Job description

  • Build and maintain backend services in Node.js + TypeScript (REST APIs, background jobs, integrations).
  • Own data flows and reliability: queues, retries, rate limits, caching, and performance.
  • Design and implement database models and migrations, and keep systems observable (logs, metrics, alerting).
  • Ship product features end-to-end, including React UI work when needed.
  • Debug production issues fast, write post-mortems, and harden the system so it does not happen again.
  • Collaborate closely with product and CX to understand the “why” and turn it into working software.


Requirements

We’re a real startup, not a playground. Bootstrapped and fast-growing.

Our motto: Move fast, break things. Chatarmin to the moon.

We build for e-commerce brands in the B2B SaaS space. High pace, high expectations, zero corporate nonsense. We're here to win and so should you be.

We’re looking for a backend-heavy fullstack engineer who can own critical systems end-to-end: APIs, infra-ish backend work, and the React UI that ships the feature.

You should thrive under pressure, work autonomously, and have a hands-on attitude. Think like an athlete: disciplined, self-motivated, and pushing through when it gets tough.


Requirements

  • 3+ years experience shipping production software as a backend or fullstack engineer.
  • Strong Node.js + TypeScript skills, and solid fundamentals (async, concurrency, networking, API design).
  • Experience with common backend building blocks: relational or document DBs, Redis/caching, queues, background workers, third-party integrations.
  • Comfortable in React (and modern frontend tooling) to build and maintain product UI.
  • Pragmatic engineering mindset: you care about reliability, debuggability, and shipping.
  • You take ownership, communicate clearly, and do not need babysitting.

Benefits & conditions

  • Young, highly motivated team with zero ego.
  • Speed over politics: if you have an idea, run with it.
  • Direct impact on the company and the product.
  • Real growth opportunities. We promote from within.
  • Earn what you’re worth: good base pay + performance upside. Your output defines your income.
