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.
