• Apply the full SDLC to deliver solutions across the product and asset portfolio, from requirements analysis through testing, deployment, and production support.
• Troubleshoot and resolve production issues across Python APIs, PostgreSQL, and React layers, conduct root cause analysis, and implement durable performance improvements.
• Collaborate with Product Owners, System Analysts, QA teams, and the backend developer to deliver platform features.
• Maintain API contracts, data models, integration guides, and runbooks for owned services.
• Participate in Agile ceremonies and CI/CD delivery practices using Azure DevOps.

You effectively communicate in various settings and provide timely, helpful information to individuals across the organization. You partner with others to get work done and create teamwork that allows the organization to achieve shared objectives. You step up to address difficult issues and are willing to champion ideas on their merits.

For This Role, You Will Need:

• 5+ years of software development experience with proven full-stack Python delivery in production environments.
• Strong proficiency in building and maintaining production-grade REST APIs using FastAPI or Django REST Framework.
• Hands‑on experience designing or consuming GraphQL APIs, including schema definition, resolvers, and client query patterns.
• Experience designing PostgreSQL schemas, writing complex queries, managing migrations, and optimizing query performance for production workloads.
• Experience designing, versioning, and consuming REST APIs, familiarity with OAuth2, JWT, and API key authentication patterns.
• Solid experience building React.js front-end interfaces with modern Java (ES6+), state management (Redux or Context API), component lifecycle management, and responsive UI design.
• Experience integrating with external SaaS or documentation delivery platforms via REST or webhook‑based workflows.
• Familiarity with Azure DevOps pipelines and sprint‑based delivery with advanced English communication skills.
