Software Engineer - Fullstack

About Oceanus

Oceanus Maritime 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 versatile Full Stack Software Engineer to help build the core platform powering intelligent, connected maritime operations. You will work hands-on across backend services, real-time data pipelines, and operator-facing web applications that integrate live vessel sensor data across edge and cloud systems.

In this role, you’ll help design and deploy resilient software that performs reliably in challenging real-world environments. You’ll thrive if you enjoy owning systems end-to-end, moving between architecture and implementation, and turning ambitious operational concepts into dependable production systems.

Our team is rethinking how the maritime world operates — come help us build the backbone for safer, smarter global shipping.

Key Responsibilities

Design and build backend services and APIs to ingest, process, and distribute real-time maritime data

Develop intuitive, mission-critical web applications for vessel operators and fleet managers

Architect scalable systems spanning edge and cloud environments

Implement event-driven and streaming data pipelines for live vessel telemetry

Aggregate multi-system signals to perform real-time risk analysis and surface recommended operator actions

Prototype new system designs and evaluate technical trade-offs

Own testing, deployment, monitoring, and reliability of production systems

Support deployments and testing in live operational environments, iterating based on field and operator feedback

Basic Qualifications

Bachelor’s degree in computer science, engineering, mathematics, or related technical discipline; OR 2+ years of professional software engineering experience in lieu of a degree

2+ years of experience in full stack development

Experience building and deploying production-grade applications

Preferred Skills and Experience

Strong programming experience in Python, Go, C#, JavaScript, or similar languages

Experience building single-page web applications (React, Angular, or similar frameworks)

Experience designing scalable software systems and distributed architectures

Experience with real-time data pipelines, event-driven architectures, or messaging systems (MQTT, Kafka, NATS, RabbitMQ, or similar)

Experience with version control and CI/CD workflows

Production experience with Docker and Kubernetes

Database experience with PostgreSQL, SQL Server, or similar relational databases

Experience deploying and operating software across edge and cloud environments

Strong understanding of testing, continuous integration, build systems, deployment, and production monitoring

Experience integrating with hardware, edge devices, robotics, aerospace, defense, or IoT systems is a plus

Work Environment

On-site with the team at our office in El Segundo, CA

Occasional travel to test sites or operator locations as needed

Compensation and Benefits

We are open to a wide range of experience levels. The expected salary range for this role is $130,000 - $220,000. Final compensation will be determined based on experience, skills, and scope of the role.

We offer a comprehensive benefits package that includes:

Comprehensive Medical, dental, and vision coverage

Generous Equity participation

Flex Paid time off and company holidays

401(k) traditional and roth options

Additional benefits that support your health, growth, and well-being

Why Now — Why Oceanus

Maritime operations are at the edge of a revolution — new connectivity and compute are finally unlocking remote monitoring, autonomy, and digitization.

Regulatory, economic, and geopolitical pressure is accelerating technology adoption, and U.S.-aligned infrastructure is more valuable than ever.

Oceanus is not just another vendor — we are building on hard-won operational experience, including work on autonomous maritime systems supporting missions like SpaceX droneships, and have deep operator engagement with strong product-market alignment.

You will help form the technical core of a team transforming an industry that quite literally moves the world.
