Front-End Software Engineer

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.

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.

• 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 Web Sockets 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.

• 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.
• Experience building and deploying production‑grade, data‑intensive web applications.

• Strong experience with React, Type Script, and modern front-end state management.
• Experience with data visualization libraries such as D3.js, WebGL, Three.js, or Mapbox/Deck.gl.
• Experience handling real‑time streaming data and high‑frequency updates on the frontend.
• Proficiency with design tools (Figma) and a strong eye for functional UI/UX design.
• Understanding of frontend performance profiling and optimization techniques.
• Experience with version control, CI/CD workflows, and containerization (Docker).
• Experience integrating with hardware, robotics, aerospace, defense, or IoT systems is a plus.
• Familiarity with backend services (Python, Go, or Node.js) to help define efficient data schemas.

• On‑site with the team at our office in El Segundo, CA
• Occasional travel to test sites or operator locations as needed

We are open to a wide range of experience levels. The expected salary…
