Founding Engineer

This is a first engineering hire opportunity at an early-stage B2B SaaS company building an agentic integration platform for enterprise customers. You'll own core systems end-to-end and set the engineering patterns that every future teammate will build on — working shoulder-to-shoulder with the founders to ship production-ready software from day one.

What You'll Do

• Own the agent platform, infrastructure, and integrations runtime from end to end.
• Define the engineering standards and patterns that the growing team will inherit.
• Partner directly with the founders, contributing technical opinion and leadership — not just code.
• Ship to production continuously, delivering reliable and observable systems to paying enterprise customers.

• 3+ years of software engineering experience, ideally in fast-paced startup environments.
• Demonstrated ability to build something 0-to-1, whether at an early-stage company or through a serious side project.
• Proficiency in TypeScript and React for frontend development.
• Proficiency in Node.js for backend development.
• Hands-on experience integrating or building workflows around large language models (LLMs) and agent-based platforms.
• Experience with AWS for cloud infrastructure and PostgreSQL for data storage and database design.
• Track record of owning end-to-end feature development across frontend, backend, and infrastructure with measurable customer impact.
• Experience implementing observability, monitoring, and tracing in production systems.
• Experience building reliable retry and queuing patterns in distributed systems.

Salary range: $150,000 – $250,000 USD annually. Visa sponsorship is available.
