Then you’ve come to the right place!\n\nE-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.\n\nWe’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.\n\nWe'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.\nIn 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.\nThis is a hands-on role suited for someone who enjoys solving hard problems close to the metal in a lean engineering organization.\nWhat you will do:\nDesign, develop, and maintain Linux kernel code, including drivers, subsystems, and kernel modules\nPort, configure, and optimize the Linux kernel for custom hardware platforms\nWrite and maintain device drivers for a range of interfaces (e.g., I2C, SPI, UART, USB, PCIe, Ethernet)\nDebug and resolve kernel panics, race conditions, memory issues, and other low-level system failures\nProfile and optimize kernel and driver performance, including boot time, latency, and power consumption\nWork with bootloaders (e.g., U-Boot) and board bring-up for new hardware revisions\nCollaborate with hardware engineers during board bring-up and hardware/software integration\nUpstream patches where appropriate, and track relevant upstream kernel changes and CVEs\nContribute to kernel configuration, build systems (e.g., Yocto, Buildroot), and CI integration\nDocument kernel architecture decisions, driver interfaces, and debugging procedures in a way that's practical and reusable\nWhat you bring to this role:\n5+ years of experience developing in C, with deep familiarity with Linux kernel internals\nProven experience writing and debugging Linux device drivers and kernel modules\nSolid understanding of:\nKernel subsystems (memory management, scheduling, filesystems, networking)\nLinux boot process and bootloaders\nConcurrency, locking, and interrupt handling in kernel space\nExperience with embedded Linux build systems (Yocto, Buildroot, or similar)\nComfort working directly with hardware during bring-up, debugging with tools like JTAG, oscilloscopes, or logic analyzers\nStrong debugging skills using tools such as gdb, ftrace, perf, kgdb, or crash dump analysis\nComfortable working independently and taking ownership in a lean startup environment\nBonus points for the following:\nUpstream Linux kernel contribution experience\nExperience with real-time Linux (PREEMPT_RT) or other real-time operating systems\nFamiliarity with security-hardening practices for embedded Linux (secure boot, kernel hardening)\nExperience with version control systems (Git) and kernel patch workflows (mailing lists, git send-email)\nExposure to multiple CPU architectures (ARM, RISC-V, x86)\nExperience with CI/CD pipelines for embedded or system-level software\n$150,000 - $225,000 a year\n\nThis is a full time, exempt position, based out of our Saratoga office. The total compensation packaged will be determined by various factors such as your relevant job-related knowledge, skills, and experience.\nWe are redefining how satellites are designed, manufactured and used—so we’re looking for candidates with passion, deep knowledge and direct experience on LEO satellite component development, design and in-orbit activities. If that’s your experience – then we’ll be immediately wow-ed.\nE-Space is not currently able to provide employment sponsorship for candidates who do not hold work authorization for the location of this role.\n\nWhy E-Space is right for you:\n\nAs a member of our team, you will play a crucial role in driving our success. Our team members have a strong sense of dedication and responsibility; this includes a strong commitment to our mission to create an entirely new suite of global capabilities to improve lives, business efficiencies and build a smarter planet. This means that there will be times when extra hours, including nights and weekends, may be needed to meet critical deadlines and mission goals. In return, we offer a dynamic work environment with opportunities for professional growth and development and the chance to make a meaningful impact in a high-growth industry.\n\nWe want you to make the most of your journey at E-Space. That’s why we support and invest in the physical, emotional and financial well-being of our team members and their families. Some of what you can expect when working at E-Space:\n\nAn opportunity to really make a difference\nSustainability at our core\nFair and honest workplace\nInnovative thinking is encouraged\nCompetitive salaries\nContinuous learning and development\nHealth and wellness care options\nFinancial solutions for the future\nOptional legal services (US only)\nPaid holidays\nPaid time off\n\nWe may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
