Backend Engineer (Golang)

Role Overview

You’ll join a newly formed Growth Squad to run high-tempo experiments that improve key business metrics. This role focuses on the backend half of the squad, working closely with a frontend engineer and coordinating with teammates in Europe and the US West Coast.

Responsibilities

• Ship and launch backend experiments fast by building backend changes that test a hypothesis (e.g., pricing nudges, onboarding tweaks, credit-pack variations, enrichment result delivery flows).
• Work inside an existing Go codebase with targeted changes (including sometimes the billing and credit system), with the ability to safely back out when experiments fail.
• Promote what works by hardening successful experiments into production-grade improvements (clean up V1, add tests, improve reliability).
• Instrument everything by wiring in tracking to measure whether changes moved the intended metrics.
• Execute experiments directly in production—run several experiments per week, keeping those that work and killing the rest.

Requirements

• 5+ years of backend experience
• Strong Go backend development experience
• Experience building and evolving services via REST and gRPC APIs
• Working knowledge of event-driven architecture
• Hands-on experience with PostgreSQL

Nice-to-Haves / Context

• Comfort working in and modifying existing systems (not greenfield rewrites)
• Ability to iterate quickly and safely in an experimentation-driven environment

Compensation & Logistics

• Salary: $130K–$150K
• Visa sponsorship: Not available
• Remote policy: Eastern Time Zone (ET)
