About the job
Build and own backend-heavy product systems, data infrastructure, external integrations, and agent-driven automation while mentoring an engineer and shaping engineering practices.
What you'll do
- Build lifecycle event data infrastructure and an agentic system that assesses operations and executes improvements.
- Own full-stack delivery of the core product, emphasizing backend, infrastructure, and reliable external-platform integrations.
- Mentor an engineer, contribute code daily, and help shape the team's engineering practices.
What they ask for
- Experience building agentic or LLM-powered systems connected to external APIs and taking AI-driven software from design through live operation.
- Background at a fast-scaling startup joined before it became a large organization.
- Strong server-side and full-stack skills, especially in pipelines, event flows, and external-service integrations; experience leading or mentoring engineers.
- 3 or more years of professional engineering experience.
Nice to have
- Experience with commerce or marketing platform APIs.
- Experience building a product from scratch as an early team member or first hire; strong engineering pedigree from a leading university may offset a shorter fast-scaling-company record.
