• Collaborate with cross-functional teams to align the AI platform with business goals and internal use cases
• Troubleshoot and resolve issues across integrated systems to ensure reliable, end-to-end agentic workflows.

Requirements:

• 5+ years of experience in Software Development
• Real, hands-on experience building agentic AI systems - genuine understanding of how they work, beyond just using existing tools or frameworks off the shelf.
• Strong, in-depth AWS experience - real platform engineering depth, not incidental or side use of AWS.
• Strong Python knowledge
• Deep experience building knowledge graphs, ideally with AWS Neptune or Neo4j - especially valuable for this role.
• Experience with LLMs, prompt engineering, and AI integration patterns.

The Role

We're looking for a strategic, data-driven Head of VIP to own the design, performance, and continuous optimization of our VIP retention program across T1 and T2 casino markets. You'll set the strategy, bring innovation, novel ideas, own the numbers, and lead through a dedicated VIP Team Leader who runs day-to-day execution. You'll spend your time on segmentation, cohort analysis, program design, and cross-functional influence, stepping into the player-facing world only for your top 10–20 Tier-1 accounts and genuine crisis escalations.

What You'll Own

• Strategic Analytics: Design and maintain our multi-tier segmentation (Mass Market / Pre-VIP / VIP) and cohort framework (Active, Churn, Reactivated, New), and deliver 7-day, 14-day, and monthly performance intelligence across every project and market.
• Program Strategy and Tactics: Own the annual VIP Retention Marketing Calendar — campaign design, offer mechanics, seasonal activations, and a structured testing roadmap.
• Retention & Reactivation: Build predictive churn early-warning capability, design win-back mechanics, and personally step in on high-stakes closure situations escalated by your Team Leader.
• Business Performance: Own retention rate, churn reactivation, NGR/deposit growth, LTV, bonus efficiency ratio, and surplus margin — and report on them monthly to leadership.
• Cross-Functional Leadership: Partner with Product, Marketing, CRM, Compliance, and Finance to keep VIP strategy aligned with the wider business, and represent the segment at board level.
• Team Leadership: Set the department's KPI framework and give strategic direction to your VIP Team Leader — who owns scheduling, coaching, QA, and the day-to-day player relationship.

What We're Looking For

• Proven track record building or scaling a VIP program in iGaming/gambling, ideally across regulated T1/T2 markets.
• Fluency with the metrics that actually run a VIP book: NGR (not just GGR), cohort-based LTV, LTV:CAC, bonus efficiency, and surplus margin.
• Experience leading through a manager layer rather than running a desk personally — comfortable setting direction and holding a Team Leader accountable to KPIs, not doing the coaching yourself.
• Strong cross-functional influence — you've shaped Product, Marketing, and Compliance decisions with data, not just requested changes.
• Working knowledge of the regulatory constraints that shape VIP marketing in T1/T2 markets (e.g. UK affordability checks, MGA/EU advertising rules, responsible gambling obligations).

🎓 Education & Experience:

• Bachelor’s degree in Business, Marketing, or a related field.
• A minimum of 3 years of experience in VIP management or a similar role, with at least 2 years in a leadership position.

We are looking for a Senior Software Engineer for the connectivity stack of a large-scale data platform. The work spans three areas:

• Client connectivity — drivers and client libraries used by applications and BI tools
• Source connectivity — connectors to databases and data systems, including authentication, metadata discovery, and query/data pushdown, with certification and upgrade support
• Agent & service connectivity — tool interfaces and integrations for AI-agent access to the platform

Deep expertise in one of these areas is enough — you'll grow into the adjacent ones over time. This is a role for an engineer who cares about API and protocol stability, backward compatibility, and interoperability with the tools enterprises actually use. You will lead the design and delivery of substantial components, working within an established architecture alongside US-based engineering reviewers.

This is a systems-level, backend engineering role focused on drivers, protocols, and distributed services — not application development or CRUD services.

Responsibilities

• Lead the design and delivery of connectivity components — client drivers, source connectors, and service integrations — turning ambiguous initiatives into well-scoped, reviewable milestones
• Produce technical designs, explain architectural trade-offs, and surface compatibility, security, and delivery risks early
• Maintain backward compatibility and API/protocol stability; build compatibility, interoperability, and performance test suites
• Develop and maintain connectors for major BI tools, collaborating with the technology partners behind them
• Diagnose complex client/server, protocol, and distributed-system failures; drive root-cause analysis of customer-reported and escaped defects
• Improve diagnostics, logging, observability, and supportability of the connectivity stack
• Contribute upstream to open-source projects (e.g., Apache Arrow) where agreed
• Mentor engineers, participate in code and design reviews, and communicate progress and risks clearly across a distributed team

Required Qualifications

• B.S. or M.S. in Computer Science, Computer Engineering, or a related field — or equivalent practical experience
• 8+ years of production software engineering experience
• Deep proficiency in Java or C++, and the ability to work effectively in another systems/services language
• Experience designing and debugging APIs, protocols, client libraries, or distributed services
• Strong fundamentals: data structures, concurrency, asynchronous programming, networking, and failure handling
• A track record of comprehensive testing — unit, integration, compatibility, and performance
• Experience with production CI/CD, release processes, and engineering quality controls
• Working knowledge of SQL
• Comfortable with AI-assisted development workflows — using modern AI tools productively while critically validating their output
• Clear written and verbal communication in a distributed engineering environment; English Upper-Intermediate or higher (B2+)
• Availability to work EU business hours shifted 2–3 hours later for daily overlap with US West Coast mornings

Desired Skills

• JDBC, ODBC, ADBC, or database-driver development experience
• Apache Arrow (including Arrow Flight)
• SQL engines, databases, or data platforms
• Source-connector development for databases, warehouses, or SaaS systems
• MCP or agent-tool integrations
• OAuth, OIDC, TLS, and enterprise authentication flows
• Cross-platform native build, packaging, and release experience
• BI-tool interoperability (Power BI, Tableau) and partner collaboration
• Observability and production diagnostics
• Open-source contribution experience

Details

• Engagement: Long-term contract
• Location: Europe (EU / EEA / UK), remote
• Working hours: EU business hours, shifted 2–3 hours later for daily overlap with the US West Coast team
