Contract: Senior Software Engineer - Newsela Writing Team
Why You'll Love This Role:

We're hiring a Senior Software Engineer Contractor for the Writing product team. This is a hands‑on role on a small, full‑stack team building AI‑powered learning experiences. You'll ship across the product end‑to‑end: frontend, backend, data, and the LLM‑driven services that sit behind our assessment features.

We work AI‑native. Coding agents (Claude Code, Copilot, Cursor) are how this team builds, reviews, and operates, and we expect senior engineers to do more than use them. The strongest people on the team invest in the harness itself: writing skills, hooks, and custom workflows that make the next person faster.

What We're Looking For:
A Senior Individual Contributor with a high agency. Someone who:
- Owns the full lifecycle. Takes a problem from vague ask to shipped, monitored, and stable in production. Comfortable shaping scope without heavy PM guidance.
- Raises issues early. Catches risks, design drift, and brittle patterns before they reach production— in their own work and in review.



Doesn’t wait to be asked.
- Picks up slack outside their lane. Steps into incidents, jumps into a teammate’s PR queue, and drives an unowned problem when priorities shift.
- Builds in the AI‑native space with judgment. Uses agents as a daily driver, knows their failure modes, and pushes the team’s practice forward— not just their own.
- Drives delivery. Active in planning and grooming, pushes back on under-specified work, communicates trade-offs clearly to engineering and product partners.

Core Responsibilities
- Ship full‑stack features with measurable product impact.
- Provide substantive code review, architectural feedback, not just approvals.
- Serve as a first responder for production issues (within working hours): triage, root cause, and preventive measures recommendations.
- Improve the team’s engineering practice over time: tooling, agentic workflows, technical standards, and docume
