Senior Software Engineer in Leeds

ecobee Smart Security launched in 2020 to rave reviews, delivering an intelligent, machine-learning-driven platform that helps protect homes and families. Built on advanced sensor technology, it safeguards our customers’ most important asset - their home. And this is only the beginning. We are now bringing our Security and Energy products closer together, building industry-leading features that make homes both safer and greener. This work sits at the heart of ecobee’s future and is evolving fast.

You’ll join the Smart Security Camera team, playing a pivotal role in our UK-based engineering group. The team owns core camera capabilities end-to-end, shipping standout features while running and evolving production systems at scale. You’ll work across a broad slice of the stack, from cloud services (primarily Python and Go) to on-device software and algorithms. Experience with our specific tech stack is a bonus, but what’s more important is possessing strong engineering fundamentals, a curious mind and an adaptable approach to problem solving.

This role follows a hybrid schedule, with in-office work required on 2 days per week at our central Leeds hub to support collaboration, and flexibility to work remotely for the remainder of the week.

• Building AI-driven algorithms for object detection and video analysis
• Designing power-optimised software for next-generation hardware
• Owning production services from deployment through monitoring and optimisation
• Analysing real-world fleet data from tens of thousands of deployed devices to optimise our systems, detect issues, and deliver industry-leading experiences for our users.

You’ll collaborate closely with globally distributed teams across subscriptions, mobile apps, platform services, and energy products.

• Languages: Python (Flask), Go (and a small amount of Java and Typescript)
• APIs: Apollo GraphQL
• Data layer: Postgres, Bigtable
• GCP: GKE, Cloud Run, Pub/Sub, BigQuery, Dataflow
• AWS: S3, Lambda, ECS
• CI/CD: GitHub Actions, CircleCI, ArgoCD
• Infrastructure: Terraform, Helm, Kubernetes

• Build and operate production services across cloud platforms and a globally distributed IoT device fleet
• Own systems end-to-end - from design and implementation through deployment, monitoring, and optimisation
• Take responsibility for production reliability including observability and incident response
• Design and evolve services to meet demanding scale, resilience, and performance requirements
• Influence architecture and technical direction for next-generation products
• Mentor engineers and help raise the technical bar across the team
• Evaluate emerging technologies and help bring the right ones into production

We operate in a competitive landscape, and our ability to move quickly and ship high-quality software is core to how we win.

• Experience building and operating production systems in Python (Go experience is a strong plus)
• Hands-on experience with modern public cloud platforms such as GCP and/or AWS
• Comfortable working with data at scale, including SQL and schema-less databases
• Experience running containerised and serverless workloads in production
• Able to balance delivery speed with reliability, scale, and performance
• Comfortable working in ambiguous problem spaces - especially around scale, concurrency, and optimisation
• Experience working with IoT platforms or large distributed systems is a strong advantage
• Comfortable using AI-assisted development tools (for example, Claude)

Just so you know: The hired candidate will be required to complete a background check.

• Application review. It will happen. By an actual person in Talent Acquisition. We get upwards of 100+ applications for some roles, it can take a few days, but every applicant can expect a note regarding their application status.

• A 30-minute phone call with a member in Talent Acquisition
• A 45-minute virtual interview with the Hiring Manager and a member of the team
• The final interview will be a 90-minute technical deep dive interview with the team (2 engineers)
