You will be responsible for designing and delivering high-quality code for Esprow's web products. Our tech stack includes Java, Spring, React, TypeScript, PostgreSQL, MongoDB, Redis, and many other interesting technologies. This position does not require you to be full-stack, however, as a senior or lead back-end developer, we expect some level of understanding of related technologies, including DevOps/infrastructure and front-end (JavaScript/TypeScript). You must be able to take ownership of the work, including some testing and support phases, and follow through every step required until delivery is achieved. The job requires good communication skills, the ability to work independently, in a small team environment, to deliver on-time and on-quality work.

  • Collaborate with the Development Manager and the Development Team to ensure successful project deliveries.
  • Suggest product and process improvements.
  • Document own area of responsibility and code. Share knowledge with the rest of the team.
  • Assist in maintenance and improvement of the development infrastructure.
  • Assist with technical interviews of new candidates.
  • Assist Support Team in resolving technical issues of clients.
Skills and Qualifications:
  • Strong core Java experience.
  • Solid understanding of OO concepts, knowledge of design and architectural patterns, and ability to write clean code.
  • Extensive experience with the Spring Framework (Boot, MVC, Security, Data JPA with Hibernate, AOP).
  • Familiarity with RESTful and WebSocket APIs.
  • 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.
  • Someone who can create a positive environment and strong team bonds.
  • Able to work independently, proactively and under pressure against multiple deadlines.
Benefits You Will Enjoy:
  • Full time permanent position (onsite or remote).
  • Five days' working week [9am to 6pm – with flexitime].
  • Competitive remuneration package.
  • Complimentary coffee/tea and snacks (for onsite position).
  • Professional, efficient, and friendly team.
  • Training and professional growth.
  • Career path in a fast-growing technology company within global markets.
