Junior Embedded Software Engineer

About Observable Space At Observable Space, we're redefining how humanity observes and connects with the universe. We're a vertically integrated, high-growth, space technology company building industry-leading precision optics platforms for Earth and in space. Our systems are trusted by NASA, JPL, SpaceX, Boeing, Raytheon, and the US DoD, among others, and power the work of leading research institutions. We combine precision opto-mechanical hardware, embedded computing, cloud orchestration, and developer-friendly APIs into world class products. From advanced ground stations, on orbit sensor suites, free space optical lasercom, to distributed compute platforms, we deliver the foundational systems enabling continuous, real-time navigation, observation, and communication in space. Observable Space is backed by top-tier institutional investors including Lux, Upfront Ventures, RTX Ventures, Detroit Venture Partners and Embedded Ventures. The Role As a Junior Embedded Software Engineer, you'll work alongside our embedded team across our full product line, from robotic ground telescopes to on-orbit compute platforms. You'll help build and maintain embedded Linux systems and low-level firmware, bring up hardware peripherals, write and debug drivers, and pitch in on the bench work- soldering, test rigs, and prototype assembly- that keeps hardware programs moving. This role is hands-on from day one: you'll read schematics alongside senior engineers, get exposure to electrical and mechanical teams, dig into real hardware debugging, and grow your understanding of edge compute at the cutting edge. You will report to the Embedded Engineering Lead, with close mentorship from senior and staff engineers on the team. Key Responsibilities Support the development, testing, and debugging of embedded Linux systems and low-level firmware- from daemons and drivers to bootloaders and control loops under the guidance of senior engineers. Assist in developing and maintaining drivers across interfaces such as PCIe, SPI, I2C, UART, MIPI CSI-2, and GPIO, under the guidance of senior engineers. Help bring up peripherals (cameras, sensors, communication links) at both the software and hardware level — from firmware and embedded Linux integration to assembling first article prototypes, soldering, wiring, and initial power-on checks alongside the EE team. Help own component test characterization campaigns, from setting up test rigs to running the tests and pulling results together. Participate in longevity testing campaigns and analyze the resulting test data to catch issues before they matter. Participate in design reviews, code reviews, and team discussions to build your product and reliability instincts. Basic Qualifications 0–2 years of experience in embedded software engineering, systems-level development, or a related internship/academic background. Experience in C and working knowledge of C++. Foundational understanding of common hardware interfaces (I2C, SPI, UART, CAN, Ethernet) from coursework, personal projects, or internships. Comfort reading basic schematics or a strong willingness to learn. Familiarity with basic lab tools (multimeter, oscilloscope) or eagerness to build that skill on the job. Strong debugging curiosity and persistence- you enjoy digging into why something isn't working. Good communication skills and comfort asking questions and collaborating closely with senior engineers. A bias toward hands-on learning and fast iteration. Bonus Qualifications Ability to solder and build a wire harness. Ability to use a multimeter and oscilloscope. Exposure to firmware development on microcontrollers (e.g., bare-metal, RTOS, or Arduino/STM32/ESP32-style projects) from coursework, personal projects, or internships. Exposure to Linux kernel development, device drivers, or embedded Linux (Yocto, Buildroot). Personal, academic, or internship projects involving PCIe, MIPI CSI-2, or other high-speed interfaces. Familiarity with Zephyr RTOS or other embedded operating systems. What We Offer Competitive Compensation – A salary package aligned with industry standards and your experience.
