Job description

About This Roleย 

Spring internships will range between the months of January and May.ย All dates dependent upon the university schedule of the selected students. Internships are full-time and on-site in Los Angeles, CA. To be considered for this internship, candidates must be actively enrolled in an accredited undergraduate or graduate degree program.ย 

As a Software Engineering Intern, you will contribute to the software that powers Varda's missions across ground systems, flight and embedded software, testing and simulation, and developer platform and infrastructure. You will help build tools and services that assist engineers and operators in monitoring, commanding, and analyzing spacecraft, strengthen testing and simulation capabilities, and improve reliability and observability for missioncritical operations.

Internships at Varda are optimal for students looking to grow technically and professionally while working on impactful projects critical to the company's success. We encourage applicants from all backgrounds, including those historically underrepresented in aerospace and software, as well as candidates from nontraditional educational paths. If you are driven by curiosity, motivated to learn fundamentals, and excited to tackle real engineering constraints, we want to hear from you. Even if you don't meet every preferred skill or haven't had access to robotics teams, embedded labs, or maker spaces. We value potential, clarity of thought, and growth mindset, and we're dedicated to providing an experience that will let your decisions and contributions help drive Varda's success.ย 

Responsibilities

You will be paired with mentors across Mission Software, Flight Software, and Embedded Systems, and your projects will be matched to your skills and coursework.

  • Use firstprinciples reasoning to approach problems and justify design tradeoffs.
  • Build Python and/or C++ tools, services, and libraries that interface with flight and ground systems, emphasizing correctness, determinism, and observability.
  • Contribute to automation for simulation, hardwareintheloop, and scenariobased testing.
  • Debug issues that cross abstraction boundaries, including OS behavior, networking, timing, and hardwaresoftware interactions.
  • Collaborate across flight software, embedded systems, mission operations, and test teams; communicate clearly, ask clarifying questions early, and seek support when needed.

Preferred Skills And Experienceย 
  • Familiarity with systems fundamentals including concurrency, networking, performance, and reliability.
  • Exposure to realtime embedded development or safetycritical software, and a working knowledge of math and physics.
  • Experience may come from coursework, personal projects, community college, bootcamps, opensource contributions, internships, or selfdriven learning. We care more about your fundamentals, curiosity, and engineering approach than how you acquired them.
  • Participation in any project work. Whether robotics, rocketry, capstone projects, personal builds, lab work, or opensource contributions. Focus on demonstrating an interest in understanding systems beneath abstraction layers.
Relevant Courseworkย 
  • Computer Architecture

  • Operating Systems

  • Software Engineering / Computer Science Fundamentals

  • Data Structures & Algorithms

  • (Bonus) Signals and Systems
