Full Stack Software Engineer

Location: Lexington, MA

Department: Engineering

The Role

We are seeking a Full Stack Engineer to design, build, and operate software systems that span from low-level sensor data and autonomy infrastructure to operator-facing web applications. This role is centered on Go-based backend systems and server-side rendered web applications, integrating closely with ROS 2–based autonomy software and real-world maritime platforms. Engineers in this role take ownership end-to-end and work hands-on in the field as part of small, high-performing teams.

U.S. Person status is required as this position needs to access export controlled data.

What You'll Do

• Design, implement, and maintain full stack software systems supporting autonomous maritime platforms, from ROS 2 nodes and sensor data pipelines to backend services and server-rendered web interfaces.
• Build and maintain backend services written primarily in Go
• Develop server-side rendered web applications using Go, HTML, and HTMX, enabling fast, reliable operator and internal tools without unnecessary frontend complexity.
• Work directly with ROS 2–based autonomy systems, integrating sensor data, control interfaces, and system health signals.
• Design and maintain PostgreSQL-backed data models and services supporting autonomy, operations, simulation, and fleet analysis.
• Collaborate closely with autonomy, robotics, electrical, and mechanical engineers to integrate software with hardware and vehicle systems.
• Remotely support field deployments, vessel integration, testing, and troubleshooting in real-world maritime environments, occasionally traveling for in-person support.
• Own software components end-to-end, from initial design through deployment, validation, and long-term operation.
• Contribute to engineering standards, tooling, and architectural decisions that improve reliability, observability, and development velocity.

Who You Are

• 3–8+ years of professional software engineering experience with demonstrated ownership of backend systems and user-facing applications.
• Strong experience building production systems in Go, with solid understanding of Go concurrency and best practices.
• Experience designing server-side rendered web applications, including HTML templating and progressive enhancement using tools such as HTMX.
• Experience working with PostgreSQL or similar relational databases.
• Experience with ROS 2 or comparable robotics or distributed middleware, including real-time or near–real-time data flows.
• Comfortable working close to hardware and real-world systems, including sensor data, autonomy software, and operational constraints.
• Willing and able to spend time in the field supporting system integration, testing, and deployment.
• Strong systems-thinking skills and the ability to debug across software layers and interfaces.
• Communicate clearly, balance speed with rigor, and take ownership from concept through delivery.
• Energized by solving practical engineering challenges in fast-moving, mission-driven environments.
• Must be a U.S. citizen and eligible to work on U.S. defense-related programs.

What We Offer

• Incredibly high-caliber teammates. You’ll work directly with our co-founders Rylan, Scott, and Austin. 
• A fast-paced, creative working environment that offers a lot of room for ownership and growth.
• Opportunity to join a meaningful mission that protects America and our Democracy.
• Expected Salary Range: $190,000-$210,000 annual base salary. Final compensation will depend on experience and skill level
• Startup equity options
• Generous PTO, medical, dental, and vision coverage

We are an equal opportunity employer. All hiring is contingent on eligibility to work in the United States. We are unable to sponsor or transfer visas for applicants.
