Staff Backend Engineer, Data Streaming

Helius

6d • Remote

About The Position

We're looking for a Staff Engineer to own and evolve our streaming infrastructure and products. This isn't a role where you execute someone else's roadmap — you'll define technical direction, drive architectural decisions, and solve the hardest problems on one of Helius's most critical and fastest-growing products. You'll work closely with engineers and founders to shape what we build and how we build it.
The Data Streaming team builds and operates products like Laserstream that deliver real-time Solana state changes to thousands of developers and institutions around the world. Latency, reliability, and throughput aren't just engineering concerns here, they're the product. The team moves fast, owns a large surface area, and sits in the critical path of the company's growth.

Requirements

• 8+ years of backend engineering experience with a strong track record building large-scale, production systems
• Deep proficiency in Rust or an equivalent systems programming language
• Performance-oriented engineering instincts — you think across the full stack: software, Linux internals, networking, and hardware
• Hands-on experience with streaming systems such as Kafka, NATS, Flink, or Kinesis
• Proficiency operating databases in production environments (Postgres, ClickHouse, RocksDB, or similar)
• Strong operational mindset — you've owned production systems with real customers and know what it takes to keep them running reliably
• Excellent communication and writing skills; you can drive technical consensus and influence without authority
• High ownership and urgency — you thrive in fast-moving environments and hold yourself to an exceptional standard

Responsibilities

• Architect and lead development of high-throughput, low-latency streaming systems that power our core products
• Drive the technical roadmap for streaming — including filtered streams, next-generation webhooks, and new capabilities that expand what developers can build on Solana
• Lead system design discussions and make architectural decisions across the stack: software, hardware, and networking
• Set standards for operational excellence — reliability, incident response, and system observability
• Mentor and elevate engineers on the team, and drive technical consensus across engineering, product, and leadership
• Partner cross-functionally with Sales, Support, and adjacent infrastructure teams to ensure streaming products meet the needs of customers at scale
• Identify and solve complex, ambiguous problems that span multiple systems

Benefits

• Remote-first flexibility
• Competitive comp & perks: Market-leading salary, meaningful equity, generous vacation, wellness budgets, and support for learning and travel.
