Senior Engineer

Mobileum; Bengaluru; On-site; INR 3,500,000 - 6,000,000; Full time

Job summary

Mobileum is hiring a Senior Engineer to help build agentic, GenAI-powered copilot capabilities for NTR—our carrier-grade roaming traffic steering platform. You will develop LLM-driven features while maintaining core NTR functionality on Java/distributed systems stack.

This role is a hands-on IC position focusing on technical depth, tool-calling, RAG pipelines, and observability, interacting with RAID/DB and Kafka ecosystems within a telecom context.

Qualifications

• 8–12 years of software engineering experience with Core Java backend and distributed systems.
• 1–2+ years hands-on building/shipping LLM-based/agentic apps in production.
• Telecom roaming domain exposure is a plus.

Responsibilities

• Design, build, and ship LLM-powered agentic features for NTR (natural-language configuration, intelligent diagnostics, autonomous recommendations).
• Contribute to core NTR features: roaming traffic steering, signaling, high-availability services.
• Collaborate with product/architecture, mentor engineers, and drive complex technical work independently.

Headquartered in Silicon Valley, Mobileum has global offices in Australia, Dubai, Germany, Greece, India, Portugal, Singapore and UK with global HC of over 1800+.

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 Senior Engineer to help build Mobileum's first agentic, GenAI-powered copilot capabilities for NTR — our carrier-grade, in-path roaming traffic steering platform used across 600+ operator networks. You will build LLM-powered features (natural-language configuration, intelligent diagnostics, autonomous operational recommendations) while continuing to deliver core NTR functionality on our existing Java/distributed-systems stack. This is a hands-on individual-contributor role at the intersection of applied GenAI/agentic AI and carrier-grade backend engineering — technical depth and execution, not people management.

Key Responsibilities:

Agentic Copilot Engineering

• Design, build, and ship LLM-powered agentic features for NTR: natural-language configuration assistance, intelligent diagnostics, and autonomous operational recommendations
• Implement tool/function-calling integrations so agents can safely read and act on live NTR configuration and telemetry
• Build retrieval-augmented generation (RAG) pipelines over NTR documentation, configuration schemas, and operational runbooks
• Apply context engineering, prompt design, and multi-step agent orchestration (e.g., LangGraph-style workflows) for reliable agent behavior
• Define guardrails, evaluation, and observability for agentic features (hallucination checks, action-approval workflows, audit trails)

Core NTR Engineering:

• Contribute to core NTR product features: roaming traffic steering logic, signaling/session handling, and high-availability service design
• Build and maintain backend services in Core Java, with UI components on RAID (no-code/low-code), integrated with Couchbase, ClickHouse, PostgreSQL, Redis, and Kafka
• Ensure carrier-grade reliability (five-nines availability) for both core NTR and the new copilot capabilities

Technical Execution & Collaboration:

• Take ownership of significant, complex work independently across both agentic copilot and core NTR features
• Partner closely with the Principal Engineer on architecture and technical direction for the copilot platform
• Collaborate with product, architecture, and telecom domain experts to shape and prioritize copilot use cases with the highest operator impact
• Mentor other engineers through code reviews and pairing, without formal people-management responsibility
• Represent the work in cross-functional planning and stakeholder reviews

Required Technical Skills:

Core Engineering

• Strong Core Java backend development; familiarity with RAID (Mobileum's no-code/low-code UI and ETL platform) a plus; solid system design and distributed systems fundamentals
• Experience with distributed data stores (Couchbase, ClickHouse, PostgreSQL, Redis, or similar), Kafka, and Kubernetes/OpenShift

Agentic AI & GenAI:

• Hands-on with LLM application development: prompt design, tool/function calling, RAG
• Familiarity with agent orchestration frameworks (LangGraph, LangChain, AutoGen, CrewAI, or similar) and Python
• Understanding of vector databases, context management, and agent evaluation/observability

Telecom Domain:

• Familiarity with telecom/roaming systems and protocols; NTR or similar in-path traffic-steering experience a strong plus
• Comfortable owning ambiguous, complex problems independently; strong collaborator across cross-functional teams

Required Qualifications:

• 8–12 years of software engineering experience, including significant Core Java backend and distributed systems work
• 1–2+ years hands-on building or shipping LLM-based/agentic applications (tool use, RAG, multi-step orchestration) in production
• Strong individual-contributor track record, comfortable driving complex technical work independently with minimal oversight

Preferred Qualifications:

• Telecom or roaming domain exposure, ideally including NTR or similar in-path traffic-steering products
• Experience with LangGraph, LangChain, AutoGen, CrewAI, or similar agent orchestration frameworks
• Familiarity with Model Context Protocol (MCP) or similar tool-calling/agent-communication protocols
• Vector databases and RAG pipeline experience
• Observability/evaluation practices for LLM systems
• Exposure to network/telecom operations automation

Work Experience: 8-12 Years

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