Requirements
  • This position requires the ability to obtain a Top Secret (TS) security clearance, for which U.S. citizenship is needed by U.S. Government
  • Experience using SolidWorks to create 3D designs and associated documentation for fabrication and assembly
  • Expertise with structural, vibration, shock, and thermal analyses using ANSYS
  • Experience with designing to meet specifications, (e.g. compliance with MIL-STD-810)
  • Experience with integration and test activities
  • Demonstrated desire to successfully pursue new challenges, improve and broaden technical skills, seek greater responsibilities, and increase individual value to the organization
  • Capable of effectively working in a team environment, often under tight deadlines
  • Experience in providing information for technical reviews (SRRs, PDRs, CDRs, TIMS).
  • Background should include a Bachelor’s degree and at least 5 years of applicable experience; Master’s degree and at least 3 years applicable experience, or PhD. Equivalent experience will be considered
Responsibilities
  • Interface with the broader hardware team (e.g. electrical, RF) to ensure complete and proper implementation of systems requirements
  • Collaborate with cross-functional teams to understand system requirements and specifications as they relate to assigned tasking
  • Lead efforts to design and implement hardware designs and support assembly, integration, and testing. Activities may include: Decomposition of needs and definition of requirements
  • Creation of detailed 3D CAD (SolidWorks and PDM) models and associated documentation appropriate for fabrication and assembly (e.g. detailed drawings, bill-of-materials)
  • Conducting analyses (Finite element and “back-of-the-envelope”) for structural, shock, vibration, and thermal mitigation
  • Identification/specification of components and vendors
  • Near term tasking may be related to RF systems for airborne applications, but you may be tasked on other applications as needed
Desired Qualifications
  • Active Secret or Top Secret security clearance

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.
