About this role.
FanDuel is hiring an early-career Software Engineer for its CPE Platform Session Management team in Edinburgh. The role focuses on building and improving Java-based backend services, APIs, database-backed functionality, and scalable session-management systems. The engineer will contribute to features, bug investigations, testing, code reviews, documentation, and reliability improvements with support from more experienced teammates. Candidates should have foundational backend development experience from professional, academic, internship, bootcamp, or personal projects, along with SQL, software-design, and testing knowledge. The environment is remote-first, collaborative, and designed to support technical growth and increasing ownership.

Sample interview questions
I would begin by clarifying session lifetime, consistency, security, peak traffic, and failure-recovery requirements. I would use stateless application instances behind load balancing, store session data in a scalable low-latency datastore where appropriate, and apply expiry controls, caching, monitoring, and rate limits. I would also define resilience measures such as timeouts, retries with backoff, and clear observability for latency, error rates, and session failures.
I would first assess customer impact and use logs, metrics, traces, and recent deployment history to narrow the scope. I would reproduce the issue safely where possible, form and test hypotheses, and communicate findings and mitigation steps with the team. After resolving the root cause, I would add or improve tests, monitoring, documentation, and any preventive safeguards.
A maintainable API has clear resource and error semantics, consistent naming, validation, versioning where needed, and useful documentation. Reliability also requires appropriate authentication and authorization, idempotency for retry-prone operations, sensible timeouts, structured logging, and automated tests for expected and failure cases.
I would measure first, using application metrics and database query analysis to identify whether the bottleneck is query design, indexing, data volume, connection usage, or application behavior. I would then consider targeted indexes, reducing returned fields, pagination, query rewrites, and caching for suitable read-heavy data. I would validate improvements with benchmarks and monitor for regressions after release.
I treat code review feedback as an opportunity to improve both the change and my engineering judgment. I ask clarifying questions when needed, address comments thoughtfully, and look for patterns I can apply in future work. I also aim to give respectful, specific reviews that focus on correctness, maintainability, reliability, and shared team standards.
