Note: The job is a remote job and is open to candidates in USA. White Hat Gaming is a state-of-the-art iGaming platform providing a secure, scalable and flexible modular Casino and Sportsbook Player Account Management solution. They are looking for a Platform Investigations Engineer to join their engineering team, where the role involves investigating complex technical issues and ensuring data integrity across a large-scale event-driven platform.
Responsibilities
- Own end-to-end investigation of ad-hoc technical issues raised by product, operations, or engineering teams
- Diagnose data integrity problems by tracing issues across event streams, APIs, and database layers
- Analyse Kafka event histories to reconstruct system state and identify where data diverged from expected behaviour
- Produce clear root cause analysis (RCA) documentation that explains what happened, why, and how to prevent recurrence
- Write complex SQL queries against production and staging databases to investigate data anomalies, gaps, and inconsistencies
- Understand normalised and denormalised data models, and navigate across multiple schemas with confidence
- Propose targeted data remediation scripts or operational procedures to resolve identified data issues safely
- Validate proposed fixes in lower environments before escalating to production resolution recommendations
- Use REST APIs to probe system state, trigger reprocessing workflows, and verify expected outputs
- Construct and execute API requests using Postman, and interpret responses, including error payloads, pagination, and hypermedia links
- Work with engineering and product teams to understand service contracts and identify where API behaviour diverges from the specification
- Read and interpret Scala source code to understand business logic, event handling, and data transformations — without necessarily writing new code
- Collaborate closely with software engineers to understand system internals and escalate findings with sufficient context for developers to act
- Contribute to post-incident reviews and help engineering teams understand systemic weaknesses exposed by investigations
- Produce concise, structured investigation reports suitable for both technical and non-technical audiences
- Maintain a knowledge base of known issues, recurring patterns, and resolution playbooks
- Communicate investigation status and findings clearly to stakeholders, managing expectations around timelines and scope
- Use in-house tooling to aid investigations and RCA
- Provide feedback to tool owners on your experience and provide guidance on bugs and improvements
- Apply AI (Claude) intelligently and sceptically; use it as one of the tools in your toolbox, not as a crutch or shortcut to hard-won understanding
Skills
- Solid background in software development - you should be able to think like a developer even if you are no longer writing production code
- Demonstrable experience investigating complex systems issues in a professional environment
- Strong analytical mindset with the ability to form and test hypotheses methodically
- Proficient in writing complex SQL, including multi-table joins, subqueries, window functions and aggregations
- Comfortable working with unfamiliar data models and reverse-engineering schemas without full documentation
- Experience working with relational databases (e.g. PostgreSQL, MySQL or similar) in a professional context
- Ability to reason about data consistency, referential integrity and the impact of partial failures on stored state
- Strong understanding of REST API design principles, including HTTP methods, status codes, request/response structures and authentication patterns
- Proficient with Postman or equivalent tools for constructing, executing and inspecting API requests
- Ability to interpret API responses, including error structures, timestamps and identifiers, to trace issues across services
- Working knowledge of event-driven architectures and asynchronous processing patterns
- Familiarity with Apache Kafka, including topic structure, consumer groups, offset management and the role of events in driving system state
- Understanding of the challenges inherent in distributed systems, including eventual consistency, message ordering, idempotency and failure modes
- Experience with or exposure to microservices and the ability to reason about inter-service dependencies
- Able to read and understand Scala code (Functional and OO), particularly around data transformation logic, event handlers and domain models. Writing Scala is not required
- Some knowledge of Cats Effect or ZIO
- Comfortable navigating large codebases to understand system behaviour without step-by-step guidance
- Highly curious, with a genuine interest in solving complex, ambiguous technical problems
- Rigorous and methodical, documenting your reasoning and validating findings before reaching conclusions
- Self-directed and able to navigate large, unfamiliar systems with minimal guidance
- Strong collaboration and communication skills, with the ability to work effectively alongside software engineers, data teams and product stakeholders while adapting technical findings for different audiences
- Comfortable working in uncertain environments where investigations rarely have obvious starting points, using structured problem-solving to identify root causes
- Experience with Kafka tooling such as Kafka CLI, Kafdrop, Confluent Control Centre, or equivalent
- Familiarity with monitoring and observability tools (e.g. Datadog, Grafana, Kibana) for cross-referencing system behaviour during an investigation
- Exposure to cloud infrastructure (AWS or GCP) and understanding how infrastructure-level events can surface as application issues
- Scripting ability in Python, Bash, or similar for automating repetitive investigation steps
- Experience with incident management processes, RCA frameworks, or post-mortem facilitation
