Descrizione del lavoro

Backend Engineer (Specialist in High-Performance Systems) - Crypto Trading Platform - Data Indexing Solution

We’re searching for a highly skilled Data & Backend Engineer to join an innovative team tackling some of the most interesting challenges in high-throughput data systems. This isn’t just another tech role; it’s a chance to truly shape core data infrastructure and create high-performance systems capable of managing at-scale operations.

Our client, a forward-thinking company building cutting-edge products (without the buzzwords), needs someone who can roll up their sleeves and architect solutions with precision. If you're someone who thrives on solving tough technical puzzles, designing efficient systems, and working with the latest tech in data pipelines and blockchain backends, you could be the perfect fit.

What’s In It For You?

A platform to flex your skills. You’ll own complex systems end-to-end and make a real impact.

The chance to work with the latest tech in Node.js / NestJS and blockchain RPCs / gRPCs, plus exposure to high-performance, low-latency architectures.

The autonomy to make meaningful technical decisions, because you know your craft best.

A collaborative environment where solving big problems is the norm, not the exception.

Key Responsibilities for the Data & Backend Engineer

Here’s what your week might look like :

• Transforming Raw Data into Gold : Organize, clean, and index large datasets to make them usable, actionable, and scalable.
• Architecting High-Throughput Systems : Design storage solutions and data pipelines that achieve low-latency and high reliability under heavy loads. Think : systems that just work, no matter the stress.
• Owning ETL Pipelines : Plan, build, and improve Extract, Transform, Load processes that are repeatable, efficient, and rock-solid.
• Working in Node.js / NestJS : Develop and maintain backend services, APIs, or architecture, using your skills in Node.js and (ideally) NestJS to build systems that scale.
• Connecting with Blockchain Backends : Use and optimize blockchain RPCs / gRPCs where necessary, ensuring seamless interaction with data from blockchain environments.

What We’re Looking For

This role calls for a mix of technical depth, creative problem-solving, and curiosity about systems architecture. Our dream candidate will check most of the boxes below—or at least be eager to learn what’s missing :

• Solid experience in data analysis, indexing, and creating efficient data storage solutions.
• A track record of optimizing high-throughput systems—you know how to craft something scalable and performant.
• Confidence in designing ETL workflows, managing data transformation processes end-to-end.
• Hands‑on expertise in Node.js and familiarity with NestJS (or a willing interest to pick it up quickly).
• Comfort with blockchain backends (like RPCs or gRPCs). You don’t need to be a crypto wizard—but understanding this space is a definite plus.
• A love for systems thinking. The entire backend ecosystem excites you, and you see how small tweaks can lead to massive gains.

Who Will Thrive in This Role?

Someone who’s performance‑obsessed and loves wringing out every last millisecond of latency.

A pragmatic problem solver who knows when to aim for perfect and when to aim for done.

A self‑starter who likes autonomy but also plays well with others on a collaborative team.
