About the RoleWe’re looking for a Senior Rust Engineer to design, build, and scale the backend systems that power Helius’ developer platform. You’ll work on high-performance, low-latency systems that power the developer Solana ecosystem and process billions of requests per day. This is a high-ownership, high-impact role for someone who thrives on solving hard problems at scale and enjoys working close to the metal. You’ll join a talented, fast-moving engineering team where your contributions will have an immediate impact on our product, customers, and growth.
Design, build, and optimize backend services in Rust with a focus on scalability and ultra low-latency performance.
Own and improve distributed systems powering Helius’ data APIs, event streaming, and RPC services.
Debug, profile, and tune performance in high-scale production environments.
Collaborate cross-functionally with product and frontend teams to integrate features and unblock development.
Establish and maintain monitoring, alerting, and security best practices for the systems you own.
Contribute to the engineering culture through code reviews, technical discussions, and mentoring where needed.
Proficiency with Rust or equivalent is required.
5+ years building and scaling production systems (high-throughput, low-latency, distributed).
Strong understanding of distributed systems and database design.
Ability to work autonomously, move fast, and deliver high-quality code.
Strong communication and collaboration skills in a fast-paced startup environment.
Bonus: Web3 or blockchain experience, familiarity with Solana, or experience building developer platforms.
High-impact work: Your code will power applications used by millions across the Solana ecosystem, including Coinbase, Jupiter, and Phantom.
Cutting-edge tech: Build with React, Next.js, Go, and web3 systems - plus get hands-on exposure to Rust and blockchain infrastructure.
Ownership & growth: Lead critical initiatives, mentor engineers, and influence architecture from day one.
Remote-first flexibility: Work where you’re most productive, with flexible hours and a fully distributed team.
Competitive comp & perks: Market-leading salary, meaningful equity, generous vacation, wellness budgets, and support for learning and travel.
Mission-driven team: Join ambitious builders who move fast, take ownership, and are shaping the future of decentralized apps.
