Senior Backend Engineer m/f/x

At simpleclub, our mission is to create a change in education. Millions of students use our platform every month, and we are building AI-native learning tools that help trainers and educators work smarter and faster: from LLM-powered lesson plan generation to automated assessments and actionable learner insights. As a Senior Backend Engineer, you will own this work end-to-end and directly shape how AI transforms the way people teach and learn.

How will you make an impact:

Own backend features for AI-powered educator tools: architecture, implementation, deployment, observability. The whole lifecycle is yours.

Design and build data ingestion and transformation pipelines. Event sourcing, stream processing, aggregation layers for real-time and batch analytics.

Build and evolve APIs that serve learning insights and AI-generated content. Fast, well-documented, easy to integrate with.

Integrate LLM capabilities into the product: orchestration, structured output parsing, RAG, caching, cost control on model calls.

Use agentic coding tools (Claude Code, Codex, or similar) as part of your daily workflow. Delegate scaffolding, test generation, and first-pass implementations to AI agents. Review, refine, and own what comes out.

Write specs, ADRs, and context docs that work for your teammates and your tooling. Good context engineering speeds up everything downstream.

Ship features with Flutter engineers, PM, and designer. Short cycles, tight feedback loops.

Find ways to automate repetitive engineering work with AI: CI checks, code review triage, doc generation, migration scripts.

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.

Strong Node.js/TypeScript and GCPfundamentals (Firestore, BigQuery, Spanner, Cloud Functions, Pub/Sub).

Experience with both NoSQL and SQL databases. You can reason about data modeling trade-offs, consistency guarantees, and query performance.

You already use AI coding tools daily. Show us your workflow, your prompt patterns, and how you structure context for agents.

Systems thinking. You think about failure modes, scalability, and data consistency up front.

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.

Nice to have, but not a must:

• Experience putting LLMs into production: RAG pipelines, structured extraction, classification, prompt management, eval frameworks.
• Background in ed-tech, learning analytics, or content generation.
• Experience with event-driven architectures and stream processing at scale.
• Infrastructure-as-code (Terraform) and CI/CD pipeline ownership.
• Experience in product trios or similar setups where engineers shape the product, not just build what's specced.
• Hands-on Spanner experience for globally consistent, horizontally scalable workloads.
