Overview

We build cloud CPaaS/CCaaS infrastructure – the routing, messaging and real-time layer that contact centres run on. High traffic, event-driven services, and a UI that has to stay correct while thousands of live conversations move through it. We’re hiring a senior engineer for a team where AI agents are part of the normal development loop, not a pilot. You’ll own features end-to-end across a Go backend and a React/TypeScript frontend, and you’ll be accountable for everything you ship — including the parts an agent wrote. This is not a prompt-engineering role. It’s a senior engineering role where AI-assisted delivery is the default working method.

Responsibilities:
  • Own features end-to-end across Go backend and React/TypeScript frontend;
  • Design and develop solutions for high-load and distributed production systems;
  • Use AI coding agents as an integral part of your everyday development workflow;
  • Guide AI agents, review and verify their output, and take ownership of the final result;
  • Build and evolve backend services, APIs, frontend functionality, and external integrations;
  • Investigate complex production issues and drive them to resolution;
  • Contribute to architecture decisions, technical discussions, and system improvements;
  • Help improve our codebase and development practices to make AI-assisted engineering more effective.
Required Qualifications:
  • 5+ years of professional software engineering experience and strong Senior-level engineering fundamentals;
  • Strong hands-on production experience with Go - 4 years of experience;
  • Practical experience with React and/or TypeScript; you don’t need to be a frontend expert, but you should be comfortable working with frontend code;
  • Hands-on experience with high-load and distributed production systems;
  • Experience designing, building, and debugging production services and APIs;
  • Hands-on experience with AI coding tools such as Claude Code, Cursor, Windsurf, Copilot, or similar - beyond simple autocomplete;
  • Ability to use AI to work effectively across different parts of the stack while critically reviewing and verifying its output;
  • Strong engineering judgement, ownership, and ability to make technical decisions independently.
Benefits:
  • Access to mental health programs, comprehensive medical insurance, and a sports card
  • Enjoy the company of cool teammates, a friendly atmosphere, a strong mentorship, and a variety of bonuses & corporate gifts
  • Benefit from free educational events & courses, and English classes with native speakers
  • Focus on your professional development in a supportive environment
  • Choose your working format - remote, office-based, or hybrid and engage in team-building activities
  • An AI-first engineering environment where AI is part of real production development
  • The opportunity to use AI to work across the full stack and expand beyond your primary expertise
  • Work on high-load communication products with real business impact
  • A team where Senior Engineers influence technical decisions and architecture
  • Remote work
Nice To Have:
  • CCaaS / CPaaS / telecom background: contact-centre routing, ACD, omnichannel messaging.
  • Voice stack: WebRTC, SIP, media servers, or CPaaS APIs
  • API gateway and microservices integration; GraphQL federation.
  • Kubernetes, Docker, CI/CD ownership, infrastructure-as-code.
  • Polyglot persistence: Redis for caching and ephemeral state, PostgreSQL where a document model is the wrong fit; plus the judgement to tell the difference. MongoDB Atlas or self-managed cluster operations.
  • Internal tooling, evals or automation built on LLM APIs.
  • Open-source contributions, especially in Go.
