We are building a fleet of dual-use multipurpose robotic space vehicles to create the future where maneuvering, upgrading, refueling, resupply and exploration are as routine as they are on Earth. Getting to space and overcoming the gravity well is only half the story. What you do there is the future. We are not building the trains. We are building the machines that lay down the tracks. By developing the foundational capabilities that make sustained, responsive operations possible, we enable a new era of space exploration that strengthens national security and ensures freedom of action in an increasingly contested domain.\nKatalyst Culture:\nWorking at Katalyst is intense, hands-on, and deeply rewarding. You’ll take real ownership and see your work move from concept to operations in an environment where the problems are hard and the impact is real. We value humility, craftsmanship, and doing things the right way, even when it’s harder. You’ll work closely with thoughtful, driven teammates who push each other to do their best. \nWhat You’ll Do \nContribute directly to the design, development, integration, test, and operation of spacecraft software, including flight software, embedded and real-time systems, autonomy, simulation, mission software, and ground systems. \nOwn well-scoped software engineering problems from requirements and architecture through implementation, unit and integration testing, debugging, documentation, deployment, and closure with support from senior engineers. \nWork hands-on with flight and embedded software, Linux environments, C/C++ and Python codebases, simulators, hardware-in-the-loop systems, networking, telemetry, logs, test infrastructure, and real spacecraft interfaces rather than operating only at the documentation layer. \nParticipate in design and code reviews, software integration, simulation campaigns, hardware-in-the-loop testing, anomaly investigations, mission-readiness activities, and operational support; communicate software behavior, risks, assumptions, and decisions clearly. \nCollaborate across GNC, electrical, mechanical, propulsion, systems, mission operations, and test teams to understand software interfaces and system-level impacts on spacecraft behavior and mission performance. \nBuild engineering judgment by comparing expected software behavior, simulations, interface assumptions, timing, telemetry, and test results against hardware-in-the-loop, integration, and operational data, identifying discrepancies, and iterating toward reliable mission software. \nDocument requirements, assumptions, interfaces, architecture, code behavior, test results, procedures, and technical decisions so others can review, reproduce, maintain, test, and integrate the work. \nTake increasing ownership as technical capability grows, progressing from supervised implementation and test tasks toward independent feature-, service-, interface-, or subsystem-level responsibility. \nSupport spacecraft mission execution by helping translate mission objectives and constraints into credible software architectures, algorithms, interfaces, test approaches, operational tools, and mission-support capabilities. \nWhat We’re Looking For \nRequired \nBachelor's degree completed, or expected before start date, in Computer Science, Computer Engineering, Software Engineering, Electrical Engineering, Aerospace Engineering, Robotics, Applied Math, or a closely related technical field. \nStrong academic or project-based grounding in data structures, algorithms, computer architecture, operating systems, embedded or real-time software, networking, software design, controls/autonomy software, or related software engineering fundamentals, with the ability to explain technical reasoning from first principles. \nDemonstrated hands-on software engineering experience through internships, research, student spacecraft or robotics teams, capstone projects, personal projects, open-source work, laboratories, competitive programming, or prior employment. \nAbility to break down ambiguous software problems, identify assumptions and interfaces, design appropriate architectures or algorithms, make reasonable implementation tradeoffs, and validate work through unit tests, simulation, integration testing, hardware-in-the-loop, telemetry, or data. \nClear written and verbal technical communication, including the ability to explain what was personally architected, coded, integrated, tested, deployed, or debugged versus what was completed by a team. \nComfort learning new spacecraft software architectures, interfaces, embedded platforms, tools, protocols, test methods, and mission concepts quickly in an environment where responsibilities may evolve with program needs. \nAbility to collaborate closely with GNC, electrical, mechanical, propulsion, systems, test, and mission-operations engineers and accept direct technical feedback without losing ownership of the problem. \nAbility to comply with applicable export-control requirements and customer-access restrictions. \nYour Ideal Background \nPreferred \nInternship, research, co-op, or project experience in spacecraft, aerospace, robotics, autonomy, embedded systems, real-time software, defense technology, high-reliability software, or another technically demanding environment. \nExperience taking a software feature, embedded application, autonomy component, simulation, service, or interface from concept and design into implementation, integration, test, deployment, or operation and using the results to drive changes. \nExposure to C/C++, Python, embedded or real-time software, Linux, networking, testing, simulation, robotics, autonomy, hardware-in-the-loop environments, flight software, or mission / ground software. \nAdditional Requirements: Must be willing to work hands-on in the office, lab, integration, or test environment as required and to support occasional extended hours during critical test or mission activities. \nCompensation and Benefits: Your base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience. The anticipated salary range for this role is $80,000 - $105,000 annually.\nBase salary is just one part of your total rewards package at Katalyst. You will also be eligible for long-term incentives, in the form of the Employee Stock Option and Equity Plan, as well as a relocation bonus and other discretionary bonuses. You will also receive access to comprehensive medical, vision, and dental coverage, and unlimited Paid Time Off.\nAt Katalyst our work on projects involving the U.S. Department of Defense requires adherence to International Traffic in Arms Regulations (ITAR), 22 C.F.R. Parts 120-130, which requires compliance with U.S. export laws before allowing employees to perform certain positions. Currently, our available roles necessitate access to ITAR-controlled information, and as a result, Katalyst would have to ensure any non-US person is authorized access to ITAR information before the commencement of employment. We are committed to equal employment opportunities and all qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, or national origin.","description_format":"text","description_chars":7399,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":["Contract Manufacturing"],"lifecycle":[{"event":"open","at":"2026-09-11T13:29:32Z"}],"liveness":{"score":20,"band":"cold","label":"Long shot","p_open":1,"p_active":0.444,"p_room":0.45,"age_days":27,"expected_fill_days":17,"reasons":["conf:2","velocity","win:tail","comp:junior"],"computed_at":"2026-09-28T05:45:00Z"},"pay":{"stated_usd_annual":105000,"is_top_pay":false},"html_url":"https://alion.io/job/katalyst-space-recent-graduate-software-engineer-i","json_url":"https://alion.io/job/katalyst-space-recent-graduate-software-engineer-i.json","meta":{"generated_at":"2026-09-29T02:11:13Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":1834,"day_limit":5000,"remaining_today":3166,"minute_limit":60,"resets_at":"2026-09-30T00:00:00Z"}}}
