About The Role:

We are seeking a highly motivated software engineering intern to join the Apolink team in Spring 2026. You can expect to gain hands-on experience writing flight software (mostly C, some Python) for our demo mission planned to launch in June. You’ll be working closely with the engineering team to write and test software at the component and system level while gaining exposure to cutting edge communication protocols. You may also assist the team with simulation and modelling for future missions, satellite assembly, mission planning, or other tasks that align with your skills and/or interests. We don't believe in intern projects, so you will be working on flight critical software alongside seasoned engineers and professionals.

Required Skills/Experiences:

• Prior software intern experience (bonus for satellite experience)

• Hands-on experience with embedded communication protocols (CAN, UART, I²C, SPI, RS-485, etc.)

• Fluency in C/C++

• Comfortable working with vendor SDKs and adapting them to flight software needs

More info:

• Work Type: Full time, In person - Remote candidates will not be considered due to the hands-on work required in this role.

• Role Duration: Jan 2026 - May 2026

• Daily meal credits when in office
