ATTN: THIS IS NOT A CHILL GIG, YOU WILL WORK A LOT - IF YOU’RE NOT READY FOR IT, DO NOT APPLY Highly Competitive Compensation + Token Allocation Velvet (backed by YZi Labs) is building the fastest, most reliable DeFAI platform to trade any asset onchain — and we’re looking for a 10x backend engineer to take it to the next level. You’ll design and scale core trading systems in Rust, NestJS, and Go, architect event-driven backends with Kafka, and make sure our infra runs like clockwork 24/7. This is not a “maintain what’s there” job — it’s build, optimize, and own everything that matters. What You’ll Do
- Design and scale ultra-low-latency backend systems in Rust, NestJS, and Go
- Architect event-driven pipelines (Kafka or similar) that move data instantly and safely
- Optimize onchain trading infrastructure — nodes, indexers, relayers, RPC tuning, MEV-aware execution
- Own CI/CD, monitoring, and system reliability for mission-critical services
- Set up & manage monitoring tools like Datadog, Grafana, ELK, New Relic, etc
- Ship constantly. Improve relentlessly
- 3-5+ years of backend experience (TypeScript, Rust, Go)
- Proven track record with high-performance or onchain systems
- Hands-on experience with trading infra, bots, arbitrage systems and blockchain data pipelines
- Deep understanding of APIs, event streams, caching, and performance tuning
- Obsession with clean, testable, and fast code
- You’re resourceful, relentless, and precise.
- You think in microseconds, not milliseconds.
- You don’t wait for specs — you build, test, and ship until it’s perfect.
