🌊 Data Engineer: Build the Lakehouse Behind Millions of Players

Adaptiq × a major online gaming operator

The challenge:

Our client, a major online gaming operator, is building a next-generation account management platform as a greenfield project. It runs in a highly regulated, high-volume environment where availability, sub-second performance, data integrity, and full auditability are non-negotiable, including during extreme traffic spikes.

Every transaction becomes data, and that data has to be right. How do you ingest it without losing or duplicating a single event? How do you keep it fresh and reconciled with source systems? How do you store years of history so it’s cheap to keep, fast to query, and GDPR-compliant? These are the questions you’ll answer.

Your role:

We’re looking for a hands-on Data Engineer to build scalable, reliable data infrastructure and production-grade pipelines, with a strong focus on data quality, integrity, and performance.

You’ll own the design, implementation, and operation of the data lake and lakehouse architecture, including key technical decisions. You’ll define how data is stored, partitioned, processed, and monitored, work closely with Data Engineering, DevOps, Data Science, and other stakeholders, and help shape the platform’s long-term scalability and the data migration.

What you’ll do:

• Build and maintain a multi-layer lakehouse (bronze / silver / gold) on Iceberg or Delta, including schema evolution
• Design CDC and streaming ingestion with Kafka, Debezium, or similar, handling late and duplicate events
• Optimize data layout in cloud object storage: partitioning, compaction, file sizing, query performance
• Define retention, archival, immutability, and GDPR-style deletion processes
• Ensure data freshness, quality, and consistency; detect drift and reconcile with source systems
• Implement governance: metadata, lineage, access controls, PII protection, encryption, audit trails
• Monitor pipelines and drive resolution of data anomalies

• Collaborate with Analytics, Finance, and Compliance on requirements, migration, and architecture

   

What you bring:

• 5+ years in data engineering with large-scale data lakes or lakehouse environments
• Production experience with cloud object storage (AWS S3 or equivalent) and an analytics platform such as Snowflake, Databricks, or BigQuery
• Hands-on expertise with Iceberg, Delta, or Hudi, plus solid knowledge of partitioning, file layout, and query optimization
• Experience building CDC and streaming pipelines (Kafka, Debezium, or similar)
• Strong SQL, data modeling, and understanding of relational and transactional data
• Experience with data quality, monitoring, and governance: lineage, access control, PII handling, retention
• Python and workflow orchestration (Airflow or Dagster)

• Ability to own technical decisions and clearly explain trade-offs

   

Bonus points:

✦ Financial, transactional, or ledger data
✦ Regulated or audit-heavy environments: fintech, gaming, banking, payments
✦ Large-scale data migration projects

🎰 Senior Java Engineer: Build the Wallet Behind Millions of Players

Adaptiq × a major online gaming operator

The challenge:

Picture a platform where millions of players hit "play" at the same moment, every action moves real money, and the answer must come back in under a second. Now picture building it from scratch.

That's the PAM (Player Account Management) platform: real-time financial transactions, strict regulation, zero tolerance for lost cents, and traffic spikes that would make most systems sweat. No legacy code to inherit. Just a blank page and hard problems.

Your role:

You'll design and build the core backend of the platform and own your features end-to-end: from RFC to production monitoring. You'll work side by side with Principal Engineers, with real autonomy and real influence on the architecture.

What you'll do:

• Build services in Java 17+ / Spring Boot for wallets, ledger, payments, bonuses, and account state
• Create REST APIs and Kafka-based event flows for frontends, ops tools, and partners
• Make correctness non-negotiable: idempotency, clear transaction boundaries, failure handling, solid testing
• Bake in compliance: KYC/AML, responsible gaming, audit trails
• Keep production healthy with metrics, tracing, alerts, and on-call
• Shape the platform through RFCs and code reviews, and mentor teammates
• Work with AI-assisted tools daily

• Help migrate live from the existing third-party platform (parity testing, data validation, cutover)

   

What you bring:

• 5+ years in backend engineering, with strong Java 17+ and Spring Boot
• Experience with high-integrity transactional systems: payments, wallets, billing, banking, e-commerce, or gaming
• Deep PostgreSQL (or similar) knowledge: schema design, ACID, locking, tuning
• Event-driven architecture experience (Kafka, RabbitMQ), including idempotency and retries
• Automated testing as a habit: unit, integration, contract
• Hands-on production experience with containers, CI/CD, observability, and incident troubleshooting
• Solid grasp of multi-threading and fault-tolerant design

• Good English and comfort working across time zones

   

Bonus points:

✦ iGaming, betting, or fintech background
✦ Kubernetes and AWS (VPC, IAM, EKS, auto-scaling)
✦ Compliance-driven development experience
✦ Agentic development workflows
