Extend is building a modern document processing platform. We're on a mission to transform how the world works with unstructured data.
We’re hiring a Growth Engineer to join our founding team and own technical distribution. This role sits at the intersection of engineering, product, and GTM, and is focused on shipping real technical artifacts that earn developer attention and drive adoption.
This is a hands-on engineering role. You will be writing code.
We grew revenue 400% last year, with growth continuing to accelerate
Extend is used in mission-critical workflows at companies like Chime, Flatiron Health, Brex, Opendoor, Checkr, and more
The document processing market has expanded 1000× due to LLMs — and existing solutions are brittle and low-trust
We punch far above our weight with a lean team — every hire has outsized leverage
We’re solving novel problems at the intersection of LLMs, evals, complex data pipelines, and human-in-the-loop systems
Backed by world-class investors (YC, Homebrew, investors from OpenAI, and more)
You’ll work directly with the CEO, CTO, and founding team with real ownership
Document processing is exploding. Developers are actively evaluating tools and asking: what actually works?
Your job is to answer that question publicly and credibly.
This role exists to:
Own technical distribution for Extend
Build artifacts developers trust because they can inspect and test them
Shape how the market understands document processing, OCR, and extraction
Success looks like shipping projects that drive real usage, pipeline, and category leadership — not vanity metrics.
You will build and ship technical growth experiments end-to-end.
Responsibilities include:
Build public-facing technical projects (e.g. OCR Arena (ocrarena.ai), benchmarks, demos, microsites)
Design and run benchmarks for document processing (accuracy, latency, cost, tradeoffs)
Ship technical demos, reference implementations, and eval harnesses
Write production-quality code across the stack
Own projects from idea → build → launch → iteration
Instrument experiments and tie them back to adoption and revenue impact
Partner closely with Engineering, Product, and GTM
Move fast, test aggressively, and kill ideas that don’t work
You likely have:
Strong engineering fundamentals and experience shipping real systems
Comfort working across the stack (frontend, backend, infra, data)
Experience with APIs, datasets, evals, or developer tooling
Background in high-growth startups or highly ambiguous environments
Ability to communicate clearly with a technical audience
You might have:
Built tools, benchmarks, or demos that became externally useful
Written technical content grounded in systems you actually built
Shipped side projects that attracted real developer usage or attention
Worked at the intersection of product, engineering, and growth
You definitely have:
High agency and velocity
Strong technical taste (signal > noise)
A founder mentality — no task is beneath you
Obsession with outcomes, not activity
