About Us

We are a fast-growing and leading company in the AI Voice space for the iGaming industry. Our AI Voice & Messaging Player Activation Platform helps casino and betting operators turn registrations into deposits and reactivate inactive players — improving Reg→Dep conversion and player LTV at a scale human call centers can't match. Our product is already used by 20+ brands across 8+ geographies. We are funded and building a team of top-tier talent.

Who We're Looking For

We're looking for a detail-oriented Operations Manager who will be the backbone of our daily operational process. You'll be responsible for data accuracy, active campaign monitoring, and vendor communication — making sure everything runs smoothly and any deviations are caught and resolved immediately.

Tasks

• Managing voice platform accounts: creating new ones, configuration, top-ups
• Communication with vendors (telephony, SMS): onboarding new ones, resolving issues with existing ones
• Working in the company's internal operations platform: data operations
• Client onboarding: creating client profiles in the platform, handing off the brief to the internal team
• Daily morning checklist control of active campaigns: comparing metrics against acceptable thresholds, checking client database uploads, confirming campaigns are running and haven't stopped, updating campaign statuses in the project management system
• Immediate escalation of deviations to the responsible manager
• Helping with monitoring and generation of Telegram accounts

Requirements

Must-have

• Accuracy with data. Transfers values between systems without errors, double-checks own work after filling in. Understands that one typo = a broken campaign.
• Execution discipline. Completes the daily checklist independently, at the same time, without reminders and without skipped items.
• Ability to compare fact against norm. Looks at a set of numbers and thresholds and spots what's out of range.
• Escalation reflex, not self-diagnosis. Sees a deviation → reports it immediately. Doesn't dig into it alone, doesn't hold onto it until end of day, isn't afraid to report bad news.
• Text communication as the primary work tool. Formulates requests briefly and clearly, runs several parallel chat threads without losing track.
• Persistence in driving an issue to resolution. With vendors: onboarding a new one, extracting an answer on an existing one. Doesn't stop at "they didn't respond."
• Learning agility. Picks up an unfamiliar interface or process from documentation and one walkthrough, then works independently.
• English B1, written.

Nice to Have

• Understanding of SIP trunking and telephony/SMS infrastructure is a plus.
• Experience communicating with vendors/providers.

What we offer

• Fully remote work format and flexible working hours.
• Competitive salary pegged to USD + performance bonuses.
• 24 days of paid vacation (sick leave, national, religious, and company holidays).
• A friendly communication culture and transparent processes.
• Dynamic work environment.
• Opportunities for professional development and career growth.
• No micromanagement — just trust, ownership, and freedom to experiment.

Our Hiring Process   

• Recruitment Interview   
• Technical Interview   
• Offer Call   

We build internal products and automation for our own teams to improve day-to-day business processes. Most tasks revolve around processing large datasets (millions of rows) and turning them into reliable, reusable outputs.

You'll work 50/50 between Python development and data work: building scripts/services and data pipelines, mainly with Pandas, plus some SQL and PySpark.

    What You'll Do

• Build internal tools and automation around data processing and reporting.
• Develop and maintain pipelines that ingest data from APIs and large files.
• Transform and validate data using Pandas; write clean, tested, maintainable Python.
• Use SQL mainly to extract data and for joins/aggregations when needed.
• Contribute to large-scale processing (PySpark/Spark) when applicable.

• Refactor and optimize existing scripts and pipelines; improve performance, readability, and reliability (tests/logging).

   

    What We're Looking For

• 2+ years of experience with Python in production.
• Strong Pandas: efficient transformations, joins/merges, memory/performance considerations.
• Solid engineering habits: tests, code review, debugging, and readable code.
• Working knowledge of SQL (MS SQL Server is our primary DB, but any RDBMS is fine).
• Comfortable with Linux and Git; daily tooling skills (e.g., VS Code).
• Excellent organizational and task management abilities.
• Self-motivated with the ability to work independently.
• Good written and spoken English communication skills.

    Nice to Have

• PySpark/Spark and/or Hadoop exposure; distributed processing concepts.
• Azure experience (storage/compute) or participation in on-prem → cloud initiatives; workflow orchestration is a plus.
• Data modeling fundamentals and basic ML understanding; а portfolio (GitHub/website) or examples of end-to-end projects/products (clean repo structure, README, tests) is a plus.

About B2Spin

We are B2Spin, and we are dedicated to delivering the best Free-to-Play Social Casino and gaming experiences by creating captivating, engaging, and unique products that are accessible to everyone. We have built a team of talented professionals from all over the globe, who are working to continually improve the experiences of our players. We are not looking to just be part of the industry, but to revolutionize it.

AI-Driven Engineering Culture

We are actively building an AI-driven engineering organization with a clear and deliberate stance: artificial intelligence is a core part of how we build and deliver software — not an experiment, not a trend, and not an optional add-on.

AI is embedded into our engineering workflows, from system design and prototyping to refactoring, testing, and code review. We expect engineers to be fully comfortable working in AI-driven environments and to treat AI as a primary productivity multiplier. Strong engineering judgment, architectural ownership, and accountability remain essential—AI amplifies our engineers, it doesn’t replace responsibility for technical decisions.

What you will be doing
• Design, evolve, and maintain core libraries, framework extensions, and shared components used across all engineering teams
• Take ownership of system performance, scalability, and high-load architecture, ensuring core services can handle massive throughput with low latency
• Proactively monitor production behavior, investigate complex application/database performance bottlenecks, and introduce advanced metrics, dashboards, and alerting systems
• Establish and advocate for best practices in concurrency, memory management, and resource utilization across the backend ecosystem
• Collaborate with cross-functional teams including backend, web, mobile, QA, and product teams
• Take ownership of specific functional areas within our large-scale architecture
• Leverage AI tools and assistants as integral parts of your development workflow—from system design to code review
• Contribute to maintaining high test coverage, predictable production behavior, and seamless scalability
• Drive engineering excellence through modern practices and continuous improvement

What we are looking for
• Deep, low-level understanding of Java internals (JVM, GC behavior, memory management, concurrency/multithreading, and performance profiling)
• Advanced knowledge of relational databases (PostgreSQL), including query optimization, indexing strategies, locking mechanisms, and connection pooling under heavy load and distributed systems architecture, specifically high-throughput event streaming with Kafka (partitioning, replication, consumer group rebalancing, and tuning).
• Strong system design, troubleshooting and debugging capabilities
• Comfortable and proactive in using AI coding assistants (GitHub Copilot, Claude Code, etc.) as productivity multipliers
• Practical experience validating, refining, and taking ownership of AI-generated output
• Upper-intermediate or higher level of English

Nice to have:
• Proven track record of building or maintaining shared libraries, SDKs, or internal tooling in a large-scale engineering organization.
• Hands-on experience with APM tools and observability stacks (Prometheus, Grafana, ELK) with the ability to define meaningful SLOs/SLIs, custom metrics, and proactive alerts.

Main technologies: Java, Spring, Spring Boot, Ebean-ORM, Quartz, Maven, Resteasy, Flyway, PostgreSQL 15, HTTP/Websockets, Netty, K8S/Docker, GCP, Jenkins, ELK, Grafana.
