Embedded Software Developer - System Validation
Hubble Network
Hubble Network was founded with the intention of delivering on the promise of what Internet-of-Things (IoT) was supposed to be. We're building a global Bluetooth® network dedicated to machine-to-machine connectivity. We differentiate ourselves as the first modem-less and gateway-less, direct-to-satellite network from off-the-shelf Bluetooth® Low Energy chips. Hubble is ideal for applications in logistics, AgTech, and maritime where economies of scale for volume consumer and enterprise asset tracking is a priority. Our goal is to be the first billion-endpoint-connected network in the world.
Hubble is an early-stage, venture-backed startup supported by some of the best investors in the world. In their previous lives, the founding team has been successful in raising $100s of millions in venture funding, developing the Amazon Sidewalk network, launching billions of dollars of space assets, and leading their teams to successful exits, both through acquisition and IPO. We are now looking to bring on talented team members who are the best at what they do to help us make Hubble a reality for the world.
We are looking for an Embedded Software Developer – System Validation to own and operate two hardware-in-the-loop (HITL) systems. This role sits at the intersection of embedded software, FPGA, and CI/CD automation. You will ensure that both our satellite codebase and end-device SDK are thoroughly validated before deployment, working closely with DevOps and engineering teams.
This is ONSITE in Seattle, WA.
KEY RESPONSIBILITIES
- Own, maintain, and extend two HIL validation systems:
- Satellite HITL: Consisting of FPGA HDL, embedded Linux, and application-layer code in Python.
- End-device HITL: Built on BLE SOMs, validating our SDK for terrestrial and satellite communication (C/Zephyr).
- Develop test strategies and automation to validate embedded software and system-level performance.
- Collaborate with the DevOps team to integrate HIL systems into CI pipelines.
- Create reproducible validation workflows and improve observability of test results.
- Troubleshoot hardware/software integration issues across FPGA, embedded Linux, BLE stacks, and SDK layers.
- Document validation frameworks, test coverage, and best practices.
AN IDEAL CANDIDATE MEETS OUR VALUES:
A Sense of Urgency: Lead projects from concept to reality, rapidly and effectively
First Principles Engineering: Have a strong understanding of the whys behind the whats; have the ability to extrapolate from first principles to complex system design
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
