Job description

Job Description On this role as a developer, you will contribute to the development and maintenance of APIs, support integration projects, and collaborate with cross-functional associates to deliver innovative solutions for our clients in the financial industry. Ideal candidates possess a bachelor’s degree in computer science or a related field, have a foundational understanding of modern API development, and are familiar with programming languages such as Java, Python, or JavaScript. Curiosity, strong problem-solving and communication skills, and a willingness to learn cloud-native practices on Microsoft Azure are essential. This is an excellent opportunity to grow your career in open banking while working on secure, scalable solutions in a regulated environment.
Responsibilities

• Assist in designing, coding, and testing RESTful APIs and microservices, including documenting APIs using OpenAPI/Swagger.
• Support API onboarding and lifecycle management.
• Help deploy and run services on Azure and learn containerization basics with Docker and Artifactory; exposure to AKS is a plus but not required for Jr level.
• Contribute to observability by instrumenting Dynatrace, setting up dashboards and alerts.
• Follow secure coding practices and assist with identity and access using Microsoft Entra ID (Azure AD), OAuth 2.0/OpenID Connect, Managed Identities, and role-based access control (RBAC).
• Collaborate with product managers, senior developers, QA testers, and platform engineers; participate in Agile ceremonies and contribute ideas and solutions.
• Assist in creating and maintaining clear API documentation, runbooks, and technical specifications.
• Conduct initial unit and integration testing; partner with QA to develop and execute test cases for API functionality and non-functional requirements (security, performance).
• Participate in a rotating on-call schedule for production APIs and integrations; monitor, triage, escalate, and communicate incidents to ensure fast, safe recovery for client-impacting issues.
• Help with operational tasks (triage, incident notes, post-incident reviews) and learn cost awareness practices (tagging, budgets) on Azure.
• Stay informed about trends in API, open banking, and cloud-native development, and seek opportunities to improve reliability, security, and performance.

Requirements

• Bachelor’s degree in Computer Science, Information Technology, or a related field.
• Foundational understanding of REST APIs, JSON, and OpenAPI/Swagger; familiarity with SOAP/XML is a plus.
• Familiarity with at least one programming language: Java (Spring Boot), Python (FastAPI/Flask), or JavaScript/TypeScript (Node.js/Express).
• Basic exposure to SQL and relational database concepts; familiarity with Azure SQL Database is a plus.
• Version control experience with Git (branching, pull requests, code reviews).
• Exposure to CI/CD concepts.
• Basic understanding of cloud concepts (resource groups, regions, subscriptions, RBAC, tagging) and willingness to learn Microsoft Azure services relevant to API development.
• Awareness of common identity and security practices (OAuth 2.0, OpenID Connect, JWT), secure secrets management (Azure Key Vault), and least-privilege principles.
• Interest in financial technologies, with an understanding that work must align to data privacy, security, and regulatory expectations in banking.
• Ability to approach challenges logically and develop practical solutions; strong written and verbal communication skills.
• Keen attention to detail in coding, testing, and documentation; willingness to learn from experienced colleagues and be open to feedback.

Nice-to-haves (optional)

• Exposure to containerization (Docker) and basic Kubernetes concepts (AKS).
• Familiarity with messaging/event services and asynchronous integration patterns.
• Experience with unit testing (JUnit, pytest, Jest) and API testing tools (Postman).
• Exposure to AI-assisted coding tools (e.g., Windsurf, GitHub Copilot, Azure DevOps Copilot, Tabnine) and an understanding of responsible use in regulated environments, including not sharing sensitive or client data in prompts and validating generated code for security, licensing, and quality.
• Awareness of OWASP Top 10 and secure coding practices relevant to APIs.
• Experience with API performance concepts (caching, throttling, retries) and resilience patterns.
