Senior Backend Software Engineer (Java)

We’re looking for an experienced software engineer to be a key contributor in developing cloud-based services that will drive the future of the business. You will join our small and dynamic Cloud Services team, using the latest technology and tools to build high-quality, cross-platform solutions that delight our customers.

Responsibilities:

  • This is a technical hands-on role, with responsibilities ranging from being at the vanguard of solving technical problems to venturing into unchartered areas of technologies to solve complex problems.
  • Directly responsible for consistently delivering high-quality, scalable, production-ready backend/server code in Java by implementing best practices in software engineering, including coding standards, testing and deployment procedures.
  • Partner closely with a cross-functional team of key stakeholders (Engineers, Architects, Product Managers, QA, Operations, and Business Partners) to design and implement end-to-end solutions that meet user needs as well as engineering/operational/business goals.
  • Mentor junior developers using expertise in software development methodology and frameworks, in areas such as quality, security, and scalability.


Qualifications:

  • 8+ years of software engineering experience, including a successful track record developing customer-facing SaaS/PaaS products.
  • 5+ years working experience in core Java and Spring Framework.
  • 3+ years working experience within microservice architecture, specifically utilizing REST services and JSON.
  • Experience in developing applications that are deployed in AWS.
  • Excellent understanding of O/R mapping concepts and tools (Hibernate, JPA).
  • Fluent in Databases/SQL (MySQL experience preferred).
  • Excellent programming discipline: data structures, complexity analysis, object-oriented principles, design patterns, and unit testing.
  • Excellent knowledge of the development challenges inherent with highly scalable and available web/mobile applications.
  • Experience with API development and integration with 3rd-party services is preferred.
  • Experience mentoring junior engineers.
  • BS/MS in Computer Science/Engineering or equivalent.
