Founding Engineer (Recent Grad)

What we do

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 from top investors, and are already deploying Ambral within multi-billion dollar enterprises. Now we’re growing our team to go supersonic.

What you'll do

As a founding engineer at Ambral, you’ll operate at the cutting edge of applied AI with extreme technical and strategic ownership. You’ll build digital twins to model human baselines and predict behavior, orchestrate complex systems of agents, tackle novel distributed systems problems, and work on a platform that looks as futuristic as our mission statement sounds.

You'll work directly with the CTO on all parts of the platform, ranging across:

* Developing Ambral's 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).

* 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.

Who you are

* You have experience in full-stack development with distributed architectures

* 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
