Build and own low-latency, highly scalable backend APIs and data systems for transaction enrichment. Design infrastructure, implement data pipelines, debug production issues, and collaborate cross-functionally to deliver reliable products processing billions of transactions.

Own security for Spade's production edge: manage PKI and mutual-TLS certificate lifecycle, design private network connectivity and webhook delivery security, drive vulnerability remediation, codify secure-build standards, and collaborate across engineering and product to improve overall security posture.

Build and ship end-to-end ML/AI systems (traditional ML, NLP, LLMs/AI agents) on transaction, merchant, and location data. Prototype, productionize, and monitor models, collaborate with engineering and product, and (for senior hires) shape roadmap and mentor teammates.
