Senior Backend Engineer m/f/x (Remote)

Department: Engineering

Employment Type: Full Time

Location: Remote, Remote

• 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).

• 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.

What is in for you:

• Unlimited paid holidays
• Work from anywhere
• Team events
• A great culture
• Perk Budget
• Join a purposeful mission
