Role and Responsibilities
We’re seeking an experienced Senior Ruby on Rails Engineer to join the team to help design, architect, and build out a new totally greenfield OTC product which includes a REST API for customers to place trading orders alongside a dashboard for displaying account information including balances, historical orders/trades, and deposits/withdrawals.
You’ll be responsible for helping make architectural and UI decisions on the API platform and user facing dashboard alongside the implementation of functionality for those two systems.
No prior cryptocurrency or finance knowledge is required, as we are happy to provide education and training in those areas but a strong engineering background is absolutely essential for success in this role and an interest in these fields is highly recommended.
We deeply believe in an iterative process when building technology and as a result we expect a tight feedback loop – frequent communication, asking questions when there are any uncertainties, pointing out tradeoffs to be made, and front footing anything unexpected are all strongly encouraged and highly valued.
The ideal candidate:
- Collaborates effectively with trading and engineering team members to define and refine technical requirements.
- Has good taste in engineering choices, explains and makes wise tradeoffs to balance pragmatism in achieving business requirements with adhering to technical best practices.
- Delivers clean, high quality, easily readable and maintainable code with corresponding documentation and test cases that elegantly meets the business requirements at hand.
- Prefers simplicity and likes to take a lean and iterative approach to solving problems.
- Thrives in a culture of passionate learning and teaching.
- Loves to reflect on challenges and improve process and tooling iteratively.
- Cares about solving big, systemic problems. You look beyond the surface to identify and understand root causes and seek to resolve those instead of only addressing the symptoms.
- Exhibits strong attention to detail and sweats the small things, knowing that they compound to contribute to a more holistic experience by all stakeholders.
- Understands the importance of good documentation and is proactive and consistent about recording clear and useful information as well as making it readily available to other team members and external consumers.
