System Engineer

👥 Platform 📍 Remote (Worldwide) 💼 Full-time 🏆 Mid-Senior (4-8 years) 💰 $130,000 – $170,000 USD
Linux Networking Distributed Systems Performance Security C/C++

About the Role

We're looking for a System Engineer to work on the low-level infrastructure and systems that underpin Lit8's platform. You'll tackle performance bottlenecks, harden our security posture, and design reliable systems that scale — working at the layer between our application code and the hardware it runs on.

This is a role for someone who enjoys understanding how things work at a fundamental level and takes pride in building systems that are fast, secure, and resilient.

What You'll Do

  • Design and optimize core system infrastructure for performance and reliability
  • Investigate and resolve complex performance issues across the stack
  • Improve system security through hardening, auditing, and best practices
  • Build and maintain monitoring, alerting, and capacity planning systems
  • Design networking architectures, load balancing strategies, and failover mechanisms
  • Automate system provisioning, configuration, and maintenance
  • Collaborate with application engineers to optimize resource usage and system behavior
  • Document system architectures, runbooks, and operational procedures

What We're Looking For

  • 4-8 years of experience in systems engineering, SRE, or low-level infrastructure work
  • Deep understanding of Linux internals (kernel, networking, filesystems, processes)
  • Strong networking fundamentals (TCP/IP, DNS, TLS, load balancing)
  • Experience with performance analysis and profiling tools
  • Proficiency in at least two of: C, C++, Go, Python, Rust
  • Solid understanding of distributed systems concepts (consensus, replication, partitioning)
  • Comfort with debugging complex issues across multiple system layers

Nice to Have

  • Experience with kernel tuning or custom kernel module development
  • Background in storage systems or database internals
  • Familiarity with eBPF or system tracing tools (perf, bpftrace, strace)
  • Security certifications or experience with compliance frameworks
  • Contributions to infrastructure open-source projects
