Senior Embedded Engineer - Space Systems

About the Role

We are seeking an experienced Senior Embedded Engineer to architect and implement software for our satellite systems. This is a hands‑on role where you will work closely with our hardware, RF, and operations teams to develop high-reliability embedded software that powers our constellation. You will act as a technical leader on our engineering team, taking system‑level requirements and translating them into robust, efficient embedded solutions that operate in the harsh space environment. This position offers a unique opportunity to work across the full embedded stack: from low‑level device drivers to application‑level software managing satellite operations, all while contributing to the architecture of our next‑generation satellite platform.

Responsibilities

• Write high‑quality, maintainable code in both Python and C for satellite command scripts and performance‑critical embedded applications.
• Design, implement, and maintain embedded Linux systems for satellite payloads, including kernel configuration, driver development, and system optimization for resource‑constrained space hardware.
• Develop and debug device drivers for common interfaces (SPI, I2C, UART, Ethernet) and peripherals including ADCs, DACs, DDR memory controllers, and custom hardware.
• Contribute to the design and implementation of satellite flight software, including command & data handling, telemetry systems, and autonomous operations.
• Lead board bring‑up activities for new hardware, working closely with electrical engineers to validate designs, debug interfaces, and commission new systems.
• Design software with awareness of space‑specific challenges including radiation effects (SEUs, latch‑up), thermal constraints, and power budgets.

How We Work

• Hands‑On Engineering: We value engineers who can move seamlessly between architecture, implementation, and debugging. You'll work with real hardware daily.
• Cross‑Functional Collaboration: You'll interface with RF engineers, digital design engineers, mechanical engineers, and operations staff to ensure software meets system‑level needs.
• Tools: We use modern development tools including AI, Git, Jira, and Confluence. Experience with oscilloscopes, logic analyzers, and JTAG debuggers is essential.

An Ideal Candidate Has

• A Sense of Urgency: Lead projects from concept to reality, rapidly and effectively.
• High Learning Agility: Love to learn; have a grounded approach to recognizing your weaknesses and take the initiative to brush up on and sharpen your engineering foundations to better collaborate with your teammates with different backgrounds.
• System‑Level Design and Analysis: Understand the requirements flow down process and be able to quickly iterate on evolving requirements.
• Excellent Communication Skills: Effectively convey ideas and communicate technical topics with engineering, build staff, and operations; run self‑directed design reviews and participate in reviews of parallel systems.
• Anticipation of Needs: Identify problems, think creatively, and rapidly produce reliable and cost‑effective solutions to meet the ever growing and changing needs of an early‑stage company.

Qualifications

• 5+ Years of Experience: Proven track record of delivering embedded systems for production hardware, preferably in Aerospace, Defense, or other high‑reliability domains.
• Expert‑Level C Programming: Deep understanding of C for embedded systems, including memory management, real‑time constraints, and optimization techniques.
• Expert‑Level Python: Strong Python skills for scripting, automation, test frameworks, and ground system integration.
• Embedded Linux Proficiency: Solid experience with embedded Linux (kernel configuration, device drivers, build root/Yocto, or similar).
• Hardware Interface Experience: Demonstrated ability to work with SPI, I2C, UART, Ethernet, and other common protocols. Experience with ADCs, DACs, and memory interfaces (DDR).
• Hardware Debug Skills: Comfortable using oscilloscopes, logic analyzers, and JTAG debuggers to troubleshoot hardware and software issues.
• Space Systems (Optional): Experience designing for the space environment, including radiation hardening techniques, thermal management, and understanding of single‑event effects.
• FPGA Integration (Optional): Experience interfacing with or developing alongside FPGAs, including familiarity with common communication interfaces (AXI, PCIe, custom parallel buses), register‑mapped peripheral access from embedded Linux or bare‑metal environments, and collaborative bring‑up with digital design engineers.

Why Join Hubble?

• Technical Challenge: Work on embedded systems that operate in one of the most demanding environments—space.
