Our users are trained operators—primarily U.S. military and internal flight operations teams—who rely on our tools to make real-world decisions. Aerostar, a business unit of TCOM, are looking for a Principal Software Engineer who can lead the engineering behind our production-grade single-page applications and the services that power them. This role is about more than implementing features. It is about shaping the architecture of complex web applications that integrate real-time telemetry, operational data, and mission workflows.\n\nYou will be responsible for designing and building systems across the full stack—from frontend application architecture to backend services and APIs. You will serve as a technical thought leader within the engineering team, helping guide system design, engineering standards, and long-term maintainability.\n\nThis role requires someone who can move comfortably between frontend and backend work, design robust systems, and help other engineers raise the quality of their work.\n\nWith demonstrated success, this role can evolve into formal technical leadership and architectural ownership across our software systems.\n\nWhat You’ll Do:\n\nArchitect and implement the core systems that power our complex, data-driven SPAs\nDesign backend services, APIs, and data flows that support real-time telemetry and operational workflows\nLead technical design for full-stack features, ensuring maintainable and scalable implementations\nEstablish and advocate for engineering patterns, architectural standards, and code quality practices\nMake foundational decisions around application structure, service boundaries, and system integration\nIdentify and address performance, reliability, and maintainability challenges across the stack\nConduct architectural and code reviews to elevate the engineering quality of the team\n\nWhat We’re Looking For:\n\nYou are an experienced engineer who thinks in systems, not just features.\n\nYou have personally designed and implemented significant portions of production software systems and can explain the architectural decisions behind them.\n\nYou enjoy solving complex engineering problems and helping other engineers improve through thoughtful design discussions and code review.\n\nYou can write software without the assistance of AI but are open to using it to enhance your toolset.\n\nEducation & Experience:\n\nMinimum of a bachelor’s degree in software engineering, in field related to specific position.\nExpert engineer with 12+ years of career experience, 10+ years with master’s degree in software engineering.\n\nPreferred experience:\n\nPython familiarity\nTypeScript\nComplex data visualization\nEstablishing or contributing to design systems\nWorking on operational or decision-support tools\n\nWe are building mission-critical operational software. Clarity and usability matter because decisions depend on them.\n\nHow We Work:\n\nWe are not a startup, but we operate with ownership and technical rigor.\n\nWe are building serious aerospace systems, and we expect serious engineering discipline.\n\nStrong preference for onsite collaboration. Hybrid may be considered. Remote candidates will not be prioritized.\n\nPhysical Requirements & Working Conditions:\n\nPhysical Requirements: Ability to sit, stand, walk, bend, and reach. Reasonable accommodations may be provided for individuals with disabilities.\nWorking Conditions: Primarily in a standard office environment, with occasional exposure to production areas, including noise, fumes, moving machinery, and varying temperatures.\n\nTCOM offers a variety of benefits, including health and disability insurance, 401(k) match, flexible spending accounts/HSAs, EAP, tuition reimbursement, parental leave, paid time off (PTO), and company-paid holidays.
