The simulation domain owns York's physics simulator and the model of the spacecraft that flight software is tested against. Alongside it, the interface emulators stand in for real avionics interfaces, an API exposes fault interfaces to manipulate models, and a messenger application attaches for reading and logging simulation messages. This team builds new simulation capabilities, proves they are correct, and authors the mission scenarios that exercise them. When a regression test passes against our simulation, the flight software team needs to be able to trust that the spacecraft would behave the same way in orbit.     In this role you will own our simulation tools products, not just as codebases. That means a real roadmap and release cadence, versioned models and documented interfaces, and clear commitments to the teams that depend on your simulations. You will keep the overall vision of the simulation domain organized and aligned with the requirements of internal and external stakeholders, assuring that quality work gets done in a timely manner. You will foster the growth of all simulation products as well as the engineers on your team building and maintaining them.    Responsibilities  Manage a team of 8-12 engineers with strong leadership skills, including tasking, technical direction, career growth, and performance  Set priorities across the three simulation products, working through a designated engineering lead for each, and grow that structure as the group scales  Own the simulation product roadmaps, release cadences, and versioning strategies    Communicate status, risks, and trade-offs clearly to SIT leadership and internal stakeholders  Interact with stakeholders and customers to gather feedback and requirements for feature requests and bugfixes  Implement and improve software development, testing, and deployment practices that meet division and department standards for software  Ensure quality of product documentation, user guides, training, and model validation records  Manage and monitor releases and ensure products are stable for deployment   Required Qualifications  Bachelor's degree or greater in Aerospace Engineering, Mechanical Engineering, Physics, Computer Science, or related field  8+ years of experience in software engineering or a related field  3+  years of experience leading or mentoring engineers, including tasking and technical direction  Demonstrated development experience in both Python and C++, including performance-sensitive code  Working knowledge of physics-based modeling, numerical methods, or control systems  Experience leading others in software development, whether as a manager, technical lead, or both  Experience designing, building, deploying and operating software applications in a production environment  Experience with software product release processes  Strong communication skills and the ability to set priorities across multiple concurrent products and stakeholders  Ability to communicate technical tradeoffs, priorities, and progress clearly to both engineers and leadership  Experience with writing test documentation, such as test plans, procedures, reports, and defect records   Capable of managing multiple tasks while delivering according to program milestones and release commitments    Desired Qualifications  Experience with both product and people management, including owning a roadmap and release cadence  Background in orbital mechanics, attitude dynamics, or GN&C  Experience emulating hardware interfaces or spacecraft bus protocols  Experience validating simulation models against test or flight data  Experience designing and versioning APIs consumed by other teams  Familiarity with spacecraft flight software and avionics architectures  Experience with real-time or discrete-event simulation frameworks  Experience with Docker and containerization  Experience with Software-in-the-Loop (SITL) and/or Hardware-in-the-Loop (HITL) test systems  Experience in end-to-end, system-level automated testing  Experience with agentic or AI-assisted software development workflows  Ability to interface with and handle flight hardware  Familiarity with the space domain and satellite operations  Networking concepts like UDP/TCP  Active Top Secret security clearance or ability to obtain
