Senior Embedded Software Engineer, Harrisburg

Description We build mission-critical software for high-altitude balloon systems, where reliability and real-world performance matter. Our systems operate in demanding environments and interface directly with flight hardware. Aerostar, a business unit of TCOM, is seeking a Senior Embedded Software Engineer to design and develop software that runs on our airborne and ground-based systems. This role focuses on building robust, maintainable embedded software that integrates closely with hardware and supports real-time telemetry, control systems, and mission operations. You will contribute to the development of software across the stack—from low-level hardware interfaces to higher-level application logic—ensuring systems perform reliably in the field. You will work closely with electrical, systems, and software engineers to deliver high-quality embedded solutions and improve the overall reliability and maintainability of our systems. What You’ll Do: Design and implement embedded software for near-real-time systems Develop and maintain drivers, interfaces, and control logic for sensors and onboard systems Contribute to system architecture and technical design for embedded features Write efficient, reliable, and maintainable code in moderately resource-constrained environments Debug and troubleshoot issues across hardware and software boundaries Participate in integration, testing, and validation of embedded systems Identify and address performance, reliability, and maintainability challenges Participate in code reviews and provide constructive feedback to peers What We’re Looking For: You are an experienced embedded engineer who can independently deliver complex functionality in real-world systems. You have contributed to the design and implementation of embedded software and understand the tradeoffs between performance, reliability, and hardware constraints. You are comfortable working close to the hardware. You enjoy solving challenging problems that span software and hardware and collaborating across disciplines. You are pragmatic, detail-oriented, and focused on building systems that work reliably in production environments. You can write software without the assistance of AI but are open to using it to enhance your toolset. Education&Experience: Bachelor’s degree in software engineering, computer engineering, electrical engineering, or a related field, or equivalent experience Typically, 5 years of professional experience in embedded software development Preferred Experience: Rust, C/C++ for embedded systems Linux OS Hardware interfaces (E.g., SPI, I2C, UART, CAN, Ethernet) Working with sensors, radios, or communication systems Experience with high-reliability or mission-critical systems How We Work: We are not a startup, but we operate with ownership and technical rigor. We are building serious aerospace systems, and we expect strong engineering discipline. Strong preference for onsite collaboration. Hybrid may be considered. Remote candidates will not be prioritized. Physical Requirements&Working Conditions: Physical Requirements: Ability to sit, stand, walk, bend, and reach. Reasonable accommodations may be provided for individuals with disabilities. Working Conditions: Primarily in a standard office environment, with occasional exposure to labs and production areas, including noise, fumes, moving machinery, and varying temperatures. Benefits: TCOM 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. Programs and eligibility may vary based on hire date, classification, and schedule.
