Hiring playbook
How to hire Scala developers
Scala engineers should balance functional programming rigor with pragmatic delivery across services and data pipelines.
Clarify service and data priorities
- Share throughput, latency, and data freshness goals along with domain constraints.
- Ask for examples balancing functional rigor with delivery pace.
Probe functional and architectural judgment
- Discuss how they design APIs, manage concurrency, and structure streaming jobs.
- Look for schema evolution strategies and contract-first thinking.
Validate reliability and observability
- Review testing approaches (property-based, contract tests), SLOs, and alerting they have implemented.
- Ensure they have run incident drills and performance tuning for JVM/cluster workloads.
Assess collaboration
- Great Scala engineers partner with product, data, and platform teams.
- Listen for clear documentation habits and cross-team communication.
How it works
Engage in three clear steps
1
Talk to a delivery lead
Align on service/data goals, governance needs, and timelines so we calibrate candidates.
2
Meet hand-selected talent
Review a shortlist of Scala seniors with the frameworks, domains, and time zones you need.
Most clients see candidates within 48 hours.
3
Start with a no-risk sprint
Kick off a scoped trial to validate collaboration, performance wins, and documentation.
Pay only if satisfied after the initial milestone.
