Full Stack Developer (SaaS Integrations)

1-2 years of experience

Role: Build and maintain integrations between SaaS applications using REST APIs, webhooks, SDKs, and Workato. You’ll turn customer requirements into working integrations and build supporting React.js components when needed.

Responsibilities:

• Develop Python backend services and integration scripts
• Build and maintain Workato recipes and automation workflows
• Handle authentication (OAuth 2.0, JWT, API keys) and data formats (JSON, CSV, XML)
• Map and transform data between systems, and reconcile it to confirm it moved accurately
• Troubleshoot API, authentication, and mapping failures
• Add error handling, retries, logging, and monitoring
• Flag API limitations and technical risks early
• Document integrations, join code reviews, and work with Tech Leads, QA, and stakeholders

Required skills:

• Python, with FastAPI, Flask, or Django
• Strong REST API knowledge: HTTP methods, status codes, headers, pagination, rate limits, webhooks
• Postman or similar tools
• React.js and JavaScript
• Basic SQL (PostgreSQL or MySQL)
• Git

Good to have: Workato experience (not mandatory if you’re willing to learn). Experience with MuleSoft, Boomi, Zapier, Make, or n8n also counts.

Competencies: Problem-solving, independent API troubleshooting, clear communication, ownership, and a strong learning attitude.

Qualification: B.E / B.Tech / MCA / B.Sc / M.Sc in Computer Science, IT, or a related field.
