We’re looking for a Senior Java Developer who is interested in building cloud-based solutions with a unique opportunity to build 99.999% available systems - yes, this is correct, what the team is building has a window of not being available for about 5 minutes a year. We’ve put tremendous effort into the design and validation of the software with best practices implemented (from code to final environment in 20 minutes, 24/7 synthetic testing, etc).

The product runs on Azure and AWS cloud infrastructures, and processes emergency (911) calls that save lives so we treat it super seriously. The team owns the tech stack, creates pipelines as code, tests automatically, and deploys with confidence.

Tech stack:

Azure & AWS clouds, Kubernetes/Docker, Java 21, Kotlin, Spring Boot 3.x, Git Hub, Azure Dev Ops, ELK Stack + Prometheus/Grafana, Redis, Mongo

DB, SIP

• Achieving this level of availability (less than 5 minutes of downtime per year) requires significant engineering discipline and constant improvement. You will be part of a team that:
  • Designs and validates fault‑tolerant architectures.
  • Continuously improves performance and reliability.
  • Monitors and fine‑tunes systems around the clock.
  • Owns critical components such as the SIP stack, which you will use and optimize daily.

This is not just about writing code — it’s about building, operating, and evolving a platform where reliability and performance are absolutely critical.

• Develop backend services in Java (21) and Kotlin, applying best practices for scalability, resilience, and maintainability.
• Work directly with the SIP stack, gaining deep knowledge of call routing and handling protocols, and applying it in daily development and troubleshooting.
• Build and maintain automated CI/CD pipelines (as code) with fast, reliable deployments (complete test suite feedback in 20 min).
• Ensure high system reliability through synthetic 24/7 testing, observability, monitoring, and continuous improvements.
• Collaborate with the team on design, development, and performance tuning of cloud-based 911 call routing services.
• Be part of ON CALL support with other team members as 3rd line of technical support.

• You will build and operate systems where reliability is critical and performance directly impacts public safety.
• You will work with modern technologies across multi‑cloud platforms (AWS + Azure).
• You will gain deep expertise in SIP and 911 call routing systems — rare and highly valuable knowledge.
• You will be part of a team that values technical excellence, experimentation, and continuous improvement.

• Strong experience with Java (preferably Java 21) and Spring Boot (3.x).
• Familiarity or interest in Kotlin.
• Experience with cloud environments (Azure, AWS) and containerized workloads (Kubernetes, Docker).
• Understanding of high availability architectures and reliability engineering.
• Knowledge of or willingness to learn SIP protocol and apply it in daily work.
• Hands‑on experience with observability tools (e.g., ELK, Prometheus, Grafana) and databases (Redis, Mongo
  
  DB).
• Strong problem‑solving skills, ownership mindset, and ability to work in a collaborative environment.
• In return for your expertise, we’ll…
