: Our client is looking for a senior full-stack engineer who can take product vision and turn it into production-ready software.

You'll work directly with our product lead and CTO to translate product concepts, requirements, and designs into features that ship. You'll own development across the stack, from React interfaces and TypeScript APIs to PostgreSQL, AWS infrastructure, and data workflows.

This is a hands-on role for someone who likes building, solving technical problems, and taking ownership from idea through production. You'll have room to bring your own ideas and technical judgment, while working from a clear product vision and roadmap.

What you'll do:

- Build our reporting and analytics product: CSV ingestion, analytical SQL, and dashboards, including migrating existing reporting logic from SQL Server to PostgreSQL
- Ship features end to end: React UI, TypeScript/Node APIs, and PostgreSQL, built from approved design mockups
- Own backend and infrastructure changes (schema migrations, row-level security, Lambda/SQS workers, AWS CDK, IAM), with CTO sign-off on architecture
- Keep CI/CD healthy (GitHub Actions), and write tests and clear PR descriptions for everything you ship

Must have:

- 5+ years of production TypeScript across React and Node, including building and integrating REST APIs (OAuth, rate limits, retries, webhooks)
- Strong PostgreSQL: schema design, migrations, and analytical SQL (window functions, materialized views, query tuning), plus experience building data-heavy UIs and dashboards
- Hands-on AWS serverless experience: Lambda, SQS, S3/CloudFront, and infrastructure as code (CDK preferred)
- Clear written English, and comfort working in small, reviewable pull requests

Nice to have:

- T-SQL / SQL Server experience, especially porting reporting logic to PostgreSQL
- AWS Bedrock or other production LLM integrations
- Microsoft Entra ID / Microsoft 365 APIs
- Early-stage startup experience
