Full-Stack Engineer — Document Generation & Report Systems at Blazestack

We're seeking engineers at Senior (L5) to Staff (L6) levels, capable of building and maintaining production-grade document generation systems. You should programmatically create, manipulate, and render Microsoft Word (.docx) and Adobe PDF files at scale using libraries such as Aspose.Words, OpenXML SDK, docx-templater, Apache POI, PDFKit, Puppeteer, iText, wkhtmltopdf, or similar. Deep knowledge of the .docx format (Office Open XML) and PDF internals is essential. Fluency with React, TypeScript, Go, Playwright, GitHub Workflows, and AWS serverless architectures is expected, along with a track record of taking features from design through deployment. You should be comfortable debugging binary formats, managing memory and performance for large documents, and handling image processing in document contexts. Practice test-driven development, write clean, well-factored code, and build intuitive interfaces for real users. A passion for document fidelity and high-stakes software is essential. This is a fast-moving, remote-first environment with a focus on shipping right the first time.
