• Support architectural direction, solution specification, development, implementation, and delivery of new and existing APIs or services. 
• Continuously innovate in terms of process and technology, embracing emerging technologies and staying updated with new frameworks, tools, and programming languages. 
• Maintain a strong focus on code quality, coding standards, secure code (understanding of OWASP), and overall product quality. 
• Provide knowledge transfer and actively support and educate internal and external team members. 
• Support developed solutions in production under a build-it-own-it model. 

What you will need to have:

• Minimum 4 years' experience in designing, developing, and implementing software applications in an Agile environment.

• Familiarity with runtime, build, and deployment technologies as well as project tools (e.g., Eclipse, IntelliJ, GitLab, JIRA, and Confluence). Understanding of modern database technologies (relational/non-relational). 
• Knowledge of virtual infrastructure and associated services (e.g., public cloud) and containerization and orchestration technologies (ideally Docker, PCF, Kubernetes). 

What would be great to have?

• Experience working with API proxies in Apigee. 
• Knowledge of the payments industry (ISO8583, POS, etc.) is ideal. 
• Strong understanding of network topologies and common network protocols and services (DNS, HTTP(S), SSH, FTP, SMTP).
