Omada Health is on a mission to bend the curve of chronic disease. Job Overview: We are hiring a Senior Engineering Manager to own a significant piece of Omada's Member-facing surface. You own what gets built, in what order, and how the people building it grow. A squad owns problems from prototype to production, including the maintenance and the on-call rotation for what it ships. At this level you own more than one, which means the hardest calls you make are the ones about where capacity goes when two good things want it at the same time. You stay technical. You are in the codebase and in the same agent workflows your builders use, close enough to review architecture, catch a weak design, and be useful in an incident. Where you manage directly, you ship production work off the critical path. Where you manage through someone else, that person's growth is your work product. You partner with Product Strategists who spend their time in front of members, coaches, and stakeholders, and who prototype to test ideas quickly. They own what gets built and why. You own whether it can be delivered, at what cost, and by when, and you are senior enough that your answer shapes the roadmap rather than just responding to it. About you: You are comfortable being accountable for what your squads ship. You still write code, and you want to. This role ships production work off the critical path, in the same codebase and the same agent workflows as your squads, so you feel the friction your people feel first-hand. You have a point of view on where AI-assisted development helps and where it creates rework, and it comes from changing how a real team works, not from reading about it. You have done the engineering manager job well enough that you can teach it. Whether or not you have carried the title of manager-of-managers, you have grown someone into leading, and you know the difference between doing the work for them and raising their ceiling. Your first team is your peer group, not your

About Us: AI needs a new infrastructure layer. We're building it at Modal. Every era of computing brought new workloads that previous infrastructure couldn't support: mainframes, databases, and the cloud. Each time, the company that rebuilt the layer underneath defined the decade. AI is no different, except it touches everything instead of one slice, and the window to build the layer underneath it is open right now. Our customers include category-defining companies like Ramp , Cognition, DoorDash, and Suno. They rely on Modal for instant GPU access, sub-second container starts, and native storage, so it's simple to serve low-latency inference, fine-tune models, and access production-ready sandboxes at scale. We've passed $1B in annualized run rate, up 15x from a year ago. In October 2026 we raised a $750M Series D led by Accel at a $15.75B valuation. Our team includes creators of popular open-source projects (e.g., Seaborn , Luigi ), academic researchers, international olympiad medalists, and experienced engineering and product leaders with decades of experience.
