  • Proficient at technical writing
  • Ability to interact with technical and non-technical customers and external teammates to understand their technical issues, frame potential solutions, and develop collaborative projects
  • Scientific curiosity and creativity
  • Skills in C/C++, Python, and/or MATLAB
Responsibilities
  • Apply advanced knowledge of undersea system domains (acoustic, mechanical, electrical, thermal) to define, develop, and validate novel solutions to complex and broad problems
  • Lead the conceptualization, analysis, design, and development phases of new undersea technical solutions (algorithms, processing, test approaches, system or mechanical designs, etc.)
  • Lead and manage moderate size engineering teams (5-10 engineers) through complete project lifecycles including task definition, delegation, and progress tracking
  • Oversee software, hardware, and system design reviews, ensuring adherence to best practices and requirements
  • Proactively evaluate and adopt cutting-edge tools, methods, and processes to enhance engineering outcomes
  • Initiate and lead cross-disciplinary collaborations, identifying opportunities across diverse technical domains, stakeholders, other projects, and customer bases
  • Clearly communicate complex concepts, vision, and strategy through technical presentations and reports to diverse stakeholders, ensuring alignment and understanding at all organizational levels
  • Independently plan, coordinate, and lead laboratory evaluations and at-sea field tests
Desired Qualifications
  • Active Top Secret (TS) security clearance
  • Specific experience with developing low-latency, responsive acoustic systems such as active sonar systems, acoustic ranging/localization systems, echo-repeater testing systems, and/or acoustic counter-measures
  • Experience using modeling and simulation to set system performance expectations for advanced undersea acoustic systems
  • Experience interacting with U.S. Navy and other U.S. Government organizations and processes
  • Knowledge of one or more of the following topic areas: Underwater acoustic propagation modeling; acoustic communications; UUV design, design tools, and component technology; architectures for unmanned systems; sensor, source, and array design (towed, conformal, drifting, or bottomed)
  • Experience with field testing, especially at-sea testing including system deployment, operation, and recovery operations

STR uses AI to help national security and defense clients make faster, data-driven decisions. Its flagship STR infokit platform combines data science, AI algorithms, data conditioning, and DevOps to deliver real-time decision support for use in command and control, collaborative autonomy, and object recognition and tracking. Revenue comes from government and defense contracts for advanced AI platforms that blend artificial and human intelligence to resist manipulation. The company differentiates by emphasizing autonomy, creativity, and diversity to foster robust decision-making under high-stakes conditions, aiming to provide clients with a reliable edge in security challenges.

Simplify's Take

What believers are saying

  • DARPA AIR contract advances STR's swarming uncrewed aircraft AI capabilities and market positioning.
  • Government demand for cybersecurity and distributed sensing solutions expands STR's addressable market.
  • STR's isolated network capability differentiates it in classified government environments with connectivity constraints.

What critics are saying

  • Palantir's AIP platform displaces STR's infokit in DoD decision support with faster deployment.
  • DoD slashed DARPA AI funding 25% in FY2027 NDAA, stalling STR's flagship AIR contract.
  • Anduril's Lattice platform captured $1.5B DoD contracts, outpacing STR in autonomous swarming technology.

What makes STR unique

  • STR's analytics platform delivers real-time sensemaking on isolated networks without external connectivity.
  • STR combines human creativity with AI algorithms for resilient decision-making resistant to manipulation.
  • STR specializes in collaborative autonomy and object recognition for command-and-control applications.
