Backend Engineer — Ultra-High-Performing Onchain Trading Systems

ATTN: THIS IS NOT A CHILL GIG, YOU WILL WORK A LOT - IF YOU’RE NOT READY FOR IT, DO NOT APPLYHighly 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


What You Bring


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


Who You Are


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.


You’ll work hard everyday, learn fast, and build something World-Class.

Join Velvet and help create DeFAI experience that never misses an opportunity.
