Software Development Engineer - Identity Resilience

Requirements

• At least 4 years of practical experience developing and operating production services
• Strong experience developing applications in Java or Kotlin
• Proven track record designing and implementing online services that operate at scale
• Deep knowledge of system scalability, availability, and performance, with hands-on experience diagnosing real production issues
• Strong full-stack troubleshooting skills, including networking, operating systems (Linux), and DNS, with the ability to debug cloud-based services end to end
• Experience with the AWS stack, particularly networking (VPCs, security groups), compute (EC2), load balancing (ALB, Application Gateway), CDN (CloudFront), and DNS (Route53)
• Proficiency using observability tools such as Splunk, New Relic, Prometheus, and Grafana to investigate performance regressions and operational anomalies
• Solid grasp of CI/CD methodologies and modern delivery practices
• Comfort working with AI-assisted development and analysis tools as part of daily engineering practice

What You'll Be Doing

• Own features end to end, from design and implementation through testing, deployment, and ongoing operation in production
• Investigate performance and availability across all layers of an n-tier application stack, identifying bottlenecks, latency outliers, and sources of degradation before they reach customers
• Develop high-performance, reliable, and maintainable code, whether implementing architectural improvements, adding features, writing tests, or fixing bugs
• Drive system health initiatives by analysing telemetry, profiling services under realistic load, and proposing improvements grounded in data
• Identify opportunities to improve resiliency at any layer of the stack by defining and adopting best practices, automating tests, injecting failure, and finding vulnerabilities before our customers do
• Apply AI-assisted tooling to accelerate code analysis, incident investigation, and operational workflows, while exercising critical judgment over the results
• Participate in the team's on-call rotation, contributing to incident response and to the follow-up work that prevents recurrence
