About the Company/Product
•An AI-driven platform that operates as a Cloud Contact Center as a Service (CCaaS) with a variety of customer experience solutions — voice, messaging, and AI-assisted automation on top of its own telephony layer.
•With offices across Europe, the USA, Brazil, and the UAE, the company’s clientele is already at 350 and counting — and its agents operate in over 60 countries worldwide.
About the Role
We’re looking for a Senior+ Backend Engineer (Java/Kotlin) to reinforce several product squads, each owning a different slice of a large, distributed platform.
Across the teams, the engineering challenges span a wide spectrum, for example:
•Real-time voice — an asynchronous service that manages the live state of voice interactions under continuous load.
•Orchestration at the core of the product — the system that tracks agent availability and state in real time and routes work to whoever can handle it.
•High-volume analytics — very large data stores where smart query and storage design make or break performance.
•Text channels — the services behind written customer communication.
What You’ll Do
•Own features end-to-end — from initial proposals and refinements to code reviews and architectural decisions.
•Keep a large distributed monolith healthy, observable, and fast — working with asynchronous architecture across the system.
•Maintain and evolve existing services while building new ones — new code skews toward Kotlin, existing toward Java.
•Make architectural calls and reason about their impact — on performance, scalability, and reliability.
•Address technical debt systematically — and keep architectural quality high over the long run.
•Ship with engineering rigor — real test coverage, proper observability, and documentation a teammate can actually use.
•Collaborate closely with cross-functional teams — align with product owners and other squads on shared features and integrations.
Tech Stack: Java, Kotlin, Spring Boot (latest versions), Golang, PostgreSQL, RabbitMQ, Redis, OpenSearch, Docker.
What You Have
•7+ years in software engineering at product companies (B2B or B2C), with 3+ years of hands-on Java/Kotlin (preferred).
•Solid Spring Boot experience (latest versions).
•Strong PostgreSQL skills: for data-heavy roles in some of the squads, close to DBA level (design, tuning, troubleshooting at scale) — a big plus.
•Track record designing and running distributed systems in production.
•A self-starter attitude — you love having the autonomy to make high-stakes/high-impact architectural decisions, and you wouldn’t mind growing into a leadership role (Staff/Tech Lead track).
•An SRE-adjacent reflex — you think about reliability and observability as part of building, not after an incident.
•A product-centric mindset — you have high engineering standards, you’re meticulous in your work, and you can see the big picture beyond your specific task.
•Willingness to work with and improve an existing co
