Qualifications

• Bachelor’s degree in computer science, software engineering, information technology or a related field.
• 4+ years of hands‑on experience with one or more modern programming languages (e.g., Python, JavaScript/TypeScript) for building backend services and APIs.
• Proven experience designing and implementing integration solutions across on‑premises and cloud environments.
• Strong understanding of integration patterns and architectural styles (e.g., point‑to‑point, hub‑and‑spoke, event‑driven, pub/sub, ESB, iPaaS).
• Hands‑on experience with API design and development, including RESTful services, SOAP, and/or GraphQL.
• Working knowledge of API security standards and protocols (OAuth2, JWT, SAML, API keys) and best practices for versioning, throttling, and error handling.
• Experience with enterprise integration platforms/tools (e.g., MuleSoft, Apigee, Kong, Workato, BizTalk, Boomi, or equivalent).
• Experience with at least one major cloud platform (Azure, AWS, or GCP).
• Solid understanding of data mapping, transformation, and orchestration techniques across heterogeneous systems.
• Experience managing the full software development lifecycle (SDLC), including CI/CD pipelines, testing strategies, and deployment across multiple environments (Dev, Test, UAT, Production).
• Strong analytical and troubleshooting skills, with the ability to diagnose and resolve complex integration and performance issues.
• Excellent communication skills, with the ability to translate business requirements into technical solutions and explain them to both technical and non‑technical stakeholders.
• Demonstrated ability to create clear technical documentation, including architecture diagrams, specifications, and data mapping references.
• Experience leading or mentoring junior developers, with a collaborative approach to working across cross‑functional teams.
• Strong project ownership mindset, with the ability to manage priorities, timelines, and stakeholder expectations independently.
• Ability to travel up to 50% of the time, based on the work you do and the clients and industries/sectors you serve.
• Limited immigration sponsorship may be available.
