Join Pendar to become part of a place that's developing cutting-edge technology and is making a significant impact safeguarding our country and communities.

About the Role

Pendar Technologies is seeking a R&D Engineer to support the development, testing, and improvement of advanced optical sensing systems. This role is highly hands-on and spans research, product development, and manufacturing support. You will work across multiple domains including materials (e.g., surface cleaning, adhesives), system reliability, automation, and environmental testing.

This is an ideal role for an engineer who enjoys building, experimenting, and solving real-world hardware problems in a fast-paced, collaborative environment.

Primary Responsibilities

• Support the design, execution, and analysis of engineering experiments under the guidance of senior R&D team members. Areas of focus include surface cleaning and preparation, adhesive selection, material characterization, optical and thermal curing processes, assembly manufacturability and repeatability, and statistical analysis of manufacturing process data.
• Build and evaluate physical prototypes to validate new design concepts and assess assembly methods, precision optomechanical alignment procedures, and manufacturing processes.
• Assist in the development and implementation of environmental and reliability testing methods based on standards such as MIL-STD-810, including temperature cycling, thermal shock, humidity exposure, mechanical shock and vibration, electromagnetic susceptibility, and altitude testing.
• Collect, analyze, and present performance and reliability data generated from prototypes and test systems operating under a variety of environmental and stress conditions.
• Investigate product and process failures, perform root cause analysis, and support corrective action implementation.
• Design, build, improve, and maintain engineering test equipment, manufacturing fixtures, and experimental setups.
• Take a leading role in early-stage product testing, performance evaluation, and quality assessment activities.
• Collaborate closely with manufacturing, quality, and engineering teams to identify, troubleshoot, and resolve product and process issues.

Qualifications

• B.S. in Mechanical Engineering, Applied Physics, Electrical Engineering, or related Engineering field
• 1–3 years of experience (internships or research experience included)
• Strong hands-on skills in mechanical assembly, soldering, PCB prototyping, familiarity with machine shop tools and 3D printing.
• Strong communication and documentation skills are required for recording and sharing SOPs and test results with other engineers

Nice to Have

• Familiarity with data analysis software tools (Python, MATLAB, MINITAB, etc.)
• Exposure to standard manufacturing engineering practices.

Location and Additional Information

• This is a full-time position, fully on-site in Cambridge, MA, accessible by car, bike, and bus
• Salary range of $80,000 to $100,000 depending on the candidate
• Competitive benefits include healthcare, dental, vision, and matching 401k
