About HyperFi
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 Back End 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. ? 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 Back End 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
