We're looking for a Solution Expert to join our Client Support team and become the go-to person our clients trust when something isn't working the way it should.
 

You'll own a queue of cases from the moment they land to the moment they're resolved, working across our support portal, email, and phone. Our platform runs ticketing and live event management, so if you've worked in that world before, great, and if you haven't, we'll teach you. What matters more is that you're genuinely curious about how things work, patient enough to walk someone through a fix, and quick enough to think on your feet when the queue gets busy.
 

What you'll do

• Get to know the platform inside and out, so you can troubleshoot with confidence instead of guessing.
• Triage incoming cases and turn client questions into clear, practical solutions, explained in plain language whether you're writing an email or talking someone through it live.
• Dig into reported issues: reproduce the behavior, find the cause, and either fix it or hand it off to a Technical Solution Expert with a clean, complete summary.
• Run walkthroughs and consulting sessions when clients are learning something new, and keep them in the loop throughout the life of a case so they never have to chase you for an update.
• Add what you learn to the team's knowledge base and training materials, so the next person doesn't have to solve the same problem from scratch.
• Notice the patterns behind recurring issues and speak up about product gaps or process fixes.
• Stay flexible around on-sales and the natural seasonality of live events, since that's when clients need you most.
   

What you bring

• Client-facing support or service desk experience, ideally at a SaaS or tech company, and a real track record of turning a confused client into a happy one.
• Strong written and spoken English, with the knack for explaining something technical without the jargon.
• A methodical troubleshooting mindset: comfortable in web applications, able to read configuration settings and make sense of error messages, and unafraid of a tricky case.
• Experience working against SLAs inside a ticketing or case management system, and the ability to juggle a queue where priorities shift by the hour.
• Comfort with Windows and/or macOS, browsers, and everyday internet tools.
• A plus if you've trained clients on software before, or if you know the ticketing and live events world already.
   

What we look for in a teammate

Technical skill gets a case solved. Attitude is what makes a team actually work. We want someone proactive and dependable, the kind of person who picks up the hard case, shares what they learned from it, and helps a teammate without being asked twice. You flag risks early, follow up before a client has to chase you, and stay steady when the queue gets loud. You're curious enough to keep learning the product and the industry on your own, and open enough to take feedback as well as give it.
 

If that sounds like you, we'd love to hear from you.

Web is where we’re building what comes next. In 2025, web grew 10x year-over-year — and by mid-2026, we’re already close to repeating that entire year’s numbers. Now we’re looking for a Head of Web Growth to join one of our Business Units and take the web even further: from a strong growth engine to the dominant revenue driver across its app portfolio.

You’ll report to the CEO of the BU and lead a team of growth managers, who are already delivering solid results. Your job is to help them aim higher and build the systems that make strong performance repeatable.

What you will do:

• Own web revenue performance across the unit and set the direction for how the team moves these numbers
• Audit current web growth processes and build the strategy from there
• Lead the shift to web-to-web as the primary growth format — scaling what works and fixing what doesn’t

• 3+ years of leadership experience managing growth teams and driving cross-functional collaboration across product, marketing, analytics, and engineering

• Deep understanding of unit economics and web growth metrics: CAC, LTV, ROAS, retention, churn, funnel conversion — and how they connect to each other
• Understanding of how LTV prediction models are built and what drives them
• Experience with payment infrastructure: you know how subscription billing works end-to-end
• Hypothesis-driven approach to growth: you build experiments, read results honestly, and iterate fast
• Sharp analytical thinking — you work comfortably with numbers, notice what others miss, and can translate data into decisions
• Solid people management instincts — you know how to develop talent
• Strong written and spoken English

What we offer:

• Results-oriented colleagues committed to scaling impactful products. Your team will help you achieve the most ambitious goals
• Remote-friendly work environment with high autonomy and minimal bureaucracy
• Competitive fixed salary+ generous performance-based bonus
• Medical insurance (depending on the location)

• Paid vacations, sick days, and other benefits

NuxGame is a B2B iGaming technology provider. We deliver turnkey casino and sportsbook platforms, game aggregation, and sweepstakes products to operators worldwide, across four product lines: Turnkey Traditional, Sweepstakes Turnkey, Game Aggregation, and Sweepstakes Game Aggregation.

Our customers are operators. Their back office teams work in our platform every day, and their players use it every time they deposit, verify their identity, or withdraw.

We are looking for a Product Manager to join our Finance Team. You will own everything on the platform that touches money, player identity, and player protection—spanning seven product domains with one dedicated engineering team behind you.

What You Will Do

• Payments and PSP
  • Own the payment roadmap across all four product lines and decide what gets built, what gets configured, and what gets refused.
  • Own the internal payment gateway as a product: integration contract, provider onboarding, error handling and retries, logs, and the tooling support uses to investigate a stuck transaction.
  • Own the technical and product side of PSP relationships and work with our PSP Manager, who owns commercial terms and provider selection.
  • Drive deposit and withdrawal conversion: cashier UX, method visibility and ordering, error minimisation, hosted versus platform side flows, retry and cascading logic.
  • Own crypto and Web3 coverage: networks, confirmations, on ramp providers, wallet based authorisation and deposits.
  • Shorten the time it takes to launch a new provider by standardising the integration, so a new PSP becomes configuration rather than custom development.
• Fraud, KYC and Compliance
  • Own the fraud and risk engine: rules and thresholds, risk scoring, verification flows, duplicate account and bonus abuse detection, manual review load.
  • Own third party KYC and AML integrations end to end, from provider evaluation and platform requirements through rollout to operators.
  • Turn licensing and jurisdictional requirements into configurable platform capability instead of per operator custom work.
  • Hold the balance between fraud prevention and conversion, and defend where you put the threshold.
• Auth and Identity
  • Own registration and login as a conversion product, including social and Web3 registration.
  • Own the relationship between authentication and verification: what a player can do before KYC, what unlocks after it, and how that differs by jurisdiction and by operator.
  • Own back office authentication, permissions, and audit logs as an operator facing product.
• Segmentation
  • Own segmentation as a shared service: how segments are defined, evaluated, and consumed across payments, limits, verification, and reporting.
  • Make it usable by operators without engineering involvement: rule builder, preview and validation before a segment goes live, predictable behaviour when several segments match one player.
  • Own the cost side of it: evaluation performance on large player bases and what happens when a segment changes mid-session.
• Reporting, Limits and Responsible Gambling
  • Own operator facing financial reporting, dashboards, and export tooling.
  • Own the limit framework (deposit, loss, wager, session) and geo blocking as jurisdiction aware, operator configurable capability.
  • Own the responsible gambling toolset and make sure it satisfies the licences our operators hold.

What We Expect From You

• You own the roadmap for your domains and you defend it. Prioritisation is your call to make and to explain, not something you escalate by default.
• You write specifications that an engineer can build from without a business analyst in between: scope and non scope, flows, edge cases, dependencies, acceptance criteria.
• You work with data yourself. You define the metric, pull the number, and check it before you act on it.
• You go deep on the technical side. You read API documentation, review integration contracts, and hold your own in a discussion with engineers.
• You design for many operators at once. Every decision is a decision about configuration, defaults, and backward compatibility, not about a single customer.
• You close the loop after release. A feature that shipped and moved nothing is not a delivered feature.

Requirements

Must Have

• 5+ years in product management, with at least 3 years owning payments, fraud and risk, or financial products in iGaming, fintech, or payments.
• Hands on experience with PSP and payment aggregator integrations: REST APIs, request and response construction, webhooks and callbacks, idempotency, status and error mapping, reconciliation.
• Practical understanding of the trade offs between hosted payment pages, iframe, and fully platform hosted cashier flows, including where PCI scope, conversion, and support load land in each.
• Experience with several payment method families: cards, e-wallets, bank transfer and local rails, vouchers, and crypto (networks, confirmations, on ramp providers).
• Experience integrating KYC and AML providers, and owning or building a rule based fraud or risk engine.
• Experience with rule based configuration and player segmentation: defining segments, resolving conflicts between overlapping rules, and giving business users a safe way to change them without a release.
• Working knowledge of the regulatory requirements affecting deposits, withdrawals, KYC, and responsible gambling in at least two or three jurisdictions.
• Data fluency: deposit success rate, approval rate by provider and method, withdrawal processing time, chargeback rate, verification funnel conversion. You can pull these yourself.
• B2B product experience. Our users are operators and their back office staff, not only end players.
• Structured written communication in English. Russian or Ukrainian for internal team communication.

Nice to Have

• Experience in a multi tenant white label platform serving dozens of operators at once.
• Sweepstakes or social casino experience, where purchase and redemption flows differ from classic deposit and withdrawal.
• Experience with payment orchestration platforms, smart routing, and cascading.
• Experience with Metabase or a comparable BI stack, and enough SQL to validate a number.
• Practical use of AI tooling in the product workflow for discovery, documentation, and analysis.

What We Offer

• Full ownership of a product area that directly moves revenue for dozens of operators, with a dedicated engineering team behind it.
• A direct line to the CPO and to top management. Decisions here take days, not quarters.
• Remote work with a distributed team, or an office in Limassol if you prefer one.
• Competitive salary, flexible hours, and paid time off.

About the Project

The team builds low-level compute kernels for inference/training of well-known LLM models, hand-optimized for a proprietary (custom) chip based on the RISC-V architecture with RISC-V Vector Extension (SIMD intrinsic extension) and a custom VCIX Coprocessors. In terms of functional scope, this is analogous to what PyTorch/Tensorflow provides (matmul/GEMM, convolution, elementwise ops, reduction, attention/softmax, quantization) — but written from scratch for a specific chip rather than routed through an existing backend.

What You Will Actually Do

• Write new compute kernels (functionally equivalent to PyTorch operators: matmul/GEMM, convolution, elementwise, reduction, attention/softmax) targeting custom RISC-V hardware.
• Implement and tune mixed-precision inference pipelines across multiple numerical formats (FP32, BF16, MXFP8, MXFP4, NVFP4).
• Investigate and improve the performance of existing kernels and how they are invoked: optimize cache vs. DRAM memory usage (memory hierarchy, tiling/blocking, prefetching, bandwidth vs. latency trade-offs).
• Optimize distributed communication for multi-device and multi-node inference.
• Partition and schedule workloads across compute cores to maximize hardware utilization.
• Fuse individual kernels into efficient end-to-end pipelines for LLM model execution.
• Write C++23 code with heavy use of metaprogramming (templates, constexpr, concepts, CRTP, SFINAE) to generate specialized code for different kernel configurations.

Required Qualifications

• Hands-on experience writing low-level compute kernels — GEMM/matmul, convolution, elementwise, reduction, or similar — regardless of whether this was for PyTorch/ATen, XLA, CUDA, ARM NEON/SVE, x86 AVX, or other hardware. The key requirement is actual kernel-writing experience, not just usage of high-level ML frameworks.
• Experience with SIMD/SIMT/vector intrinsics on any architecture (RVV, ARM NEON/SVE, x86 SSE/AVX/AVX-512) or with inline assembly, understanding how the compiler maps intrinsics to instructions etc.
• Solid understanding of memory hierarchy: cache vs. DRAM, cache lines, latency/bandwidth trade-offs, data locality, tiling/blocking for compute optimization.
• Strong interest in and willingness to optimize code for performance and memory efficiency, with the ability to identify bottlenecks and continuously improve execution speed, memory usage, and overall system efficiency.
• Strong focus on latency minimization in production inference paths — able to identify and eliminate latency-critical bottlenecks across the full execution pipeline, not just individual kernels.
• Comfortable working in a Linux-like environment for building/testing (WSL/Linux), and experience debugging without full GUI debugger tooling (log-based debugging).

Strong Pluses

• Direct RISC-V experience (ISA, RVV / custom intrinsic extensions, cross-compilation with a RISC-V toolchain — GCC/LLVM/Clang).
• Experience optimizing kernels for LLM inference/training (attention, KV-cache, softmax, layer norm, quantized matrix multiplication).
• Experience with proprietary/custom hardware (not reference architectures), including writing code for early-stage chips where tooling and debugging capabilities are limited.
• Understanding of collective communication operations, distributed training (Data/Tensor/Pipeline Parallelism).
• Understanding of floating-point formats — FP32, BF16, MXFP8, NVFP4/MXFP4 — including their trade-offs in precision, dynamic range, and performance.
• Understanding of how numerical format choice affects throughput, memory bandwidth, and training/inference numerical stability.
• Strong C++ (17/20/23) with confident use of template programming — real experience in a generic/template-heavy codebase, not just familiarity with the syntax.
