Job Details

We’re looking for a seasoned C++ engineer to join a small, highly technical team building performance-critical systems used in production at scale. This role is hands-on and impact-driven: you’ll be working close to the metal, influencing architecture decisions, and helping modernize a mature C++ codebase without breaking what already works.

If you enjoy solving hard problems, care deeply about correctness and performance, and like working with other engineers who actually read compiler output, this will feel like home.


What You’ll Do

  • Design, implement, and maintain high-performance C++ services and libraries used in mission-critical systems

  • Work on large, long-lived C++ codebases (C++14/17/20) with an emphasis on performance, reliability, and maintainability

  • Profile, debug, and optimize complex systems (memory usage, latency, threading, CPU utilization)

  • Collaborate with product, systems, and infrastructure teams to translate requirements into technical solutions

  • Review code and provide thoughtful feedback, with an eye toward long-term maintainability

  • Participate in architectural discussions and help guide technical direction

  • Mentor mid-level engineers and contribute to raising the overall engineering bar

  • Occasionally support production issues and root-cause analysis


What We’re Looking For

  • 8+ years of professional C++ development experience in production environments

  • Deep understanding of modern C++ (RAII, templates, STL, smart pointers, move semantics)

  • Strong experience with multithreading, concurrency, and synchronization primitives

  • Solid grasp of performance tuning and low-level debugging (gdb/lldb, valgrind, perf, sanitizers)

  • Experience working in Linux-based environments

  • Familiarity with build systems (CMake, Bazel, or similar)

  • Ability to reason about complex systems and make pragmatic tradeoffs

  • Comfortable owning features end-to-end in a collaborative, low-ego environment

Nice to Have

  • Experience with distributed systems or networking

  • Exposure to real-time or latency-sensitive systems

  • Some experience with Python or scripting for tooling and automation

  • Prior work modernizing legacy C++ codebases


Compensation & Benefits

  • Annual bonus: 10–15% target

  • Equity: Meaningful stock options or RSUs

  • Health coverage: Medical, dental, and vision with the majority of premiums covered

  • 401(k): Company match up to 4%

  • Time off: 20 days PTO plus paid holidays and sick time

  • Flexibility: Flexible working hours and remote-friendly culture

  • Learning budget: Annual stipend for conferences, books, or courses

  • Equipment: High-end workstation or laptop of your choice

  • Culture: Low-meeting, engineering-focused environment that values deep work
