Company mission
Memrise's mission is to turn learning into a recreational activity.
Role
Who you are
- Prompt-engineering best practices
- Proactiveness & strong ownership mindset
- Retrieval-Augmented Generation (RAG)
Desirable
- Recommender-systems foundations
- A/B testing at scale
- Python (LLM tooling) & Kotlin fundamentals
- ML-ops tooling (Airflow, Feature Store)
- Basic statistics / experimentation design
What the job involves
- Prompt & RAG Engineering
- Design, tune, and A/B-test prompt chains that lift instruction-following accuracy, session-completion detection, and overall Buddy engagement. Implement RAG pipelines to power both support bots and in-product answers
- Multi-language Scale-out
- Modularise Buddy prompt chains so every language pair uses a single, well-structured template with language-specific slots. Add capabilities to compare model performance for different languages
- Recommendations Engine
- Prototype and productionise a Kotlin- or Python-based service that recommends the next best learning feature, measuring success via lift in feature completions and balanced usage
- Evaluation & Observability
- Build an end-to-end prompt-quality harness (unit + offline + in-prod metrics) and integrate it with our custom model-serving layer
- Collaboration & Ownership
- Partner daily with Sonia (Head of Content), Luis (Dir. Product Strategy & Innovation) and Elizaveta (Engineering Manager), proactively taking ownership of high-leverage deliverables that move the KPIs
Salary benchmarks
Our take
Memrise's USP is that their content adapts to users’ needs as they progress through their lessons. They were originally a general learning platform but saw the importance of focus, so narrowed down to languages.
They have built the service to work well on desktop and mobile, which is another differentiator that has enabled them to build a loyal customer base. Apple showed off Memrise during a WWDC event, helping create publicity for the product.
