Senior Full Stack Engineer, AI-First (Go and React)

We’re hiring a Senior Full Stack Engineer for our client, an Israeli product company building cloud platforms for business messaging and contact centres.

About the project

The products help businesses manage customer messages and calls: route conversations to the right agent, connect communication channels, and give support teams tools to monitor activity in real time.

You’ll work on Go services that handle high traffic and React interfaces used to manage thousands of live conversations. The work spans backend services, frontend features, and integrations with communication providers.

The team uses AI coding agents daily. You’ll use tools such as Claude Code or Cursor to develop across the stack, review their output, and take responsibility for the code you ship.

What you’ll do

- Build features across the Go backend and React/TypeScript frontend.

- Design services and APIs for high-load, distributed systems.

- Develop real-time interfaces and external integrations.

- Investigate production issues and improve performance and reliability.

- Contribute to architecture decisions and the team’s development practices.

What we’re looking for

- 5+ years of professional software engineering experience.

- Around 4 years of production experience with Go.

- Working experience with React and TypeScript.

- Experience building and debugging high-load, distributed systems.

- Daily use of AI coding tools beyond autocomplete, including reviewing and testing generated code.

- Ability to make technical decisions independently and follow work through to production.

- Good spoken and written English for technical discussions and everyday collaboration.

The stack

Go, React, TypeScript, REST APIs, GraphQL, WebSocket/SSE, Kafka, NATS/JetStream, RabbitMQ, PostgreSQL, Redis, MongoDB, GCP, Kubernetes, Docker, and CI/CD.

Go and React/TypeScript are the core technologies. You don’t need experience with every tool listed.

Useful additional experience

- CPaaS, CCaaS, telecom, or contact-centre products.

- WebRTC, SIP, media servers, or voice integrations.

- API gateways, GraphQL federation, or infrastructure management.

- Tools, evaluations, or automation built with LLM APIs.

- Open-source contributions, particularly in Go.

Working arrangements

This is a full-time remote role for someone based in Europe, under a B2B contract. You’ll join a distributed engineering team and have a say in how the systems are designed and developed.

Hiring process

After your application is reviewed, the next step is an AI interview. The remaining stages are:

1. An online Go/React coding assessment, approximately 40–50 minutes.

2. A technical interview with the CTO and R&D Director, approximately one hour.

3. A short HR conversation.
