Senior Backend Engineer

The Mission

We aren’t looking for a traditional server administrator or a standard database developer who just writes basic CRUD APIs. We need an elite Backend Systems Architect who can build world-class, hyper-scalable, and fault-tolerant infrastructure with surgical precision. Your job is to engineer our core distributed systems, optimize real-time data pipelines, and ensure absolute service reliability under immense global load. This is a remote, high-availability role for a technical powerhouse who views backend systems as a high-performance engine and is comfortable operating at the absolute frontier of the Web3 economy.

We value structural integrity, clean concurrent code, and engineering momentum over corporate credentials. Whether you have designed high-throughput financial rails or led the architecture for high-velocity distributed platforms, we care about your ability to ship. If you have the analytical rigor to handle massive data concurrency, eliminate latency spikes, and protect data integrity, we will give you the runway to build our engine room.

Key Responsibilities

Backend Systems Development: Design, scale, and maintain high-performance server-side logic that remains rock-solid under heavy concurrent user velocity.

API Architecture: Build and optimize flexible, self-documenting API schemas that connect our complex internal data layers seamlessly to our consumer interfaces.

Distributed Systems: Architect resilient, decentralized system nodes that communicate asynchronously with zero single points of failure.

Database Design: Structure highly performant database schemas, indexes, and caching strategies to ensure sub-millisecond retrieval speeds for critical data.

Infrastructure Scalability: Constantly stress-test, optimize, and scale our core service clusters to handle explosive traffic spikes and massive computational throughput.

Service Reliability: Implement rigorous monitoring, automated failover protocols, and strict error-handling mechanics to ensure absolute 24/7/365 system uptime.

The Technical Stack

You must possess elite-level, hands-on mastery of the following stack:

Node.js: Ability to stand up independent microservices, experience with REST APIs, understanding of advanced event loop and memory optimizations.

GraphQL: Complex schema design, familiarity with resolver optimizations such as N+1 problem and dataloaders, efficient context management with high concurrency requests.

Golang: Concurrent programming patterns (goroutines/channels), and high throughput microservice experience.

MongoDB: Advanced indexing strategies, aggregation pipeline optimizations, non-relational database design.

Kafka: Real-time event streaming, message broker architecture, and distributed partition management.

Redis: In-memory caching architecture, handling of real-time pub/sub mechanics, knowledge of efficient commands and operations.

The Requirements

The "Systems Architect": Proven experience shipping production-grade, highly resilient backend ecosystems. You have a deep understanding of data structures, concurrency, and network protocols.

Analytical Rigor: You don't guess when it comes to systems performance. You use profiling tools, load-testing frameworks, and internal monitoring metrics to track down and eliminate bottlenecks.

Hyper-Availability: This isn't a 9-to-5. Our ecosystem runs 24/7/365. You must be available 7 days a week to handle real-time hotfixes, critical system deployments, and sudden market surges.

Web3/Internet Culture Intuition: You understand the unique technical challenges of digital asset data, transaction validation speeds, and fast-paced, digital-native environments.

Operational Excellence: Self-motivated and highly organized; you write clean, idiomatic code, write bulletproof tests, and manage your development pipeline without hand-holding.
