Preparing for this interview
884 open mechanical roles are hiring right now across 93 companies, mostly in Bengaluru — so the questions repeat. Practise them before you sit with STR.
Questions you are likely to be asked
- Why do you want to join STR?
- How would you design an API for a feature you have worked on?
- What do you do when a production issue happens on your code?
- Walk me through a system you built. How was it designed, and what would you change now?
- Tell me about a hard bug you tracked down. How did you find the cause?
Prep Sarthi gives you a free mock interview: an AI interviewer asks you questions like these out loud, from your own CV and this job, and shows your score and your weakest answer.

The Sensors Division at STR excels at applied research and advanced technology development of impactful sensor system technology to address warfighter and intelligence needs. Our contributions are the culmination of modeling, development, integration, and test and evaluation of new capabilities, with validation testing at each step of development.
The Ocean Technology and Acoustic Systems (OTAS) Group within the Sensors Division executes a broad portfolio of undersea technologies to impact sensing capabilities in contested areas. The Group develops signature exploitations, implements advanced algorithms and processing, and creates new sensing and payload technologies for critical undersea missions. The technologies can be stand-alone or for platforms such as AUVs.
STR is seeking a Mechanical Engineer with experience in the design, fabrication, integration, and testing of subsystems or payloads for unmanned platforms with emphasis on undersea sensors, payloads and vehicles. You will work with teams to realize challenging undersea applications requiring novel and complex engineering solutions. These solutions can only be accomplished by working across multidisciplinary teams to implement and demonstrate them in specific warfighter and intelligence applications.
What you will do:
- Develop technical solutions for mechanical deployable payloads and vehicles, taking into account their complex interactions with harsh maritime environments. This work requires teamwork in key areas of design and simulation, fabrication, and validation testing of mechanical payloads and systems in underwater environments
- Collaborate in all stages of undersea systems testing, including developing comprehensive test plans, building test infrastructure, and supporting teams both in the laboratory and at-sea to mature key technology and prototypes
- Provide regular communication with internal leadership and teammates while providing key input to reports and presentations for customer reviews and engagement
Who you are:
- Ability to obtain and maintain a Top Secret security clearance, for which U.S. citizenship is needed by the U.S. Government
- BS with 2+ years relevant experience or a MS in Mechanical Engineering, Ocean Engineering, Physics, or related fields
- Demonstrated background in the design, modeling, fabrication, integration, and validation of mechanical systems in support of first-concept undersea sensor payloads and vehicles
- Familiarity with computer-aided CAD/CAM design tools such as COMSOL, ANSYS, SolidWorks and tools to design components and systems
- Proficiency in thermal modeling, finite element analysis, computational fluid dynamics, or other multi-physics modeling and simulation required to quantify system performance in its operational environment
- Experience combining multiple external vendors and fabricators with in-house fabrication and integration resources to arrive at complete systems that meet functional objectives
- Experience with materials and designs to survive harsh conditions including temperature and overpressure Ability to design and implement testing methods and apparatus to quantify mechanical functionality, performance, and readiness against metrics
- Adherence to best practices for development and testing using system engineering processes that allow for continuous risk-reduction and evolution of functionality
- Ability to prepare and deliver briefings to customers, program managers, and senior management with messages appropriately tailored to the audience and purpose
Even Better:
- Strong background in working with teams to field ocean-going unmanned systems and payloads.
