Sr Staff Engineer

About the role

The Sr Staff Engineer – Data Path is a senior individual contributor responsible for designing, developing, and optimizing performance-critical data path components within a distributed storage and data services platform. This role focuses on the efficient movement of data through complex software systems, with an emphasis on scalability, reliability, and low-latency performance. As a technical leader within the Infinia Engineering group, this engineer operates with broad architectural influence, partners closely with cross-functional teams, and drives best practices across the data path stack while remaining hands-on in design and implementation.

Responsibilities

• Data Path Architecture & Development
  • Design, implement, and optimize core data path components in large-scale, distributed systems.
  • Contribute to system architecture decisions affecting performance, throughput, latency, and resource utilization.
  • Develop high-quality, maintainable code for performance-critical paths, primarily in systems-level languages (e.g., C/C++).
• Performance & Scalability
  • Analyze and optimize data movement across CPU, memory, storage, and network layers.
  • Identify performance bottlenecks and drive solutions through profiling, benchmarking, and tuning.
  • Establish performance baselines and contribute to regression detection and prevention strategies.
• Technical Leadership
  • Act as a technical authority within the data path domain, influencing designs across teams.
  • Lead design reviews and provide guidance on complex technical challenges.
  • Mentor senior and mid-level engineers on systems design, performance engineering, and best practices.
• Cross-Functional Collaboration
  • Work closely with adjacent engineering teams, including platform, infrastructure, and quality engineering.
  • Partner with Product Management to ensure technical feasibility and performance considerations are reflected in roadmap planning.
  • Support downstream teams (e.g., solutions, customer engineering) as a subject matter expert when needed.
• Quality & Operational Excellence
  • Promote best practices in code quality, testing, observability, and documentation.
  • Participate in incident analysis and resolution related to data path behavior in production environments.
  • Contribute to long-term technical strategy and continuous improvement initiatives.

Qualifications

• Bachelor’s degree in Computer Science, Engineering, or a related technical field (or equivalent experience).
• 12+ years of experience in systems software, distributed systems, or infrastructure engineering.
• Strong experience designing and implementing performance-critical software components.
• Proficiency in C/C++ or similar systems programming languages.
• Solid understanding of operating systems fundamentals, concurrency, memory management, and networking concepts.
• Proven ability to work independently on complex technical problems and influence system-level outcomes.
