• Debug complex issues across Java/Kotlin and native C++ layers
• Analyze system logs, traces, and crashes (logcat, tombstones, systrace, etc.)
• Collaborate with reverse engineers and backend teams on system behavior

Requirements

Core Skills

• Strong experience with AOSP (building, modifying, debugging)
• Solid knowledge of:
  • Android architecture (Framework, System Services, HAL)

Who This Is For

This role is for engineers who:

We're looking for a CRM Channels & Integrations Manager who will take full ownership of our direct communication channels: SMS, WhatsApp, Telegram, Push Notifications, and IVR.

This is a highly operational and technical role sitting at the intersection of vendor management, API integrations, and CRM operations.

You'll be responsible for the entire lifecycle of communication providers: sourcing vendors, negotiating commercial terms, integrating them into Smartico, monitoring channel health, optimizing costs, and ensuring maximum delivery performance.

Our primary market is India, where communication channels require continuous attention due to changing provider quality, pricing fluctuations, OTP traffic, and strict regulatory requirements. This is not a "set it and forget it" role—you'll own these channels end-to-end.

You'll also become the technical owner of provider integrations within the CRM department. Working with REST APIs, Postman, webhooks, and API documentation will be part of your daily routine—not tasks delegated to developers.

Responsibilities

• Compare providers based on:
  • GEO coverage
  • pricing
  • throughput (messages per minute)

• Create and manage integration requests with Smartico when native development is required.
• Troubleshoot:
  • failed deliveries
  • callback issues
  • API failures

  • message delivery inconsistencies.

     

Channel Operations

Monitor channel performance daily using:

• Smartico Data Studio
• Provider dashboards
• Firebase (Push)
• Local testing devices

You'll be responsible for:

• monitoring fail rates and delivery quality;
• OTP traffic monitoring and fraud prevention;
• controlling sending limits and caps;
• monitoring provider balances;
• invoice reconciliation;
• communication channel budgeting;
• optimizing communication costs.

Incident Management

• Respond quickly to incidents such as:
  • delivery failures;
  • blocked sender IDs;
  • provider outages;
  • OTP attacks and SMS pumping.
• Escalate critical incidents to the CRM Lead.
• Prepare post-mortem reports and preventive action plans.
• Keep Product, CRM and CVM teams informed about major channel issues.

Cross-functional Collaboration

• Consult Product and CRM teams on communication channels and webhook configuration.
• Support IVR routing and communication flows.
• Prepare regular reports on channel performance, costs and improvements.

What We're Looking For

• Proven experience working with SMS aggregators, WhatsApp Business Providers (BSP), or similar communication providers at scale.
• Experience managing multiple vendors and negotiating pricing.
• Hands-on experience with:
  • REST API
  • Postman
  • Webhooks
  • API documentation.
• Ability to independently integrate providers without relying on developers.
• Understanding of communication channel economics:
  • message pricing
  • delivery quality
  • conversion
  • ROI.
• Experience monitoring large-scale communication channels.
• English sufficient for daily written communication with international vendors.

Nice to Have

• Experience in iGaming, Betting, or Online Gambling.
• Experience working with Smartico or similar CRM/CDP platforms.
• Experience with Firebase Cloud Messaging (FCM).
• Experience with Telegram bots and marketing channels.
• Experience with IVR integrations.
• Experience working with OTP traffic and understanding SMS pumping or artificial traffic attacks.
• Experience with the Indian market.

About the Product:

We are developing a security and compliance platform that helps organizations identify, prioritize, and remediate security risks across employee devices.

This solution provides real-time detection, prioritization, and automated remediation of endpoint security and compliance risks across large, distributed environments. It continuously ingests and analyzes telemetry from thousands of devices. 

About the Role:

You will join a newly formed engineering team building a next-generation, high-scale data platform from the ground up. The platform will aggregate and process large volumes of streaming data from multiple products, providing a unified view across the ecosystem. As one of the first engineers on the team, you’ll help shape the architecture, establish engineering best practices, and build scalable solutions for one of the company’s highest-volume data platforms.

Responsibilities:

• Develop scalable backend services and APIs using Java, TypeScript, gRPC, and Protobuf. 
• Develop and maintain event-driven pipelines using Kafka, stream-processing technologies (Flink or others), PostgreSQL, ClickHouse, and Redis. 
• Write, analyze, and tune complex SQL queries; improve query plans, indexing, and overall database performance.
• Develop and enhance frontend features using TypeScript and React.
• Build and maintain features related to employees, departments, devices, and role-based access control (RBAC).
• Improve the platform’s scalability, reliability, performance, observability, and cost efficiency.
• Investigate and resolve production issues, identifying and eliminating bottlenecks across services, data pipelines, and databases.
• Own features end-to-end, from technical design and implementation to production delivery.
• Collaborate in a small, highly autonomous team, contributing to architecture decisions and shaping the future of the platform.

Required Competence and Skills:

• 10+ years of experience building production-grade backend systems, with strong expertise in Java, distributed architectures, and scalable data-processing systems.
• Hands-on experience with Kafka and event-driven streaming architectures, including topic design, partitioning, consumer groups, and delivery guarantees.
• Practical experience with Apache Flink (preferred) or another stream-processing framework.
• Strong experience with PostgreSQL and ClickHouse or similar OLAP databases (e.g. TimescaleDB, Aerospike), including data modeling, query optimization, indexing, and performance tuning; familiarity with Redis and caching strategies.
• Experience with gRPC, Protobuf, and building high-volume, low-latency data processing systems.
• Experience implementing RBAC, permission models, and multi-tenant architectures.
• Experience developing frontend applications with TypeScript and React.
• Strong hands-on experience with AI coding agents (e.g. Claude Code, GitHub Copilot, Cursor), including validation of AI-generated code.
• Familiarity with CI/CD, Docker, Kubernetes, and observability in production environments.
• Proven experience as a key contributor to complex backend and data-platform projects, with the ability to work independently and deliver scalable solutions.

Nice to Have:

• Experience building Kafka-based data pipelines that integrate data from multiple backend systems.
• Experience with identity and access management solutions such as Okta, Active Directory, SCIM, or SSO.
• Hands-on experience with cloud platforms (Azure or AWS) and data-intensive infrastructure.
• Experience integrating AI/LLM capabilities into production backend systems.
