Tel Aviv, Tel Aviv, Israel HyperFi Full time ₪70,000 - ₪120,000 per year

We're building the kind of platform we always wanted to use: fast, flexible, and built for making sense of real-world complexity. Behind the scenes is a robust, event-driven architecture that connects systems, abstracts messy workflows, and leaves room for smart automation. The surface is clean and simple. The interactions are seamless and intuitive. The machinery underneath is anything but. That's where you come in.

We're a well-networked founding team with strong execution roots and a clear roadmap. We're backed, focused, and delivering fast.

We're looking for a Senior Backend Software Engineer to join early. Someone who thrives in fast-moving environments, knows how to balance velocity with sound engineering, and wants to build foundational systems that scale. You'll work closely with the Tech Lead and CTO, contributing directly to architecture, implementation, and internal tooling — and have real influence over how this thing takes shape.

What You'll Do

  • Build and extend core backend services in Python — everything from APIs and MCPs, to event handlers
  • Shape and implement key pieces of our domain model and service boundaries
  • Own integrations between internal systems and external platforms via gRPC and REST
  • Contribute to system architecture alongside the Tech Lead and CTO
  • Work with Postgres and event-driven pipelines, designing schemas and migrations as code
  • Help lay the groundwork for developer tooling, observability, and automated testing
  • Write code that's clean, testable, and built for humans — not just machines

Tech Stack (So Far)

  • Python (async-first, service-oriented)
  • SQL (Postgres), DB-as-code
  • gRPC + REST APIs
  • Message queues (event-driven architecture)
  • Terraform, GitHub Actions, GCP
  • MCP (Model Control Plane) layer for cross-system orchestration

You'll help evolve this stack — we care about getting it right, not being dogmatic.

What We're Looking For

  • 6–8 years of professional experience building production backend systems
  • Strong Python fundamentals, with real-world async or service-layer experience
  • Solid understanding of relational data models, schema design, and SQL optimization
  • Experience designing and consuming APIs — especially gRPC or service mesh patterns
  • Familiarity with software architecture principles, even if you're not "the architect"
  • Comfort navigating ambiguity, collaborating with other senior engineers, and shipping code that matters

Bonus If You:

  • Have worked in an event-driven or event-sourced architecture
  • Are familiar with infrastructure as code (Terraform preferred)
  • Have experience with MCPs, or other orchestration/coordination frameworks
  • Know how to build and evolve a local dev/test environment
  • Can show us something you've built that reflects how you think

Location & Compensation

  • Must be based in San Francisco, Las Vegas, or Tel Aviv
  • Full-time role with competitive comp + meaningful equity
  • Flexible hours, async-friendly culture, engineering-led environment

How to Apply

  • Shoot us a quick note with your background or LinkedIn and something you've built that you're proud of. We'll take it from there. We're looking for people, not pedigrees.

Job Type: Full-time

Experience:

  • Python: 6 years (Required)
