About SimpliSafe

We’re a high-tech home security company that’s passionate about protecting the life you’ve built and our mission of keeping Every Home Secure. And we’ve created a culture here that cares just as deeply about the career you’re building. Ours is a no ego culture of collaboration and innovation where those seeking their next challenge can find big opportunities and make a huge impact on the lives of all those who we protect. We don’t just want you to work here. We want you to grow and thrive here. 

We’re embracing a hybrid work model that enables our teams to split their time between office and home. Hybrid for us means we expect our teams to come together in our state-of-the-art office on two core days, typically Tuesday and Wednesday, to work together in person, and teams can choose where they work for the remainder of the week. We all benefit from flexibility and get to use the best of both worlds to get our work done.

Why are we hiring?

Well, we’re growing and thriving. So, we need smart, talented, and humble people who share our values to join us as we disrupt the home security space and relentlessly pursue our mission of keeping Every Home Secure. 

What You’ll Do

SimpliSafe is looking for a Senior Software Engineer with a backend focus to join our Authorization and Messaging Platform team. We embrace modern software design and craftsmanship, and support and own our work through its entire lifecycle. In this role, you’ll take ownership of the messaging tools and CIAM platform that our engineering staff use every day to build our products that keep our customers safe — everything from day-to-day bug squashing, to the technical design and architecture of authorization and messaging products.

Primary responsibilities include: 

  • Be a technical leader on the team driving design discussions/decisions and participating in code reviews; mentor and coach team junior members on software best practices.
  • Design tailored APIs for seamless user experiences.
  • Encourage innovation by embracing experimentation and fearlessly tackling highly complex challenges.
  •  Establish and maintain testing strategies to ensure long-term performance and maintainability.

What You’ll Bring 

  • Candidates should have experience successfully shipping complex, highly scalable applications that require coordination with other engineering teams and product owners.
  • Experience developing applications with either or both Customer Identity and Access Management (CIAM) systems (Auth0, Keycloak, Cognito, Firebase, etc), or distributed data stores for messaging (Kafka, RabbitMQ, etc)
  • A solid understanding in core web and browser concepts (e.g. how the browser parses and constructs a web page)
  • Writing web services at scale using at least one of Nodejs, Rust, Java, Go, Python
  • Extensive experience with REST and web technology.


  • Previous coding experience in Rust is a huge plus as we are nourishing a Rust ecosystem within the company.
  • Experience working on products in safety-critical environments.
  • Extensive experience as a practitioner of continuous integration & delivery, test automation, etc.
  •  Experience with cloud technologies and relevant methodologies such as infrastructure-as-code, DevOps, etc.

What Values You’ll Share

  • Customer Obsessed - Building deep empathy for our customers, putting them at the core of our work, and developing strong, long-term relationships with them.
  • Aim High - Always challenging ourselves and others to raise the bar.
  • No Ego - Maintaining a “no job too small” attitude, and an open, inclusive and humble style.
  • One Team - Taking a highly collaborative approach to achieving success.
  • Lift As We Climb - Investing in developing others and helping others around us succeed.
  • Lean & Nimble - Working with agility and efficiency to experiment in an often ambiguous environment.

We wholeheartedly embrace and actively seek applications from all individuals, no matter how they identify. We are committed to cultivating a diverse and inclusive workplace, and we believe our work is enriched when we incorporate a multitude of perspectives, backgrounds, and experiences. We want everyone who works here to thrive and contribute to not only our mission of keeping every home secure, but also to making our workplace safe and supportive for others.
