The Role
We’re looking for a Senior Data & Platform Engineer to build the data and core platform and infrastructure layer that powers our AI systems.

What We’re Looking For
- 7+ years in data engineering, platform engineering, or backend infrastructure - A track record of shipping and owning production systems. - Strong systems thinking (not just pipelines — platform mindset)- Backend system design and API design - Data modeling and relational databases - Performance, reliability, and failure modes
- Proficiency in Golang, SQL, Terraform, AWS - Comfort in a fast-moving startup environment
Bonus
- LLMs / RAG, vector search, fintech or regulated systems - Have startup or early-stage experience.
Why Join
