Founding Senior Software Engineer

About the role

FOUNDING SENIOR SOFTWARE ENGINEER (SF IN-PERSON PREFERRED)

ABOUT HYPERSCALE

Hyperscale is building AGI for physical operations. We're a team of ex-Samsara engineers and operators deploying frontier agentic systems in the real world.

The result is a superagent that autonomously handles the highest-volume, most complex back-office workflows physical operations depend on: load coordination, scheduling, support, finance and billing, and more. We're live with some of the largest fleets in the US, running millions of autonomous tasks each week, with strong customer satisfaction. We're backed by top investors and moving fast.

THE ROLE

We're hiring a Founding Senior Software Engineer who will help build the core product infrastructure that powers Hyperscale's agentic AI platform. You'll work directly with the founders and across the stack - from backend systems to real-time voice interfaces to customer-facing features.

You'll be working on cutting-edge applied AI challenges: building production agentic systems that autonomously handle complex, multi-step workflows in real-world operations. This means solving hard problems in agent orchestration, real-time decision-making, tool use, and human-AI interaction patterns - not just integrating LLM APIs, but architecting the intelligence layer that makes autonomous operations reliable at scale.

This is a broad, hands-on role where you'll own significant parts of the product and have the opportunity to shape our engineering culture from day one. If you like building from zero, shipping fast, and solving hard problems close to real customer impact, this role is for you.

WHAT YOU'LL DO

Engineering across the stack

- Build and own core product features end-to-end, from data models to user interfaces (including conversational/agentic UX)

- Design scalable backend systems that power our AI agents in production environments, including agent orchestration, memory systems, and tool execution pipelines

- Work on real-time communication infrastructure handling thousands of customer interactions

- Ship features that directly impact customer outcomes and business metrics

Infrastructure and reliability

- Build robust, observable systems that handle enterprise-scale workloads with autonomous agents in the loop

- Own deployment pipelines, monitoring, and incident response

- Make pragmatic technical decisions that balance velocity with quality and maintainability

- Establish engineering practices and patterns that will scale with the team

Cross-functional collaboration

- Work closely with founders, customers, and go-to-market teams to understand requirements and iterate quickly

- Translate customer problems into elegant technical solutions, including designing agentic workflows and interaction patterns

- Participate in technical discussions and architecture decisions
