Software Integration & Test Engineer

SOFTWARE INTEGRATION & TEST ENGINEERMesh Optical Technologies was founded on the belief that optical photons will be at the center of advanced technologies in the coming century. Making advanced technology ubiquitous means building at scale, and that's exactly what we're doing at Mesh.We are seeking a Software Integration & Test Engineer to own the software that automates, controls, and monitors our production lines and test infrastructure. You will build the systems that drive production equipment, orchestrate test execution, and ensure every process step is observable, traceable, and reliable at volume.RESPONSIBILITIESOwn the software that automates production lines and controls hardware interfaces between factory tools, stations, instruments, and workflowsOwn the software that automates end-of-line production test systems and development lab test environments, ensuring deterministic execution and reliable results at throughputDevelop and maintain test automation frameworks used for qualification, validation, and manufacturing, including instrument control, sequencing, and pass/fail determinationBuild and maintain data acquisition pipelines for test results, process logs, and system metrics, ensuring production data is captured, stored, and accessible for analysisImplement health monitoring, fault detection, and alerting across manufacturing and test software systemsSupport root-cause analysis for line interruptions, process excursions, test escapes, and automation failuresWork closely with process and manufacturing engineering to ensure every process parameter is fully observable, controllable, and traceable across the lineSupport CI-driven test and integration environments that validate hardware, firmware, and software changes prior to production deploymentExtend automation and control systems to support new product introductions, process changes, and production rampsInterface with mechanical, electrical, optical, and manufacturing engineering teams to resolve integration issues that span hardware and software boundariesBASIC QUALIFICATIONSBachelor's or Master's degree in computer engineering, computer science, electrical engineering, or a related discipline1+ years of hands-on software development experience (internships, co-ops, and substantive project experience qualify)Strong proficiency in Python, with experience writing production-quality codeExperience developing and operating software in Linux environmentsFamiliarity with CI systems, automated testing pipelines, and deployment workflowsDemonstrated engineering intuition, critical thinking, and comfort with ambiguityWillingness to work extended hours and weekends as neededPREFERRED SKILLS AND EXPERIENCEExperience interfacing software with manufacturing equipment, instrumentation, or controls systems (e.g., instrument control via GPIB, USB, serial, or Ethernet)Strong proficiency in C or C++ in addition to PythonStrong understanding of networking fundamentals (TCP/IP, serial protocols, device communication)Experience with data acquisition, time-series data, or production database systemsExperience designing software systems for observability, fault tolerance, and long-term maintainabilityExperience with hardware-in-the-loop testing, test automation frameworks, or automated validation systemsBackground in hardware-centric or high-volume manufacturing environmentsExperience with containerization, infrastructure-as-code, or deployment automationFamiliarity with MES systems, production traceability, or factory data infrastructureExperience with version control (Git) and collaborative software development workflowsCOMPENSATION AND BENEFITS:Pay range:Software Integration & Test Engineer: $115,000.00 - $140,000.00/per yearTitle and base salary are determined on a case by case basis commensurate with experience and merit.In addition to base salary, compensation for this role includes:Eligibility for long-term incentives including company stock options and discretionary bonuses awarded for exceptional achievements.Comprehensive medical, vision, and dental insurance with significant cost covered by the company for yourself and dependents.Paid parental leave and flexible PTO (3 weeks accrued vacation and 10 company holidays per year).401(k) retirement plan access.Relocation assistance to sunny Los Angeles.
