Crimson Global Academy (CGA) is a world-class online school delivering live, real-time learning to ambitious students around the world. With over 1000 students joining us from 65 countries, our vision is to unlock our students' limitless potential, together, for extraordinary futures. The Role Our engineering team builds the systems that make a global virtual school actually work: the student and parent app and backend (CGA Home), internal sales and marketing tools, school operations infrastructure, and the public website. Our engineers sit close to the product, close to the people using it, and close to the impact. We're looking for a senior engineer who's genuinely excited by the difference good software makes to a child's education, and who's ready to help us raise the bar on what we ship and how we ship it. You'll work at a senior level across our backend and infrastructure, contribute to architectural decisions, and help shape the technical direction and engineering culture of the team. What you'll do Design and build CGA's products in the cloud, backend, infrastructure, and frontend where needed Take ownership of hard technical problems end to end, from framing through to shipping, monitoring, and iterating Test-drive your development so that once your work is done, it doesn't go backwards Contribute to architectural decisions and help shape CGA's technical direction Partner with Product Managers and stakeholders: give honest estimates, communicate clearly, and ship when you said you would Follow and improve our CI/CD, testing, and deployment practice so the team ships faster and more safely Monitor product health and respond when something needs attention Mentor your colleagues, lift quality across the team, and model the standards we hold each other to What we're looking for Essential 5+ years of professional software engineering experience Strong full-stack instincts with deep backend and infrastructure experience at a senior level Fluency (or close to it) in our stack: HTML5/CSS, React, TypeScript, Node, Postgres, Docker, AWS, Terraform A track record of shipping software you and your team are proud of in a strong CI/CD environment Clear, honest communication and a team-first instinct, you back your teammates and deliver what you've committed to Genuine interest in growing into technical leadership over time Personal commitment to CGA's standards: unlocking potential together, rethinking and rebuilding, and raising the bar to compound impact Highly regarded Experience building education or other consumer-facing products with a global user base Experience mentoring or guiding more junior engineers Comfort running production systems across multiple regions and time zones Why CGA Every family that chooses CGA is trusting us with something irreplaceable. Engineering owns the platforms that make CGA possible: the code you ship reaches students and families around the world, every day. If you want senior-level work with real impact, on a team that holds itself to a high bar, we'd love to hear from you.
