The posting

Senior Full Stack Developer — Build the Future of Business Communication

Stack: Node.js · MongoDB · VueJS . GCP

The opportunity

We're building new features for a business communication and customer support platform used by companies around the world — and we want a senior full stack developer at the heart of that work.

You'll work side-by-side with our CEO. No Slack queues, no layers of product managers. Just you, the CEO, and the codebase — shipping real features that shape how billions of conversations happen between businesses and their customers.

Our CEO is hands-on, and obsessed with how the craft of building software is changing. AI coding assistants, agentic tooling, modern dev workflows — he uses them daily and expects you to as well. This isn't a place where engineers roll their eyes at AI-assisted development or insist on doing things the way they did in 2015. We move at the speed the new tools allow.

What you'll do

Architect and ship backend services that power live messaging, automations, and support tooling at global scale. Design APIs, tune MongoDB against real production data, deploy on GCP, own features end-to-end. Write clean code, ship it, iterate. No hand-holding. Some new features are already at the prototype stage, and need your skills to connect the backend and go live.

What we're looking for:

Strong hands-on Node.js — you've shipped real production services. Deep MongoDB knowledge — schema design, indexing, aggregation, performance tuning. Comfortable on GCP — Cloud Run, Pub/Sub, Cloud Functions, IAM.

Familiar with VueJS and can show working experience.

Fluent with modern AI dev tools — Claude Code, Cursor, Copilot, agentic workflows. You use them to ship faster, not as a gimmick.

A real shipping record — features in production that users actually touch.

Curiosity — you read changelogs, try new tools, update your workflow when something better lands.

Clear written English and a collaborative style.

Who this isn't for:

If AI-assisted coding makes you roll your eyes, or you've written code the same way for five years with no interest in changing — this won't fit. We want builders who are still hungry, still learning, and still excited about what they can ship this quarter that wasn't possible last year.

Nice to have: Real-time systems (WebSockets, queues, pub/sub)

Background in customer support, chat, or communication platforms

Docker, CI/CD, observability tooling

How to apply:

Send your CV, links to backend work you're proud of, and a short note on the most interesting backend problem you've solved recently. Bonus points for how AI tools have changed the way you build. We reply within 48 hours.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
