations, and data integrity.
- Experience with a modern frontend framework — Angular preferred; React/Vue considered.
- Experience building and operating production web applications.
