About Oceanus Oceanus Marine Technologies is building the operating platform for the modern maritime world. Global trade runs on ships, and we’re redefining what’s possible at sea by leveraging modern technology. We’re a small, hands-on team based in El Segundo building full-stack systems that perform in real operating conditions across vessels, ports, and fleets. We focus on practical, deployable technology that brings safety oversight, automation, and coordination to complex maritime environments. Our founding team previously built and operated SpaceX’s Autonomous Spaceport Droneships, which are among the most advanced autonomous maritime systems ever deployed. Today, we work with leading U.S. operators to bring that same rigor and systems thinking to the next generation of maritime infrastructure. About the Role We're looking for a Front-End Software Engineer to help build the interfaces powering intelligent, connected maritime operations. You will work hands-on to design and implement operator-facing web applications that visualize live vessel telemetry, sensor data, and mission-critical alerts across edge and cloud systems. In this role, you will be responsible for turning complex maritime data into intuitive, high-performance dashboards that provide vessel operators with real-time situational awareness. You’ll thrive if you enjoy the challenge of high-density data visualization, low-latency state management, and building dependable production systems that perform in high-stakes operational environments. Our team is rethinking how the maritime world operates. Come help us build the visual backbone for safer, smarter global shipping. Key Responsibilities Architect and build production front-end applications for real-time monitoring and control of maritime assets. Design scalable client-side data architectures for live telemetry, historical time-series data, alarms, geospatial information, and equipment state. Implement low-latency data pipelines on the frontend to handle streaming vessel telemetry via WebSockets or similar protocols. Bridge design and implementation by creating reusable UI components and design patterns that ensure consistency across the platform. Collaborate with operators to understand field requirements, iterating on UI layouts to reduce cognitive load and improve operational efficiency. Support deployments and testing in live operational environments, refining interfaces based on direct operator feedback. Your Background Bachelor’s degree in computer science, engineering, or related technical discipline; OR 2+ years of professional software engineering experience in lieu of a degree. 2+ years of experience in front-end or UI/UX-focused software development.
