About The Position

We are seeking a Software Engineer to develop high-performance, hardware-adjacent software for advanced fabrication and optical instrumentation platforms. This is a primarily on-site role, focused on Linux-based systems development, high-throughput data handling, and software that interfaces directly with custom electronics, FPGA-backed subsystems, and precision instrumentation. An initial major project involves building a synchronized, high-bandwidth pattern streaming and data acquisition subsystem for a next-generation tool. What you'll be doing Systems & Hardware Integration: Design Linux system software to interface with FPGA-backed PCIe hardware, storage arrays, and laboratory instrumentation (DAQ, optical triggers and sync signals). Data Engineering: Develop high-throughput data pipelines, including efficient buffer management, memory handling, and real-time performance monitoring for sustained data streaming. Interdisciplinary Collaboration: Collaborate with FPGA, electrical, and optical teams to define hardware/software boundaries and lead full-system bring-up and debugging. Internal & User-Facing Tooling: Build custom lightweight monitoring, control and visualization tools for both internal and external use. Engineering Best Practice: Maintain engineering excellence through regular code reviews, GitHub workflows, clear documentation, and rigorous system testing.

Requirements

3 - 6 years in systems software, hardware-adjacent, or embedded/Linux development (equivalent graduate work or applied research work considered).
Proficiency in C++ and Python, with strong Linux fundamentals (including concurrency, memory management, and low-level I/O).
Experience building software for PCIe devices, DAQs, or custom boards, preferably in a hands-on lab setting during hardware bring-up and system debugging.
Deep knowledge of high-throughput or streaming architectures, including multi-threading, buffer management, and data integrity.

Nice To Haves

Familiarity with FPGA-integrated systems, hardware triggers, and synchronization.
Ability to read or modify Verilog/VHDL, or work closely with FPGA developers.
Experience with performance sensitive data movement.
Familiarity with server-class hardware, RAID storage, or custom compute platforms.
Background in any of the following domains is a plus; lithography/nanofabrication, DAQ systems, cameras, motion control, optical instrumentation, or high-speed measurement systems.
