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're a successful, fast-growing startup building complex systems that run on custom Linux platforms in demanding, real-world environments. We're looking for a Linux Kernel Developer who's comfortable working deep in the stack - from drivers and subsystems to boot and memory management - and who wants to own kernel-level quality as our products scale. In this role, you'll design, develop, and debug kernel code and low-level Linux components that power our hardware platforms. You'll work closely with embedded software engineers, systems engineers, and hardware teams to ensure our platforms are stable, performant, and production-ready. This is a hands-on role suited for someone who enjoys solving hard problems close to the metal in a lean engineering organization. What you will do: * Design, develop, and maintain Linux kernel code, including drivers, subsystems, and kernel modules * Port, configure, and optimize the Linux kernel for custom hardware platforms * Write and maintain device drivers for a range of interfaces (e.g., I2C, SPI, UART, USB, PCIe, Ethernet) * Debug and resolve kernel panics, race conditions, memory issues, and other low-level system failures * Profile and optimize kernel and driver performance, including boot time, latency, and power consumption * Work with bootloaders (e.g., U-Boot) and board bring-up for new hardware revisions * Collaborate with hardware engineers during board bring-up and hardware/software integration * Upstream patches where appropriate, and track relevant upstream kernel changes and CVEs * Contribute to kernel configuration, build systems (e.g., Yocto, Buildroot), and CI integration * Document kernel architecture decisions, driver interfaces, and debugging procedures in a way that's practical and reusable ## Related Videos - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Prototyping with Hardware and the Web](https://www.wearedevelopers.com/videos/651-prototyping-with-hardware-and-the-web) - [The best of two worlds - Bringing enterprise-grade Linux to the vehicle](https://www.wearedevelopers.com/videos/67-the-best-of-two-worlds-bringing-enterprise-grade-linux-to-the-vehicle) - [Project Fugu: Extending the web](https://www.wearedevelopers.com/videos/832-project-fugu-extending-the-web) - [Into the hive of eBPF!](https://www.wearedevelopers.com/videos/1199-into-the-hive-of-ebpf) - [Git for Code Reviews](https://www.wearedevelopers.com/videos/429-git-for-code-reviews) ## Related Articles - [What’s the Difference between a Junior, Mid, and Senior Developer?](https://www.wearedevelopers.com/magazine/238-what-s-the-difference-between-a-junior-mid-and-senior-developer) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs)
