Role Overview:
The Customer Love team at Teachstone is focused on driving customer satisfaction and retention by evolving our most widely used products. These products are beloved but need refinement to meet the changing needs of our users. This team sits at the intersection of maintenance and innovation, improving usability and trust while laying the groundwork for a simpler, subscription-based future.

Engineers at Teachstone help define solutions, not just build them. You’ll work closely with Product, Design, and Impact to shape both the problems we tackle and how we solve them. Your work will help users complete tasks more easily, feel more satisfied, and stay engaged.

This role is ideal for someone who is comfortable working across the stack and brings particular strength in building clean, responsive, and maintainable front-end experiences.

What You'll Do:

• Partner with Product and Design to explore customer problems and co-define solutions
• Build and refine features that increase usability, trust, and engagement
• Lead or contribute to front-end improvements that reduce error rates and support successful task completion
• Contribute to back-end changes in Rails that support front-end improvements
• Collaborate across teams (Support, Ops, QA) to validate and prioritize fixes based on real customer pain
• Improve legacy code for better performance, accessibility, and maintainability
• Design with an eye toward platform simplification and long-term subscription enablement
• Write reliable, testable, and well-documented code
• Use modern tools to streamline development and reduce repetitive work

We're Looking For:

• 3+ years of experience as a full-stack or front-end-focused engineer
• Strong proficiency in JavaScript or TypeScript and frameworks like React
• Ability to build clean, responsive, and accessible front-end experiences
• Experience improving or modernizing legacy codebases
• Solid understanding of Ruby on Rails or similar MVC frameworks
• Good judgment about when to fix, refactor, or rebuild, with a pragmatic, user-focused mindset
• Openness to using modern tools, including AI, to improve workflow and code quality
• Ability to diagnose issues across the stack and isolate root causes
• Experience shaping product direction, not just executing delivery
• Interest in improving real-world outcomes through continuous product improvement
• Strong communication skills and a collaborative approach to cross-functional work

Nice to Have:

• Experience in Rails-based systems
• Familiarity with HEART or similar UX metrics
• Background working in sustainment, support engineering, or quality-focused teams
• Familiarity with browser performance tools, accessibility standards, and usability best practices
• Experience building internal tools, workflow automation, or cross-system integrations

Why Join This Team?

• You’ll work on products people already love and help make them even better.
• You’ll contribute to meaningful outcomes in early childhood education.
• You’ll join a small, cross-functional team with shared ownership of both what to build and how to build it.
• You’ll help simplify legacy systems and build more scalable solutions.
• You’ll see the direct impact of your work in metrics that matter to real users.
• You’ll join a team that values trust, focus, and craftsmanship.

Salary Range: $110,000-$127,000 determined by your experience, skills and internal equity.
