The Role
Own backend features and architecture for AI-powered educator tools and API-driven learning content. Lead technical designs, migrations, deployments, observability, and event-driven integrations while improving AI-assisted engineering workflows. Collaborate closely with Flutter engineers, product managers, and designers to deliver scalable, secure, high-performance services. Work across Firestore, PostgreSQL, Spanner, permissions, simulations, CMS modernization, and education integrations.
Summary Generated by Built In
At simpleclub, we’re on a mission to shape the future of learning for millions of students. As part of this mission, we’re undertaking an ambitious and rewarding project: migrating our custom CMS (built on Firestore and trigger-based pipelines) to a modern, API-first headless CMS.
We’re looking for a Senior Backend Engineer to join our team focused on training material and learning experience, further developing a core domain responsible for delivering and managing all our app content. We’ve got tricky and impactful projects lined up: you’ll be laying the foundation for future-proof, AI ready API-driven content delivery.

We’ve got tricky and impactful projects lined up: you’ll be laying the foundation for future-proof, AI ready API-driven content delivery.
🚀 Upcoming projects
- Simulations: integrate internally produced 3D simulations and mini-apps deeply with our core app features (progress, learning plans, tests)
- Permissions: with more and larger customers, we want to deeply integrate our SpiceDB backend permission system
- Unified CMS: producing content in-house compared to our content creator available for customers is deviating, and we want everyone to benefit from the work going into it
- Integrations: allow different education providers to sync and benefit from the simpleclub platform via connections like SCORM/LTI
How will you make an impact:
- Own backend features for AI-powered educator tools: architecture, implementation, deployment, observability. The whole lifecycle is yours.
- Lead technical designs and ADRs for new and refactoring projects, ensuring stable, secure and fast time to customer value
- Integrate further, experiment with and continually improve how we work with AI (create and manage skills, loops and context files), in the context of the above projects.
- Use agentic coding tools to refine, plan, first draft and monitor as part of your daily workflow.
- Ship features with Flutter engineers, PM, and designer. Short cycles, tight feedback loops.
What we value:
- 7+ years of backend development on production systems. You've owned services, debugged incidents at scale, mentored engineers, and made architecture decisions you had to live with.
- Experience in product trios or similar setups where engineers shape the product, not just build what's specced.
- You use AI coding tools daily. Show us your workflow, skills, context management and agent orchestration, and how you leverage them responsibly.
- Strong experience with NoSQL (Firestore) and relational databases (PostgreSQL/Spanner) especially schema migration and transformation tasks.
- Understanding of API design, caching, and high-performance content delivery.
- Clear, async-first communication. You write well, share context without being asked, and document decisions. We're a remote-first, multinational team. English is the working language.
- Comfortable with asynchronous, event-driven systems (e.g., via Pub/Sub or webhooks).
How you'll get started quickly
- Team culture: we support and give feedback to each other. We’ll ensure you’re onboarded properly and have everything you need.
- High autonomy: You’ll be trusted to own your technical solutions while being supported by an experienced engineering lead.
- Remote-first culture: We’re async-friendly, collaborative, and focused on deep work without constant meetings.
Tech Stack You’ll Work With: Node.js, TypeScript, Claude, Terraform, GCP (Firestore, Spanner)
What is in for you:
- Unlimited paid holidays
- Work from anywhere
- Team events
- A great culture
- Perk Budget
- Join a purposeful mission
