Data doesn’t equal insight, structure does.

At Cap, we’re building the AI-native operating system for modern venture funds. Today, investors are buried in pitch decks, portfolio updates, investment agreements, due diligence docs, and scattered meeting notes. All siloed across different tools and platforms.

Instead of switching between Affinity, Google Drive, and Notion, Cap gives venture capital firms a single, structured platform that organizes, understands, and prioritizes information. A connected workspace that provides the clarity investors need to make informed decisions.

As a Backend Developer, your job is to take messy, unstructured inputs and turn them into reliable, well-designed systems and features. From parsing documents at scale to building workflows that bring order to noise, you’ll be at the core of creating the structures that make Cap possible.

What you’ll do

• Parse messy inputs at scale → build pipelines to process 100,000+ PDFs, decks, and notes weekly, extracting the insight from the noise

• Architect real-time workflows → design APIs and services that deliver structured results in milliseconds

• Ship investor-facing features → take ownership from prototype to deployment, replacing fragmented tools with one cohesive platform

• Work with cutting-edge AI models → experiment with Claude, GPT, and other models - deciding when to use them, and when not to

• Collaborate directly with engineers and investors → turning live feedback into shipped product fast

  
  

What we value

Information is everywhere. Insight is rare. We hire for those who can build the structure that turns one into the other.

• Ambition → you want to build something big

• Imagination → you see possibilities where others see limitations

• Curiosity → you question, learn, and explore constantly

• Grit → you push through hard problems and keep going

• Skill → you can turn ideas into production-ready systems

• Helpfulness → you raise the bar for the team, not just yourself

  
  

What we’re looking for

• Strong engineering fundamentals: system design, data modeling, testing

• Proficiency in at least one backend language (preferably TypeScript and/or Go)

• Familiarity with APIs, databases, and cloud infrastructure

• Interest in AI/LLMs (production experience a plus, curiosity essential)

• A collaborative mindset: you thrive on building together, not just alone

  
  

Why join Cap

• Be part of the core team shaping an AI-native product from day one

• Work on hard problems: large-scale document parsing, real-time systems, structuring unstructured data

• Join a venture-backed startup ($2M pre-seed raised, 300+ VCs on our waitlist)

• Competitive salary + warrant program

• Build fast, learn fast, and be surrounded by ambitious teammates who value structure as much as you do

  
  

The process

• Initial screen (+ team fit and culture conversation) (60 min)

• Technical deep dive (60 min)
