Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Staff Software Engineer - **Company:** Helius, LLC - **Location:** United States (Remote available) - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Application Programming Interfaces (APIs), C++ (Programming Language), Distributed Data Store, Distributed Systems, Open Source Technology, Blockchain, Data Streaming, System Programming, Backend - **Published:** September 4, 2026 - **Apply:** https://startup.jobs/staff-software-engineer-backend-helius-9489140 ## About the Role * 8+ years of backend engineering with a strong track record building large-scale, production-grade systems * Deep systems-level expertise - you operate comfortably at the layer where software meets hardware * Proficiency in Rust (strongly preferred) or equivalent systems programming language (C++, Go) * Demonstrated ability to own and evolve complex systems end-to-end, from architecture to production operations * Experience leading ambiguous, cross-team technical initiatives and driving them to completion * Performance engineering instincts - you've profiled hot paths, understood the root cause, and fixed it at the code level * High ownership, high intensity - you thrive in fast-moving environments and hold yourself to an exceptional standard * Prior exposure to engineering cultures that prioritize operational excellence, performance, and customer reliability at scale, * Deep expertise in one or more of: distributed storage, streaming infrastructure, edge networking, or query engines * Experience building or operating systems at petabyte scale or microsecond latency budgets * On-call ownership of mission-critical production services * Interest in Solana, blockchain infrastructure, or real-time financial systems * Open source contributions or technical writing that demonstrates depth * Mix of large and small company experience strongly preferred - you've built the habits and can operate at both speeds ## Description We're looking for a Staff Backend Engineer to take ownership of one of our core systems - Gatekeeper, Data Streaming, Historical APIs, or Account Index. These are the foundational layers of Helius's infrastructure, operating at the intersection of extreme performance requirements and real-world scale. Each system sits in the critical path of the Solana ecosystem. At this level, you're not just building - you're setting technical direction, making architectural decisions that shape the platform for years, and raising the bar for everyone around you. You'll work directly with founders and engineering leadership to define what we build and how we build it. Small team, enormous scope, and the expectation that you'll own your domain end-to-end., * Own the technical direction for a core backend system - architecture, reliability, performance, and roadmap * Design and implement solutions to the hardest problems in your domain - distributed systems, storage engines, streaming pipelines, or edge infrastructure * Drive performance engineering across your system - profiling, benchmarking, and pushing latency and throughput to the limit * Set standards for operational excellence - observability, incident response, and making systems simpler and safer to operate * Partner with founders and engineering leadership on long-term technical strategy * Mentor senior and mid-level engineers, drive technical consensus, and influence without authority * Identify and solve complex, ambiguous problems that span multiple systems ## Related Videos - [Python-Based Data Streaming Pipelines Within Minutes](https://www.wearedevelopers.com/videos/1233-python-based-data-streaming-pipelines-within-minutes) - [Pragmatic Blockchain Design Patterns: Integrating Blockchain into Business Processes](https://www.wearedevelopers.com/videos/1579-pragmatic-blockchain-design-patterns-integrating-blockchain-into-business-processes) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [How building an industry DBMS differs from building a research one](https://www.wearedevelopers.com/videos/768-how-building-an-industry-dbms-differs-from-building-a-research-one) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [The Best X (Twitter) Accounts for Developers](https://www.wearedevelopers.com/magazine/294-the-best-x-twitter-accounts-for-developers)
