Senior Full Stack Engineer

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
