Job Description:

We’re seeking a Systems Software Engineer to design, implement, and debug core platform components and the pipelines that build and update system images. You’ll work across operating system layers, focusing on performance, security, and deep system debugging to ship production‑grade systems.

Job Responsibility:

  • Design, implement, and debug system‑level components and services across kernel and user space
  • Configure and maintain OS platform services (init, services, networking, security policies) and related tooling
  • Build and operate image and update pipelines, ensuring reliability, reproducibility, and rollback safety
  • Instrument and analyze performance using profiling and tracing
  • optimize CPU, memory, I/O, and power usage
  • Own platform observability and reliability: logging, crash capture, watchdogs, and diagnostics
  • Collaborate with cross‑functional teams to define interfaces and deliver end‑to‑end features
  • Establish strong engineering practices: code review, CI, reproducible builds, and release management
  • Partner with external suppliers to support builds and deployments.

Requirements:

  • Have shipped production systems software on modern operating systems
  • Are proficient in C/C++ and a scripting language, and comfortable with OS internals (concurrency, memory management, filesystems, networking, power management)
  • Bring strong systems debugging skills using debuggers, tracers, profilers, and logs across kernel/user‑space boundaries
  • Understand configuration of platform services and interfaces, and can translate requirements into stable, well‑documented APIs
  • Are fluent in user‑space foundations (service management, IPC, networking, packaging, automation)
  • Have experience building platform images and designing update mechanisms for reliability and security.

Nice to have:

  • Exposure to platform security (secure boot, sandboxing, mandatory access controls, attestation)
  • Experience with graphics/media, hardware acceleration, or high‑throughput data paths
  • Familiarity with connectivity stacks and network configuration
  • Observability and diagnostics in distributed or resource‑constrained environments
  • Work on open‑source platforms or contributions to systems projects.
What we offer:
  • Medical, dental, and vision insurance for you and your family, with employer contributions to Health Savings Accounts
  • Pre-tax accounts for Health FSA, Dependent Care FSA, and commuter expenses (parking and transit)
  • 401(k) retirement plan with employer match
  • Paid parental leave (up to 24 weeks for birth parents and 20 weeks for non-birthing parents), plus paid medical and caregiver leave (up to 8 weeks)
  • Paid time off: flexible PTO for exempt employees and up to 15 days annually for non-exempt employees
  • 13+ paid company holidays, and multiple paid coordinated company office closures throughout the year for focus and recharge, plus paid sick or safe time (1 hour per 30 hours worked, or more, as required by applicable state or local law)
  • Mental health and wellness support
  • Employer-paid basic life and disability coverage
  • Annual learning and development stipend to fuel your professional growth
  • Daily meals in our offices, and meal delivery credits as eligible
  • Relocation support for eligible employees
  • Additional taxable fringe benefits, such as charitable donation matching and wellness stipends, may also be provided
  • Offers Equity
  • Performance-related bonus(es) for eligible employees.
