Software Engineer, Platform

Ambrook • San Francisco, CA

2d • $115,000 - $280,000 • Remote

About The Position

Ambrook is rebuilding the financial infrastructure for American family-run businesses, helping them become more profitable and resilient. We are a Series A startup backed by prominent investors, seeking early team members to join us in untangling the intersection of American industry, climate, and the economy. Our platform engineers build the foundational systems that enable the rest of the company to develop Ambrook more effectively. This role involves working across product infrastructure, including PostgreSQL databases and GCP environments, as well as company infrastructure such as internal tooling, data platforms, and systems powering internal AI workflows. The primary technology stack is TypeScript, with opportunities to learn GCP scripting. This position requires a blend of strong infrastructure judgment and a product-oriented mindset. You will collaborate with engineers and non-engineering teams who rely on the platform, iterate rapidly based on their feedback, and uphold the quality, security, and scalability standards essential for Ambrook's dependable growth. A key aspect of this role is building the infrastructure for Ambrook's agentic systems, focusing on shared frameworks, evaluation systems, loops, harnesses, sandboxes, and interfaces that empower internal teams and product teams to build and operate agents confidently. The goal is to create a system where any team can request, deploy, evaluate, and monitor agents, thereby enhancing employee experience and expanding the company's shipping capabilities.

Requirements

• Built and operated production platform or infrastructure systems.
• Hands-on experience in PostgreSQL and GCP.
• Planned and run migrations at scale, including validation, observability, and rollback strategies that protect production systems and customer data.
• Enjoy platform work and look for changes that improve the whole codebase, developer experience, or tooling rather than a single feature.
• Treat engineers and non-engineering teams as platform customers. Learn how they work, build with empathy, and iterate from real feedback.
• Comfortable building the interfaces and supporting product surfaces that make infrastructure useful to internal teams.
• Security-minded and consider access, data handling, failure modes, and operational risk as part of ordinary engineering work.

Nice To Haves

• Built infrastructure for agentic systems, such as evals, agent loops, harnesses, or sandboxes, rather than only building individual agents.
• Experience working directly on application security or infrastructure security.
• Experience building financial products or systems where auditability and data integrity matter.
