Implementation review and system design
A remote 2-hour session with a Langfuse engineer and the hiring manager.
Preparation
Read before the session:
- The handbook
- The docs, including the data models for observability, evaluation, and prompt management
Brief
3-4 days prior
You receive a PDF brief for one large feature. Imagine you own it at Langfuse. Think through what we should deliver to customers, how you would build it, and the biggest trade-offs. Then build a POC for the part you find most useful for making those decisions.
We'll set up a Whatsapp group where you can ask questions about the brief, the product, or the requirements.
Session
2 hours
You meet a Langfuse engineer and the hiring manager.
Together, we review your POC and work through the product and technical requirements.
- 30min: review of the POC you prepared.
- 90min: system design for the broader feature, focused on trade-offs behind the biggest product and engineering decisions.
How to succeed
- Read the handbook and the docs before you arrive.
- Own the outcome. Make the trade-offs, and say what you would cut.
- Be direct about what works, what doesn't, and where you are unsure.
