About the Role

We're looking for a senior Data Architect to design and modernize an Azure data platform, including the data architecture underpinning GenAI/RAG/Agentic applications. This is an architecture role, not hands-on RAG/ML development — the focus is on how enterprise data and knowledge are ingested, prepared, stored, governed, and made available for retrieval and AI consumption.

Must-Haves

• Azure Cosmos DB — hands-on experience with data modeling, partitioning, indexing, RU/throughput and cost optimization, consistency, Change Feed
• Proven experience designing data platforms supporting GenAI/RAG use cases
• AI-ready data architecture experience
• A real project where the candidate designed or contributed to the data architecture supporting a RAG, GenAI, or Agentic AI application
• Azure Synapse Analytics — depth across workload patterns (Pipelines, Spark, Serverless SQL, Dedicated SQL Pools)
• Azure Databricks
• Azure SQL MI / SQL Server / T-SQL
• Azure Data Lake / Lakehouse architecture
• Azure Functions
• Experience with structured and genuinely unstructured data (documents, PDFs, scans, images, email, free text)
• Metadata/configuration-driven ingestion — reusable, scalable design for onboarding new data sources
• Demonstrated architecture ownership — real decisions made, not just pipeline implementation
• At least 4 years of recent (not dated) hands-on Azure experience
• Must be an Architect by role, not a Data Engineer

What You'll Do

• Take over an existing, problematic data platform, quickly assess it, and deliver both tactical fixes and a longer-term target architecture
• Design a reusable ingestion architecture for heterogeneous sources (databases, APIs, files)
• Make technology-neutral calls on when Databricks/Synapse/ADF are actually needed — and when they're not
• Produce detailed, implementation-ready architecture documentation for engineering teams
• Own data governance, data quality, and incremental processing
• Communicate effectively with both technical and business stakeholders

A Note on GenAI/RAG

You won't be building RAG solutions or AI agents yourself. What's required is experience designing the data architecture around such applications — how enterprise data and knowledge get ingested, processed, indexed, and made available for retrieval and AI consumption (document processing, OCR, chunking, embeddings, vector search, etc.), including where Cosmos DB fits into that picture.

Interview Process

1. Intro call
2. Technical interview (~1 hour)

Be ready to walk through 2–3 concrete project examples using: problem → options considered → your decision → rationale → implementation → result. The focus is less on definitions and more on how you think as an architect and how quickly you can turn a messy existing situation into practical direction for an engineering team.

The role is based in the Kyiv region, and we will expect you to work full-time in the office. We have a shuttle service from the nearest metro station.

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

Vendor Management

• Source and evaluate new communication providers for SMS, WhatsApp, Telegram, Push, and IVR.
• Compare providers based on:
  • GEO coverage
  • pricing
  • throughput (messages per minute)
  • API quality
  • reliability
  • vendor reputation.
• Negotiate commercial terms and improve pricing.
• Maintain an internal registry of tested providers and routes.
• Support vendor agreements together with the Legal team.

Technical Integrations

• Own the full provider integration process.
• Test provider APIs using Postman.
• Configure and validate webhooks.
• Integrate providers into Smartico.
• Conduct end-to-end testing before production launch.
• Launch marketing A/B tests to validate new communication channels.
• 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.

What We Offer

💻 Fully remote work from anywhere in the world.

⚡ Fast decision-making with minimal bureaucracy.

🤝 A collaborative team of professionals passionate about building great products.

📈 Support from experienced leaders who genuinely invest in your professional growth.

🏖 20 paid vacation days, 5 additional paid days off, and paid sick leave.
