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.

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
