EVONA · Littleton, Colorado
Embedded Software Engineer
Littleton, CO
Salary:
$130,000 – $175,000
About the Opportunity
Join an innovative space technology that designs, builds, and operates a diverse range of small satellite systems supporting space-based turnkey missions for several business applications, including earth observation, communications, in-orbit demonstrations, risk reduction, science, and exploration. The company is headquartered in Littleton, Colorado with roughly 100 employees and infrastructure around the globe.
We move fast, deliver on time, and continuously improve systems in orbit and on the ground. We value engineers who take ownership, think in systems, and iterate toward robust solutions.
Position Summary
We are seeking an Embedded Software Engineer to develop low-level software that directly interfaces with hardware across spacecraft subsystems and supporting electronics.
This role is well-suited for an engineer with solid foundational experience who can operate independently on day-to-day tasks, while continuing to grow in system design and large-scale integration efforts with guidance from senior engineers.
Candidate will be expected to deliver working software quickly, contribute to hardware bring-up and debugging, and build a deeper understanding of how individual components interact within larger systems. This role is primarily on-site at our Littleton, Colorado headquarters or at our facility in San Jose, California, with limited remote work flexibility.
Primary Duties &
Develop and maintain embedded software for spacecraft subsystems, including sensors, actuators, power systems, and communication interfaces
Write and debug low-level drivers and board support code
Interface directly with hardware (SPI, I2C, UART, GPIO, DMA)
Support hardware bring-up and debugging using lab equipment and standard tools
Deliver working implementations quickly and iterate to improve reliability, performance, and maintainability
Debug embedded systems using tools such as GDB, JTAG, and SWD
Collaborate with cross-functional teams to define and refine system interfaces
Participate in integration, HIL testing, and system validation
Contribute to Python-based test, automation, and data analysis workflows
Minimum
Bachelor's degree in EE, CE, CS, or related field
Proficiency in C and modern C++
Experience developing firmware in bare-metal or minimally abstracted environments
Interrupt-driven design
Memory-mapped I/O and peripheral configuration
Timing and resource constraints
Experience writing low-level drivers and interfacing with hardware peripherals (SPI, I2C, UART, GPIO, DMA)
Ability to work from datasheets/reference manuals to configure and debug hardware
Software tools (e.g., GDB, JTAG/SWD)
Lab equipment (oscilloscope, logic analyzer, multimeter)
Familiarity with RTOS concepts (threads, scheduling, synchronization)
Exposure to embedded Linux development environments
Ability to execute well-scoped tasks independently and deliver reliable results
Preferred
Experience developing firmware for resource-constrained microcontrollers in bare-metal environments
Comfort working at low levels of abstraction, including direct register manipulation and hardware bring-up
Experience with RTOS frameworks (e.g., Zephyr, FreeRTOS) and associated design trade-offs
Familiarity with embedded Linux tools and workflows (e.g., cross-compilation, build systems)
Experience bringing up new hardware, including initialization and early-stage debugging
Familiarity with ARM-based platforms (Cortex-M, Cortex-A) or similar
Exposure to CI/CD or automated testing workflows
What We Value
Ownership of day-to-day work:
Candidate reliably executes assigned tasks and follows issues through to resolution
Growth mindset:
Candidate actively develops technical depth and takes on increasing responsibility over time
System-oriented thinking:
Candidate seeks to understand how components interact within a larger system, including trade-offs and dependencies
Curiosity and critical thinking:
Candidate asks \"why\" when appropriate—challenging assumptions, clarifying requirements, and improving designs
Bias toward action:
Candidate delivers working solutions quickly and iterates based on testing and feedback
Collaboration:
Candidate works effectively across disciplines and incorporates feedback from more experienced engineers
Pay Transparency
Astro Digital employees are provided with a comprehensive benefits package that includes company stock options, healthcare, 401k retirement plan, and PTO. The range of possible compensation for this role is $130k–$175k annually, depending on experience and alignment.
