Senior Systems Engineer

About the Role We are looking for a Senior Systems Developer to lead the design, development, and operation of large-scale distributed systems powering high-performance infrastructure. This role goes beyond implementation—you will drive architectural decisions, influence system design across teams, and set the standard for building reliable, scalable, and efficient systems.

You will operate at the intersection of software and infrastructure, partnering closely with platform, networking, and hardware teams to deliver production-grade systems at significant scale.

What You’ll Do

Lead the design and development of large-scale distributed systems (1000+ nodes)

Own critical services across compute and network infrastructure, ensuring reliability and performance at scale

Drive system architecture decisions, including scalability, fault tolerance, state management, and data consistency

Partner cross-functionally to deliver end-to-end solutions from concept through production and ongoing operation

Mentor and guide engineers, raising the technical bar across the team

Diagnose and resolve complex, system-level issues spanning software, networking, and infrastructure layers

Identify and implement opportunities to improve performance, reliability, and operational efficiency through automation and tooling

Influence long-term technical strategy and roadmap for distributed systems infrastructure

Minimum Qualifications

Bachelor’s or Master’s degree in Computer Science or a related technical field (or equivalent practical experience)

8–12+ years of experience building and operating large-scale production systems

Deep understanding of operating systems, distributed systems, and computer networking

Strong proficiency in multiple programming languages (e.g., Python, Java, C/C++, Go)

Proven experience owning systems and services across the full development lifecycle

Strong technical leadership, problem-solving ability, and communication skills

Participate in an on-call rotation to support production systems

Preferred Qualifications

Deep expertise in Linux systems and performance optimization

Strong background in distributed systems architecture, including data synchronization, fault tolerance, and state management

Experience with large-scale compute, storage, and networking environments

Familiarity with server and GPU hardware architecture and system-level optimization

Experience with high-performance networking (e.g., InfiniBand, RoCE)

Hands-on experience building and operating public cloud or data plane services

Experience with databases and caching systems (e.g., MySQL, Redis, Memcached)

What We’re Looking For

A systems leader who can think at scale and drive architectural clarity in complex environments

Someone who takes ownership of critical systems and drives them end-to-end

A pragmatic engineer who balances speed, quality, and long-term maintainability

A mentor and multiplier who elevates the team around them
