Founding Senior Software Engineer

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.

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
• Help evaluate and integrate new technologies and tools across the rapidly evolving AI landscape
• Team and culture building
• Set the bar for code quality, system design, and engineering excellence
• Mentor and collaborate with engineers as the team grows
• Shape our engineering culture, processes, and technical standards
• Contribute to hiring and building out the engineering team

Who You Are

• 5+ years of software engineering experience, with demonstrated ability to build and ship full-stack applications
• Strong fundamentals in backend systems, databases, APIs, and web applications
• Comfortable working across the stack and learning new technologies quickly
• Track record of owning complex features or systems from design through deployment
• Experience building production systems at scale with attention to reliability and performance
• Strong judgment about technical tradeoffs and when to optimize for speed vs. robustness
• Excellent communicator who can explain technical concepts to non-technical stakeholders

Nice to Have

• Experience with real-time communication systems, voice applications, or telephony
• Background in AI/ML product development, agentic systems, or integrating LLMs into production systems
• Prior work in logistics, operations, or enterprise SaaS
• Experience at an early-stage startup or as a founding engineer
• Open source contributions or side projects that demonstrate your craft
