Senior AI Engineer – Agentic AI & Backend

ACROSSTEK™
Karnataka, India

Experience: 5+ Years

Location: Bangalore

Work Mode: Hybrid

Employment Type: Full-time

About the Role

We are looking for a Senior AI Engineer to design, develop, and operate production-ready AI systems powered by LLMs and intelligent agents.

You will be responsible for building the engineering foundation behind AI agents, MCP-based integrations, agentic workflows, and AI-powered connectors. The role involves taking solutions from architecture and development through deployment, monitoring, evaluation, and continuous improvement.

This is a hands-on engineering position, not a research or prompt-engineering role. You should enjoy solving complex engineering problems and building reliable AI applications that can operate at scale.

Key Responsibilities

  • Design and develop MCP servers that allow AI agents to securely access data, APIs, and business capabilities.
  • Build robust agentic workflows involving tool calling, orchestration, multi-step execution, and human approval when required.
  • Develop integrations that connect AI agents with external applications, platforms, and enterprise systems.
  • Own services throughout their lifecycle, including architecture, development, deployment, monitoring, and production support.
  • Establish evaluation processes to measure agent accuracy, reliability, and behavioral consistency.
  • Implement logging, tracing, and observability to understand and troubleshoot AI-agent behavior.
  • Improve systems for performance, latency, cost efficiency, scalability, and reliability.
  • Create reusable SDKs, frameworks, and engineering components for AI development.
  • Work closely with Product, Design, Engineering, and customer-facing teams to convert requirements into production solutions.
  • Evaluate emerging technologies across the rapidly evolving LLM and agent ecosystem.

Required Qualifications

  • 5+ years of software engineering experience with experience delivering production systems.
  • Strong hands-on expertise in Python backend development.
  • Proven experience developing and deploying LLM-powered applications or AI agents.
  • Practical knowledge of:
  • Function/tool calling
  • Structured outputs
  • Prompt chaining
  • Agent orchestration
  • Multi-agent systems
  • Human-in-the-loop workflows
  • Experience developing MCP servers or equivalent AI integrations/tool interfaces.
  • Understanding of LLM evaluation and testing methodologies.
  • Experience deploying applications using AWS, GCP, or similar cloud platforms.
  • Good knowledge of Docker and containerized applications.
  • Experience with asynchronous programming in Python.
  • Strong understanding of APIs, backend architecture, and distributed services.
  • Ability to make sound technical decisions while keeping the end-user and business requirements in mind.

Preferred Skills

  • Experience with LangGraph, LangChain, Anthropic SDK, Pydantic-AI, CrewAI, or similar agent frameworks.
  • Familiarity with AI observability and tracing platforms such as Langfuse, LangSmith, or OpenTelemetry.
  • Exposure to LLMOps, agent evaluation, and AI monitoring.
  • Experience with digital analytics, application monitoring, APM, or observability platforms.
  • Contributions to open-source AI/engineering projects, technical blogs, presentations, or community initiatives are a plus.
