Note: The job is a remote job and is open to candidates in USA. World HR Services is a company focused on data enrichment for B2B sales teams. They are seeking a Backend Engineer (Golang) to join a dedicated Growth Squad responsible for rapidly experimenting with backend changes to improve key business metrics.
Responsibilities
- Ship experiments fast. Build and launch backend changes that test a hypothesis — a new pricing nudge, a credit-pack variation, an onboarding tweak, a flow that touches how enrichment results are delivered. Get it live, instrument it, read the numbers
- Work inside the existing system. These experiments don't live on a greenfield. You'll be making targeted changes across an existing Go codebase — including, sometimes, the billing and credit system. Not rewriting it, but reaching into it confidently and safely to test something, then backing it out cleanly if it doesn't pan out
- Promote what works. When an experiment proves its worth, you come back and do it properly — clean up the V1, add the tests, make it production-grade. Knowing what to harden and what to throw away is most of the skill
- Measure everything. An experiment without instrumentation is a guess. You'll wire in the tracking that tells us whether a change actually moved the metric it was supposed to
