Senior Founding Engineer

Ambral•New York City, NY

2d•Onsite

About The Position

Ambral builds digital models of people and teams that predict what they’ll do next. Enterprises use these “digital twins” to synthesize signals across product telemetry, support interactions, emails, calls, and operational systems into a coherent understanding of each customer. Our agents then enrich missing context, recommend next-best actions, and execute workflows to help teams deliver the optimal experience for every customer. We graduated from Y Combinator Summer 2025, raised millions in funding, and are already deploying Ambral within multi-billion dollar enterprises. Now we’re growing our team to go supersonic.

Requirements

3+ years of experience in full-stack development with distributed architectures
Built ai systems / pipelines and understand the reliability and observability considerations surrounding them
Worked on systems that process and transform massive amounts of data
Capable of making practical tradeoffs to ship things fast that work, while making architectural decisions that allow us to come back later and scale the system
Good at explaining complex ideas to non-technical people
Love moonshot ideas that feel like magic (eg. realtime UX)
Think big and get excited by problems that feel impossible to solve
Looking to do the best work of your life and build something you'll be proud of for decades

Responsibilities

Develop the core platform to ingest data and synthesize “digital twins”, as well as the agentic systems to act on it (eg. Voice, SMS, and Email agents).
Work directly with the CTO on all parts of the platform, ranging across: Memory (how do we represent and refine our customer models?), Detection framework (what are the right primitives for building detection agents?), Agent design (how do we turn signals into reliable autonomous actions?), Distributed systems (how do we run 5000 agents in parallel?), Evals (how can we guarantee our agents are always getting better?).
Interface directly with our customers and own engagements end-to-end.
