Senior Backend Engineer – Growth & Experimentation
About the Company
We’re a profitable, rapidly growing B2B SaaS company helping sales and go-to-market teams find accurate contact and company data for their target accounts.
Our platform combines data from 20+ sources to provide high-quality enrichment and coverage to thousands of businesses. We’re a lean, international team with a strong product and engineering culture, operating across North America and Europe.
This is an opportunity to join a brand-new Growth Engineering squad and have direct ownership over backend systems that impact activation, conversion, retention, and revenue.
About the Role
We’re looking for a Senior Backend Engineer with 5+ years of experience, with strong expertise in Go/Golang, to own the backend experimentation engine behind our growth initiatives.
You’ll work closely with a Product Manager and frontend engineer to launch experiments quickly, measure their impact, and iterate based on real customer and business data.
This is a highly hands-on role where you’ll work directly on important product flows and have significant ownership over the backend.
What You’ll Do
- Ship backend experiments directly into production at a high pace.
- Build and test pricing, onboarding, activation, and credit-related experiments.
- Own critical backend functionality around payments, authentication, signup/login, and credit usage.
- Instrument systems with analytics and metrics to understand experiment performance.
- Partner closely with Product and Design to prioritize and execute A/B tests.
- Turn successful experiments into clean, production-grade systems.
- Remove or iterate on experiments that don’t deliver results.
- Improve backend performance, reliability, and scalability as the product grows.
- Contribute to technical decisions and help shape engineering practices within the Growth squad.
What We’re Looking For
- 5+ years of backend software engineering experience.
- Strong professional experience with Go/Golang.
- Solid experience with PostgreSQL and backend data systems.
- Experience building and operating production APIs and distributed systems.
- Comfortable working with analytics, instrumentation, and experimentation.
- Strong product mindset — you care about business outcomes, not just shipping code.
- Comfortable moving quickly and iterating directly in production.
- Experience working closely with Product, Design, and other engineering functions.
- Strong ownership and ability to operate independently.
Tech Stack
Go/Golang, PostgreSQL, OpenSearch, Docker, GitHub Actions, Grafana, and cloud infrastructure.

Why Join?
