Ready to shape the future of B2B sales with us? Let's build something great together!
As a Backend Engineer, you'll have real ownership from day one over the engine behind our platform: high-throughput workflows, data pipelines and integrations with the tools our customers live in. You'll make real technical trade-offs and help define how we build as the company scales.
If you enjoy designing systems that hold up under load, debugging the hard stuff and seeing your work directly impact customers, you'll have plenty of room to make a difference here.
Every lead found, every signal detected and every message sent on Enginy runs through our backend. As usage grows, so do the volume, the integrations and the reliability bar and that's the problem space you'll own.
We're looking for an engineer who does more than execute tickets: someone who owns problems end to end, from design to production to observability.
Design → build → ship → observe → scale
We've designed our hiring process to be close to real engineering work. No trivia-heavy interviews and no artificial take-home exercises we focus on how you think through product problems, technical trade-offs, ambiguity, quality, and the use of AI as part of modern engineering.
