Senior Performance Engineer
Senior Performance Engineer
Location: Abu Dhabi, UAE
Join a high-growth cybersecurity scale-up in Abu Dhabi as a Senior Performance Engineer and play a critical role in shaping the performance backbone of mission-critical security products.
You will own and continuously improve the latency, throughput, and resource efficiency of a distributed platform deployed across hyperscalers, customer-managed VPCs, on-prem environments, and air-gapped infrastructure. This is a deeply technical role focused on JVM internals, distributed systems performance, and Kubernetes-native scalability - where every millisecond matters and every release must prove it can meet strict latency budgets before shipping.
Required Experience:
- 8+ years of production engineering experience with JVM-based systems, strong expertise in Java (17/21) and Spring Boot
- Deep understanding of JVM internals: garbage collection, JIT compilation, memory model, and concurrency primitives
- Strong grounding in execution models: Blocking (thread-per-request), Reactive (Project Reactor / WebFlux) and Virtual threads (Loom / structured concurrency) and ability to justify choices using benchmarks and first-principles reasoning
- Expert-level performance profiling skills using tools such as JFR, async-profiler, flamegraphs, Linux perf, eBPF, heap and allocation analysis
- Proven ability to design and run lightweight performance tests (JMH, k6, Gatling) that isolate single components and run safely in CI
- Strong distributed systems debugging skills across caching layers, connection pools, databases, networking, and JVM runtime behaviour
- Experience with capacity planning across heterogeneous environments (cloud, on-prem, customer-managed infrastructure)
- Solid Kubernetes fundamentals with an understanding of workload portability across AWS, GCP, Azure, and bare-metal
- Strong ownership mindset: comfortable taking systems end-to-end from design through production support and on-call
- Clear communicator who can translate performance findings into engineering standards, tooling, and reusable patterns
What’s in it for you?
- Ownership of key platform decisions, driving the growth and scale of critical products
- Opportunity to shape complex application and infrastructure at scale
- High autonomy within a technically strong, collaborative engineering culture
- Benefits include Visa & health insurance (for you and your family), and annual flight ticket
- Relocation package: flights and one month accommodation on arrival (for you and your family)
