Requirements
  • Ten+ years in HR/People leadership, including experience as the senior-most HR leader at a company of 100+ employees
  • Experience partnering directly with founders or CEOs on company-wide organizational decisions
  • Experience coaching and developing new managers
  • Built or significantly evolved an HR function at a high-growth startup, including systems, compensation structures, and onboarding
  • Experience evaluating and improving existing HR systems and processes, not just building from a blank slate
  • A track record of earning trust and buy-in from executives and managers without needing constant oversight

  • Excellent judgment for navigating situations without an obvious right answer
  • Due to export control requirements, must be a U.S. person as defined by U.S. export control laws (U.S. citizens, lawful permanent residents, or individuals granted asylee or refugee status)
Responsibilities
  • Build and continuously improve the HR function: policies, programs, and practices suited to a fast-moving company (probably not a Fortune 500 playbook)

  • Evaluate and refine compensation philosophy, salary structure, benefits program, and related vendor relationships
  • Partner with the CEO and leadership on org design, workforce planning, and personnel growth plans

  • Own employee relations and other sensitive matters with sound judgment
  • Strengthen how we recruit, partnering with hiring managers to identify and attract the best talent while improving candidate experiences
  • Flag organizational risks before they become fires, and bring solutions, not just problems, to leadership
  • Help ensure Seasats remains a place where exceptional people can do the best work of their careers
Desired Qualifications
  • A strong knowledge of California employment law and experience managing compliance across multiple states

Seasats builds autonomous maritime systems for defense and scientific data-gathering missions. Its flagship Seasats X3 is an unmanned vessel that can perform dangerous naval ISR tasks without putting humans at risk. The platform operates by autonomously navigating and carrying a configurable set of sensors and electronic warfare tools; clients can lease the vessels and either bring their own sensors or choose from Seasats’ sensor library, with optional training and support. Revenue comes from leasing fees, sensor integration services, and data collection contracts. Seasats differentiates itself with low-logistics, high-efficiency maritime solutions that withstand harsh seas and are easy to transport by air or land, plus flexible pricing and sensor options. The company’s goal is to enable safe, effective autonomous ISR operations for government, research institutions, and large enterprises through adaptable platforms and support.

Simplify's Take

What believers are saying

  • Seasats won a $24 million APFIT award on January 15, 2026.
  • It closed a $20 million Series A on February 17, 2026.
  • Quickfish completed an eight-day trial in March 2026, and Heavyfish launches this fall.

What critics are saying

  • Anduril and Kraken announced small USV production partnerships in April 2026.
  • Seasats still depends on U.S. Navy and Marine Corps contracts for most demand.
  • A failed production ramp or delayed Heavyfish launch in 2026 would crush credibility.

What makes Seasats unique

  • Lightfish crossed the Pacific and Atlantic, proving sea endurance others still lack.
  • Seasats sells sub-$1 million USVs, keeping procurement easier than crewed ships or primes.
  • Quickfish and Heavyfish extend one autonomy stack across interceptor and long-range missions.

Seasats Quickfish USV completes eight-day trial, achieves multi-week endurance capability

Seasats has completed an eight-day continuous sea trial of its Quickfish unmanned surface vessel, demonstrating extended endurance capabilities for the interceptor-class platform. The high-speed USV reaches over 35 knots and is designed for multi-week on-station operations, supporting port security, border protection and coastal defence missions. The Quickfish features a payload bay for delivering unmanned aerial vehicles and combines low-speed electric propulsion with high-speed jet drive. This distinguishes it from similar vessels typically limited to one or two days of endurance. San Diego-based Seasats has secured significant Department of War contracts, including deals with the US Marine Corps in 2025 and 2026. The company previously completed record-setting endurance runs and ocean crossings with its proven Lightfish USV platform.

Seasats raises another $20m for uncrewed surface vehicles

Seasats raises another $20m for uncrewed surface vehicles. Seasats has closed a US$20 million Series A financing round to scale the production of its small uncrewed surface vehicles (sUSVs). The funding, led by Konvoy Ventures, brings the total capital raised by the San Diego−based company to more than $40 million. The investment follows the recent award of over $100 million in US government contracts. The funding is intended to support the expansion of new facilities and the development of additional product lines. Seasats currently produces the Lightfish, a 3.5-metre autonomous vessel designed for long-endurance operations. The solar-electric craft weighs 138 kg and has demonstrated its reliability through a 12,000 km autonomous crossing of the Pacific Ocean. The company focuses on automating tasks that are considered unsuitable for crewed vessels. Its platforms are used for tasks such as port security, coastal patrols, and subsea mapping. "Robotics typically deliver value by automating tasks across one or more of the three D's: dirty, dull, and dangerous," said Mike Flanigan, Chief Executive Officer and Co-founder of Seasats. "We've focused on attacking the 'dull' problem, making vessels that can reliably operate for weeks or months, just like Navy and utility ships do. That approach has won tremendous support from users and investors, and this funding underscores that." The company is currently preparing for the launch of its Heavyfish platform, a 4,082 kg long-range vessel expected to be released in autumn 2026. Rob is Chief Network Officer and one of the founders of Smart Maritime Network. He also serves as Chairman of the Smart Maritime Council. Rob has worked in the maritime technology sector since 2005, managing editorial for a range of leading publications in the transport and logistics sector.
