What is a Software Engineer at Ocean Power Technologies?

As a Software Engineer at Ocean Power Technologies (OPT), you are at the cutting edge of maritime autonomy. You will be responsible for developing and maintaining the software systems that power PowerBuoy® platforms and WAM-V® unmanned surface vehicles. Your work directly enables safer, cleaner, and more productive ocean operations for defense, energy, and research sectors.

This role is uniquely challenging because it requires you to operate at the intersection of high-level software architecture and physical hardware. You will bridge the gap between embedded Linux firmware and complex graphical user interfaces, all while managing real-time sensor data in unpredictable ocean environments. Success in this role means your code will be instrumental in vehicle autonomy, sensor fusion, and mission-critical communications.

Getting Ready for Your Interviews

Preparation at Ocean Power Technologies requires a balance of technical rigor and a practical mindset. You must be able to explain not just how you write code, but how that code behaves when subjected to the constraints of physical hardware in the field.

Technical Proficiency – You will be evaluated on your mastery of C++ and your ability to work across the stack. Focus on demonstrating your experience with build systems, debugging tools, and network protocols like RTSP or SRT.

System-Level Thinking – Interviewers look for engineers who understand how software interacts with mechanical and electrical systems. Be ready to discuss how your code handles hardware failure, sensor noise, or environmental volatility.

Problem-Solving under Pressure – Because your work impacts real-world autonomous missions, you must demonstrate a calm, methodical approach to troubleshooting. Highlight instances where you identified the root cause of a complex system failure.

Collaborative Communication – Since you will work across different office locations and engineering disciplines, you must show you can translate complex technical requirements to non-software stakeholders.

Interview Process Overview

The interview process at Ocean Power Technologies is structured to be rigorous and comprehensive. You should expect a series of interactions that test both your specific domain expertise and your cultural alignment with their high-stakes mission. The process typically involves multiple rounds, ranging from initial phone screens to in-person meetings with technical leads, the hiring manager, and occasionally executive leadership.

The environment is fast-paced and mission-oriented. Because Ocean Power Technologies operates in sectors like defense and offshore wind, the interviewers will look for evidence that you can handle the responsibility of deploying software to hardware that is difficult or impossible to reach for manual resets once deployed.

Key Responsibilities

As a Software Engineer, you are the architect of the digital intelligence that controls OPT's maritime assets. Your primary responsibility is the development of software components for the Merrows™ platform and the WAM-V® autonomy suite. This involves everything from low-level driver integration to high-level GUI development for situational awareness.

You will work closely with electrical and mechanical engineers to ensure that sensor inputs—such as cameras, sonar, and GPS—are seamlessly integrated into the autonomy stack. Beyond writing code, you will be responsible for creating simulation tools that allow the team to validate behavior before deployment. You may also be expected to participate in sea trials, where your software meets the reality of the ocean, requiring you to debug and troubleshoot in real-time.

Role Requirements & Qualifications

To be a competitive candidate for this position, you must demonstrate a mix of deep technical skill and practical, hands-on experience.

  • Must-have skills:

    • US citizenship.
    • At least 2 years of professional software engineering experience.
    • Proficiency in C++ for both embedded Linux and Windows GUI environments.
    • Experience with networking protocols (UDP, TCP, RTSP).
    • Familiarity with version control (Git) and build systems (CMake).
  • Nice-to-have skills:

    • Experience with computer vision or sensor fusion.
    • Knowledge of NVIDIA-based AI tools (CUDA, DeepStream).
    • Background in robotics or autonomous navigation.
    • Eligibility for a U.S. government security clearance.

Frequently Asked Questions

Q: How difficult is the interview process at Ocean Power Technologies? A: Candidates often describe the process as challenging because it focuses on practical application rather than just theoretical knowledge. Be prepared to explain how you have solved real-world problems in your previous roles.
