Senior C++ Software Engineer

Senior C++ Software Engineer 

Location: Hybrid or Office-Based – Philadelphia, PA. Remote candidates may be considered.

Position Summary 

We are seeking a Senior C++ Software Engineer to join Bentley’s Platform organization, contributing to the evolution of both local and cloud-based workflows that underpin Bentley’s product ecosystem. You will play a key role in enhancing the performance, scalability, and reliability of data creation, editing, and synchronization workflows across desktop applications, iTwin‑native solutions, Cesium and cloud services. Your work will play a key part in advancing Bentley’s broader vision for seamless interoperability and connected digital twins across Bentely’s product portfolio. 

Responsibilities

• Build high‑performance C++ components and maintain well‑structured, versioned libraries with clear APIs and documentation. 
• Ensure the correctness, determinism, and performance of SQLite‑backed iModels across local and CloudSQLite workflows. 
• Profile and optimize CPU, memory, I/O, and multithreading behavior to deliver measurable performance gains. Contribute to low‑level storage engine internals—file formats, indexing, transactions, queries—and surface them through clean APIs. 
• Debug and validate software across virtualized and containerized environments. 
• Enhance observability with metrics, tracing, and structured logs; define and monitor SLIs in CI/CD. 
• Expand automated testing and benchmarking; enforce performance gates and API compatibility. 
• Consistently deliver high‑quality features, lead designs for medium‑sized efforts, and improve shared infrastructure across teams. 
• Work in a collaborative team environment using GitHub for development, reviews, and CI management. 
• Partner with platform, security, and product teams through design reviews and architectural discussions.
• This role does not require travel. 
• Requires sitting or standing at will while performing work on a computer (or any other physical requirements).  

Qualifications

• Bachelor’s or Master’s in Computer Science, Engineering, or equivalent experience. 
• Strong proficiency in modern C++ (C++17/20) and experience shipping production‑grade systems. 
• Demonstrated skill in optimizing performance‑critical code paths (CPU, memory, I/O, synchronization). 
• Solid understanding of concurrency, multithreading, and diagnosing race conditions or deadlocks. 
• Experience building shared libraries, SDKs, or platform components with stable, well‑designed APIs. 
• Strong testing discipline, including unit, integration, and performance tests with automated benchmarks. 
• Experience working with backend services, APIs, and data workflows across local and cloud environments. 
• Familiarity with observability methods (metrics, tracing, structured logs). 
• Strong problem‑solving, technical ownership, and effective cross‑team communication skills. 

Preferred Qualifications 

• Experience with distributed systems concepts (retries, idempotency, backpressure). 
• Knowledge of SQL/SQLite‑like storage engines, indexing, and transactional behavior. 
• Familiarity with sanitizers, fuzzing, and stress testing. 
• Cross‑platform development experience (Windows/Linux; MSVC/Clang/GCC). 
• Experience with Docker or VM‑based development environments. 
• Understanding of API versioning, compatibility, and deprecation best practices. 
• Practical TypeScript/JavaScript experience
