Jobs at Djinni

We are looking for a Mid Data Engineer in Kraków, Poland who will own the company data lake — the system of record for millions of financial events a day (bets, wallet movements, live odds) across 12M+ active users. You decide how that data lands, is stored, retained, and governed on S3 + Snowflake/Databricks, so analytics, finance, and regulators all see accurate, reconciled data with zero drift from source.

Domain: Regulated iGaming / wallet & ledger data. Audit-heavy: regulators, finance and analytics all consume the same tables. Millions of financial events per day, terabyte-plus scale.
 

What you'll be doing:

• Own the lakehouse architecture: bronze/silver/gold layers, Iceberg/Delta tables, schema evolution.
• Land operational data via CDC streaming (Kafka, Debezium), handling late and duplicate events.
• Design data layout for speed and cost: partitioning, compaction, file sizing, query performance on Trino/Athena/Snowflake.
• Own retention and archival: storage tiering, regulatory retention, immutability, GDPR deletion.
• Guarantee correctness: freshness SLAs, drift detection, reconciliation against the source wallet and ledger systems.
• Own governance: catalog and lineage, row/column access control, PII masking, encryption, audit trails.
• Monitor ingestion health, data anomalies, and cloud storage/compute spend.
  
  Must-have:
• 3 years' experience in hands-on delivery within that architecture — pipelines, ingestion, models, monitoring
• Lakehouse architecture — bronze/silver/gold layering, an open table format (Iceberg, Delta, or Hudi), schema evolution.
• Data layout & query optimization at TB+ scale — partitioning, compaction, file sizing, query performance on Trino/Athena/Snowflake.
• Cloud lakehouse/DWH in production — Snowflake, Databricks, or BigQuery.
• CDC & streaming ingestion — Kafka + Debezium or equivalent; late, duplicate and out-of-order events.
• Strong SQL and data modeling — enough relational grounding to reason about the OLTP systems you capture from. Critical for financial ledgers.
• Correctness — freshness SLAs, drift detection, reconciliation against source wallet/ledger systems.
• Governance — catalogs, lineage, row/column access control, PII masking, retention, GDPR deletion.
• Cloud object storage — S3 or GCS, plus storage tiering and archival.

• Python and an orchestrator — Airflow or Dagster, as tools.

   

  Location & work model:

• Kraków, Poland. Hybrid — 2 days per week from the office.

• Build tooling that leverages browser internals and the Chrome DevTools Protocol (CDP).
• Use Claude and agentic workflows as part of your everyday development process to speed up development, testing, and debugging.
• Investigate and resolve complex issues that surface only in customers’ environments.
• Take on independent research tasks, from evaluating browser automation approaches to improving performance on mobile platforms.
• Collaborate with engineering, product, and QA to ensure technical quality and smooth delivery.

Requirements

• 5+ years of hands-on industry experience developing and maintaining production-grade software in a product environment.
• Strong proficiency in JavaScript and TypeScript.
• Experience with Node.js and NPM tooling.
• Familiarity with test automation frameworks or the Chrome DevTools Protocol.
• Hands-on experience using AI-assisted development tools in your daily workflow to accelerate development.
• Proven experience working in hybrid or extended teams, collaborating day to day with engineers in another country.
• Excellent written and spoken English, with clear, confident verbal communication.
• A true team player who communicates openly and takes shared ownership of results.
• Based in Warsaw and able to work from the office 3 days per week.

Will be a plus:

• Understanding of browser architecture (DOM, rendering, caching).
• Experience with MCP, LLM agents, or tool-calling integrations.
• Contributions to open-source projects and developer communities.
  What we offer:
• - A friendly environment where you can reach your full potential and grow your career.
• - A long-term, full-time B2B contract with a Polish company.
• - Paid vacation days, paid sick leave, and paid days off on all Polish public holidays.
• - Hybrid work in Warsaw: 3 days per week in the office, the rest of the time remotely.

  • 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.

Project details

We are looking for a Senior Full-Stack Engineer to join the team behind an AI-powered autonomous testing platform, built by a global leader in AI-powered test automation whose products are trusted by enterprises and startups worldwide, including many of the world’s largest companies.

This role involves end-to-end feature development across a TypeScript stack, from the Node.js backend to the React frontend, with an AI-first approach at every step of the development workflow. You’ll own features from technical design to production, work closely with Product and Design, and collaborate daily with the client’s engineering group as an integrated member of a hybrid team.

About the product.
The team builds an AI-powered platform that lets teams create, run, and maintain end-to-end tests with minimal manual effort. Instead of writing test code, users simply provide a URL: the platform crawls the application, automatically generates visual and functional tests, and organizes the results in a centralized dashboard.

Key responsibilities

• Design, build, and ship product features end to end across the TypeScript stack (Node.js and React).
• Own features from technical design through development, testing, release, and production monitoring.
• Think like a product owner: dig into the “why” behind features, balance user needs with technical tradeoffs, and take real ownership of the product experience.
• Work closely with Product, Design, and your teammates in Israel to turn requirements into clean, well-architected solutions.
• Contribute to architecture discussions, code reviews, and engineering best practices.
• Use Claude and agentic workflows as part of your everyday development process to move faster, and help build shared AI automations for the team.

Requirements

• 5+ years of hands-on software engineering experience in SaaS or product-driven companies, delivering features as a full-stack engineer on cross-functional product teams.
• 3+ years of production experience across the full stack with TypeScript, Node.js, and React.
• Hands-on experience using AI-assisted development tools in your daily workflow to accelerate development.
• Exceptional collaboration and communication skills, with a track record of partnering closely with product managers, designers, and fellow engineers.
• Proven success working in distributed or hybrid teams, collaborating daily across time zones (ideally with international engineering groups).
• Fluent written and spoken English, with the ability to explain complex technical ideas and tradeoffs clearly and confidently.
• A strong sense of ownership, self-direction, and an open, egoless communication style.
• Based in Warsaw and able to work from the office 3 days per week.

Will be a plus:

• Familiarity with test automation tools and frameworks (Playwright, Cypress, Selenium).
  What we offer:
• - A friendly environment where you can reach your full potential and grow your career.
• - A long-term, full-time B2B contract with a Polish company.
• - Paid vacation days, paid sick leave, and paid days off on all Polish public holidays.
• - Hybrid work in Warsaw: 3 days per week in the office, the rest of the time remotely.
