Full Job Description
Location: Austin, TX. Full-time onsite position.
Reports To: VP, Optics
FLSA Status: Exempt
Position Overview
Neurophos seeks a Principal Optical Engineer to own active alignment for our optical processing unit (OPU). You will define how we align and bond fiber arrays, microlens arrays, collimators, metasurfaces, and photonic and detector chips to sub-micron and micro-radian tolerances. You will build the processes and stations to do so and take them from first lab prototypes to volume production with our manufacturing partners. You will work closely with the optical design, optomechanical, metrology, and manufacturing teams and serve as the company's technical authority on active alignment.
Key Responsibilities
Alignment strategy and process
Own the active-alignment strategy for free-space and fiber-coupled OPU sub-assemblies: degrees of freedom, alignment sequence, datums, and the feedback signal for each step.
Translate optical tolerance budgets into alignment requirements, capture ranges and pass/fail criteria, working with optical design and optomechanical engineering.
Develop alignment algorithms: coarse search, gradient and hill-climb optimization, multi-axis merit functions and simultaneous alignment of many channels.
Develop bonding processes: adhesive selection, bond-line control, UV and thermal cure, cure-shift prediction and pre-compensation, and post-bond stability.
Equipment and automation
Specify, build, or source active-alignment stations: hexapods and precision stages, machine vision, power- and image-based feedback, dispense and cure.
Develop and maintain alignment and station-control software, with data logging for process and yield analysis.
Qualify stations for accuracy, repeatability, cycle time and throughput.
Suppliers and production
Transfer alignment processes to contract manufacturers and component suppliers; write process specifications, work instructions and acceptance criteria.
Drive yield, cycle time and cost from prototype through low-rate initial production; lead root-cause analysis and corrective action on alignment failures.
Qualify aligned assemblies through thermal cycling, shock, vibration, and long-term stability testing.
Mentor engineers and technicians across optics, optomechanics, and manufacturing.
Qualifications
PhD or MS in Optics, Physics, Electrical or Mechanical Engineering, or a related field.

Programming skills in Python, C#, or LabVIEW for instrument control, automation, and data analysis.
Track record of transferring processes to contract manufacturers and suppliers.
Comfortable using AI tools in your day-to-day engineering work. We are building AI into how we design, align, and test optics.
Preferred Skills
Commercial active-alignment platforms and their software environments.
Design of experiments, statistical process control, and yield modeling.
Wafer-level or panel-level alignment and bonding.
