About the Opportunity

A technology-driven quantitative trading firm is expanding its engineering team and is looking for a software engineer to help build the infrastructure behind its decentralized finance trading platform.

This position offers the opportunity to work across multiple layers of the trading stack, including blockchain connectivity, execution services, internal tooling, monitoring, and trading infrastructure. Engineers in this role collaborate closely with quantitative researchers and traders to develop systems that support real-time decision making across digital asset markets.

Responsibilities
  • Develop production-quality software using Rust, Python, and related technologies.
  • Build and maintain services that integrate with blockchain networks, decentralized exchanges, and smart contract protocols.
  • Design and improve execution pipelines, monitoring platforms, and operational tooling.
  • Optimize applications for performance, scalability, and reliability in production environments.
  • Support integrations with new blockchain ecosystems and emerging decentralized protocols.
  • Collaborate with researchers, traders, and engineers to deliver robust trading infrastructure.
  • Take ownership of projects from design through deployment and ongoing maintenance.
Qualifications
  • 3+ years of professional software engineering experience.
  • Strong programming fundamentals with experience building scalable production systems.
  • Solid understanding of algorithms, data structures, networking, concurrency, and distributed systems.
  • Ability to quickly learn new technologies and solve complex technical problems.
  • Experience with Rust is preferred, although candidates with strong backgrounds in C++, Go, Java, C#, Kotlin, or similar languages are encouraged to apply.
Preferred Experience

Candidates with experience in one or more of the following areas are especially encouraged to apply:

  • Digital assets, electronic trading, or financial technology.
  • Blockchain development, decentralized finance, or smart contract integrations.

  • Performance optimization and distributed application development.
  • Cloud infrastructure, observability platforms, and production monitoring tools.

Is Kotlin a good career?

Yes, Kotlin is a good career choice for developers who want to work in the Android app development, backend development, or cross-platform development space

Kotlin is a modern programming language that was designed to improve upon some of the shortcomings of Java, making it more concise, safe, and interoperable with other languages

Here are some reasons why Kotlin is a good career choice:

  1. High Demand: Kotlin is in high demand in the technology industry, especially in the Android app development space. Many companies are now using Kotlin to develop their Android apps, and the demand for Kotlin developers is growing rapidly.
  2. Compatibility: Kotlin is interoperable with Java, which means that developers can use both languages in the same project. This makes it easy for developers to migrate from Java to Kotlin and vice versa, and it also makes it easier to integrate Kotlin into existing Java-based projects.
  3. Easy to Learn: Kotlin is relatively easy to learn for developers who are already familiar with Java or other similar programming languages. Kotlin has a simpler syntax than Java, making it easier to read and write code.
  4. Concise and Safe: Kotlin is a more concise language than Java, which means that developers can write less code to achieve the same functionality. Additionally, Kotlin has built-in null safety features that help developers avoid common errors and bugs.
  5. Career Growth: Kotlin is a relatively new language, which means that there is a lot of room for growth and innovation. Developers who are proficient in Kotlin have the opportunity to contribute to the development of the language and its ecosystem, which can lead to career growth and advancement.
