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
  • Bachelor's degree in Computer Science, Engineering, or a related field
  • Experience working with Python and React
  • Experience working with JavaScript or TypeScript
  • Strong verbal and written communication skills
  • Excellent multitasking and time management skills
  • Ability to work independently and collaborate across teams
  • 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.
