Senior Mobile Engineer

Who You’ll Be Joining You’ll join the Mobile Energy team, which owns everything thermostat‑related on mobile, as well as mobile experiences for Energy Services and grid resiliency. Our work sits at the intersection of connected devices, energy intelligence, and real‑world impact — helping customers stay comfortable, save energy, and support a more resilient electrical grid. The team builds and operates core mobile experiences used by millions of customers, working closely with product, design, backend, data, and firmware partners. We ship frequently, operate at scale, and take pride in high‑quality, reliable mobile software. We’re looking for a Senior Mobile Engineer who is excited to work across both iOS and Android (natively), and who strongly leverage AI‑assisted development to move faster, improve quality, and reduce friction in large production codebases. You’ll bring deep expertise in one platform (iOS or Android), with the ability and willingness to contribute meaningfully in the other. This is not a platform‑siloed role — flexibility and collaboration are core to how we operate. Highlights of Our Work Building and evolving mobile experiences that control and monitor smart thermostats and energy programs in real timeShipping features that support energy efficiency, demand response, and grid resiliencyWorking with connected devices over Wi‑Fi, Bluetooth, and cloud‑backed APIsOperating production mobile software at scale, with a strong focus on reliability, performance, and user trustCollaborating closely across iOS and Android to deliver consistent, high‑quality customer experiences What Makes This Role Different: AI‑First Engineering AI is an intentional part of how we build mobile software. In this role, “strong AI expertise” means using modern AI tools (for example, Claude, Copilot or Gemini) and leveraging Agentic AI as a force multiplier in day‑to‑day engineering work You’ll be expected to use AI‑assisted development to: Accelerate feature development and debuggingImprove test coverage and reduce regressionsRefactor and simplify complex or legacy code safelyNavigate unfamiliar areas of the codebase or secondary platform more efficientlyCreate clearer documentation and more maintainable patterns You should know how to validate AI output, apply engineering judgment, and manage risk — using AI as an accelerator, not an autopilot. This role follows a hybrid schedule, with in-office work required on Wednesdays and Thursdays from our Toronto office to support collaboration, and flexibility to work remotely for the remainder of the week. How You’ll Make An Impact You’ll help ecobee move fast, innovate, and deliver high‑quality mobile experiences: Design, build, and operate production mobile features used by millions of customersOwn work end‑to‑end — from technical design and implementation through release and iterationPick up work across iOS and Android as needed to unblock delivery and improve team throughputContribute to and evolve mobile architecture to support scale, performance, and long‑term maintainabilityTake responsibility for production quality, including monitoring, debugging, and incident responseCollaborate closely with product, design, backend, data, and firmware partnersMentor other engineers and help raise the technical bar across the mobile organizationInfluence technical direction and help shape next‑generation energy and thermostat experiencesModel and share effective AI‑assisted development practices across the team We operate in a competitive landscape, and our ability to ship high‑quality mobile software quickly is core to how we win.
