Jobs at Djinni

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: Advanced asynchronous architecture, event loop optimization, and high-performance package deployment.
• GraphQL: Complex schema design, advanced resolver optimization, and efficient query/mutation orchestration.
• Golang: Concurrent programming patterns (Goroutines/Channels), high-performance memory management, and microservice optimization.
• MongoDB: Non-relational database design, aggregation pipeline optimization, and advanced indexing strategies under heavy write-loads.
• Kafka: Real-time event streaming, message broker architecture, and distributed partition management.
• Redis: In-memory caching architecture, real-time pub/sub mechanics, and high-velocity data state retention.
• Microservices Architecture: Containerized, horizontally scalable service decoupling, internal RPC communication, and distributed event-driven logic.

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.

Operational Details

• Location: Fully Remote.
• Schedule: On-call 7 days a week (Requires high flexibility to handle real-time hotfixes, system maintenance, and global release cycles).
• Payment: All compensation is processed in digital assets (USDC/USDT).

Why Join Us?

We offer more than just a typical software engineering ticket-shuffling job; we offer the chance to architect the engine of a global powerhouse.

• Extreme Technical Autonomy: We value clean execution over red tape. You will have the freedom to design, optimize, and break new ground within a high-speed environment.
• Global Infrastructure: Your code will run the core systems touched, tested, and relied upon by thousands of users every single second across a worldwide landscape.
• A Culture of Momentum: Join a team that moves at the speed of light. If your system architecture is tested and ready to ship on a Sunday night, we push it to production.
• High-Growth Upside: We value "potential over pedigree." For a senior engineer who takes extreme ownership of our core platform, there is a clear, unrestricted runway to lead the entire engineering organization.

Our client is a fast-growing, innovation-driven company working at the forefront of robotics and AI. Their mission is to build advanced autonomous robotic systems capable of operating in real-world environments. They combine expertise in machine learning, computer vision, and robotics to solve complex problems in perception, manipulation, and task planning.

Their teams are composed of highly skilled engineers and researchers who thrive on tackling cutting-edge challenges, engaging in deep technical discussions, and building systems that move from research to real-world production. They value independence, technical excellence, and the ability to deliver in fast-paced, experimental environments.

About the Role:

We are seeking a Principal Robotics AI Engineer for our client. In this role, you will lead the technical development of AI-based robotic systems with a strong focus on dexterous manipulation, perception, and task planning.

You will play a key role in designing and improving data pipelines, working with egocentric datasets, and applying modern AI approaches such as VLA, RL, and VLMs to real-world robotics problems. This is a highly impactful role where you will help shape both the AI systems and the underlying data infrastructure that powers them.

Responsibilities:

• Lead the development of AI-driven autonomous robotic systems with a focus on dexterous manipulation and task planning;
• Build and maintain egocentric data pipelines, including data collection, annotation, and quality assurance at scale;
• Apply VLA, reinforcement learning, and VLM-based approaches to manipulation tasks in industrial, retail, and household environments;
• Collaborate with robotics labs to understand data and pipeline requirements and deliver high-quality training datasets;
• Contribute to perception and machine learning systems deployed on physical robots operating in complex real-world environments;
• Help define and guide the technical direction of AI tooling and data infrastructure;
• Drive technical decisions and work independently to deliver production-ready solutions.

Requirements:

• 5+ years of hands-on experience in robotics AI, ideally at companies or labs such as Boston Dynamics, Figure, Tesla Optimus, Apptronik, or similar;
• Strong expertise in perception and ML systems for autonomous robots, including computer vision, 2D/3D scene understanding, object detection, and manipulation;
• Experience with VLA models, reinforcement learning, and VLM-based task planning in real-world deployments;
• Deep understanding of egocentric video data and how manipulation datasets are structured for robot learning;
• Proven ability to lead technical work independently and deliver in production environments;
• Strong problem-solving skills and ability to work in fast-paced, cutting-edge environments;
• PhD or equivalent industry experience in ML, robotics, computer vision, or a related field.
