PM interview at Paxos with a scenario-based question about handling client expectations on the fly. Short and focused, just the one question from what I remember.

A potential client is asking you to guarantee a delivery date for a feature your team has never discussed. How do you handle it?

“This one tripped me up more than I expected.”

Interviewed for a bizops role at Paxos. One question on stablecoins and where they fit in the broader blockchain landscape. Short post, not much else to go on.

Within the blockchain industry, where do you see stablecoins having the greatest potential?

“This is the kind of question that sounds open-ended but really wants you to have a take.”

Paxos·Software Engineer·Onsite - System Design / Architecture

Apr 2026

System design round at Paxos for a software engineering role, centered on a market surveillance platform with some tricky routing and scalability constraints. The PM framing threw me a little but the core problem was pure distributed systems.

Design a market surveillance platform for financial exchanges that ingests trading orders and detects potential market manipulation, supporting two separate detection algorithm types: one that must process all orders from a given trader on the same instance, and another that routes all orders from a given exchange to a single dedicated instance. Each algorithm type can be independently scaled, and the system must handle very high throughput with strong availability.

“This one took me a minute to untangle.”

Apr 2026

System design round at Paxos for a software engineering role, focused entirely on building a market surveillance platform for financial exchanges. Pretty intense scope for a single session, covering everything from ingestion to customer-facing event delivery.

Design an end-to-end market surveillance platform for financial exchanges that ingests trading orders, routes them to detection algorithms based on trader or exchange identity, and surfaces suspected manipulation events to customers.

“This is a meaty one.”
