Senior Software Engineer Jobs in Boston (No ghost jobs, direct from employers)

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, Wednesday, or Thursday - working together in person and choosing 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.

The Device Connectivity team owns the cloud services that every SimpliSafe base station and camera connects to. We're modernizing those services, moving device messaging onto a new event-streaming platform, and building the connectivity for our next generation of devices. All of this has to stay reliable through our busiest seasonal peaks.

What You'll Do

• Design, build, and operate the C++ and Go services that provide secure, reliable connections between the cloud and SimpliSafe devices and route their messages to the rest of our platform
• Contribute to the shared libraries our services are built on, including metrics, tracing, logging, authentication, and concurrency primitives
• Lead engineering projects end to end, from design doc through staged rollout, zero-downtime production cutover and decommissioning (for example EC2 to Kubernetes, OS upgrades, CI/CD platform changes)
• Help move device messaging onto an event-streaming platform, including a shared event format, schemas and code generation, and load testing
• Build cloud-side connectivity for next-generation devices, including new device capabilities, device provisioning, and certificate management
• Design for reliability at peak load: connection limits, load shedding, connection draining, graceful shutdown, pre-scaling, and multi-region architecture.
• Own observability for the services you work on: distributed tracing, metrics, crash detection, and dashboards and alerts managed as code
• Debug hard production problems across services and AWS infrastructure, lead root-cause analyses, and see the follow-up work through
• Write design documents, review designs from other teams, and work with other engineering teams on features that span devices and the cloud
• Keep services secure and current: certificates and CAs, least-privilege IAM, network policy, fixing security scan findings, and regular releases and dependency updates

What You'll Bring

• 5+ years of professional software development experience
• Very comfortable with AWS (EKS, load balancers, Lambda, SQS, S3, IAM), ideally including IoT Core (MQTT, rules, device certificates), or a similar cloud provider
• Experience managing infrastructure as code with Terraform or OpenTofu
• Experience building and maintaining CI/CD pipelines, ideally with GitHub Actions
• Experience debugging production systems with traces, metrics, and logs (for example OpenTelemetry and Prometheus-style metrics), and leading root-cause analyses
• A track record of leading a migration or large project from design doc through production cutover, and of setting a direction other engineers can follow
• Familiarity with AI-assisted development tools such as Claude Code, GitHub Copilot, or similar

Nice to have

• Strong production experience in modern C++ and/or Go, including async I/O and concurrency
• Hands-on experience running production services on Kubernetes.
• Experience with event-streaming platforms such as Kafka or Pulsar, and with schema formats such as Avro or JSON Schema
• IoT or embedded-adjacent experience, such as device provisioning, PKI for device fleets, or MQTT-based device protocols
• C++ build and library ecosystem experience, such as CMake, Conan.
• Experience with Redis in production
• Experience building networked services that manage many long-lived TCP/TLS connections, including mutual TLS, backpressure, TLS termination
• Experience writing automated integration and end-to-end tests in Python

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.
