Senior Software Engineer - Performance & Tooling
Aliso Viejo, CA The vision
As a
Senior Performance & Tooling Engineer , you will design and build advanced performance testing and monitoring tools. Your work will enable development teams to measure, optimize, and scale system performance across Linux, CPU, DPU, and PCIe environments. This role offers the opportunity to work on deeply technical, low-level engineering challenges that have a direct impact on product performance and reliability.
What you’ll do
Design, build, and own a
performance tooling suite
across CPU/DPU/PCIe.
Develop load generators to
saturate PCIe , NICs, and storage paths; model real-world and worst-case network/storage traffic.
Instrument the stack with Linux
perf ,
ftrace , and
eBPF
to capture timings, contention, cache/memory effects, and I/O paths.
Create
repeatable experiments
to characterize throughput, latency, jitter, tail behaviors, and scalability limits.
Build
automated
performance testbeds and CI pipelines that run on every change (smoke, regression, soak, and chaos scenarios).
Establish golden signals, SLOs, and
dashboards ; visualize trends and regressions for fast triage.
Perform deep
root-cause analysis
across userspace, kernel, drivers, and firmware; propose and land fixes.
Collaborate with
kernel ,
networking ,
storage , and
hardware
teams to optimize across the x86-64 microarchitecture and PCIe topologies.
You’re a great fit if you have
BS in Computer Science / Software Engineering, or 5+ years building
low-level
performance
and load-testing
tools .
Proficiency in one or more systems languages ( C/C++/Rust ) and scripting for automation ( Python/Bash ).
Mastery of
Linux performance monitoring & tracing
(perf, ftrace, eBPF/bcc/libbpf) in production environments.
Deep understanding of the
x86-64
microarchitecture.
Strong knowledge of
PCIe
(link training, lanes, bandwidth math, peer-to-peer, DMA) and device/driver interactions.
Comfort navigating
kernel/userspace
boundaries, syscalls, io_uring, and zero-copy I/O.
Experience building
reproducible experiments , analyzing large trace datasets, and
communicating
insights clearly.
Excitement for
open-ended problems , turning fuzzy ideas into solutions.
Curiosity
for emerging tech, including AI dev tools and introducing those that are pragmatic and boost developer velocity.
Bonus XP
DPU/NIC
experience (e.g., queues, RSS, offloads, AF_XDP, SmartNICs/BlueField).
High-performance I/O:
DPDK ,
SPDK ,
NVMe/NVMe-oF ,
RDMA/RoCE ,
iSCSI , storage stack tuning.
Observability
stacks (e.g., perf ETM, BPF ring buffers, Prometheus/Grafana, OpenTelemetry) and flamegraph tooling.
You take
ownership
of problems and feel empowered to fix them.
You
spot
gaps , draft solutions, and rally teammates without waiting for detailed specs.
You stay
calm
when priorities change, communicate trade-offs, and keep momentum.
Thrive
in fast iterative cycles with quick reviews that drive continuous improvement and progress.
Knowledge of
Japanese
language and culture is a plus.
You enjoy playing
video games !
