Senior Rust Engineer

Location: Remote (CET +/- 4 hours) Type: Full-time

Compensation: $72K - $90K

We are a stealth-stage DeFi Trading & Intelligence platform dedicated to the Solana ecosystem. We are building the critical infrastructure required for sophisticated on-chain decision-making—ranging from real-time signals and smart money tracking to enterprise-grade fraud detection. Our platform delivers high-fidelity on-chain analytics through a high-performance API. We are a small, fast-moving team tackling the most challenging problems in blockchain data. As a Senior Rust Engineer, you will play a pivotal role in architecting systems that process millions of Solana transactions in real-time.

This is an early-stage startup environment. We are looking for an engineer who thrives on high ownership, fast iteration cycles, and the opportunity to ship code that immediately impacts production environments. If you are passionate about building high-throughput infrastructure and solving "hard" data problems, we want to hear from you.

• System Architecture: Design and build high-throughput Solana transaction indexing systems.
• Data Pipelines: Develop real-time analytics pipelines and continuous aggregation engines.
• Intelligence Engines: Implement smart money detection, wallet tracking, and fraud detection algorithms.
• API Infrastructure: Maintain and scale our enterprise-grade gRPC and WebSocket API infrastructure.
• Performance Optimization: Ensure low-latency data processing by utilizing advanced async patterns and lock-free structures.

• Rust Expertise: 4+ years of professional experience writing production-grade Rust.
• Solana Ecosystem: Expert-level understanding of Solana transactions, programs, RPC, and Geyser.
• Concurrency: Deep expertise in parallelism and concurrency (Tokio, Rayon, and async patterns).
• Database Management: Proficiency with PostgreSQL, TimescaleDB, and ClickHouse.
• Messaging & Communication: Experience with RabbitMQ (or similar message queues), gRPC, and WebSockets.
• Architecture: Proven experience building and maintaining microservice architectures.

Bonus Points:

• Prior experience in trading systems or financial data.
• Experience with EVM-based chains (Ethereum).
• Familiarity with Carbon or other Solana-specific decoders.
• Hands-on experience with Kubernetes.
• A track record of building real-time streaming pipelines.

• Competitive Compensation: Paid in USDT.
• High Autonomy: Direct influence on the product roadmap and architectural decisions from day one.
• Remote-First: Work from anywhere within the CET +/- 4 hours time zone.
• Cutting-Edge Tech: Solve unique problems in the fastest-growing blockchain ecosystem.
• Talent-Dense Team: Work alongside experienced founders and engineers in a flat organizational structure.
