What We Offer

• 100% remote work opportunity and flexitime - choose working hours between 8:00-20:00 Kyiv time.
• Personal Growth Budget in USD (Travel, Health & Psychotherapy, Sports, Education & Training, Software, Work Equipment).
• Competitive compensation in USD with regular salary reviews.
• Paid vacation, holidays, and sick leave.
• Continuous professional growth through mentorship, feedback, and knowledge sharing.
• English Speaking Club with a native speaker.
• Access to AI tools, including coding assistants for engineers and LLM subscriptions for non-technical specialists.
• Projects with clients across Europe and North America across FinTech, Logistics, Hospitality, E-commerce, Legal, Music, and other industries.
• Transparent processes, flat management structure, and a supportive team culture.

About the Role

• We are hiring a Senior Full-Stack Engineer to become one of the strongest technical contributors on the team.
• The single most important thing we’re looking for is experience scaling a SaaS product. We want someone who has already seen what happens as a live platform grows: increasing complexity, technical debt, scaling bottlenecks, evolving data models, unreliable integrations, and engineering decisions that worked at one stage but became expensive at the next.

• This is a hands-on senior engineering role with strong technical leadership expectations. You will design and write production code, own substantial systems end to end, influence architectural decisions, challenge technical direction when needed, and raise the engineering level of the people around you.

   

Project

• FinTech SaaS platform built for the restaurant and hospitality industry. Our products handle tip pooling and payouts, payroll, reporting and compliance, labor and operational data, and integrations with the systems hospitality businesses already use. The platform is live, serves thousands of customers and moves millions of dollars.

   

Required Hard Skills

• Several years operating at Senior Engineer level on a SaaS product that grew significantly while you were there. You have seen a system become meaningfully bigger and understand the problems that tend to arrive next.
• Strong Python and Django / Django REST Framework experience, or deep experience in a closely comparable backend stack.
• Strong React and TypeScript experience, with the ability to work effectively across backend and frontend when required.
• Strong PostgreSQL and data modeling skills. You should be comfortable designing schemas that can evolve as the business grows into new products and safely changing them once they contain production data.
• Production experience with asynchronous and distributed workloads using Celery or comparable technologies.
• Strong understanding of API design and third-party integrations, including failure handling, retries, idempotency, data consistency, reconciliation, and situations where the system on the other side is unreliable or outside your control.
• Strong understanding of software architecture and the ability to make pragmatic architectural decisions inside a large existing codebase rather than only designing systems from scratch.
• Experience identifying and addressing performance, scalability, reliability, and maintainability problems before they become critical.
• Strong testing practices and experience safely evolving systems that must remain operational while they are being changed.
• Production experience with Docker, CI/CD, monitoring, error tracking, and observability. 
• Strong Linux knowledge. 
• Sound judgment about technical debt: knowing the difference between an acceptable shortcut and one that will create significant problems later, and being able to improve a system while it remains in production.
• Everyday experience with using AI agents for work (Claude Code or Codex). Familiar with configuring AI toolset, understanding pros and cons of modern AI.

Current Stack

• Django / DRF, PostgreSQL, Redis, Celery, Docker, Traefik, Datadog, Sentry, Mailgun, GitHub Workflows.
• Next.js, MUI, TanStack Query, React Hook Form, Zod, Vitest.

Nice to Have

• FinTech or financial systems experience, particularly payments, payouts, ledgers, reconciliation, payroll, banking, audit trails, or other systems where financial correctness matters.
• Experience with restaurant or hospitality technology, including POS, scheduling, workforce management, payroll, or similar systems.
• Experience with high-volume or business-critical third-party integrations.
• Experience improving a system with meaningful legacy code or technical debt while the product remained actively developed.
• Experience with multi-tenant SaaS architectures.
• Experience improving engineering practices across a team rather than only within your own work.
• Experience as a Senior Engineer in a company of roughly 20–200 people, where your role included helping decide what technical work actually mattered.

Required Soft Skills

• Ability to take technical ownership beyond your own tickets and think about the health of the product and engineering system as a whole.
• Strong engineering judgment and the confidence to challenge technical decisions constructively, including decisions made by Staff Engineers and engineering leadership.
• Comfort with ambiguity. Problems will not always arrive fully specified, and part of your job is asking the questions that make them clear before code gets written.
• Ability to explain complex technical trade-offs clearly to engineers, Product, and non-technical stakeholders.
• A strong teaching mindset. You explain your reasoning, document important decisions, review code seriously, and make the engineers around you better rather than becoming the only person who understands a difficult system.
• Comfortable taking leadership during difficult technical situations without waiting for someone else to define every step of the solution.
• Strong written communication and self-direction. The team is distributed across Canada and Europe with limited live overlap, so you need to communicate clearly asynchronously and drive your own work.
• Fluent English, written and spoken.

Key Responsibilities

1. Own substantial systems end to end

• Take meaningful problems that have been identified but not fully solved and work with Staff Engineers and Product to determine the right technical approach.
• Own complex initiatives from problem definition through design, implementation, migration, testing, rollout, and production monitoring.
• Design not only for the expected path, but also for what happens when something goes wrong in production.

• Remain responsible for the systems you build once they are carrying real customer data and real money.

   

2. Help strengthen the architecture of a growing product

• Work closely with Staff Engineers and the VP of Engineering on architectural decisions and technical direction.
• Understand the existing architecture and identify where today’s decisions may create tomorrow’s problems.
• Identify areas where the platform may struggle as product complexity, integrations, customers, data volume, and transaction volume increase.
• Challenge architectural decisions constructively when you see a better approach.

• Help evolve the architecture incrementally through small, safe improvements rather than unnecessary rewrites or over-engineering.

   

3. Protect correctness, reliability, and engineering quality

• Treat financial correctness as a first-class engineering concern.
• Design for reconciliation and auditability: how we prove a number is correct, understand how it was produced, and detect discrepancies before customers do.
• Use Datadog, Sentry, logs, production data, and other signals to identify recurring problems and their root causes.
• Improve observability, error handling, testing, deployment safety, performance, and operational reliability.

• Make sure recurring production problems are solved systematically rather than repeatedly patched.

   

4. Own technically difficult areas of the product

• Lead work involving complex third-party integrations, asynchronous workflows, data synchronization, reconciliation, migrations, and failure recovery.
• Design systems that behave predictably when external APIs fail, requests are duplicated, jobs execute late, or data arrives in an unexpected state.
• Work closely with Product to make technical feasibility and engineering constraints visible before implementation begins.

• Help break large technical initiatives into safe, incremental pieces that can be built, migrated, and released without unnecessarily putting the existing platform at risk.

   

5. Make the case for important technical work

• Identify technical debt, platform investment, reliability work, and architectural improvements that may not naturally appear on the product roadmap.
• Distinguish between debt that can safely remain and debt that is materially affecting reliability, engineering speed, or future product development.
• Make the business and technical case for that work using evidence rather than engineering preference alone.

• Help sequence improvements so they support product development rather than competing with it unnecessarily.

   

6. Raise the level of the engineering team

• Be a strong technical reference point for other engineers.
• Review architecture, designs, and pull requests with a focus on correctness, reasoning, and long-term maintainability.
• Explain why you would make a decision differently rather than simply leaving a verdict.
• Mentor engineers through reviews, pairing, technical discussions, and example.
• Document important knowledge and decisions so understanding stays with the team rather than with one individual.

• Take leadership when a difficult technical problem crosses multiple areas or engineers.

   

7. Remain hands-on

• Design and write production code across the backend and frontend.
• Take direct ownership of technically difficult or risky work when appropriate.
• Debug difficult production issues and establish their root causes.
• Read and understand the existing codebase before changing it.

• Build enough direct knowledge of the platform to ensure your technical decisions are grounded in how the system actually works.

   

Who this position is not for

• This is not a role for someone whose definition of seniority is simply delivering more complicated tickets. 
• If you prefer receiving clearly defined tickets and technical solutions and then implementing them, this role will probably be frustrating.
• It is not a management role. You won’t have direct reports or headcount responsibility. Leadership here comes through technical ownership, judgment, mentoring, reviews, and influence.
• It is also not a Staff Engineer role. Our Staff Engineers and VP of Engineering set the overall technical direction and architecture. You will help shape that direction, challenge it when needed, and fully own the design and implementation of substantial systems within it.
• It is not a greenfield role. You will be joining a live platform with thousands of customers and a roadmap that does not pause while technical improvements are made. Much of the work involves understanding existing systems, migrating them safely, and improving them incrementally rather than replacing them.
• If you naturally ask what happens when the system gets significantly larger, how it fails, how we know the data is correct, and what today’s shortcut will cost us a year from now, you’ll recognize the work.

Things You Should Know Before Applying

• The engineering challenge is no longer simply building features quickly. It is continuing to ship while improving reliability, scalability, architecture, and the technical foundation required for significant year-over-year growth
• There is technical debt. Part of your job is determining which debt actually matters, making its impact visible, and helping address it without stopping product development.
• Requirements will sometimes be incomplete. We expect you to help shape the solution rather than wait for perfect specifications.

• You will be expected to disagree when necessary, propose better approaches, and explain the reasoning behind them.

 We're Hiring: Web Scraping Support Engineer (Remote)

Hello everyone! Massive is looking for a Web Scraping Support Engineer to join our fully remote team. If you dream in selectors, wake up parsing HTML, and genuinely enjoy helping people solve gnarly data extraction problems — this one's for you.

 What is Massive?
Massive is an infrastructure company powering data-driven innovation at scale. We operate a global proxy network, build managed APIs for search engines (SERP), and Web Unblocking API to bypass anti-bot measures for large-scale data collection and processing.

 Why This Role Is Different
Most support roles are reactive. This one isn't. You're the person customers trust when their scraping pipeline breaks at 2 AM, when a target site changes its structure overnight, when nothing works and nobody knows why. You don't just answer tickets — you solve problems that other engineers can't.

 Who We're Looking For
 

• Troubleshoots in Their Sleep: Broken selectors, anti-bot walls, rotating proxies, CAPTCHAs, headless browser quirks — you've seen it all and you fix it before your coffee gets cold
• AI is your best friend - you know how to leverage AI to be 10X faster and more productive
• Customer-Obsessed & Likable: You're the person customers ask for by name. You explain complex concepts in plain language and people genuinely enjoy working with you
• Can Scrape Anything, Anywhere: SPAs, paginated APIs, rate-limited endpoints, geo-restricted content — if it's on the web, you know how to extract it
• Consumes Data for Breakfast: You think in JSON, dream in XPath, and get excited about a well-structured dataset
• Relentlessly Organized: Your support board is pristine. Every ticket triaged, every follow-up tracked, every edge case documented. Nothing slips through — ever
• Curious Builder: When you notice the same issue three times, you don't just fix it — you automate the solution so it never comes back

 What You'll Be Doing

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.
