• Profile and optimize application performance across threading, I/O, memory, and caching for low latency
• Implement high-performance networking strategies to enhance packet processing and reduce latency
• Enhance Developer Experience (DX) by improving CI/CD pipelines, build systems, testing frameworks, and dev tools
• Engineer safe, testable OS and appliance upgrades with rollback and migration strategies
• Own OS startup and reliability aspects including partitioning, filesystems, GRUB, and initialization sequencing

Be Prepared — What You Bring

• Around 20 years of systems/application engineering experience with 8+ years hands-on in C and Python on Linux
• Strong in distributed systems design, including data modeling, partitioning, consistency, and performance optimization
• Proficient in Linux administration and tuning (systemd, networking, filesystems) with advanced troubleshooting tools (gdb, tcpdump, perf)
• Deep understanding of TCP/UDP protocols and scaling high-performance services
• Expertise in persistence technologies — Berkeley DB, LMDB, RocksDB, PostgreSQL — with focus on durability and recovery
• Familiar with SNMP, syslog, and OpenTelemetry for observability and system management
• Skilled in OS upgrades and startup components (partitioning, GRUB, initrd, device initialization)
• Hands-on experience in Python scripting, automation, and test tooling with strong shell and bash skills
• Excellent architectural documentation and communication skills for cross-functional collaboration
• (Nice to have) Knowledge of DDI domain, HA clustering, storage internals, security hardening, virtualization, and AI-driven observability

Be Successful — Your Path

First 90 days: Ramp on NIOS architecture and dev environment; organize direct POCs as well as conduct hands on POCs that help drive the roadmap
Six months: Lead a subsystem roadmap item (e.g., DPDK basedacceleration or Accelerating Python web applications) through design, implementation, and rollout
One year: Be the goto owner for a core platform area; set technical strategy for performance, upgrade safety, and reliability
