What does a JavaScript backend developer do?

A JavaScript Backend Developer is responsible for building and maintaining the server-side logic, databases, and APIs that power web applications. They use JavaScript, often with frameworks like Node.js, to process requests, manage data, and ensure smooth communication between the frontend and backend of an application. Their work ensures that web applications are scalable, secure, and efficient. JavaScript Backend Developers also collaborate with frontend developers and other team members to deliver seamless user experiences.

What are the key skills and qualifications needed to thrive as a JavaScript backend developer, and why are they important?

To thrive as a Javascript Backend Developer, you need strong proficiency in JavaScript (especially Node.js), knowledge of backend frameworks, and a solid understanding of databases such as MongoDB or PostgreSQL. Familiarity with development tools like Git, RESTful APIs, Docker, and cloud platforms, as well as relevant certifications, is highly valuable. Excellent problem-solving, teamwork, and communication skills help you collaborate effectively and deliver robust solutions. These abilities are crucial for building scalable, secure, and maintainable backend services that power modern applications.

What are the typical challenges a JavaScript backend developer faces when scaling applications for high traffic?

JavaScript Backend Developers, especially those working with Node.js, often encounter challenges related to handling high concurrency, optimizing database queries, and maintaining application performance under heavy load. Ensuring efficient memory management and implementing robust error handling are also critical when scaling. Working closely with DevOps and frontend teams to optimize APIs and monitor system health is essential for delivering reliable, scalable backend solutions.

Job description

Fullstack Developers at HRT work either on our platform team (i.e. you work on infrastructure & tooling that supports all of our research & trading capabilities) or our acceleration team (i.e. you are aligned with a specific algo research & trading team). All of our Fullstack Developers have internal customers and deeply understand end-user needs. They build backend processes to ingest and transform vast quantities of data, and UIs to visualize and action that data quickly.
Responsibilities:
  • Work on our in-house distributed-compute framework designed for execution on a large scale within HRT's compute cluster. This framework serves various teams, with our algo teams being the primary users, particularly for training complex models.
  • Work closely with our Algo Developers and traders, building backend processes and UIs for them to oversee trading processes, execute manual trades, assess risk, and research improvements to our strategies.
  • Work closely with a variety of senior technical and non-technical users and own projects end-to-end, from inception to gathering and refining requirements, forming and executing a structured plan, and managing ongoing support and iterations to the initial plan.
  • Architect web-based tooling to provide insights and enable real-time actions using financial data, operational data, trading activity, and more using React and Python.

The interview process will evaluate your backend programming skills (primarily Python), and your experience working in JavaScript/TypeScript on a modern web framework (React skills are required!). It is important that you are excited about and comfortable with working on both sides of the stack. All fullstack candidates will go through the same assessment & two technical phone interviews. We will start team alignment discussions if (when!) you get to onsite. To learn more about interviewing for technical and engineering roles at HRT, see this blog!
Profile

  • Ability to look at a technical system, understand how it works, and identify how to make it better
  • Ability to explain complicated topics to both technical and non-technical stakeholders
  • Driven by curiosity
  • Thrives within a team that consistently challenges you to improve the ecosystem around you

The estimated base salary range for this position is 175,000 to 250,000 USD per year (or local equivalent). The base pay offered may vary depending on multiple individualized factors, including location, job-related knowledge, skills, and experience. This role will also be eligible for discretionary performance-based bonuses and a competitive benefits package.
