About Our Client

Our client is a leading enterprise data platform company building an open, high- performance data lakehouse for AI and analytical workloads. The platform combines an intelligent SQL query engine, an AI-ready semantic layer, and an open catalog built on Apache Iceberg — enabling Fortune 500 companies across finance, energy, manufacturing, and logistics to unify, query, and govern data at massive scale across cloud and on-premise sources.

About the Role

We are looking for a Middle Software Engineer (1.5–3.5 years of experience) to join the sustaining engineering team for the data catalog and enterprise data management layer of a large-scale lakehouse platform — the services that automate data ingestion and optimize Apache Iceberg tables for existing customers. The team's mandate is to keep these services running reliably for current clients: investigating and fixing customer- reported issues, resolving defects, addressing performance regressions, and keeping dependencies and security patches current. This is a maintenance and support role, not a feature-development role.

This is a backend Java role in a multithreaded, distributed environment where stability and availability for production customers are the baseline expectations. You will work with hands-on mentorship from senior engineers and in daily collaboration with US-based engineering leads and support teams.

Responsibilities

• Investigate, reproduce, and fix customer-reported issues and defects in the catalog and data-management services (Java)
• Diagnose production problems from logs, metrics, and thread or heap dumps, and work with support teams and solution architects on customer escalations
• Address performance regressions and stability issues in multithreaded, distributed services
• Keep the services current: dependency and library upgrades, security patches, and compatibility fixes
• Write regression tests and small supportability improvements (logging, metrics, diagnostics) so issues are easier to catch and triage next time
• Take part in code reviews and follow the team's release and hotfix process
• Track and apply relevant upstream fixes from the Apache Foundation open-source projects used by the platform

• Communicate status, root causes, and blockers clearly in daily syncs with US-based engineering leads

   

Required Qualifications

• B.S. or M.S. in Computer Science or a related field
• 1.5–3.5 years of professional software engineering experience, preferably in backend or data-intensive systems
• Strong Java programming skills: solid command of the language, the JVM ecosystem, and standard tooling (Maven or Gradle, JUnit)
• Comfortable debugging and supporting production systems — reading logs and stack traces, reproducing issues, and finding root causes
• Good grounding in data structures and algorithms
• Working knowledge of multithreaded and asynchronous programming in Java (java.util.concurrent, executors, futures) and the motivation to go deeper
• Care for engineering quality — tests, code reviews, and an understanding of why availability, resiliency, and zero-downtime upgrades matter
• Comfort with a fast-moving environment, ownership of your work, and an eagerness to learn from and be mentored by senior teammates
• Comfortable with AI-assisted development workflows — using modern AI tools productively while critically validating their output
• English Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team

• Availability to work EU business hours shifted 2–3 hours later for daily overlap with US West Coast mornings

   

Desired Skills

• C++ experience — reading or writing performance-sensitive native code
• Exposure to database internals or query planning
• Familiarity with distributed systems concepts: concurrency control, data replication, storage systems
• Apache Iceberg or other open table formats (Delta Lake, Hudi)
• Messaging systems: Kafka, NATS, or cloud pub/sub services

• Contributions to open-source projects (Apache projects especially valued)

   

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

📍 Location: EU-based
💼 Cooperation type: Full-time

Phenomenon Studio is a boutique product design and development agency founded in 2019. We work with teams who’ve outgrown what they’ve built — from venture-backed startups to established market leaders — and own the work end to end: strategy, design, development, and post-launch.

The team of 70+ senior specialists is based in Europe, with entities in the USA, Estonia, and Switzerland, serving SaaS, Fintech, Healthcare, and EdTech. Across 120+ launches, clients have raised $500M+. Phenomenon is HIPAA-compliant, Nielsen Norman Group UX certified, and a Webflow Experts partner, holding a 5.0 rating on Clutch — and most clients come back for a second project.

We’re looking for a Senior Product Designer who treats a brief as a hypothesis rather than a specification.

Advantages of the role

• You own complex projects end to end. You don’t just do one part of someone else’s plan — you find the problem, decide what to do, and take responsibility for the result
• You’ll talk directly with the client to understand their needs and expectations, then present your solutions and stand behind them
• We submit product work to awards that judge the thinking, not the surface — Red Dot, UX Design Awards
• A design community of 30+ designers who give honest feedback, share second opinions, and help you think through decisions — people who’ve been in your shoes
• You’ll have a personal mentor to support you. Down the line, you’ll get to be that person for someone else

Requirements

• 5+ years of commercial product design experience, a substantial part of it in an agency or outsourcing setup
• Ability to take a project from 0 to 1 as the only designer on it
• Experience across both web and mobile products (iOS, Android)
• Strong visual craft — work that carries a brand and holds up in use, not just structurally sound layouts
• Experience optimising user journeys against metrics: engagement, conversion, retention
• Experience with UX research and behaviour analysis tools (Hotjar, Amplitude, Google Analytics, etc.)
• Proficiency in Figma (tokens, components, variables, auto-layout)
• Proficiency in modern AI tools for building live demo prototypes and products — Claude Code, Cursor, and similar — and using AI in your workflow without losing quality
• Strong spoken English (B2+ level). You’ll run calls, present and defend solutions, and handle client disagreements directly, alongside the PM.
• A case showing measurable impact on product metrics — required, either in your cover letter or already in your portfolio

What the role actually asks of you

• Identifying the real problem, even when it’s not what the client originally asked for — and being able to explain its importance.
• Adapting the process to the project instead of running the framework to the end
• Identifying the outcome your work should produce, and how anyone would know you met it
• Deciding without complete information — judging business, tech, and budget factors yourself, and acting on it
• Explaining the reasoning behind your solutions to the client, not just presenting layouts

This role is probably not a fit if

• Your answer to “why is it built this way?” is “that’s what the client / PM / Lead asked for”
• You need a detailed PRD or spec before you can start working
• You pass decisions upward instead of bringing a recommendation and the reasoning behind it
• Your case studies show only deliverables — flows, wireframes, a design system, not your reasoning, decisions, or the results.

What we offer

• Remote work format and flexible schedule
• Autonomy in work, opportunity to build processes, and grow within the company
• Individual development plan and annual performance review
• Workshops and playgrounds for continuous learning
• Compensation for subject-matter training
• Corporate English classes
• Access to IT Loyalty Club
• Accounting support
• 18 working days of annual leave
• 7 working days of sick leave and 7 working days of unpaid leave
• All national public holidays off

Recruitment process: Recruitment interview — Technical interview — Final interview

• Service Delivery: run shift rotas for 24/7 VIP coverage, allocate the player portfolio across your team, and lead the daily huddle at the start of every shift.
• Quality Assurance: sample and score 5–10 interactions per manager weekly; run monthly calibration sessions to keep the whole team's standards aligned.
• Crisis & Escalation: personally step in on account-closure threats, high-value disputes, and sensitive complaints — the senior voice VIPs get put through to when it matters.
• Tier-1 Relationships: personally manage our top 10–20 VIP accounts — birthdays, milestones, and the kind of recognition that keeps them loyal.
• Strategy Execution: translate the Head of VIP's campaign calendar into weekly team targets, and make sure every offer goes out accurately and on time.
• Voice of Customer: collect and categorize player feedback, and report themes monthly to the Head of VIP and Product team.

What We're Looking For

• Experience leading a frontline team in VIP account management, high-touch customer service, or player relations — ideally in iGaming/gambling.
• A genuine coach: comfortable giving real-time feedback, running QA calibration, and developing people, not just monitoring them.
• Calm under pressure — you can de-escalate a VIP threatening to close their account without losing your composure or overpromising.
• Operationally sharp: rota planning, SLA management, and payroll/KPI validation are second nature, not an afterthought.
• Working knowledge of responsible-gambling obligations and how they apply to VIP servicing in T1/T2 markets.
• 2+ years in a team-leadership or senior account-management role within iGaming, hospitality VIP services, or a comparable high-touch environment.

Why Join Us

• Real ownership of the player relationships that matter most to the business, with a direct line to strategic leadership.
• Competitive salary and performance-based bonus structure.
• Remote-first, internationally distributed team.
• Clear growth path — this is the operational proving ground for future Head of VIP talent.

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.

🌍 Why You Should Join Us

• Competitive Compensation: Enjoy a highly competitive salary and performance-based bonuses.
• Remote Flexibility: Work from anywhere as part of an international and geographically diverse team.
• Professional Growth: We invest in your career development with ample opportunities for learning and growth.
• Exciting Challenges: Join a forward-thinking, fast-growing company at the forefront of the iGaming industry.
