Senior Software Engineer - Backend
Summary
Senior Backend Engineer building core systems like onboarding, messaging, and notifications for a high-scale consumer platform using scalable, low-latency services.
We’re hiring a Senior Backend Engineer to join a small, high-caliber team building a high-scale consumer platform.
You’ll be working on core application-level systems like onboarding, messaging, notifications, and other customer-facing workflows that directly shape how users interact with the product.
What You’ll Work On
- Design and build end-to-end backend systems that power critical user workflows
- Own application architecture, including API design, data modeling, and service boundaries
- Build scalable, low-latency services that support real-time user interactions
- Define and implement authorization models, permissions, and user-level access patterns
- Design systems that handle concurrency, consistency, and reliability at scale
- Work closely with product and design to translate user needs into robust backend systems
What We’re Looking For
We’re looking for engineers who have:
- 4+ years of experience building backend systems in production
- A track record of owning systems end-to-end - from design through to production
- Experience building and scaling APIs that directly support product features
- Strong understanding of application-layer challenges (data modeling, permissions, workflows, consistency)
- Experience working on high-traffic or real-time systems
Why This Role
- Real ownership: design systems, not maintain existing ones
- Work on a product built for high scale from day one
- Small, highly technical team: high impact, high autonomy
