About NTR:

NTR (Network Traffic Redirector) is Mobileum's flagship in-path roaming traffic steering solution, deployed across 600+ operator networks worldwide and engineered for five-nines availability. Built on Core Java, RAID (our no-code/low-code UI and ETL platform), Couchbase, ClickHouse, PostgreSQL, Redis, Kafka, and Kubernetes/OpenShift, NTR steers roaming traffic in real time at carrier scale. We're now building agentic, GenAI-powered copilot capabilities on top of NTR, enabling autonomous configuration, natural-language operator assistance, and intelligent, self-healing traffic-steering decisions.

Overview:

We are hiring a Principal Engineer to architect Mobileum's agentic, GenAI-powered copilot capabilities for NTR — our carrier-grade, in-path roaming traffic steering platform used across 600+ operator networks. You will design how multi-agent orchestration, tool integration, and retrieval-augmented generation (RAG) let NTR autonomously configure and operate itself, while staying hands-on with core NTR engineering and mentoring the wider team. This is a deep technical architecture role: you set the target-state design and technical standards for agentic AI on NTR, and you're still writing code and prototyping alongside the team.

Key Responsibilities:

Agentic Architecture & Strategy

• Define the target-state architecture for NTR's agentic copilot platform: multi-agent orchestration, tool/function-calling integration, and RAG pipelines over NTR configuration, telemetry, and documentation
• Select and evaluate agent frameworks, LLM providers, and orchestration patterns (e.g., LangGraph-style stateful workflows)
• Define the model-hosting strategy (self-hosted/on-prem vs. API-based LLMs), accounting for the data-residency and security constraints typical of Tier-1 telco on-premise deployments
• Establish safety, guardrail, and evaluation standards for autonomous or semi-autonomous NTR actions (approval workflows, audit trails, hallucination/regression checks)

Platform & Integration Engineering

• Architect the integration layer between agentic services and NTR's Core Java backend (with a RAID-based no-code/low-code UI), ensuring safe, auditable access to live configuration and telemetry
• Design context management, memory, and retrieval strategy across NTR's data stores (Couchbase, ClickHouse, PostgreSQL)
• Set standards for agent observability, tracing, and production monitoring

Core NTR Engineering

• Remain hands-on with core NTR features and architecture: roaming traffic steering, signaling/session handling, and high-availability service design
• Ensure the copilot platform meets NTR's carrier-grade, five-nines reliability bar

Technical Leadership & Enablement

• Provide architectural guidance and mentorship to the Technical Lead and engineers building on the platform
• Partner with product, telecom domain experts, and customers to prioritize agentic use cases with the highest operator impact
• Represent the agentic AI roadmap in architecture reviews and executive updates

Required Technical Skills

Core Engineering

• Deep expertise in Core Java, distributed systems, and backend architecture at carrier scale; familiarity with RAID (Mobileum's no-code/low-code UI and ETL platform) a plus
• Strong system design across distributed data stores (Couchbase, ClickHouse, PostgreSQL, Redis, or similar), Kafka, and Kubernetes/OpenShift

Agentic AI & GenAI

• Proven experience architecting production LLM/agentic systems: multi-agent orchestration, tool/function calling, RAG
• Deep familiarity with agent frameworks (LangGraph, LangChain, AutoGen, CrewAI, or similar) and Python
• Strong grasp of vector databases, context/memory management, and agent evaluation, safety, and observability practices

Telecom Domain

• Familiarity with telecom/roaming systems, protocols, and roaming analytics; NTR or similar in-path traffic-steering experience a strong plus

Leadership

• Strong technical influence and mentorship without relying on direct management authority

Required Qualifications

• 12–16 years of software engineering experience with deep distributed systems/backend architecture expertise (Core Java)
• 3+ years hands-on designing and shipping production LLM-based or agentic AI systems
• Proven ability to set technical direction and influence across teams without direct authority

Preferred Qualifications

• Telecom/roaming domain experience, ideally including NTR or in-path traffic-steering products
• Deep experience with agent orchestration frameworks and multi-agent architecture patterns
• Familiarity with MCP/A2A or similar agent communication protocols
• Experience with model evaluation, safety/guardrails, and production LLM observability
• Exposure to fine-tuning (LoRA/QLoRA) or model serving infrastructure

Work Experience: 12-16 Years

Educational Qualification: BE. / B.Tech., M.E./M.Tech. or M. Sc. in Computer Science / Electronics Engineering / MCA

Location: Bangalore
