Trintech, Inc.

Trintech, Inc.

Software Engineering
Bengaluru, Karnataka, India
Posted on Jul 19, 2025

Summary:

We are looking for a Senior Full Stack Engineer with a strong foundation in backend development and DevOps tooling, and working knowledge of frontend technologies like React or Angular. In this role, you will build scalable APIs using Python and/or .NET, contribute to integrating AI workflows, and support deployment through modern CI/CD pipelines. You’ll also enhance frontend components as needed to connect APIs and deliver end-to-end functionality. This is a high-impact role for someone who enjoys working across the stack, with a primary focus on backend systems and infrastructure automation.

WHAT YOU'LL DO

  • Design and implement backend APIs using Python (FastAPI or similar) and .NET (C#) where applicable
  • Build and extend LLM wrappers, prompt routers, and AI orchestration logic
  • Integrate backend services with vector databases, embedding pipelines, and RAG workflows
  • Manage deployments using Azure DevOps, Docker, and Kubernetes (K8s)
  • Configure and maintain Helm charts, environments, and containerized services
  • Collaborate with frontend, AI, and QA engineers to ship production-ready features
  • Maintain logging, observability, and API-level telemetry for AI service health
  • Participate in designing proof-of-concept (POC) experiments using new AI APIs or retrieval methods

WHO YOU ARE

  • Bachelor’s degree in Engineering, Computer Science, or a related technical field
  • 5+ years of experience in backend software engineering or full stack development
  • Proficient with programming in Python and .NET (C#) for API development
  • Solid experience with RESTful API design, service integration, and microservice patterns
  • Exposure to React or Angular — enough to support frontend integration, make enhancements, and debug UI flows as needed
  • Proficient with SQL and NoSQL databases
  • Experienced with CI/CD pipelines, preferably using Azure DevOps
  • Experience deploying applications using Kubernetes (K8s), Helm, and Docker
  • Proficient with Git and basic DevOps/config management practices
  • Familiarity with vector databases (e.g., ChromaDB), embeddings, and RAG-based systems

Nice to Have

  • Exposure to LLM APIs such as OpenAI, Anthropic, or Azure OpenAI
  • Familiarity with tracing tools, error monitoring, or rate limiting for AI infrastructure
  • Contributions to POCs or prototypes in AI/ML or conversational platforms
  • Understanding of prompt lifecycle, token limits, and performance trade-offs

What You’ll Learn & Gain

  • Deep experience building scalable infrastructure for LLM-powered AI systems
  • Ownership of backend logic driving Copilot, search, and workflow-based AI interactions
  • Opportunity to scale RAG and vector-based systems from POC to production
  • A collaborative team that empowers experimentation, innovation, and technical ownership

This role presents an exciting opportunity to design and deliver the backend foundation for AI-enhanced enterprise platforms. If you're driven to combine engineering precision with AI innovation, we encourage you to apply.
