Job Description

Within our Tools and Automation organization, the Test Platform Services (TPS) team builds and operates the platforms and automation that validate SimpliSafe’s end-to-end ecosystem — spanning the full product stack: connected cameras and sensors, base stations, firmware, cloud services, monitoring workflows, and mobile applications. We enable scalable, production-like validation across hardware, firmware, and distributed software systems to ensure our devices behave correctly in real-world conditions and that critical customer journeys function reliably before reaching production. We are seeking a Software Engineer to lead TPS’s technical vision while leading a team of engineers. This role combines hands-on architectural ownership with people leadership, execution accountability, and technical mentorship.

Job Responsibility

  • Establish and execute the long-term architectural vision for scalable validation platforms, including automation, performance, and resilience testing capabilities
  • Partner cross-functionally with Infrastructure, Backend, Firmware, Monitoring, and Product teams to align validation systems with product architecture, roadmaps, and business goals
  • Ensure virtual devices and simulation systems accurately reflect real-world hardware behavior, eliminating drift between physical and virtual environments
  • Build and operate validation platforms that are reliable, observable, cost-efficient, and trusted, with clear metrics to monitor platform health and validation effectiveness
  • Drive continuous performance, scalability, and resilience analysis, proactively identifying system bottlenecks and leveraging data-driven and AI-assisted approaches to improve validation and code quality
  • Grow and lead a high-performing TPS team, establishing engineering standards, embedding shift-left validation practices, and fostering a culture of ownership, accountability, and continuous improvement

Requirements

  • 8+ years of professional software engineering experience building and scaling distributed, cloud-native systems, with end-to-end ownership across the software lifecycle
  • Deep expertise in scalability, reliability, observability, and production-grade system architecture
  • Strong hands-on engineering capability and experience operating infrastructure in AWS (Kubernetes/EKS preferred)
  • Experience building and operating internal platforms or shared engineering systems used across multiple teams
  • Proven experience leading and developing engineers in a player/coach or technical leadership capacity

Nice to have

  • Experience with device simulation, embedded systems, firmware-cloud integration, or IoT environments
  • Experience designing validation, orchestration, performance, load, or resilience testing systems
  • Demonstrated ability to balance long-term architectural vision with pragmatic execution
  • Experience influencing cross-functional engineering strategy in a high-growth or complex distributed systems environment

What we offer

  • A mission- and values-driven culture and a safe, inclusive environment where you can build, grow and thrive
  • A comprehensive total rewards package that supports your wellness and provides security for SimpliSafers and their families
  • Free SimpliSafe system and professional monitoring for your home
  • Employee Resource Groups (ERGs) that bring people together, give opportunities to network, mentor and develop, and advocate for change

Job Responsibility
Job Responsibility
  • Quick team stand-up, one of your team members seem to be working on a problem you worked on before, and offer to pair with them after the stand-up to support
  • Pairing with one of your team members to work on a complex scalability issue together and grabbing a quick bite to re-fuel those pesky braincells in-between coding sessions!
  • Doing a design session with the Product Manager and UX designer for a large upcoming feature that the team should pick up next week. You ask a lot of questions to drill down to the problem we are trying to solve, and suggest some easier solutions that require less effort for the team.
  • The design session triggered some thoughts about other areas of the system that will be affected. You’re doing a quick dive in the affected areas of the code and find some technical debt that might affect the system’s scalability or reliability. You create a brief Jira ticket and tag the Product Manager to help get it prioritised and to ensure it is not forgotten. You also ping the ticket to one of the other domains' tech leads, as you recall them mentioning a similar problem existing in another domain team.
  • Quick catch-up with the Engineering Manager on the teams delivery reliability and how you can help keep Work in Progress (WIP) and Pull Request (PR) review time to a minimum
  • Talking about PR’s, there are actually still a few open. You take the last part of the day to review your teams PRs. There are some great solutions offered, but one of the junior engineers introduced some code that is difficult to maintain and is lacking unit tests. You jump on a quick call with them to explain the issues and why it matters.
