Meet the Team
Cisco is building a next-generation DPU-enabled networking platform for secure, high-performance infrastructure and large-scale AI clusters. Our team is responsible for designing the foundational networking, security, and programmable services that span host systems, DPUs, SmartNICs, and cloud-scale control planes. We work at the intersection of systems software, hardware acceleration, distributed security, and AI infrastructure, creating platforms that deliver line-rate performance, strong isolation, operational reliability, and simplified deployment across modern data center environments.
We are looking for a technical leader to define the architecture for host networking, DPU offload, distributed security, and programmable network services across modern DPU and SmartNIC platforms.
Your Impact
- Lead architecture for DPU-accelerated host networking, security, and network services.
- Define what runs on the DPU versus the host CPU, including tradeoffs around performance, cost, failure isolation, observability, debuggability, and operational complexity.
- Architect distributed firewalling, micro segmentation, virtual routing, service chaining, traffic steering, and line-rate policy enforcement.
- Guide platform decisions across DPU SDKs, programmable pipelines, Linux networking, control-plane services, telemetry, policy distribution, and upgrade models.
- Design APIs, policy models, configuration flows, state synchronization mechanisms, and recovery behavior for distributed networking systems.
- Build static-stability and failure-mode thinking into the architecture so the system behaves predictably during partial failures, control-plane loss, upgrades, rollbacks, and fleet-wide rollout.
- Provide technical leadership for AI cluster networking challenges, including congestion collapse, incast, ECMP imbalance, PFC/ECN behavior, noisy tenants, NIC firmware issues, switch misconfiguration, and GPU underutilization caused by network stalls.
- Align cross-functional stakeholders across hardware, firmware, product, and customer-facing teams to successfully translate complex architectural visions into shippable software.
- Elevate engineering standards across the organization through meticulous design reviews, proactively identifying systemic risks to scale, reliability, and security.
- Mentor senior engineering talent, accelerating team growth and technical depth in packet processing, host networking, and control-plane design.
Minimum Qualifications
- Bachelor’s degree with significant related experience, or advanced degree with equivalent experience in networking, systems software, distributed systems, or infrastructure engineering.
- Deep experience designing and building production networking systems, security platforms, cloud networking, host networking, or large-scale infrastructure software.
- Proficiency in systems programming experience using C/C++, Go, Rust, Python, or similar languages.
- Applied skills in Linux networking, packet processing, routing, policy enforcement, virtualization, and production debugging.
- Demonstrated ability to lead architecture across multiple teams and drive complex technical decisions from concept through production.
Preferred Qualifications
- Hands-on experience with DPU, SmartNIC, NIC offload, NPU, ASIC, or hardware-accelerated networking platforms.
- Experience with NVIDIA BlueField/DOCA, AMD Pensando, DPU SDKs, P4 or P4-like programmable pipelines, DPDK, OVS, tc, eBPF/XDP, SR-IOV, VF/PF, or kernel bypass.
- Experience architecting firewall, microsegmentation, NAT, virtual routing, VTEP, load balancing, traffic steering, service insertion, or service chaining systems.
- Proficient understanding of AI/HPC cluster networking behavior, including RDMA/RoCE, PFC, ECN, ECMP, congestion management, telemetry, and failure diagnosis.
- Experience designing distributed control planes with attention to consistency, state ownership, upgrade safety, rollback, policy convergence, and fleet operations.
- Ability to balance hardware offload, software portability, customer-visible simplicity, performance, and long-term platform maintainability.

1 paid day off for employee’s birthday, paid year-end holiday shutdown, and 4 paid days off for personal wellness determined by Cisco
Non-exempt employees** receive 16 days of paid vacation time per full calendar year, accrued at rate of 4.92 hours per pay period for full-time employees
Exempt employees participate in Cisco’s flexible vacation time off program, which has no defined limit on how much vacation time eligible employees may use (subject to availability and some business limitations)
80 hours of sick time off provided on hire date and each January 1st thereafter, and up to 80 hours of unused sick time carried forward from one calendar year to the next
Additional paid time away may be requested to deal with critical or emergency issues for family members
Optional 10 paid days per full calendar year to volunteer
For non-sales roles, employees are also eligible to earn annual bonuses subject to Cisco’s policies.
Employees on sales plans earn performance-based incentive pay on top of their base salary, which is split between quota and non-quota components, subject to the applicable Cisco plan. For quota-based incentive pay, Cisco typically pays as follows:
.75% of incentive target for each 1% of revenue attainment up to 50% of quota;
1.5% of incentive target for each 1% of attainment between 50% and 75%;
1% of incentive target for each 1% of attainment between 75% and 100%; and
Once performance exceeds 100% attainment, incentive rates are at or above 1% for each 1% of attainment with no cap on incentive compensation.
For non-quota-based sales performance elements such as strategic sales objectives, Cisco may pay 0% up to 125% of target. Cisco sales plans do not have a minimum threshold of performance for sales incentive compensation to be paid.
