About the Role

SimpliSafe's CLV Monitoring Engineering organization is looking for motivated, self-reliant engineers with a backend focus to join our team.

We're building next-generation monitoring experiences that rise head and shoulders above our industry, leveraging our best-in-class technology and our focus on people. 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 backend systems that connect our customers to our Monitoring Center specialists; everything from day-to-day bug squashing to the technical design and architecture of major features and products.

Responsibilities

• Lead technical design for complex backend features, writing design docs, evaluating tradeoffs, and driving decisions on architecture, data models, and API contracts.
• Design and implement backend services in Node.js/TypeScript with a focus on reliability, scalability, and performance.
• Develop and maintain testing strategies to ensure services stay performant and maintainable as they scale.
• Own services end-to-end, from design through production, including observability and resolving performance bottlenecks and technical debt.
• Collaborate with product, design, and other engineering teams to turn ambiguous problems into well-scoped technical solutions.
• Act as a technical lead on projects, setting direction, unblocking teammates, and reviewing designs and code.
• Mentor engineers on technical design and backend best practices.

Requirements

• Experience owning complete features solo within a larger product, or taking full ownership of small products/projects.
• Track record working with product teams to resolve ambiguity and with other engineering teams to design the right technical solution.
• Demonstrated experience owning technical design for medium-to-large systems (design docs, RFCs, architecture proposals).
• Strong grasp of distributed systems, API design, and data modeling.
• Experience building and maintaining scalable, high-availability production services.
• Proficiency in a modern language (TypeScript, C#, etc.) with willingness to learn new tools and languages.
• Proficiency in a modern, cloud-scale NoSQL database.
• Proficiency in implementing modern observability frameworks and logging, and using them to diagnose real issues in production systems.
• Fluency with modern AI tools (e.g., Claude Code, Cursor) across research, design, and implementation, paired with the senior-level judgment to know when they're wrong and to direct, review, and own everything they produce.
• Collaborative mindset, strong customer focus, and passion for learning.

Nice-to-Haves

• Extensive experience with CI/CD and test automation.
• Strong understanding of cloud technologies and practices like infrastructure-as-code and DevOps.
• Experience with tools in our stack (e.g., NestJS, Kafka, Redis, DynamoDB, MongoDB).
• Builds and maintains shared AI tooling and workflows that raise the whole team's output.

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.

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 (For more information on our total rewards please click here)
• 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.
