Senior​/Software Engineer - C++

Siren Opt helps manufacturers make better, safer, and more reliable micro- and nano-materials. These materials are the building blocks of critical sectors of the global economy such as batteries, computer chips, aircraft components, and power systems. But, surging material demand and growing complexity are pushing production to unprecedented scales and speeds, leaving manufacturers effectively flying blind. Small, undetected variations during production lead to wastage, lower performance, higher costs, and safety risks.

Siren Opt is changing this by developing a manufacturing intelligence platform that non-destructively probes materials during production, revealing critical internal information without damaging them. Using a novel combination of cold atmospheric plasma, physics-informed machine learning, and predictive analytics, Siren Opt generates unique, real-time material fingerprints that capture material signals not accessible through conventional measurement techniques. These insights give manufacturers unprecedented visibility into how materials behave as they are made.

We turn hidden data into actionable intelligence to help manufacturers reduce variability and thus increase yield and performance. The technology can be deployed as a standalone tool or integrated directly into factory production lines. Siren Opt is currently deploying early versions of its platform with some of the largest industrial manufacturers in the world across North America, Europe, and Asia.

Siren Opt is seeking a Senior / Staff Software Engineer to design and build the high-performance C++ and systems software that powers our manufacturing intelligence platform. In this role, you will help ensure the reliability, performance, and scalability of Siren Opt's software as it runs on real customer production lines, while contributing to the architecture and technical foundations needed for a growing commercial product.

Working closely with firmware, hardware, and application engineering teams across every phase of product development, you will design and optimize multi-threaded, asynchronous software on Linux, analyze and improve performance across CPU, memory, storage, networking, and I/O, and debug complex issues that span software and hardware boundaries. You will also read, maintain, and extend existing Python tooling used for automation, testing, and data analysis, and take ownership of software components throughout the full product development lifecycle.

This position is well suited for a self-driven engineer who takes ownership of their work, writes clean and maintainable modern C++ (C++17/20), and enjoys understanding how software interacts with operating systems and hardware to achieve exceptional performance. You will contribute at a high level in a collaborative, fast-moving engineering environment, participating in architecture, technical design, and code reviews as you help ship robust software for commercial products.
