Senior Product Manager

About the Role

This is a senior product role at Helius - you'll own product across our entire data platform: real-time streaming (LaserStream), historical and archival data, RPC infrastructure, APIs, webhooks, and developer tooling. Our customers are engineers at trading firms, wallets, and data platforms, and the product decisions that matter to them are latency budgets, delivery guarantees, and API ergonomics.

Our best engineers make product decisions, and we expect our PM to return the favor. You should write enough code to use our products the way customers do - prototype an idea, reproduce a bug, contribute when it's the fastest path to shipping. You won't ship production systems, but you should never need someone to show you what our APIs feel like to build against.

The engineering problems are hard: throughput, fan-out, ordering, historical replay. The product problems are harder to see: which guarantees to promise, what a firehose should cost, how to make a powerful primitive easy to adopt. Your job is making the platform coherent without sacrificing performance. You'll be embedded with engineering, in the room on enterprise deals, and constantly in front of customers.

What You'll Do

• Own the product roadmap across the Helius developer platform, balancing customer requests, infrastructure investments, and new product bets

• Spend real time with customers - trading firms, wallets, indexers - understanding their architectures, latency budgets, and where our products fit or fall short
