Senior Backend Software Engineer C++
San Francisco Bay Area
Full-time
Hybrid
Senior Level
5+ years expVinci4D.ai combines a foundation model for physics with GPU-native solvers to deliver unprecedented simulation speed and accuracy. They are seeking a Senior Backend Software Engineer with a strong focus on C++ to implement and maintain production application code, ensuring features are performant and useful for customers.
Artificial Intelligence (AI)HardwareInformation Technology
Responsibilities
Implement and maintain production C++ application code (C++14/17/20) across parsing, simulation, and inference pipelines
Build robust file parsers and import pipelines for formats such as OAS, GDS, ECXML, STL, STEP, and other domain formats used in hardware/layout tooling
Design and implement algorithms and data structures for large datasets: streaming parsing, memory-efficient representations, and zero-copy APIs where appropriate
Improve inference and simulation performance end-to-end: profiling, algorithmic improvements, vectorization, multi-threading, and selective use of accelerators
Architect and implement distributed execution of simulation/compute workloads that can scale across many CPUs and hosts - job partitioning, scheduling, fault tolerance, and results aggregation - ensuring the work integrates cleanly with application-level APIs
Integrate native C++ components with higher-level services (Python bindings, gRPC APIs, protobufs) so features are consumable by customers and downstream systems
Own the full lifecycle of features: design, implementation, testing, CI/CD, packaging, documentation, and production rollout
Write and maintain unit/integration tests, fuzz tests, and performance benchmarks; use CI to enforce correctness and prevent regressions
Profile and debug complex issues using tools like perf, gdb, sanitizers (ASan/TSan), valgrind, and CPU/heap profilers; tune memory and CPU usage
Participate in code and design reviews; mentor junior engineers and promote engineering best practices
Collaborate with product and customer success teams to ensure features meet customer needs and are easy to consume
Qualification
Required
Minimum 5+ years professional software engineering experience, with a strong focus on C++
Strong production experience in modern C++ (C++14+) including templates, RAII, move semantics, and modern idioms
Proven experience implementing non-trivial application logic (parsers, algorithms, data structures), not just micro-optimizations
Deep understanding of Linux internals: processes, threads, scheduling, signals, memory management, and syscalls
Expertise in concurrency: threads, mutexes, atomics, memory model, condition variables, and designing safe concurrent systems
Hands-on experience with debugging and profiling tools (perf, gdb, sanitizers, profilers)
Experience working in large-scale codebases: modular design, safe refactors, cross-module interfaces, and collaborative development
Strong engineering discipline: testing, CI/CD, clear documentation, and reliable release practices
Excellent communication skills and demonstrated ownership of end-to-end features
Preferred
Familiarity with EDA/layout file formats (OAS, GDS, ECXML, etc) and domain XML schemas
Experience integrating C++ with Python (pybind11, CPython APIs) and exposing gRPC/protobuf APIs
Experience distributing compute with MPI, task queues, or custom job schedulers; knowledge of Kubernetes, Slurm, or HPC schedulers
GPU acceleration experience (CUDA/ROCm) or writing GPU-aware C++ code for inference/simulation
Experience with PostgreSQL or other relational DBs for metadata and operational tooling
Familiarity with build systems and tooling: CMake, LTO, cross-compilation, and packaging
Knowledge of binary serialization (protobuf, FlatBuffers), zero-copy techniques, and high-performance I/O (io_uring)
Frontend familiarity (React) for building or collaborating on internal UIs
Cloud and infra experience (GCP/AWS, Terraform) and operating HPC/GPU clusters
