- Collaborate closely with GenAI engineers to integrate AI-driven features and document-processing flows.
- Implement data processing pipelines for structured and unstructured data.
- Work with Google Cloud Platform services such as Cloud Run, Cloud Functions, Pub/Sub, and Cloud Storage.
- Contribute to the platform’s architecture, design patterns, and technical decision-making.
- Write automated tests and ensure a high level of code quality, maintainability, and security.
- Partner with product managers, designers, and QA engineers to deliver high-quality solutions on time.
- Document code, service interfaces, workflows, and architectural decisions.
Requirements
- 6+ years of professional software engineering experience, with significant work in both backend and full-stack roles.
- Strong proficiency in Python (FastAPI, Flask, Django, or similar).
- Solid experience with TypeScript and modern front-end frameworks (React, Next.js, or similar).
- Hands-on experience designing and implementing microservices, APIs, and backend systems.
- Strong understanding of databases: relational (PostgreSQL, MySQL) and/or NoSQL (MongoDB, Firestore).
- Experience with any cloud providers (AWS/Azure).
- Familiarity with CI/CD pipelines, Docker, Git, and modern DevOps practices.
- Strong understanding of software engineering principles: scalability, reliability, performance, and security.
- Experience working in agile, cross-functional teams on complex products.
- Excellent communication skills and ability to work with both technical and non-technical stakeholders.
Nice to Have
- Experience working with AI/ML or GenAI-driven systems.
- Experience with Google Cloud Platform
- Familiarity with Vertex AI, Gemini, or integration with LLM-powered services.
- Experience with WebSockets, event-driven architectures, or Pub/Sub.
