To excel in the technical rounds, you must understand the specific domains Oceaneering engineers evaluate. Expect your interviewers to drill down into these core areas.

Embedded Systems & Real-Time Operating Systems (RTOS)

If you are interviewing for roles involving flight software, robotics, or control systems, you must show that you understand how software interacts directly with hardware.

Be ready to go over:

• Memory management – Understanding stack vs. heap, avoiding memory leaks, and managing dynamic memory in embedded C/C++.
• Interrupt handling – How interrupts work, writing interrupt service routines (ISRs), and managing race conditions.
• RTOS primitives – Confidently explaining tasks, semaphores, mutexes, queues, and priority inversion.
• Advanced concepts (less common) – Low-level hardware protocols (I2C, SPI, CAN bus) and Core Flight System (cFS) architecture.

Example scenarios:

• "Describe how you would design a multi-threaded system to read sensor data at 100Hz while simultaneously transmitting telemetry at 10Hz without missing deadlines."
• "How would you diagnose a suspected memory leak on an embedded system that has no debugger attached?"

Safety, Reliability, and Fault Tolerant Design

Oceaneering builds systems for harsh environments. Your interviewers want to see that you design software with failure in mind.

Be ready to go over:

• Fault detection and isolation – Techniques for identifying when a subsystem is behaving abnormally.
• Redundancy management – How to coordinate primary and backup software systems.
• Defensive programming – Writing code that gracefully handles unexpected inputs or states.
• Advanced concepts (less common) – Implementing watchdog timers, heartbeats, and designing software to meet specific NASA safety standards.

Example scenarios:

• "Walk us through how you would design a software-based safety interlock for a robotic arm to prevent it from colliding with a structural barrier."
• "If a critical configuration file is corrupted on boot, what fallback strategy should the software execute?"

System Architecture & Diagram-Based Problem Solving

A unique aspect of Oceaneering interviews is the use of visual aids. You may be shown a diagram of a physical system or a software architecture and asked to analyze it.

Be ready to go over:

• Data flow analysis – Tracing how data moves from a physical sensor through software layers to an operator interface.
• System boundary identification – Defining where the software's responsibility ends and the hardware's begins.
• Failure point identification – Pointing out single points of failure in a system diagram.

Example scenarios:

• "Here is a diagram of a dual-redundant thruster control system. Walk us through how the software determines which thruster is healthy and when to command a failover."
• "Looking at this block diagram, where would you implement data logging to ensure we can reconstruct system state after an anomaly?"

As a Software Engineer at Oceaneering, your day-to-day responsibilities will be highly dynamic and deeply integrated with the physical systems you support.

You will spend a significant portion of your time designing, implementing, and testing software modules. This involves writing clean, maintainable C/C++ or Python code, developing automated test suites, and performing hardware-in-the-loop (HIL) testing to verify software performance on physical rigs.

Collaboration is a core part of the job. You will work in Integrated Product Teams (IPTs) alongside systems engineers, safety experts, and project managers. You will actively participate in software design reviews, hazard analyses, and flight or mission readiness reviews, ensuring your software meets all safety, quality, and performance requirements.

Additionally, you will be responsible for identifying and mitigating risks. This includes performing software safety assessments, analyzing telemetry data to troubleshoot anomalies, and drafting technical documentation to support system certification.
