<div>Description:

The Senior Software Developer / Technical Lead for LibraryIQ is the technical owner of a production SaaS platform used by libraries nationwide. You will be expected to set direction, own outcomes, and lead by example&mdash;while continuing to write production-quality code.
This position is designed for experienced professionals who already operate as technical leaders.

Advanced Angular patterns</li><li>
RxJS at a professional level (not copy/paste observables)</li><li>
Signals and modern Angular architecture</li></ul>
Clean, scalable frontend systems with clear state management

A public GitHub profile with meaningful, non-trivial work</li><li>
Published technical articles or blog posts</li><li>
Conference talks, presentations, or workshops</li><li>

The codebase is more consistent, more readable, and easier to evolve</li><li>
PR quality across the team improves measurably</li><li>
Architectural decisions are documented and understood</li><li>

You are a mid-level developer looking for your first senior or lead title.</li><li>
You have used Angular, but would describe yourself as &ldquo;comfortable&rdquo; rather than expert.</li><li>

You have not yet been responsible for the long-term health of a production codebase.</li><li>
You prefer to focus only on tickets and avoid architectural discussions or decisions.</li><li>
You expect a dedicated architect or tech lead to make hard technical calls for you.</li><li>
You are uncomfortable pushing back on Product or peers when the technical answer requires it.</li><li>
You dislike code reviews, or see them as a formality rather than a core responsibility.</li><li>
You want to stop writing code in order to &ldquo;move into leadership.&rdquo;</li><li>
You need detailed implementation instructions to be productive.</li><li>
You are not comfortable being accountable for technical outcomes&mdash;not just effort.</li><li>
This is not a role for someone who wants to become a technical leader.</li><li>
It is for someone who already is one.</li></ul>
