Job Description

We’re hiring a C++ Software Engineer to build and maintain high‑quality, performant backend services and libraries that power core product features. You’ll work across the full SDLC—design, implementation, testing, performance tuning, and release—partnering with product and platform teams.

Job Responsibility

  • Design and implement robust, modern C++ (C++17/20) services, libraries, and APIs
  • Optimize for performance, memory, and reliability (profiling, benchmarking, CPU/memory analysis)
  • Build unit/integration tests and contribute to CI/CD pipelines
  • Debug complex, concurrent systems (threads, async I/O, lock‑free patterns where applicable)
  • Collaborate on system design (docs, diagrams, trade‑offs) and code reviews
  • Integrate with networking, storage, and messaging components (REST/gRPC/TCP)
  • Write clear documentation and support production releases (on‑call rotation optional)

Requirements

  • 3–7+ years professional C++ development (C++14/17/20), STL, templates
  • Strong grasp of data structures, algorithms, and concurrency
  • Experience with Linux development, build systems (CMake, Ninja), and debugging tools (gdb, valgrind, perf)
  • Familiarity with Git, code reviews, and modern engineering practices
  • Comfortable reading RFCs/docs and working from ambiguous requirements

Nice to have

  • Networking (sockets, epoll/kqueue, ZeroMQ, gRPC)
  • Performance engineering (SIMD/Intrinsics, lock‑free queues, io_uring)
  • Cross‑platform dev (Windows/MSVC), C# or Python for tooling
  • Experience with Docker, Kubernetes, or cloud (AWS/Azure)
  • Observability: Prometheus, Grafana, OpenTelemetry

What we offer

  • medical
  • vision
  • dental
  • life and disability insurance
  • 401(k) plan
