We are seeking a highly skilled and self-motivated Senior Integration Developer to join our dynamic team. In this role, you will be the cornerstone of our connectivity strategy, responsible for designing, architecting, and implementing robust, scalable integrations between our platform and a wide array of third-party systems. You will work with cutting-edge technologies in a microservices-oriented environment to build seamless, enterprise-grade workflows that are critical to our business operations.

If you are a passionate problem-solver who thrives on architecting complex integrations and can work independently with zero handholding, we want to hear from you.

Key Responsibilities:

• Architect & Design: Design and architect secure, scalable, and multi-tenant integration solutions using OAuth, webhooks, and event-driven patterns.
• End-to-End Development: Lead the end-to-end development lifecycle of API integrations, from design and prototyping to implementation, testing, and deployment.
• System Integration: Build and maintain real-time and batch integrations with a variety of external systems including HR platforms, communication tools, job boards, and AI services.
• Technical Expertise: Implement and manage OAuth 2.0, SAML, JWT, Webhooks, and SSO flows securely and efficiently.
• Problem Solving: Debug and resolve complex data synchronization issues, handling challenges like API rate limiting, pagination, and throttling with elegant solutions.
• Collaboration: Work closely with cross-functional teams (Product, QA, DevOps) to deliver high-quality integration features, occasionally using React to embed them into the UI.
• Infrastructure & DevOps: Containerize applications using Docker and manage deployments in a Kubernetes environment.

Mandatory Technical Skills & Experience:

• 3+ years of professional experience in API integration development.
• Strong proficiency in Node.js (with frameworks like Express.js or MoleculerJS).
• Good working knowledge of Java and Python for building and maintaining integrations.
• Strong expertise in MySQL database design, optimization, and complex query writing.
• Hands-on experience with authentication protocols: OAuth 2.0, SAML, and JWT.
• Proven experience in building Slack and/or Microsoft Teams bots & applications.
• Solid understanding of Webhooks, message queues, schedulers, and cron jobs.
• Production experience with Docker and Kubernetes.
• Familiarity with React for embedding integration features into front-end applications.
• Experience with real-time communication technologies like WebSockets.

Required Integration Experience (Must have 5-7 from the list below):

• Communication/Collaboration: Slack / MS Teams
• Email/Productivity: Outlook / Gmail / MS Graph API
• Job Boards: LinkedIn Talent Solutions / Dice / Naukri / Indeed
• HR Systems (ATS/HRIS): BambooHR, Darwinbox, Workday, Zoho People

• Assessment Tools: HackerRank / Codility / iMocha
• AI/ML Services: OpenAI / Azure OpenAI API
• Cloud Storage: SharePoint / OneDrive / Dropbox / Google Drive

The Ideal Candidate (You will be a great fit if you):

• Have a proven track record of building real-world API integrations with 5 to 10 different external systems.
• Can independently architect complex integration solutions involving OAuth, webhooks, and SSO, particularly with ATS and HR systems.
• Possess a deep understanding of microservices architecture, message queues, and event-driven data flows.
• Are comfortable and proficient working across multiple programming languages, primarily Node.js, Java, and Python.
• Have direct experience managing the complexities of enterprise-grade APIs like MS Graph, Workday, and LinkedIn.
• Are capable of designing secure and efficient multi-tenant integration architectures.
• Have experience with AI integrations, such as leveraging OpenAI or Azure OpenAI APIs.
• Are an expert at debugging complex, multi-system data sync issues.
• Can strategically handle API limitations like job board rate limits, pagination, and throttling.

What We Offer:
