Summary

The Senior Full Stack Engineer designs, builds and ships software across Learnosity's Build product, our cloud-based API toolkit that educational companies use to create interactive and accessible assessment experiences at scale.

This role sits within Technology - Build and works across the full stack: JavaScript, React and CSS on the front end, and PHP, Python, Postgres/MySQL, Elasticsearch and AWS on the back end. You will own work from early design through to release, working closely with product, design and senior leadership to turn roadmap goals into software customers use.

This role helps the team ship faster without lowering quality. You will lead complex projects end to end, raise the standard of design and code through review and mentoring, and use AI tools to speed up delivery.

Key Responsibilities

• Own the design and delivery of maintainable, well-engineered software across the Build product, balancing immediate needs with long-term technical health
• Lead task planning, estimation and scheduling, and keep documentation current throughout
• Translate product and business goals into clear engineering solutions, proving out complex functionality with real data before release
• Find the root cause of complex issues and deliver permanent fixes, spotting risks before they become problems
• Mentor less experienced engineers and raise the quality of design and delivery across the team
• Work with engineering, product and design to align on shared goals and keep delivery on track
• Use AI tools and introduce new technologies where they help the team deliver faster
