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

  • GEO coverage
  • pricing
  • throughput (messages per minute)

• Integrate providers into Smartico.

• Create and manage integration requests with Smartico when native development is required.

  • 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 with the Indian market.

From individual contributors to entire engineering functions, we support companies at different stages of growth and hiring maturity.

We value building strong relationships with our clients and becoming a trusted partner, understanding our clients’ businesses and needs rather than being just another cold vendor.

• Inbound marketing background using the LinkedIn Ads platform, Google Ads, etc.
• Tools integration via direct connectors, APIs, and automation engines.
• Using and building AI agents for process management, handling tasks, and writing messages.

Your skills:

• Good command of English.
• Great understanding of business processes and the value revenue operations bring to the business and its customers.
• Great copywriting skills, both with and without AI assistance.
• Strong self-management skills and a high level of ownership.

• Curiosity about AI, automation, and new technologies, with a willingness to experiment and learn.

• Manage daily outbound and revenue operations workflows.
• Automate repetitive processes and maintain existing automations.
• Build reporting that clearly shows pipeline activity and results.
• Keep CRM and data systems accurate and up to date.
• Nurture target accounts through relevant and timely communication.
• Build a scalable and measurable ABM process.

• Increase the volume of qualified conversations with target customers.

   

Your basic working cycle:

• Define routine areas that can be automated and identify automation tasks.
• Oversee automation development and test solutions after delivery.
• Maintain automations.
• Employ automation as part of the daily routine and move on to the next stage.

We don’t expect you to have all the answers on day one.

We do expect you to be excited about figuring them out.

⸻

Tools

Our current operational hub is Notion.

We’re actively building and expanding our stack and expect this role to help shape it.

Experience with tools such as Apollo, Clay, LinkedIn Sales Navigator, Instantly, Smartlead, Make, Zapier, OpenAI, ChatGPT, Perplexity, or similar platforms is a strong plus.

⸻

What are the working conditions

• Remote-first setup with flexible working hours and unlimited paid time off
• Collaborative team, flat structure, and minimal bureaucracy
• Full coverage of taxes, work-related expenses, and everything needed to do your job well
• Competitive compensation with a strong performance-based bonus
• Health insurance, gym membership, and other benefits

We are an iGaming media buying team focused on Facebook traffic acquisition across Tier 1–2 GEOs under the CPA model through external affiliate programs.

We provide the full infrastructure needed for traffic acquisition, including accounts, farming, creatives, offers, analytics, and technical support.

We are looking for a hands-on Team Lead who can combine strong media buying expertise with team leadership. You’ll be responsible for managing a team of buyers, monitoring performance, supporting launches, analyzing traffic, and making sure the team consistently delivers strong results — while continuing to run traffic yourself.

HOW YOU WILL MAKE AN IMPACT:

• Manage and develop a team of approximately 5–6 Media Buyers;
• Monitor the team’s traffic performance and identify opportunities for optimization and growth;
• Monitor the full funnel from click to registration and deposit;
• Analyze key performance metrics such as CPM, CTR, CPC, CR, CPA, ROI, approval rate, and other relevant indicators;
• Identify campaign bottlenecks and decide whether to optimize, scale, or stop campaigns;
• Take into account holds, caps, qualification requirements, and actual revenue when evaluating campaign performance;
• Compare buyer performance and share successful approaches and working strategies across the team;
• Support buyers with campaign launches, optimization, and troubleshooting;
• Generate and validate hypotheses around creatives, funnels, offers, and GEOs;
• Monitor the quality and results of campaign testing;
• Scale validated approaches across the team;
• Personally launch and validate campaigns and priority hypotheses;
• Monitor the market and stay up to date with changes in iGaming and Facebook media buying;
• Use AI tools for analytics, performance analysis, hypothesis generation, and daily workflow optimization;
• Identify opportunities to improve and automate the team’s buying processes;
• Analyze performance drops and identify their causes based on data;
• Help onboard and mentor new buyers and support their professional development.

WHAT WILL HELP YOU SUCCEED IN THE ROLE:

• 2+ years of hands-on experience with Facebook Ads in Gambling/iGaming;
• 1+ year of experience managing a team of Media Buyers;
• Strong practical experience working with the CPA model;
• Recent and relevant experience in iGaming — you should be actively familiar with the current gambling media buying market;
• Proven experience working with Tier 1–2 GEOs;
• Strong understanding of the full traffic funnel and key performance metrics;
• Experience independently launching and optimizing Facebook campaigns;
• Experience managing and scaling significant traffic volumes;
• Experience managing a team of approximately 5–6 buyers;
• Previous team experience with approximately $200K+ in monthly spend is highly relevant;
• Experience generating approximately $30–40K+ in personal monthly spend is a strong advantage;
• Experience with Binom, Keitaro, or similar tracking platforms;
• Understanding of BMs, advertising accounts, and the general Facebook buying infrastructure;
• Strong analytical mindset and ability to make decisions based on data;
• Ability to identify problems quickly and take ownership of the result;
• Practical experience using AI tools in media buying, analytics, or workflow optimization;
• Willingness to remain hands-on and continue running traffic personally, rather than moving entirely into people management.

WHY YOU'LL LOVE IT HERE:

• Flexible working hours and a remote work setup, so you can plan work around your life and not your life around work!
• Unlimited vacation days and paid sick leave—because your rest matters.
