The role involves modernizing a legacy platform by incrementally introducing new architecture, building services, and maintaining production stability through collaboration and engineering improvements.
Everbridge is a global leader in critical event management, helping organisations and governments respond to the moments that matter most. We're currently seeking a Software Engineer focused on platform modernisation to help evolve a critical production system while building the next generation of our technology stack. This is a remote/home based role that can be based anywhere in the US.
This role sits at the intersection of legacy system stewardship and forward-looking architecture. You will help ensure our existing platform remains reliable and supportable, while incrementally introducing modern services, patterns, and infrastructure that will shape the future of the platform.
The work involves careful modernization rather than wholesale replacement—extracting services, introducing new capabilities, and reducing technical debt while maintaining production stability.
This role is well suited for engineers who enjoy:
- Improving complex systems
- Incrementally replacing legacy components
- Designing modern architectures that coexist with mature platforms
- Making pragmatic technical decisions that balance innovation with operational reliability
What you'll do:
- Design and implement components of the next-generation platform architecture.
- Build new services and APIs that gradually replace or extend legacy functionality.
- Apply modernization patterns such as:
- Strangler Fig architecture
- Service extraction
- API façade layers
- Incremental data migration
- Introduce modern engineering practices, tooling, and infrastructure where appropriate.
- Maintain and support existing production systems that the business depends on.
- Implement targeted improvements and stability fixes while minimizing unnecessary disruption.
- Identify areas where modernization efforts can reduce operational risk or technical debt.
- Improve observability, documentation, and operational reliability of legacy components.
- Write high-quality, maintainable, and well-tested code.
- Participate in architecture discussions around system evolution and modernization strategy.
- Collaborate with platform, product, and infrastructure teams to deliver incremental improvements.
- Contribute to a culture of continuous improvement and pragmatic engineering.

Engineering and Collaboration
What you'll bring:

- Building scalable microservices
- Experience with CI/CD Pipelines: Terraform, Kubernetes, ArgoCD
- Full-stack development with various programming languages, e.g. Javascript/Typescript, Java, C#, Scala
- Monitoring and observability: Grafana, Datadog
- Experience working with existing systems or mature codebases, not just greenfield development.
- Guiding/mentoring junior engineers
- Strong debugging, troubleshooting, and system analysis skills.
- Familiarity with modern development practices such as:
- version control
- automated testing
- CI/CD pipelines
- Ability to reason about system design, architecture trade-offs, and technical debt.
Preferred Experience
- Experience with system modernisation or platform evolution projects.
- Experience integrating legacy applications with modern services or APIs.
- Familiarity with cloud platforms, containers, or distributed systems.
- Background working in environments transitioning from monoliths to service-oriented architectures.
- Some experience/familiarity with AI software development tools: Codex, Kiro, Speckit
