Develop and enhance the core platform and agentic systems for digital twins, working closely with CTO and customers.
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).
- You'll 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?)
- You’ll also interface directly with our customers and own engagements end-to-end.
Requirements
- You have 3+ years of experience in full-stack development with distributed architectures
- You’ve built ai systems / pipelines and understand the reliability and observability considerations surrounding them
- You’ve worked on systems that process and transform massive amounts of data
- You’re 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
- You’re good at explaining complex ideas to non-technical people
- You love moonshot ideas that feel like magic (eg. realtime UX)
- You think big and get excited by problems that feel impossible to solve
- You're looking to do the best work of your life and build something you'll be proud of for decades
Conditions
- Equinox membership
- Free meals, coffee, and snacks
- Health insurance
- Unlimited PTO
- Relocation assistance to NYC available
- This is an in-person role in New York.
Other
- 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.
