  • Practical experience with RDBMS, such as PostgreSQL.
  • Practical experience with deploying and maintaining web applications in production environments.
  • Experience with version, dependency, and build management tools (Git, Maven, Artifactory, Jenkins), deployment and monitoring tools, and code reviews.
  • Some knowledge of front-end development (HTML, CSS, JavaScript/TypeScript, React (or similar)).
  • Be a fast learner and able to take ownership of product areas.
  • Basic level (or higher) of English.
  • Bachelor's/College Degree, Computer Science/Information Technology or equivalent.

Bonus Skills (optional, but would be a plus):
  • Experience with MongoDB.
  • Experience with OAuth 2.0/OpenID Connect.
  • Knowledge of production web application security.
  • Experience with deploying to cloud environments, such as DigitalOcean or AWS and their related SDKs.
  • Experience in scalable web architecture and distributed systems.
  • Experience with financial messaging protocols (e.g. FIX).

Ideal Personality:
  • Strong planning, analytical and problem-solving skills.
  • Exceptional attention to details.
  • A positive personality and attitude - ability to derive satisfaction from their job.
  • Someone who can bring external knowledge to the team and seeks to continually improve themselves.
