Job description

Eligible candidates must be local to Jersey City, NJ and W2 only!

Job Description:

  • Regularly pull upstream changes into the internal branch, pinning integrations to reviewed commits and resolving merge conflicts independently.
  • Maintain reliable builds and runtime compatibility across:
    • RHEL 9, 8, 7 and 6
    • Windows
    • macOS
  • Write compatibility shims when upstream code uses newer system calls—for example, addressing the renameat2compatibility requirement on RHEL 7.
  • Ensure every new upstream plug-in links successfully on all supported targets, including routing plug-ins to the approved, safe copy of SQLite.
  • Automate CI safety checks, including:
    • glibc version ceilings
    • Ensuring plug-ins do not link against the system libsqlite3.so
    • Detecting unresolved plug-in symbols
    • Smoke testing in Rocky Linux and CentOS containers

Essential experience:

Candidates should have:

  • At least seven years of hands-on C++ development on Linux, using GCC and/or Clang.
  • Strong experience with modern C++, preferably C++17 or C++20, with C++23 knowledge being advantageous.
  • Expert-level Git skills for managing large and complex merges, including:
    • Three-way merges
    • merge-base
    • Reuse Recorded Resolution (rerere)
    • git log A..B
    • git bisect
  • Experience maintaining a long-lived fork of a fast-moving open-source project would be highly desirable.
  • Strong knowledge of linkers and ELF binaries, including:
    • Static versus shared linking
    • Position-independent code (PIC)
    • Symbol versioning
    • readelf -V, nm -D and ldd
    • Linker version scripts
    • --export-dynamic
  • A deep understanding of glibc and RHEL compatibility—for example, why an Ubuntu 24.04 binary may fail on RHEL 9 and how to resolve the issue.
  • Experience with Meson and Ninja, plus vcpkg, including triplets and manifest mode.
  • Sufficient CMake knowledge to read and understand existing build configurations.
  • Docker experience for reproducible builds and test containers.
  • Experience producing Windows builds with MSVC and managing DLL deployment.
  • Experience implementing and maintaining GitHub Actions CI pipelines.

Desirable experience:
