Embedded Software Engineering Intern

Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place!

E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service delivery associated with traditional satellite and terrestrial IoT systems. We’re intentional, we’re unapologetically curious and we’re 100% committed to innovate space-based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life.

We are looking for an Embedded Software Engineering Intern to work on real firmware for real hardware that ships. You will be embedded (pun intended) with a senior firmware engineer working on a sensor-rich, wireless-connected IoT device: writing production C on Zephyr RTOS, bringing up sensors, debugging on live boards at the bench, and moving data from the edge to the cloud.

• Write and debug firmware in C on Zephyr RTOS for Arm Cortex-M class MCUs.
• Work on sensor integration and sampling pipelines — IMUs, accelerometers, microphones, temperature sensors — over I2C, SPI, and I2S.
• Build, flash, and debug boards daily using West, CMake , SWD/J-Link, and serial consoles.
• Contribute to edge-to-cloud connectivity:
  Wi-Fi, MQTT over TLS, and low-power wireless protocols such as Thread and BLE.
• Help collect and validate sensor datasets that feed on-device machine learning models, and assist with deploying and evaluating those models on target hardware.

• Write unit and integration tests alongside your feature code — we test what we ship.
• Build and improve bench tooling: flash/serial automation scripts, data-capture harnesses, and hardware-in-the-loop test setups.
• Reproduce, instrument, and root-cause bugs on real hardware, and document what you find so the next engineer doesn't hit it twice.

• Participate in design discussions and code reviews — your code gets reviewed, and you review ours.
• Work directly with hardware and systems engineers when the bug turns out not to be in software.
• Present your work at the end of the internship: what you built, what you learned, and what you'd do differently.

• Currently pursuing a BS or MS in Computer Engineering, Electrical Engineering, Computer Science, or a related field.
• Solid C programming fundamentals: pointers, memory, bit manipulation, and comfort reading a datasheet.
• Exposure to microcontrollers through coursework, projects, clubs, or prior internships (Arduino/ESP
  32/STM
  32/Nordic all count).
• Basic Git fluency: branching, commits, and pull requests.
• Comfort with the command line and at least one scripting language (Python preferred).
• Curiosity and persistence. Embedded debugging rewards people who keep pulling the thread.
• Ability to work on-site in Arlington, TX for the duration of the internship.

• Coursework or projects involving an RTOS (Zephyr, FreeRTOS ) or bare-metal firmware.
• Familiarity with communication buses (I2C, SPI, UART) and reading signals on a logic analyzer or oscilloscope.
• Exposure to signal processing (FFTs, filtering) or machine learning basics — our devices run inference at the edge.
• Experience with networking concepts: sockets, TLS, MQTT/HTTP, or wireless protocols.
• A personal project you can talk about in depth — hardware or software.

In your first two weeks, you will have a working development environment, a board on your desk, and your first merged pull request. By the midpoint, you will own a small feature or tooling improvement end-to-end — design, implementation, tests, and review. By the end of the internship, you will have shipped work running on live hardware in the field or on the bench test rack, and you will be able to explain the full path your data takes from sensor to cloud.

• On-site, collaborative environment. We build physical hardware — presence matters.
• Small teams with…
