Job description

Senior Front End Software Engineer

Build and maintain the front-end command center UI for Seasats' autonomous surface vessels.

Location: San Diego, California, United States

Compensation: $160 - 210 USD / hour

Job Tags: Software

About The Role

The vehicle user interface team is responsible for building the command center for our ASVs – the essential tool operators use to monitor and control every mission. Our operators and our customers rely on the vehicle interface to present complex vessel data clearly and intuitively, whether they're navigating through crowded harbors or operating with limited communication hundreds of miles offshore. As part of the team, you'll build a deep understanding of our ASVs' capabilities, the vision behind them, and the realities that operators experience when using them. Armed with this knowledge, you’ll work to design and implement an interface that presents complex vessel data clearly and intuitively, and also feels natural to experienced operators and first‑time operators alike. You’ll collaborate closely with roboticists, test engineers, and field operators to ensure what you build works in both theory and practice.

On a day‑to‑day basis, you will:

• Build and maintain high‑performance code in JavaScript/React to command and monitor our fleet.
• Spend time mentoring teammates and collaborating to shape the team’s technical path.
• Connect with operators and make the occasional trip to the local launch points to deepen your understanding of issues and use cases.
• Collaborate with the team to implement or refine features based on real‑world feedback.
• Improve and extend testing, deployment, and monitoring infrastructure.
• See your code come to life every time a boat goes on the water.

This is an excellent opportunity to do high impact work, see your code go into live field robotics applications, and join a fun and hard‑working team on the cutting edge of ocean autonomy.

About You:

• 5+ years of experience developing SPAs/PWAs with modern frameworks (e.g. React, WebComponents, Vue).
• Strong UI/UX design principles and tools experience.
• Proven experience iterating on released projects used actively by customers in the field.
• A command of software engineering principles – including testing, deployment, and performance tuning.
• Proficiency working with databases (MySQL, PostgreSQL, time‑series databases).
• Excellent leadership, collaboration, and teamwork skills.
• Ability to obtain a security clearance (U.S. Citizenship may be required).

Nice (though not essential) if you have:

• Experience with real‑time data, control systems, or physical robotics platforms.
• Background in maritime systems or mission control environments.
• Familiarity with mapping APIs (e.g., Leaflet, Cesium, etc.).
• Experience with data visualization or telemetry dashboards.

At Seasats, we're passionate about delivering maritime robotics solutions to redefine the maritime industry. Our primary products are autonomous surface vehicles (ASVs), designed to carry sensors at sea for months at a time. Our ASVs provide persistent monitoring and data acquisition to defense, scientific, and commercial customers, and have autonomously crossed both the Pacific and Atlantic oceans. After thousands of years in which the only way to gather information from the ocean was to put people on a boat, these uncrewed vessels are transforming how humanity monitors and interacts with the ocean. Here, you'll find the space and opportunity to do your life's best work.

Perks

• Stock options
• Competitive insurance (including a 99% employer‑covered Gold HMO plan or other options)
• 401k matching up to 4% of salary
• Four free lunches per week
• An employee activity fund
• A pet‑friendly office
• Unlimited/Flex PTO
