Senior Backend Software Engineer

About HyperFiWe'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.

About HyperFiWe'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

How We Build

Engineers come first: your time, focus, and judgment are respected

Deep work > chaos: fixed cycles & cooldowns protect focus and keep context switching low

Autonomy is the default: trusted builders who own outcomes, no babysitters

Ship daily, safely: merge early, integrate vertically, ship often, use feature flags, and keep momentum

Outcomes over optics: solve real problems, not ticket soup

Voice matters: from week one, contribute, improve something, and shape how we build

Senior peers, no ego: collaborate in a high-trust, async-friendly environment

Bold problems, cool tech: work on complex challenges that actually move the needle

Fun is part of it: we move fast, but we also celebrate wins and laugh together

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

Confident English skills to collaborate clearly and effectively with teammates

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

Flexible hours, async-friendly culture, engineering-led environment
