Jobs at Djinni

NexaPay (nexapay.one) is an Estonian fintech company in the payments space. Our payment gateway allows merchants to accept Visa, Mastercard, Apple Pay and Google Pay, and receive settlement in USDC. We work with B2B clients worldwide.

We're scaling and looking for a developer who can build high-quality web interfaces fast, making active use of modern AI development tools. We need someone who can take an idea to a working, well-designed product in a short time — and who genuinely understands what they're building.

What you'll do
— Build and develop the company's websites and landing pages, from mockup to production
— Create internal interfaces and panels for the team
— Maintain, improve and update existing pages and functionality
— Test ideas quickly: build prototypes and take the successful ones to completion
— Own the quality: responsiveness, load speed, correct behaviour across all devices

What matters to us
— A strong sense of modern UI/UX: you build interfaces that look polished and expensive, not templated. This is a key requirement
— Portfolio required: live links to websites or interfaces you've built
— Confident use of AI development tools (Claude Code or similar) — and a clear sense of where they can be trusted and where your own review is needed
— Real understanding of code, not just generation: project structure, working with repositories and Git, deployment, reading and editing existing code, a working grasp of backend and APIs
— Experience with a modern frontend stack (React/Next.js or similar)
— English at B2+: documentation, tools and part of our communication are in English
— Independence: the ability to take a task, see it through, and propose a better solution
— Attention to detail: this is fintech, where accuracy and reliability matter more than speed

Nice to have
— Experience in fintech, SaaS or with payment integrations
— Basic understanding of web application security
— Experience working with analytics and SEO requirements at the markup level

Hiring process
Portfolio review → interview → a test task

Schedule
Full-time, 9:00–19:00 Estonian time (EET), fully remote.

What we offer
— Competitive compensation, paid in crypto
— Fully remote work
— Freedom in technical decisions and a fast cycle: your changes reach real clients immediately
— An international fintech product that's actively scaling
— Room to grow with the company

Send your CV along with links to 2–3 things you've built — that matters more to us than formal experience.

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

Team Lead — VIP Relationship & Retention

Reports to: Head of VIP Department 

Direct reports: VIP Managers, Pre-VIP Managers, VIP Chat Managers 

The Role

We're looking for a hands-on, player-first Team Lead to run our VIP service desk day to day. You'll lead a team of VIP, Pre-VIP, and Chat Managers, personally own our highest-value player relationships, and turn the retention strategy set by our Head of VIP into flawless execution — every shift, every escalation, every offer delivered right, to the right player, at the right time. If you love coaching people, solving problems live, and being the calm voice a VIP trusts when things get tense, this is your seat.

What You'll Own

• Team Leadership: hire, onboard, and performance-manage 6–8 VIP/Pre-VIP/Chat Managers — weekly 1-on-1s, monthly scorecards, real-time coaching on live interactions.
• 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.

Ready to take your VIP expertise to the next level? Apply now and help us redefine the VIP experience, shape the future of player engagement, and make a lasting impact in the iGaming world.

 Tech Lead / Python AI Engineer / Engineering Lead / AI Architect.

Ideally, we would like to find someone based in Western Ukraine.

Across our practices, AI experimentation is organic: agents and accelerators get prototyped, they work, and they find their way to the teams who need them.

Working is not the same as dependable, tested, hardened, properly deployed, and fit for a regulated client. Closing that distance and turning experimentation into an engineering discipline is the job.

You will build and lead our AI engineering team: you, a Senior Engineer and a DevOps Engineer, and own the path from idea to production across every asset class.

You will work with SMEs within the practices to bring prioritised pilots into products that deliver return. You will be the final technical decision-maker on what ships. Roughly two-thirds of your week will be hands-on: architecture, coding and code review. The rest will focus on direction, hiring and the operating model.
 

Key Requirements

We are looking for someone who:

• Has strong experience building and owning products, rather than only completing technical tasks within outsourcing projects.
• Has 8+ years of engineering experience.
• Has strong Python experience, including production systems where Python was the primary language.
• Has strong Azure expertise and experience with production Azure workloads.
• Has hands-on experience with AI/LLM and agentic systems.
• Has experience taking products or platforms from architecture through production and ongoing operation.
• Has a player-coach background — able to lead engineers while remaining hands-on technically.
• Has strong English and communication skills.

Has experience working with regulated environments and implementing security/governance requirements in practice.

You will not be post-technical in this role.

• Responsibilities
• Own the AI delivery operating model and the path from prototype to production — from intake and qualification through build, hardening and rollout across accelerators and client-facing IP.
• Build and lead the AI engineering team: hire two engineers, set standards, review code, unblock the team and support their growth.
• Work with SMEs across practices to design, build, deploy and maintain applications.
• Personally build, ship and harden agentic solutions and own the assets you oversee.
• Own architecture and production standards across solutions, including solution architecture, infrastructure, model selection and validation.
• Turn governance into engineering through policy-as-code, guardrails, evaluations and release gates running in the pipeline.
• Implement controls suitable for regulated clients without unnecessarily slowing down development.
• Embed AI capabilities across practices by working with automation, application engineering and consulting SMEs to create a path from prototypes to production.
•  
• What Would Set You Apart?
• Claude Certified Architect (Foundations or Professional).
• Microsoft Agentic AI Business Solutions Architect (AB-100).
• LLM or agentic systems already taken to production.
• Experience deploying accelerators or productised IP across multiple clients.
•

Our client, a US healthcare nonprofit, is building a clinical application that turns AI-generated risk predictions into timely action. Frontline and clinical staff get alerts on their phones and tablets when a participant is identified as being at elevated risk. They can review the participant's recent history and record the actions they took, while supervisors monitor follow-ups and manage escalations.

The product handles protected health information (PHI), runs on Microsoft Azure and is built with an AI-first approach, so you'll use AI coding tools as part of your daily workflow.
