Rust Jobs in Web3

Senior Rust Engineer (Remote) 

$7,000/month (paid in USDT on Ethereum) 

Remote-first | Full-time | Quarterly off-sites

About Guardis

Guardis is a Web3 security company focused on protecting the Solana ecosystem. We stream raw block data in real time, use AI to enrich it, and surface scam behaviour before it spreads. Our platform already outperforms anything else when it comes to spotting sketchy liquidity, deployer patterns, and social manipulation.
 
With a huge rise in scams and a big drop in active Solana users this year, our work matters more than ever. We are now looking for a Senior Rust Engineer who can build fast, reliable systems and help traders stay one step ahead.
 

Why this role is important

Solana regularly pushes out more than a billion transactions each month. To handle that load, our backend needs to be fast, efficient, and absolutely solid. We are looking for someone who can write performance-critical Rust services that make full use of parallelism, async runtimes, and low-level optimisations.


 What you will do

• Build and maintain high-throughput Rust services that turn raw Solana data into real-time insights
• Design multithreaded, lock-free data structures and streaming components using Tokio and Rayon
• Implement fast, low-overhead analytics jobs to track liquidity flows and deployer behaviour using zero-copy buffers and SIMD
• Benchmark and profile workloads across CPU and GPU, and lead performance tuning sessions
• Mentor engineers on idiomatic Rust, performance patterns, and safe use of unsafe code
• Work closely with frontend and machine learning teams to expose APIs over gRPC and JSON-RPC
• Take part in a light on-call rotation to help maintain 99.99 percent uptime

 
 What we are looking for

• At least eight years of experience in systems or backend engineering
• Four or more years of hands-on experience writing production Rust
• Deep understanding of concurrency, memory layout, and performance-oriented design
• Real-world experience building real-time or high-performance systems in industries like finance, gaming, or ad tech
• Familiarity with blockchain infrastructure, especially Solana or Ethereum
• Comfortable working with event streams and data pipelines (e.g. Geyser, Kafka, WebSockets)
• Strong knowledge of computer science fundamentals including algorithms, networking, and compiler basics
• Clear communicator with solid code review and documentation habits
• Experience with databases, including time series, graph, or relational models

 
Nice to have

• Operated Solana validators or built indexing infrastructure
• Worked with data providers like StreamingFast, QuickNode, or Shyft
• Contributed to Rust open source projects or spoken at community events

 
What we offer

• Fully remote setup with flexible working hours
• $7,000 per month paid in stablecoin
• Quarterly meetups in Europe or Latin America
• Annual budget for conferences and learning
• Unlimited paid time off, with a minimum of 20 days encouraged

 Hiring process

• One hour technical deep dive focused on architecture and Rust experience
• Optional live programming session depending on how the first call goes
• Short final chat with the founder and DevRel lead
• Offer decisions usually made within three days
